Hailong Wang's Expertise Tapped for Guardian's Arctic Soot Reveal
Reducing soot emissions to the Arctic would be a ‘quick win,' said an article in The Guardian online. Sought for his research knowledge, Dr. Hailong Wang contributed to the story by citing both observational and modeling evidence: soot is warming the Arctic. The article "Why cutting soot emissions is 'fastest solution' to slowing Arctic ice melt," published online in December, reviewed why cutting soot emissions may be the cheapest and fastest way to combat climate change.
"The warming effect could be through the direct heating to the air, snow and sea ice by absorbing sunlight, and then accelerating the melting of snow and sea ice," Wang said. "When the melting starts, there are positive feedback processes that can lead to even faster melting."
The positive feedback Wang spoke of is the effect when melting starts, forces are set in motion to speed up the melting. The warming reinforces itself.
"Unlike greenhouse gases, soot particles are relatively short-lived in the atmosphere," said Wang explaining a key difference between greenhouse gases and soot. "The average lifetime is around a week or two," said Wang. "New snowfall [can also] cover them [the soot particles] pretty quickly."
The article also explains that near-term warming is a problem requiring speedy solutions. But the benefits can happen relatively quickly.
Wang is a climate modeler focused on atmospheric particles such as soot, and how they travel around the globe and end up in the Arctic. He led the development of a source-tagging technique in a global climate model that quantifies the source-receptor relationships of carbon-based particles to understand their effects on climate warming. He holds a PhD from the University of Illinois at Urbana-Champaign.January 2017
Ghassem Asrar Quoted in EOS on Way Forward
Dr. Ghassem Asrar of Pacific Northwest National Laboratory was quoted in an Eos article after the close of the American Geophysical Union's 2016 Fall Meeting. The article, "Scientists Ponder the Way Forward Under Incoming Administration," questioned several attendees at the meeting to sample reactions to the recent U.S. national election.
Asrar believes in using science to serve humankind. "Earth observations provide societal and economic benefits, for example, for agriculture, fishing, and shipping. It's [about] how we can take advantage of science and technology to serve us and the rest of the world," he said.
Asrar is the director of the Joint Global Change Research Institute located in College Park, MD, an organization jointly sponsored by PNNL and the University of Maryland. His research focuses on understanding earth science using remote-sensor capabilities, including Earth-orbiting satellites, to provide fundamental insights into the connections between Earth's land, oceans, atmosphere, ice, and life. In previous positions, he has served as Director of the World Climate Research Program, the Agricultural Research Service, the U.S. Department of Agriculture, and the U.S. National Aeronautics and Space Administration.
With advanced degrees in soil biophysics, civil engineering and environmental physics from Michigan State University, Asrar commands a broad understanding of Earth and climate change topics.December 2016
PNNL's Steven Smith Quoted on Coolant's Hot Topic
Scientists are exact with their numbers. Many others—including some politicians—tend to round. In Kigali recently, political leaders leveraged a 0.5°C potential savings in global warming to adopt policies that will limit the use of hydrofluorocarbons (HFC) worldwide. Some scientists, although they are in favor of the policy, thought the number was unscientifically ambitious.
Science Magazine turned to Pacific Northwest National Laboratory's climate modeling specialist Dr. Steven J. Smith of the Joint Global Change Research Institute, for some insight. Regarding the scientists' work, Smith said. "They've clearly done the best work on this to date."
The work he's referring to comes from a 2013 paper that forecasts how as developing countries use more refrigerating coolant, the HFCs will push global temperatures up 0.35°C to 0.5°C by 2100. These numbers, according to the article, are substantially higher than HFC warming made by other climate models.
Smith also told Science that more sophisticated models that offer a range of possible futures, such as different patterns of economic growth, could improve such estimates.November 2016
Article Makes Analyst 2016 Hot Original Research List
PNNL research snags the March cover of Analyst.
A team of researchers at PNNL are warming to the news that a January article of theirs was named to a list of "hot original research articles" of 2016 by Analyst, the journal of the Royal Society of Chemistry. "Hurray," said bioanalytical chemist Erin Baker in an email, "it has been a good week."
Grabbing the honor for them was "Uncovering biologically significant lipid isomers with liquid chromatography, ion mobility spectrometry and mass spectrometry." The paper outlines a breakthrough analytical technology approach to analyzing the biological roles lipids play. It is known, for instance, that lipid metabolism is linked to type 2 diabetes, cancer, and lipid storage disease.
But getting to the functional details of those links is problematic. Mass spectrometry, the currently dominant approach for analyzing the lipidome, presents challenges when used by itself. But coupling it with liquid chromatography and ion mobility spectrometry as described in the manuscript shows great promise for enhanced measurements.
Other scientists at PNNL share credit for the paper: Xing Zhang, Karl Weitz, Matthew Monroe, Yehia Ibrahim, Thomas Metz, and Richard Smith. The paper also included collaborators from Cincinnati Children's Hospital and the University of Washington.October 2016
Fredrickson on the Chemistry of Microbiomes Seminars
Microbes make up most of the planet's biomass, living in collaborative communities called microbiomes, which thrive on land, at sea, and within ourselves. They catalyze chemical reactions affecting the health of the Earth's ecosystem and of every human. But many mysteries remain for scientists studying these little worlds of large import.
"The Chemistry of Microbiomes" will help. PNNL geomicrobiologist and Laboratory Fellow Jim Fredrickson said the next seminar in the series will be webcast from 2 to 5 p.m. (ET) Wednesday Oct. 19 in Washington, D.C and will focus on the microbiome of marine habitats. It is the second of four seminars sponsored this fall by the Chemical Sciences Roundtable at the National Academy of Sciences and by the Department of Energy. (On the roundtable board is Allison Campbell, Associate Laboratory Director for Earth and Biological Sciences at PNNL.)
Fredrickson is on the planning committee and is one of three chairs in the series. In September, he oversaw the first seminar, on the terrestrial microbiome. This "expansive and diverse" habitat for microbes, Fredrickson explained to a combined audience of 180, includes niches within the Earth's crust, in soils, and in terrestrial-aquatic interfaces - "very special regions," he said, and "very important factors for sustaining the environment."
Importantly, there are also the Earth's little appreciated subsurface terrestrial microbial habitat, Fredrickson said, where there is "more biomass beneath our feet than exists collectively on the rest of the planet." His remarks, along with three other expert presentations, were captured on video.
Following the Nov. 9 seminar (on the human microbiome), Fredrickson will speak at an all-microbiome final seminar on Dec. 7. A proceedings on the whole series, he said, will be published "sometime after the first of the year."October 2016
For NAS, Jansson Weighs in on Microbiomes of the Built Environment
Mouse gut cryo-section, showing the host intestinal epithelial cell nuclei (red) and the bacteria in the lumen (green).
Microbiologists fervently study the teeming and complex microbiome of both soils and the human gut. But not so much the interiors of the built environment, where most humans spend 90 percent of their time. Homes, hospitals, workplaces, transit systems, and other constructed interior spaces are similarly inhabited by ubiquitous and invisible communities of bacteria, viruses, and fungi.
Microbial ecologist Janet Jansson is part of a 20-month study underway on microbiomes of the built environment sponsored by the National Academy of Sciences (NAS). Executing the study, in part through a series of national meetings, are experts in microbial ecology, building science, public health, and related fields. On Oct. 17 and 18, Jansson - a renowned researcher of both soil and gut microbiomes - will be at the University of California, Irvine for NAS's third meeting on the issue.
The largely mysterious life of microbiomes within built environments is both important and little studied (though the effects of indoor mold are well known). Inside constructed environments, most microbial communities are non-pathogenic, thriving peacefully on surfaces and within air and water systems. Nonetheless, resident microbiomes can have both good and bad effects on how long built environments last, how energy efficient they are, how they must be maintained, and how conducive they are to human health.
During the meeting's first panel, Jansson will be the first of three scientists delivering remarks on how the built environment responds to "context and perturbations". She will discuss microbial community response to environmental conditions, and will describe the research mission of Microbiomes in Transition, an initiative she directs at PNNL.
The dynamics of microbes in the built environment were also explored at a 2015 symposium held by the American Association for the Advancement of Science.
IEEE Pulse Profiles Microbial Ecologist Jansson
PNNL microbiologist Janet Jansson, a leading international figure in microbiome research, was profiled in the latest issue of the journal IEEE Pulse. "Omics Tech, Gut-on-a-Chip, and Bacterial Engineering" featured three new approaches to studying a suite of gastrointestinal illnesses called inflammatory bowel diseases (IBDs), which impact at least 1 million Americans and many more worldwide.
In the lead profile, Jansson represented those researchers investigating such diseases by using omics technologies - uncovering the DNA sequences, expressed genes, and metabolite signatures used to reveal links to microbial functions in the gut. At PNNL, she leads research into the microbiome, a term for the collective communities of microbes that reside in many environmental niches, including the human gut and soil.
To address IBD, Jansson's team has collaborated with bioinformaticians to integrate overwhelming amounts of new genetic data, and has published studies comparing healthy microbiomes to those in IBD patients - all with the aim of future diagnostics and potential new therapies, she said.
Six years ago, Jansson was part of a landmark case demonstrating the use of fecal transplantation to counter diseases of the human gut affected by dysfunctional microbial communities. She participated by profiling a patient's gut microbial community both before and after the transplantation.
"In that case, the patient was in really bad shape," Jansson told the journal. She was losing weight, wearing diapers, and unresponsive to antibiotic treatments.
The positive outcome "was a wonderful and rather unusual example of introducing a microbial community into a new environment," said Jansson, "where it was able to establish and have a major impact." Since then fecal transplants have been successful in treating infections by the bacterium Clostridium difficile.
Beyond that, Jansson and her colleagues are investigating the impact of a high-fiber diet on the gut microbiome. Such a diet appears to encourage a higher percentage of beneficial organisms. Her PNNL team uses multi-omics to identify the proteins and metabolites made by those beneficial organisms. Ultimately, she said, a "designer diet" could be used to optimize a person's gut microbiome.
Also featured in the story were two researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard, Donald Ingber (for his "gut-on-a-chip" model of intestinal inflammation and bacterial overload) and Pam Silver (for her her work on engineering bacteria as biomarkers of inflammation).
Jansson got the feature's last word, noting how important it is to address diseases so prevalent in those who follow a Western diet - and how important it is to understand the connection of such diseases to the microbiome.
In the course of the IEEE Pulse feature, she joined the Wyss Institute's Silver in being impressed by the number of disease phenotypes linked to the gut microbiome, pointing to suggestive studies on autism, certain cancers, and rheumatism. Jansson is also leading an investigation funded by the Office of Naval Research on how the gut microbiome influences the brain.October 2016
Arun Devaraj Featured in PNNL Director's Column in Tri-City Herald
Arun Devaraj using an atom probe tomography system, or APT, one of the specialized instruments at EMSL, to create an atomic map of how individual atoms in a titanium alloy are arranged.
Pacific Northwest National Laboratory materials scientist Arun Devaraj was featured in Lab Director Steve Ashby's monthly column in the Tri-City Herald. In "Making better stuff," Ashby described materials research at PNNL.
Arun and his colleagues at PNNL use atom probe tomography, a high-resolution 3-D imaging capability, to study automotive and energy materials. The insights about these materials and their behavior can help scientists and engineers achieve lightweight vehicles and help develop new energy storage technologies. Arun began working at PNNL as a postdoctoral researcher in 2011 and became a senior research scientist in 2012.September 2016
ISME16, Now History, The Most Epic Thing Ever
French microbiologist Adrien Assié sketched his way through ISME16, and departed on Friday with this tweeted sentiment.
All good things must come to an end, even the 16th international symposium hosted by the International Society for Microbial Ecology (ISME) from Aug. 22-26 in Montreal.
Society president Janet K. Jansson joined 14 other PNNL researchers at the signature event, held every two years. With the vast Palais des congrès de Montréal as a venue, the conference celebrated professional exchange and education with over 300 presentations, 800 posters, and more than 2,100 attendees from around the world. It was the largest symposium in the society's 40-year history.
By the end, there were some strong reactions. "ISME16 was without a doubt the most epic thing ever," wrote Biological Sciences Division post-doc Richard A. White III in an email. "No other conference is even in the same ballpark. Or will even be close to it - WOW!" A prolific author already, he works with Jansson on advances in analyzing soil microbiomes.
Over the five days of ISME16, a garden of tweets grew up and flourished on the internet. After one particularly lively session, one researcher tweeted, "Mind = Blown (for the 100th time this week)."
Mary S. Lipton, a senior staff scientist at PNNL, had a role in the mind-blowing magic. On Friday (Aug. 26), the conference's last day, she took to the podium with "Deciphering microbial community interactions through succession," which acknowledges 17 PNNL co-authors.
The talk confronted a stubborn fact: Microbial communities, and the autotroph-heterotroph interactions they rely on, influence biogeochemical cycles on a global scale. But the molecular mechanisms behind these interactions are largely unknown. After all, highly diverse and complex natural systems are very difficult to control in laboratory settings. To elucidate the principles governing these natural systems, researchers need them to be "tractable" - that is, easy to control.
To address that challenge, Lipton explained, the PNNL researchers developed an experimental platform that simplifies manipulation and observation. This model consortium of autotrophic and heterotrophic microorganisms experiences metabolic shifts over a 28-day succession cycle. In seven-day intervals, researchers recorded the consortium's patterns of organism abundance and protein expression. Next, she said, the researchers will use metabolic models of other consortia to infer "interaction maps."
On the PNNL campus, Lipton is the capability lead for mass spectrometry at the Environmental Molecular Sciences Laboratory (EMSL). So a plug was in order for the specialized capabilities at this national scientific user facility. One of her slides listed 23 EMSL instruments, specialties, and other attractions, from confocal microscopy and cell isolation systems analysis to microfabrication fluidics.
Lipton was in good company among those making Friday presentations. Other researchers touched on cellulose degradation in landfills, cow-gut resistance to antibiotics, iron cycling in lake snow, fungal gardens, plant-microbe interactions, leaf bacterial diversity, fleshy algae in coral reefs, microbial carbon capture systems, and the bounteous life of microbes in Antarctica's frigid, hypersaline Lake Vida.
University of Colorado evolutionary biologist Noah Fierer packed the house with a talk on how perturbed soils survive. Steven Biller, a research scientist in the Chisholm lab at the Massachusetts Institute of Technology, spoke about extracellular vesicle production in marine bacteria. And microbiologist Adrien Assié (@m3thyl) dove into his cool ocean research into epibionts that live on the surface of a genus of deep-sea mussels called Bathymodiolus. It was Assié who also sketched his way through the conference, then broadcast his quick portraits of presenters via Twitter.
"Fantastic meeting!" tweeted PNNL's Vanessa Bailey, crediting Jansson and her ISME16 team. She used another tweet to comment on a sketch by Assié, who trained in France and works in Germany. At the conference, a long line of posters listed attendees by country.
"At any given time," said White, the PNNL post-doc, "I was talking with a group of scientists from five different continents."
Friday afternoon presentations by two keynoters drew big crowds. Molecular biologist Siv Andersson of Uppsala University in Sweden, who studies how intracellular bacteria and organelles evolve, delivered a plenary talk on bacterial symbionts, including an explanation of why mitochondria contain a genome. McMaster University health science researcher Gerard D. "Gerry" Wright told the science story of antibiotic resistance. To microbes, he observed, antibiotics are more weapons than anything else.
Heavy stuff. But more than one tweet busted the many scientists who used Montreal and ISME16 to play the mobile game Pokémon Go. Someone else took the time to invent a 16-square "ISME Bingo." Among the choices: "n=1," "acronym for new tool," and "mockery from outside fields (e.g., physics)."
At day's end, Jansson gave out poster awards, with James Blunt's "You're Beautiful" as a soundtrack. She also handed over the ISME reins to incoming president Colin Murrell, a British environmental microbiologist who teaches at the University of East Anglia. "There is one person we really need to thank - Janet Jansson," he told her on stage. "We've been extremely fortunate to have your guidance."
ISME17 will be held in August of 2018 in Leipzig, Germany. And in 2020, ISME18 - "Brilliant!" one tweeter crowed - will be in Cape Town, South Africa.
By Friday evening the ISME16 Twittersphere had quieted. But one researcher tweeted that he would remember the symposium this way: "peeking in on all the cool stuff."August 2016
At ISME16, It was Time for Young Researchers to Poster Up!
PNNL post-doc Taniya Roychowdhury, who was first author on two of the laboratory’s 10 main posters at ISME16, talks to a viewer at the Montreal conference.
At professional conferences, posters are a chance for mostly young researchers to strut their science stuff when they can't chair a roundtable or present a full lecture.
So it was on the second-last day of this year's 16th international symposium on microbial ecology hosted by the International Society for Microbial Ecology in Montreal. During the Aug. 22-26 symposium (Monday, Tuesday, and Thursday), 500-plus posters were on display, including 10 offerings by PNNL lead authors and 13 others that listed PNNL contributors.
On each of those three days three outstanding posters were chosen as ISME16 winners. PNNL researchers were not among those. But the nine winning authors got free 2017 ISME memberships, opening the way for them to attend the 2017 symposium, slated for August in Leipzig, Germany.
During the day, considerable last-minute energy around posters tore up the Twitter airwaves. Dozens of pictures stormed into sight, along with pleas to take a look. "Shameless promotion time," one began. "Tonight! Tonight!" another promised. Then came the classic "Poster up!" which was followed by an invitation to chat about growing fungi in microfluidic systems.
One tweeted image said it all about the week's good-natured poster competition. It showed two post-docs having a boffo sword fight. With, of course, rolled-up posters.
Many poster topics were certainly compelling. They included investigations of boreal shield lakes, urban soil bacteria, and the skin microbiome of cohabitating couples.
Among PNNL posters, sober and deep ruled the day. Here are the 10, with only lead authors listed:
- "MetFish: A suite of chemoselective tags combined with tandem mass spectrometry for quantitative and comprehensive metabolomics analyses in extreme ecosystems." Chengdong Xu (now at Hexion, Inc.; corresponding author Thomas Metz).
- "Carbon mineralization through alcohol production in high-carbon freshwater sediments." David Hoyt.
- "Emergent responses of microbial partnership; acclimation and coordination in a model phototrophic-heterotrophic consortium." Hans Bernstein.
- "Changes in microbial community and metabolite composition in permafrost thawed under aerobic and anaerobic conditions." Eric Bottos.
- "Still counting the uncountable: effect of soil volume size on bacterial diversity estimates." Taniya Roychowdhury.
- "Prediction of interspecies interactions in model complex microbial consortia using a combined analysis of species abundances and genome-scale functional annotation. Is two better than one?" Hyun-Seob Song.
- "Context-based mutual information networks for understanding coordination of microbial community behavior." Alexander Beliaev.
- "Nitrogen source governs carbon partitioning among members of a model phototrophic consortium." Steve Lindemann (now at Purdue University; corresponding author Janet Jannson).
- "Exploiting multi-omics to decipher soil microbiome responses to perturbations." Taniya Roychowdhury.
- "When deeper and greater depth of sequencing fails for complex soil metagenomic assembly - conquer it with Moleculo." Richard White III.
Near the End, ISME16 is Crowded and Energetic
At ISME16, PNNL’s Janet Jansson presides over Thursday night’s plenary session. She is president of the International Society for Microbial Ecology.
Only one professional conference in the world could yield this tweet: "Let's chat about susceptibility of the human gut to Vibrio cholerae."
The comma-shaped bacterium that lives in salty water includes strains that cause cholera. But Vibrio cholerae drew attention at a more cheerful venue: This year's 16th international symposium on microbial ecology, hosted by the International Society for Microbial Ecology in Montreal, which ends Friday (Aug. 26). The society's current president, PNNL's Janet K. Jansson, was there, along with 14 other attendees from the laboratory.
The Aug. 22-26 gathering in the Canadian island city has so far included hours of plenary sessions, invited talks, roundtables, award ceremonies, and chatter about posters. Just over 500 were on display, giving (largely) younger researchers a way to strut their science stuff.
Thursday (Aug. 25) was the symposium's second-last day. From the perspective of most PNNL attendees, there was little official activity, in contrast to the talk-heavy first two days of the week. Microbiology group manager Vanessa Bailey did Thursday's sole PNNL honors at a podium, chairing her second soil microbial ecology session of the week.
A late morning tweet showed conference-goers packed in a corridor, lined up to go into Bailey's session. The event got a Twitter bounce from the Federation of European Microbiological Societies, promoting a thematic joint issue of their journals on the ecology of soil microorganisms.
Also on Thursday the last of the PNNL swag disappeared: 100 Smartphone microscopes that clip on over the phone's camera. They were available free at the joint ISME16 display booth put up by the Environmental and Molecular Sciences Laboratory, located on the PNNL campus, and the Department of Energy's Joint Genome Institute.
With Jansson at the helm, the symposium drew more than 2,000 attendees from around the world - a number that one Thursday conference-goer tweeted "seems to have doubled today."
One reason may have been the day's lectures and roundtables. Researchers held forth on nitrification, gut pathogens, a giant novel virus from the deep sea floor, soil ecology, citizen science, the effect of climate change on maple syrup, and souring microbes in oil wells.
One much-tweeted talk was on the microbiome of moose rumen. It included a picture of one of the antlered Alces alces with a passageway cut from the outside into the animal's stomach, for purposes of painless study. "Behold, the fistulated moose!" tweeted Bailey. She called the session on rumen microbiomes (ideal for studying anoxic carbon degradation) "the most Canadian talk of the week."
The ISME16 Twittersphere on Thursday also included some popular observations, made in and out of talks. One researcher estimated that the Earth is inhabited by 1 trillion microbial species. Another had doubts about citizen science because "sometimes people say they're 6 inches tall." And many others repeated this nugget from one talk on fecal transplants (which mentioned a pill called "the crapsule"): It's hard to get enough fresh human poop for gut microbe experiments.
Or maybe ISME16 felt crowded Thursday because attendees were still energized by their day off on Wednesday. Mid-way through some conferences it's a tradition that attendees break away for local sightseeing and for collegial conversation in more casual settings.
So time-off tweets bloomed on Thursday, along with proof in pictures: hikes, favorite meals (one was hot dogs and poutine), public art in the island city, kayaking on the Lachine Canal, a culinary tour (which merited a picture of macaroons stacked in a bakery case), and many views of Montreal and the St. Lawrence flowing past. One such tweeted picture included a scientific note: "I sampled that river!"
But the sense that ISME16 felt crowded Thursday was most likely because of the day's true highpoint: the Tiedje Award Plenary Session, chaired by Jansson. In the spotlight was this year's award winner, Sallie W. "Penny" Chisholm, a biological oceanographer who has been at the Massachusetts Institute of Technology for four decades. She delivered an address that lit up the Twittersphere, "Tiny Cell, Global Impact: The Prochlorococcus Story."
Chisholm, who during the address related how she arrived at this signature microbe, has collaborated in spectacular discoveries regarding Prochlorococcus. This cyanobacterium is achingly tiny: just 1700 genes, 20 percent smaller than most algae, and about the size of the wavelength of light it absorbs in its solar-powered genome. It is also vastly abundant, sometimes accounting for half of the ocean's photosynthetic biomass. And oxygen-making Prochlorococcus is critical to the Earth's climate.
At MIT, Chisholm and her team investigate how oceanic microbes shape the marine environment, how they evolve, and how they influence global biogeochemical cycles. They are working on the bacterium as a model system for studying life across every scale of time and space.August 2016
Day Two of ISME16: Microbe Fans Unite
An ISME16 roundtable on soil metagenomics – one of PNNL’s own research strengths – resulted in this dauntingly crowded image, a tweet from Nature Microbiology.
On Tuesday afternoon Aug. 23, the following tweet went out from a conference hall in Montreal: "Being able to study plasmids in soils, rhizosphere is so exciting!"
You are right: The tweet was from the 16th international symposium on microbial ecology, hosted by the International Society for Microbial Ecology (ISME). Our own Janet K. Jansson is the group's current president and is among 15 PNNL attendees this year.
And right again: The tweet was from microbial ecologist Vanessa Bailey, who manages PNNL's Microbiology group in the Biological Sciences Division. She delivered one of three talks by PNNL scientists on Tuesday, the symposium's second of four days this week. (Attendees have Wednesday Aug. 24 off to sightsee and to confer offline.)
The Aug. 22-26 professional gathering at Palais des congrès de Montréal, dubbed ISME16, has drawn more than 2,000 attendees from around the world, including Austria, Brazil, Canada, China, Japan, New Zealand, and Russia. So far they have crowded into roundtables, invited talks, poster sessions, and other venues for exchanging information about the microbial universe, which affects the environment, our health, and the nature of Earth's climate.
The ISME16 Twittersphere on Tuesday was lively too, with tweets that occasionally strayed from enzyme profiles and diel cycling into the problems of managing microbiology and family at the same time.
During Tuesday's sessions, PNNL was represented at the podium by Bailey, who delivered a 30-minute talk to a very large audience; by EMSL chief scientist David A. Stahl, who holds a dual appointment at the University of Washington; and by Aaron Wright, a scientist and proteomics expert.
"Talk was great," Bailey reported later in a quick email. "I got some twitter love!"
And what was not to love? For one, the presentation title had a sonorous ring: "Integration of soil metagenomic and chemical data to identify microbial processes altered by simulated climate change after an 18-year soil transplant." Bailey and others published a paper this spring on the same experiment. The research was updated in the conference talk, and also acknowledged PNNL co-authors Lisa Bramer, Sarah Fansler, Nancy Hess, Alejandro Heredia-Langner, Lee Ann McCue, and Malak Tfaily.
Stahl delivered a talk on ammonia-oxidizing archaea (AOA), single-celled organisms that are part of an abundant domain of creatures morphologically similar to bacteria. AOA, fully described only 11 years ago, may be "major contributors to the atmospherically active gases methane and nitrogen oxides," wrote Stahl in an abstract. In his talk, he presented recent findings about how these consequential AOA microorganisms are distributed, and how they act, in natural systems.
Wright, a chemical biologist, delivered a talk entitled "Activity-based probing reveals new contributions for vitamin B12 in modulation of microbial protein activity and gene regulation." Within microbes and microbial communities, vitamin B12 is "a requisite and precious commodity," he wrote. Despite its importance, the many likely roles of vitamin B12 in microbial metabolism and gene regulation are not well understood. Wright described a strategy for learning more: an activity-based probe that mimics vitamin B12 and can be used to sweep up proteins likely tied to important microbial functions.
Wright's talk acknowledged his co-authors, including five from PNNL: Lindsey N. Anderson, Yukari Maezato, Thomas O. Metz, Premchendar Nandhikonda, and Margaret F. Romine.
Poster sessions are a staple activity at science conferences, giving voice to many new additional projects and research. At ISME16, with authors standing by, 10 PNNL posters are on display, including those that touch on microbial activity in thawed permafrost, prairie pothole region lakes, biofilm, and hypersaline ecosystems. Another 13 posters on display include contributions from PNNL scientists.
Aside from the speakers mentioned, other PNNL researchers joined Jansson at the symposium: Hans Bernstein, Eric Bottos, David Hoyt, David Koppenaal, Mary Lipton, Lee Ann McCue, Jim Moran, Ljiljana Pasa-Tolic, Taniya RoyChowdhury, Hyun-Seob Song, and Richard A. White III.
This year marks the 40th anniversary of ISME and the 10th anniversary of its influential journal.August 2016
With a President from PNNL, ISME Launches a Worldwide Symposium in Montreal
Conference swag. Photo courtesy of Vanessa Bailey.
Microbes and Montreal. What could bring together Canada's second largest city and the tiny organisms that (arguably) rule the environment, health, and even Earth's climate?
The answer: This year's 16th international symposium on microbial ecology, hosted by the International Society for Microbial Ecology. PNNL's Janet K. Jansson is the group's current president and is among 15 attendees from the laboratory, many of whom will take to the podium.
The Aug. 22-26 gathering in French-speaking Montreal is a busy science gala of plenary sessions, invited talks, and roundtables. More than 2,000 attendees, including a woman who wore an "I (Heart) Microbiomes" T-shirt on the first day, will spend time puzzling over soil microbes, extreme environments, pathogen ecology, the mammalian microbiome, and much more. (The oral sessions alone number 57.)
Joining Jansson at the symposium from PNNL are Vanessa Bailey, Hans Bernstein, Eric Bottos, David Hoyt, David Koppenaal, Mary Lipton, Lee Ann McCue, Jim Moran, Ljiljana Pasa-Tolic, Taniya RoyChowdhury, Hyun-Seob Song, David A. Stahl (who holds a dual appointment at the University of Washington), Richard A. White III, and Aaron Wright. This week, microbiome researchers Bailey and Wright will both lead convened sessions and present invited talks.
PNNL's Moran did the early honors on Monday with a brief late-morning talk on diel carbon flow dynamics within photoautotrophic microbial mat communities. (They capture energy from the sun to make their own food, converting carbon dioxide into organic compounds at the same time.) "Diel" denotes a cycle of 24 hours; "carbon flow dynamics" is a hot topic among researchers trying to map how carbon moves through an aquatic ecosystem, including how it might be influenced by a "loop" of microbial communities.
Mid-afternoon Monday, PNNL's Bernstein, a scientist specializing in microbial communities, presented Poster No. 462A (another sign of how large the symposium is). "Emergent responses of microbial partnership: Acclimation and coordination in a model phototrophic-heterotrophic consortium" was one of seven themed conference posters on communication and networks on biofilm communities. It cited four PNNL co-authors.
To cap off the first day, there were two simultaneous late-afternoon events related to PNNL.
Stephen R. "Steve" Lindemann (at PNNL until this summer and now an assistant professor at Purdue University) led a roundtable on model communities and whether they can be used to discover generalizable principles in microbial ecology. The event was co-organized by PNNL's Alex Beliaev.
Stahl and Koppenaal led a roundtable on the technology landscape of microbial systems research, a companion event to an oral session entitled "Cutting-edge methods in microbial ecology," convened by PNNL's Wright. The roundtable panel included Bailey, Pasa-Tolic, and Wright.
For a late session, one observer said, the audience was big: about 75 people. Most were interested in accessing and applying fast-emerging advances in computational and analytical capability, particularly those available through Department of Energy (DOE) national science user facilities.
Two of these figured prominently in the discussion: the Environmental and Molecular Sciences Laboratory (EMSL) located on the PNNL campus and DOE's Joint Genome Institute (JGI). Stahl and Koppenaal, respectively, are EMSL's Chief Scientist and Chief Technology Officer.
EMSL and JGI will have a joint display booth open all week at the symposium. Monday morning, this is how it looked.
Too bad, though: The video shows no sign of the researcher with the "I (Heart) Microbiomes" T-shirt. But the symposium has four microbe-celebrating days to go. Check this space for daily updates.August 2016
Brian Thrall Honored in NIEHS Feature for PNNL Nanotoxicology Work
That was the basic message of an Aug. 22 feature story published by the National Institute of Health Sciences (NIEHS) about the work of Brian D. Thrall and his PNNL colleagues. Brian manages the Health Impacts and Exposure Science group in the Biological Sciences Division and directs the laboratory's NIEHS-funded Center for Nanotoxicology.
NIEHS, the environmental research arm of the National Institutes of Health, publishes a "Success Stories" series about outstanding research directions its grantees pursue. In this case, it was Thrall's work on the potential health effects of engineered nanomaterials (ENM), so tiny that they are typically one-thousandth the width of a human hair. ENM are increasingly used in biomedicine, food packaging, and other industries with direct contact to consumers.
Exactly how ENM reach and affect human cells is little known, so Thrall's multidisciplinary team is ferreting out potential health risks by employing the latest techniques in proteomics, imaging, bioinformatics, and other specialties.
Thrall and his team are going beyond the big issue of oxidative stress and cell death to pursue the effects of ENM at low levels - what Thrall refers to as "the early targets and downstream impacts of oxidative stress."
They developed and have applied quantitative redox proteomics, a novel technique that identifies changes in cellular proteins with enhanced specificity and sensitivity. The feature pointed to "technical innovations" led by PNNL's Wei-Jun Qian.
Present work by the group is focused on testing a broader range of ENM for toxicity potential and on research towards a future predictive nanotoxicology framework.August 2016
For BioTechniques, Janet Jansson Weighs in on Science's Ways of Unlocking Microbial Communities
Vastly ubiquitous microbial communities live on, in, and around everything on Earth, from within the human gut to across the biggest ocean. But they are as little known as they are vital to life, health, and the environment. In soil alone, 99 percent of microbial species have yet to be isolated.
PNNL microbiologist Janet K. Jansson was just quoted at length regarding the stubborn mysteries of microbial communities, which can be good or bad for the ecosystems they populate. "There are many unknown unknowns," she said in a feature story released in the August issue of BioTechniques. Among nine scientists quoted or cited, she was the most frequently heard.
Up front, the story outlined the challenges of understanding the structure and function of microbial communities. Then it outlined in detail the techniques researchers are using to make headway. Carrying the narrative thread was one frontier of research in particular: biofilms, the largely bacterial multicellular communities that colonize surfaces everywhere.
Every bacterium plays a role in these layered ecosystems, within a diversity of chemical and physical environments. Up close, the feature said, biofilm structures are city-like, "with water channels and skyscrapers, mushroom shapes, or thick layers peppered with pores."
Cell by cell, even single-species biofilms are complex, so scientists have gone beyond simple chemical analysis to a variety of tools that help investigate the spatial and temporal relationships of these cooperating cells.
Researchers use imaging mass spectrometry to get a two-dimensional picture of biofilm surfaces; vibrational spectroscopy to get at the chemistry of biofilm polymers; fluorescence microscopy to show biofilms down to the resolution of a single cell; and something called spinning disk confocal microscopy to examine biofilm cells up to 35 microns deep, a 10-fold improvement over previous techniques.
But scientists, Jansson among them, want to go beyond visualizations to explore techniques that reveal how genes and proteins work within microbial communities. In part, that means using next-generation sequencing (NGS), "a powerful tool for examining highly heterogeneous natural microbial communities," the article states.
"Now sequencing isn't the bottle neck," Jansson said of NGS and other technologies that have improved so much in her 30 years of research. "It's interpretation of the data."
But assembling all that data from NGS and elsewhere in meaningful ways is the challenge now, she said. Microbial diversity in soil is especially daunting, and getting good gene assemblies is hard too. But once science has a technique to "bin" entire microbial genomes, said Jansson, it will be a "gamechanger."
Her recent paper with colleagues at PNNL, spelled out in the feature, used a long-lead technique called Moleculo to facilitate a very productive round of genetic binning and gene re-assembly in a sampling of soils from the Kansas prairie.
Jansson and her colleagues also got attention for going beyond metagenomics to integrate that approach with other "omics" techniques. Those include metaproteomics and metabolomics, which another scientist speculated would be where in the near future the microbiome field "sees the greatest technical advances."
By the article's end, Jansson was wishing out loud she could unravel all the metabolic pathways in just one soil-bound microbial community. After all, she added, a better understanding of those pathways could improve predictive models of how climate change will affect the planet's ecosystems.August 2016
PNNLs Vanessa Bailey Helps Pen an Eos Article on a Workshop to Advance Soil Science
Cedar River soil site.
Adding to increased national attention on the importance of soil to Earth's ecosystems, health, and climate, PNNL microbiologist Vanessa Bailey co-authored a meeting report on soil carbon science imperatives that went online Aug. 12 in the journal Eos.
"Advancing Soil Carbon Science" recapped a March 14-16 workshop held in Boulder, Colo. to celebrate the International Decade of Soils (2015-2024), which was declared last December by the International Union of Soil Sciences during a conference in Romania. At the same event, scientists adopted the Vienna Soil Declaration to declare the importance of healthy soils and to set a framework for future research.
Early in the Eos article, Bailey joined co-authors Melanie A. Mayes of Oak Ridge National Laboratory and Kate Lajtha of Oregon State University in laying out the basics: that soils play a vital role in the world's carbon cycle by exchanging carbon with both the Earth's envelope of gases (the atmosphere) and its watery collective of seas, lakes, rivers, groundwater, and even clouds (the hydrosphere).
Moreover, the authors stated, carbon storage in soils helps regulate Earth's climate and determines the productivity of its ecosystems and agriculture. As such, the International Decade of Soils workshop, convened and funded by the 12-agency Carbon Cycle Interagency Working Group, set out to establish a framework for understanding what factors influence soil carbon's resilience and the vulnerability.
Soil carbon vulnerability, for one, heightens when perturbations alter the various forms in which soils store carbon. The result is more leached carbon dioxide and methane, both greenhouse gases.
The workshop had three primary goals: to better understand factors behind soil carbon resilience and vulnerability; to improve predictions of how soils generate climate feedbacks; and to inform what will be the second State of the Carbon Cycle Report, to be published in 2018 by the U.S. Sustained National Climate Assessment.
To that end, the workshop generated three frameworks for action, conceptions which will each later be expanded on and published as forward-looking science: a method for assessing and predicting soil vulnerability; a synthesis of proxies for modeling carbon cycling; and measureable compartments for soil carbon models.
Participants also drafted a survey that will poll soil scientists on how global changes impact soil carbon.
The workshop, held at the University Corporation for Atmospheric Research in Boulder, was co-organized by staffers at Lawrence Berkeley National Laboratory, Argonne National Laboratory, and the U.S. Carbon Cycle Science Program.August 2016
Bailey & Jansson Quoted in PNAS Article
Vanessa L. Bailey and Janet K. Jansson, prominent microbiologists at Pacific Northwest National Laboratory (PNNL), were quoted extensively this week in "Crucial role of belowground biodiversity," a John Carey feature story in the July 12 issue of the prestigious journal Proceedings of the National Academy of Sciences (PNAS).
It was Bailey's description of soil science as a "black box" of mysteries to researchers that was the story's leitmotif. This recurrent image illustrates the huge task ahead for soil scientists, many of whom are doing pioneering soil microbiome work at PNNL.
Bailey, a PNNL Senior Scientist, was quoted as saying that since getting her Ph.D. 17 years ago, "we know more about what's in the black box and what those microorganisms are doing." Gigabytes of new data are emerging from today's studies, now that soil science has moved from the laboratory to the natural world and now that its critical significance to human health and climate change has emerged.
Jannson, Chief Scientist of Biological Sciences at PNNL and director of the Microbiomes in Transition (MinT) initiative, was quoted regarding the many surprises that true soil biodiversity brought to science once genomics and other molecular tools were brought into play. Before, she said, "we had no way of testing what was there. People didn't anticipate there was such a concentration of unknown organisms in soil."
Some of the startling facts of soil biodiversity, according to the story, include that more than 100 billion organisms can live in a handful of soil. And that just one gram of soil, about the weight of a paper clip, can contain enough hyphae (fungal filaments) to stretch out a mile.
Then there is the emerging proof that in surprising ways soils are vital to understanding climate change. Soils, after all, contain an immense percentage of the world's carbon and, when perturbed, could release it into the atmosphere. In the story, climate related research by both Jansson and Bailey got strong mentions.
As the feature pointed out, "much more soil carbon is now poised to churn out into the air as the permafrost melts." As an example of how new genetic and molecular tools are being applied to arctic [cq] soils, the author pointed to Jansson's 2015 paper on the potential climate consequences of warming permafrost. "There is a rapid conversion of this community into one that can release greenhouse gases," she said, referring to bacteria in the subzero soils she studied.
Bailey called soil "the major buffer system for environmental changes" in a statement that earned her a pullout quote. The PNAS feature then gave several column inches of real estate to the 2016 Rattlesnake Mountain soil-switching study she did with PNNL research scientist Ben Bond-Lamberty and others.
Even after 17 years, the paper showed, soil samples subject to the switched locations displayed an apparent lack of climate-change resilience to alterations in moisture and temperature, as measured by bacterial activity. "That was really weird," said Bailey, "and very sobering in the face of planetary change."July 2016
Janet Jansson Among Nine Authors of Nature Review Article
Renowned veteran microbiologist Janet K. Jansson, Chief Scientist of Biological Sciences at Pacific Northwest National Laboratory (PNNL), was among nine authors of a review article in Nature published online July 6.
"Microbiome-wide association studies link dynamic microbial consortia to disease" used 122 papers and drew on authors from seven U.S. research institutions to summarize the latest perspectives. The paper outlines two main points: how much more the scientific community knows about the human microbiome than even the recent past, and how much closer researchers are to linking that microbiome to disease states.
Progress has been accelerated by advances in the research tools used to investigate the microbiome, the authors say, including advances in DNA sequencing, metabolomics, proteomics, and computational methods.
Microbiome-wide disease association studies have shot ahead so fast, they add, particularly because of new multiple molecular perspectives and improved time-series studies. That's an analytical method that collects successive points of data over a period of time, which broadens understanding of a phenomenon.
Some early findings already point to microbiome-disease links that call for action. But there are no clinical applications yet. More frequent observations of the "dynamic interface" are needed, the authors say, along with "an appreciation of the complexity of interactions among the microbiome and the host's diet, chemistry, and health."
The object remains, they say: to develop "precision diagnostics and therapies that are based on the microbiome."
The review article points out how disease has been linked to the microbiome (the genes of our microbes) and to human microbiotas (the microbes themselves, which inhabit an individual's body space). But it also goes into the technical and conceptual pitfalls confronting researchers, especially those pitfalls compounded by studies scaled up to include tens of thousands of people over time.
Microbiome-wide association studies (MWAS), as in the review's title, capture this kind of scale and can help link the microbiome with disease. MWAS is "somewhat analogous" to genome-wide association studies (GWAS), the authors say. But the microbiome contains more genes, and has to take into account a person's individual microbiotas.July 2016
Dick Kouzes Quoted in Science on Helium-3 Shortage
Richard Kouzes was quoted in the July 1 issue of Science.
Pacific Northwest National Laboratory physicist Dr. Richard Kouzes was quoted in the July 1 issue of Science in an article about the efforts to create alternatives to Helium-3 (3He). This rare isotope has unique properties that make it invaluable for applications from cryogenics to detecting hidden nuclear bomb material.
An increased demand for 3He was because of a substantial expansion in its use for neutron detectors in homeland and national security applications, as well as use for neutron scattering science. At the same time, 3He supply was impacted by an unexpected reduction of Russian exports to the marketplace. The demand for 3He by the U.S. Department of Energy's Office of Nuclear Physics alone has been as high as 70,000 liters per year.Kouzes leads research in fundamental and applied nuclear science at PNNL. He was Principal Investigator and Technical Lead for the Lab's largest single project, the Radiation Portal Monitor Project, which resulted in radiation monitors being deployed at all U.S. international borders. At PNNL, Kouzes is a Laboratory Fellow, the highest rank a PNNL scientist or engineer can attain. July 2016

Rasch, a Sailing Scientist, Shares Climate Change Insights
In a recent interview, author Paul Vandevelder tapped Pacific Northwest National Laboratory's Dr. Philip Rasch for his expertise in climate science—his passion for sailing is a bonus.
Cruising World is a resource for sailboat enthusiasts. In his article The Climate Conundrum, Vandevelder says, "A new term in the sailor's glossary, climate change, is going to be a factor in all things sailing for the rest of our lives and beyond."
Rasch explains the interaction between weather patterns on land and the effects on oceans. He also talks about how oceans carry heat from the equator to the polar regions.
"Tropical cyclones and hurricanes are going to get stronger. In the overall pattern, wet places are going to get wetter, and the dry places drier," Rasch said.
Rasch is chief scientist for climate and a laboratory fellow.June 2016
PNNL Climate Scientist Chand Consulted for ClimateWire Story
ClimateWire's article "Do clouds + smoke = climate change? Africa may have answers" explores how a farmer burning his fields in Africa might contribute to cooling the planet. It considers a $1 million study-funded by NASA and the Department of Energy—which is the first of its kind in the Southern Hemisphere.
The story consults Pacific Northwest National Laboratory's Dr. Duli Chand, atmospheric scientist, for his expertise in atmospheric measurement and data sciences. Chand explains that a satellite launched in 2006 shows where the aerosol particles are located, but not the micro-detail of the particles.
"If the satellite is perfect, I'd prefer to use the satellite observations. But unfortunately, they are not perfect and complete, so we have to rely on aerial observations," Chand told ClimateWire.June 2016

Dr. Ghassem Asrar, often sought out for his technical expertise, was interviewed by the Huffington Post for an article in a recent blog post. Asrar is the director of the Joint Global Change Research Institute, a partnership between Pacific Northwest National Laboratory and the University of Maryland. His pre-PNNL portfolio is impressive with appointments to World Climate Research Program (WCRP) and U.S. National Aeronautics and Space Administration (NASA).
The recent Huffington Post blog takes readers on a journey from his childhood in Iran to his recent acceptance of an Exceptional Performance Award from NASA. The goal of the interview is "harnessing the untapped potential of Iranian-Americans, and building the capacity of the Iranian diaspora in effecting positive change in the U.S. and around the world."
Asrar's research interests are grounded in:
- Earth system science research and education
- Multi-spectral remote sensing of Earth's biosphere and atmosphere
- Modeling mass, energy and the transfer of heat energy (radiation exchange) between Earth's surface and atmosphere
Morris Bullock Quoted in Chemical & Engineering News
Morris Bullock was quoted in the June 13, 2016, issue of Chemical and Engineering News.
In the June 13 issue of Chemical & Engineering News, Dr. Morris Bullock at Pacific Northwest National laboratory is quoted as an outside expert. In the article titled "Chemists announce the end of the innocence for cyclopentadienyl," writer Stephen K. Ritter covers research by two groups that show the ligand cyclopentadienyl is reactive, suggesting new opportunities for catalyst design. Bullock is quoted at the end of the article about the significance of the research.
At the national laboratory, Bullock leads the Center for Molecular Electrocatalysis, an Energy Frontier Research Center funded by the U.S. Department of Energy's Office of Science.

Teeguarden behind EPA panel on new framework for Exposure Science
Toxicologist Justin Teeguarden, a scientist in PNNL’s Health Impacts and Exposure Science organization and Director of the Oregon State University-PNNL Superfund Research Center’s Research Translation Core, helped organize and lead a May 9-11 expert workshop hosted by the Environmental Protection Agency (EPA). Under discussion was the new systems-based “Aggregate Exposure Pathway” (AEP) concept proposed by Teeguarden and his colleagues, in response to a call by a committee of the National Research Council for an organizing framework for the field of Exposure Science.
The workshop brought together scientists from the fields of toxicology, exposure science, modeling, epidemiology, and risk assessment from academia, industry, regulatory agencies, and non-governmental organizations. Attendees advanced the AEP concept in three working groups focused on high impact application areas, the infrastructure to support implementation, and ecological exposure assessment.
Teeguarden's involvement in the Research Triangle Park, NC workshop followed his May 2016 paper in Environmental Science & Technology: "Completing the Link between Exposure Science and Toxicology for Improved Environmental Health Decision Making: The Aggregate Exposure Pathway Framework." Researchers from the EPA and Oregon State University also contributed.
Exposure science, the paper averred, is changing fast, and is transitioning "from a field of observation to a field of prediction." The AEP framework is a step in that evolution, the authors wrote, and is a systems-based response to "major scientific advances in analytical methods, biomonitoring, computation, and a newly articulated vision for a greater impact in public health."
The paper and the workshop reflect a growing scientific leadership role for PNNL in the field of exposure science.June 2016
PNNL Researcher Ben Kravitz's Opinion Sought on 'Far Out' Climate Solutions
Some geoengineering scientists are thinking of big—out-of-this-world sized—solutions to cool our warming planet. The BBC article How a giant space umbrella could stop global warming wonders if the answer might be to create a man-made structure between us and the Sun to cast a shadow on our planet.
They asked Dr. Ben Kravitz for his opinion.
Kravitz was consulted as an outside source because of his expertise in the field. As a researcher at Pacific Northwest National Laboratory, Kravitz's primary method of investigating how the climate system works is through simulations of geoengineering—or deliberate interventions into the climate system to counteract some of the effects of human-induced climate change. He also is the coordinator of the Geoengineering Model Intercomparison Project (GeoMIP), a worldwide effort to understand common climate model responses to various geoengineering scenarios.
"There's still a lot of work to do before we understand what geoengineering can and cannot do," Kravitz told the BBC.May 2016
Thallapally's Metal-Organic-Composites Research Featured in MRS Bulletin
Dr. Praveen Thallapally
Dr. Praveen Thallapally’s research on a novel, oxygen-separating metal-organic-framework (MOF) was featured in the Material Research Society’s MRS Bulletin in April 2016. Thallapally and his Pacific Northwest National Laboratory (PNNL) team discovered how to separate oxygen from other gases simply and cheaply, as first reported in Advanced Materials. They developed a composite of MOFs with a helper molecule to separate oxygen from other gases. Practical applications for the discovery could range broadly from removing oxygen for food storage to making pure oxygen for fuel cells.May 2016
Bailey, Bond-Lamberty, Jansson in Yale Environment 360
Vanessa Bailey checking on soil samples in 2008, during a nearly two-decade-long analysis of microbial activity in soil.
A study led by Dr. Vanessa Bailey and Dr. Ben Bond-Lamberty of Pacific Northwest National Laboratory (PNNL) took center stage in "Is Climate Change Putting the World's Microbiomes at Risk?," a March 28 article in the online magazine Yale Environment 360.
In the study, which appeared in PLoS One (see research highlight), researchers had a rare long-term look at soil responses over 17 year to changes in temperature, moisture, and other factors. They transplanted dryland soil-core samples from a moist, cool, higher-elevation site to a lower, drier site (and vice versa) and found that microbial communities and carbon-transfer characteristics in the soils had adapted very little to the new climate conditions.
In what may become, in part, a rapidly warming and drying world, this is no good news, said Bailey. "Soil is the major buffer for environmental changes, and the microbial community is the basis for that resilience." Climate change, the article added, will affect in unknown ways the "planetary microbiome in the Earth's crust and water," the quadrillions of microorganisms that "run the world."
PNNL researchers are at work unraveling what role microbes in soil play in the ecological machinery of Earth. The tiny, teeming, and cooperative fungi, archaea, and bacteria in soils represent one-third of Earth's biodiversity. They also store up vast quantities of CO2 and other greenhouse gases, and (once they are understood more) may one day improve climate models.
Also quoted was Dr. Janet Jansson, chief scientist for the Earth and Biological Sciences Directorate at PNNL and president of the International Society for Microbial Ecology. She is initiative lead for PNNL's Microbiomes in Transition, which investigates how climate change and pollution affect microbiomes.April 2016

Climate Scientist Rasch is Expert for Michigan Engineering Article
Help with understanding geoengineering
Dr. Philip Rasch, Chief Scientist in climate science at Pacific Northwest National Laboratory, was quoted in an in-depth article from Michigan Engineering, "Is it Time to Get Serious About Geoengineering?"
The article describes the sometimes controversial topic of geoengineering. It's a concept that involves what many believe are last-ditch efforts to reduce the climate effects of greenhouse gases only while long-term mitigation is in progress.
The article describes geoengineering as an area of science many avoid for fear of showing recognition of human-caused climate change significance.
"We would all like to believe that we're not harming the planet," said Rasch. "And any time you consider something like geoengineering it's an explicit recognition that we've reached a point where we need to be really worried."
As an internationally recognized scientist in climate modeling with emphasis on the climate impact of aerosols and clouds, Rasch's expertise makes him one of few to use innovative analysis studies to provide insight into the impacts and consequences of geoengineering techniques.
Rasch and his climate modeling colleagues are optimistic their expertise will provide a fundamental and useful understanding of Earth's climate system. "We don't have a lot of time to mess around," he said. "Because some of the changes we're anticipating will at some point become irreversible."March 2016
Praveen Thallapally's Research on MOFs Featured in Materials Today
Dr. Praveen Thallapally's research on a new metal-organic framework, or MOF, that separates oxygen was featured by Materials Today in March 2016. Thallapally and his colleagues at Pacific Northwest National Laboratory created the material -- a composite of a MOF and a helper molecule where the two work in concert - that separates oxygen from other gases simply and cheaply. The results, reported in Advanced Materials, might help with making pure oxygen for fuel cells, using that oxygen in a fuel cell, and removing oxygen in food packaging, among other uses.March 2016
Susannah Burrows' Biogenic Research Featured in Earth Magazine
Dr. Susannah Burrows, atmospheric scientist at Pacific Northwest National Laboratory, authored a study published in the journal Science Advances, together with the University of Washington, and was featured in the November 2015 issue of Earth Magazine. The Earth article, "Marine Microorganisms Drive Summer Clouds Over Southern Ocean," highlights the finding that gases and particles originating from phytoplankton, microorganisms that live in the sea, are responsible for up to half of the droplets that produce clouds over the Southern Ocean during the summer months.
Burrows' research is focused on how tiny particles called aerosols interact with clouds to affect climate. Her expertise in atmospheric diagnostics and modeling is frequently called upon to study aerosols, especially those resulting from material produced by marine organisms.
Researchers are continually working to include adequate measurements to better inform the climate models. Studies such as Burrows' highlight how previously overlooked contributors may affect the climate. These measurements will be vital for informing climate models to improve that understanding.March 2016
Hailong Wang's Soot-in-Snowpack Research Highlighted in NPR Story
Dr. Hailong Wang described the sources and consequences of soot falling on snowpack in the Pacific Northwest and around the world for a story that aired on Northwest News Network public radio stations. The soot, a result of incomplete combustion, is coming from sources such as vehicle pollution, carbon-fueled power plants, and forest fires. Because the soot absorbs sunlight, it warms just enough to cause increased snow melting. This can be a problem in regions that rely on mountain snow melt for seasonal water supplies to fill reservoirs and crop irrigation systems.
Wang led research to improve climate models accounting for soot falling on snowpack. Better models will help those who need to understand changes in seasonal fresh water supplies in a warming climate.
Wang, a PNNL researcher since 2009, got his Ph.D. in atmospheric sciences from the University of Illinois at Urbana-Champaign. Recently, his research has focused on developing a source-tagging technique in the Community Earth System Model, to understand the relationship between global sources of soot and its impact on snowpack and glaciers at various locations around the world.February 2016
Bond-Lamberty Provides Carbon Storage Insight for The Washington Post
Reporting on a recent study about terrestrial carbon storage, The Washington Post quoted Dr. Ben Bond-Lamberty about the change in tropical nighttime temperatures that may play a big role in the global carbon cycle balance under the pressures of climate change.
"Daytime temperatures, we're going to expect, will affect both sides of the carbon uptake and loss equation-the photosynthesis uptake side and then the respiration loss side-whereas changes in nighttime temperature are just going to affect the respiration side," he said. "I would say, sort of a priori-and there have been a couple of previous papers on this subject-you would expect that the nighttime temperatures would exert an unbalanced effect."
Bond-Lamberty, a PNNL researcher working at PNNL's Joint Global Change Research Institute (JGCRI) in College Park, Maryland since 2009, got his Ph.D. at the University of Wisconsin, Madison. He is a section editor for PLOS ONE, and on the editorial boards of Global Change Biology and Plant and Soil. The JGCRI is a partnership between PNNL and the University of Maryland.February 2016
Samson Hagos Research Featured in Climate Central Post
Dr. Samson Hagos was quoted in a posting by Climate Central, a respected online site where scientists research climate science and journalists report the impacts of climate change on Americans. In a post authored by John Upton, Hagos' most recent published work was used as the basis of the article "West Likely to Be Stormier With Climate Change."
Hagos led research that showed the effects of climate change on atmospheric rivers that carry lots of water from the tropical Pacific Ocean, eventually dumped on the West Coast during winter. The increase of the frequency and severity of these storms threatens more devastating floods in the U.S. West. The research projects an increase in extreme rain events due to atmospheric rivers by century's end under the influence of climate warming.
Hagos, a PNNL researcher since 2008, got his Ph.D. in atmospheric science from Cornell University. His research investigates the variability of precipitation at a wide range of spatio-temporal scales that span individual storm systems, the Madden-Julian Oscillation, atmospheric rivers and regional monsoons as well as their responses to climate change.February 2016
Marquez Floats Ideas about Underwater Data Centers in IEEE Spectrum
In a discussion about Microsoft’s Project Natick, where the computing giant is examining the viability of underwater data centers, Andres Marquez, a research scientist and Advanced Architectures Team Leader in the Advanced Computing, Mathematics, and Data Division’s High Performance Computing group, spoke to IEEE Spectrum about how these undersea facilities could “play an important role in meeting the world’s growing demand for Internet services.” He also touched on how the salty ocean presents other problems when it comes to protecting data servers over time.

Kravitz Provides Geoengineering Insight for Slate
When the e-zine Slate needed expertise to explain geoengineering and climate modeling for a recent article, they turned to Dr. Ben Kravitz, atmospheric scientist and climate modeler at Pacific Northwest National Laboratory.
The Slate article, How Geoengineering Could Affect the Global Climate, covered ideas explored in the Geoengineering Model Intercomparison Project, something Kravitz knows very well. As a lead scientist organizing and designing experiments for the project, he is in a unique position to provide insight. The question-and-answer format of the article provides many details about modeling geoengineering questions. The Slate article is part of "Futurography," a series introducing readers to "the technologies that will define tomorrow."
Kravitz, a PNNL researcher since 2013, got his Ph.D. at Rutgers University in 2011. He is a recipient of the International Union of Geodesy and Geophysics Early Career Scientist Award.February 2016
Gokul Iyer Quoted in News Outlets on Emission Reduction
Dr. Gokul Iyer, researcher at the Joint Global Change Research Institute, a collaboration between Pacific Northwest National Laboratory and the University of Maryland, was quoted in several outlets regarding a paper published in Science. The publication Can Paris Pledges Avert Severe Climate Change? was co-authored by Iyer and colleagues including PNNL researchers Leon Clarke, Jae Edmonds, Haewon McJeon, and Ghassem Asrar.
“Real success depends on a robust process that allows pledges to be progressively tightened over time. If countries ramp up efforts beyond 2030, we'll have a much better chance of avoiding extreme warming and keeping temperature change below 2 degrees Celsius,” said Iyer, as quoted in Huffington Post.
The research attracted media attention as its timely publication focused on climate change research just days before world leaders of 190 countries gathered in Paris to discuss pledges to reduce emissions through the year 2030. The study in Science compared the Paris commitments to a world where countries take no action, or where they begin to reduce emissions only after 2030. They found that if successfully implemented and followed by additional, post-2030 measures of equal or greater ambition, the pledges are a stepping stone for reducing the probabilities of the worst levels of climate change and limiting global warming to 2°C.January 2016
Leon Clarke Quoted in Nature
Dr. Leon Clarke, integrated assessment modeling researcher at Pacific Northwest National Laboratory, was quoted in the article "Is the 2°C world a fantasy?" The article, published by the journal Nature, discusses the different scenarios for limiting global warming and the efforts society would need to take for this to be possible.
Clarke conducts his research at the Joint Global Change Research Institute (JGCRI), a partnership between PNNL and the University of Maryland, and was recently honored by the Integrated Assessment Modeling Consortium (IAMC) for his prominent contributions to the integrated assessment modeling community.
Clarke received his Ph.D. in Engineering-Economic Systems and Operations Research from Stanford University. His research at PNNL tackles issues related to energy, technology, policy, and climate change.January 2016

Top-10 Paper Co-Authored by PNNL's Ben Bond-Lamberty
Dr. Ben Bond-Lamberty taking samples in the field.
Cover of the journal Biogeosciences
An influential paper co-authored by Pacific Northwest National Laboratory scientist Dr. Ben Bond-Lamberty was recently listed as one of the 10 most-cited papers from Biogeosciences in 2014. Published in 2012, the paper finds that scientists haven't yet come to a conclusion on what happens when soil freezes or gets very dry.
The study reviewed 50 years of literature and found that there is a wide range of results when soil is dried and then rewetted, or frozen and then thawed. The paper received attention because of its comprehensive review, as well as its recommendations to address the current gaps in knowledge. Learning more about what happens when soils are rewetted or thawed is important because transitions like those will be happening more often in parts of the world experiencing climate changes. Current models don't simulate such dry-to-wet or cold-to-warm changes very well.
Bond-Lamberty is a research scientist at the Joint Global Change Research Institute, a partnership between PNNL and the University of Maryland. He received a Ph.D. in Forest Ecosystems Ecology from the University of Wisconsin, Madison.

Hagos MJO Paper Featured in Eos
Dr. Samson Hagos, atmospheric researcher at Pacific Northwest National Laboratory, authored a paper published in the Journal of Geophysical Researcher - Atmospheres which was then chosen as a research spotlight in the American Geophysical Union's Eos Earth & Space Science News weekly newsletter. "Researchers Roll Clouds into Climate Modeling" appeared in the April 2015 newsletter as a summary of how scientists can now explicitly simulate cloud systems in regional and global climate models instead of parameterizing them.
On comparing model simulations that included clouds with what played out in reality during observations as part of the ARM Madden-Julian Oscillation (MJO) Investigation Experiment/Dynamics of the Madden-Julian Oscillation Experiment (AMIE/DYNAMO) field campaigns, the team found factors as small as raindrop physics may affect the accuracy of these state-of-the-art models.
"Our study highlights the utility of using observations to evaluate how well the next generation of climate models, called cloud-permitting models, can directly capture the behavior of clouds," said Hagos. "While these newer models have not yet completely overcome several challenges, they do capture some processes fairly well. For example the relationship between cloud size and depth, which is an important feature of organization of tropical clouds, is well reproduced by the model simulations."
Hagos is a recognized leader in tropical cloud dynamics and regional climate modeling. His research interests are focused on the understanding and modeling of precipitation processes over a wide range of spatio-temporal scales, from the lifecycles of individual convective cells, intraseasonal oscillations and monsoons to their responses to global climate change.
Hagos earned his Ph.D. in atmospheric sciences in 2008 from Cornell University, and was a Postdoctoral Research Associate at the Rosenstiel School of Marine and Atmospheric Sciences of University of Miami before joining PNNL in 2009.

Yang Gao Invited Blog Author for Earth Day at Weather Underground
Dr. Yang Gao, atmospheric postdoctoral researcher at Pacific Northwest National Laboratory, was invited to write a community member blog for the Weather Underground's Earth Day events. "Riding the cold weather rollercoaster" explains recent research that indicates extreme cold events, called "cold air outbreaks" will continue over North America, though less frequently, despite global warming trends.
Gao and his PNNL team, Drs. Ruby Leung and Jian Lu, and collaborators from Giacomo Masato and the University of Reading, UK, found that a large swath over North America will still experience the top five coldest historical events, even with global climate warming. These cold snaps can be more deadly than heat waves, with large human and economic costs.
The research analyzed climate forces that allow extreme cold events to persist over the region, even as the climate warms. Understanding these trends and projections will be vital to communities that, while adapting to warmer average temperatures, will still have to be prepared for extreme cold events.
Gao has expertise in global and regional climate modeling, especially extreme weather events. He has undergraduate degrees in environmental engineering from universities in China, and a Ph.D. in civil engineering from the University of Tennessee.April 2015
Janet Jansson Featured on NPR's Science Friday
Dr. Janet Jansson at Pacific Northwest National Laboratory spoke with Ira Flatow on National Public Radio's Science Friday on April 10, 2015, about how permafrost thaw is changing our environment. As temperatures warm, microbes in the permafrost become more active and decompose carbon in the permafrost soil. The permafrost has a large reservoir of carbon available, about twice as much as resides in the atmosphere. In worst-case scenarios, climate change could lead the microbes to release large amounts of methane and carbon dioxide into the atmosphere. Understanding the impacts of climate change on biological systems is a key part of Jansson's research.April 2015
Kravitz Talks Geoengineering with Grist
Dr. Ben Kravitz, a climate researcher specializing in geoengineering studies at Pacific Northwest National Laboratory, was contacted by Grist - an online source of environmental news and commentary for his insight about climate change. The article, "Why we should talk about geoengineering even if we never do it," quoted Kravitz about some concerns that geoengineering could be used to offset the warming of the climate. "Modeling studies of geoengineering have allowed us to ask questions about how the climate system works that we didn't even know we wanted to ask," said Kravitz. "It's actually in some ways changed the way I think about problems in climate science."
With his Rutgers University Ph.D. mentor Alan Robock, Kravitz began an international collaboration called the Geoengineering Model Intercomparison Project. The GeoMIP successfully compares identical geoengineering simulations on climate models today. "My experience is that by talking about geoengineering, I get more people interested in talking about climate change, which I think is a much bigger issue." Kravitz is also hosting a weeklong summer school for early-career scientists interested in climate change.
Geoengineering, sometimes called solar radiation management, is the deliberate reduction in the amount of solar radiation retained by the Earth as a proposed temporary method to reduce some of the effects of greenhouse gases while mitigation is in progress.March 2015
Climate Change Authority Steven J. Smith Quoted in The New York Times
Pacific Northwest National Laboratory scientist Dr. Steven J. Smith was quoted in The New York Times online edition article about a recent International Energy Agency report. The preliminary report indicates that efforts to increase energy efficiency and reduce carbon dioxide emissions may be paying off.
However, several experts, including Smith, indicate caution in interpreting short-term numbers. "We need to be cautious about the meaning of data from any one year," said Smith. "What is important is the long-term trend. We need to understand if the fundamental forces that drive energy and emissions have changed."
Smith, a recognized international expert in global emissions and climate mitigation, works at PNNL's Joint Global Change Research Institute, a partnership with the University of Maryland, located in College Park.

Steven J. Smith Quoted in Climate Central, Scientific American, The Guardian, NBC News
Dr. Steven J. Smith of Pacific Northwest National Laboratory was quoted in several outlets regarding a paper published in the journal Nature Climate Change. The publication "Near-term Acceleration in the Rate of Temperature Change" was co-authored by PNNL researchers Jae Edmonds, Corrine Hartin, Anupriya Mundra, and Kate Calvin.
"Essentially the world is entering a new regime where what is normal is going to continue to change and it's changing at a rate that natural processes might not be able to keep up with," said Smith, as quoted in Climate Central and Scientific American.
The research attracted media attention as one that focused on the critical issue of the rate at which the climate is warming. While other studies have focused on climate over a 100-year perspective, the PNNL study looked at 40-year periods, a time interval important for infrastructure and systems planners.
"We focused on changes over 40-year periods, which is similar to the lifetime of houses and human-built infrastructure such as buildings and roads," said Smith. "In the near term, we're going to have to adapt to these changes."
The researchers work at PNNL's Joint Global Change Research Institute, a partnership with the University of Maryland, located in College Park.March 2015
Burrows Quoted in Scientific American on Youth Science Competition
Dr. Susannah Burrows, an atmospheric postdoc researcher at Pacific Northwest National Laboratory, discussed her experience as Science Olympiad alumna and volunteer at the 2015 MIT Invitational in a blog post by Scientific American's Amanda Baker. The article highlights youth science competitions that aim to examine their performance when faced with real scientific research challenges. As an alumna, Burrows expressed the importance of partnership and teamwork in these competitions. Teamwork, such has this, has left a lasting impression throughout her career.
"Science Olympiad is a great way for students to engage with different science topics and at a deeper level than they might in the classroom," said Burrows. "Being part of a team makes the science competition a lot more attractive and fun for many students than competing on an individual basis. Many people think of science as a solitary pursuit, but teamwork is more reflective of how most scientists actually work."
Burrows is a climate modeler whose research explores chemical modeling of marine biogeochemical influence on submicron sea spray particles.February 2015
Rasch Quoted in Tri-City Herald on Cooling Planet Ideas
Dr. Philip Rasch, atmospheric scientist at Pacific Northwest National Laboratory, was quoted in the February 10, 2015 issue of Tri-City Herald on the hot topic - cooling the planet. The article, "Fed Report with PNNL Input: Time to examine purposely cooling planet idea," discuses one idea in particular: to purposely intervene in the planet's climate as a last ditch effort to counter global warming effects.
Using such an artificial shield over the Earth, similar to a cloud, but made of small particles, could be a relatively cheap, effective and quick way to cool the planet by mimicking the natural effects on climate of large volcanic eruptions. But scientists concede there could be dramatic and potentially dangerous side effects that they don't know about.
Rasch, a panelist for the first-of-its-kind National Academy of Sciences discussion on these ideas, was quoted in the article to say that the strategy may be useful to society in the future. "There are many issues associated with climate intervention that are currently poorly understood, and research would help. I'd rather know more than less if we ever need to decide whether to try it," said Rasch.
According to Rasch, the research could also advance knowledge of the way climate processes work, creating a better understanding of the basic physics and chemistry that affect Earth. The government-associated panel said that research in the field would benefit from some kind of governance or other oversight before it is done.February 2015
Ben Kravitz Quoted in New York Times Op Talk
Dr. Ben Kravitz, atmospheric scientist at Pacific Northwest National Laboratory, was quoted in a February 20 New York Times Op Talk blog. Kravitz is known for his research on atmospheric particles, also known as aerosols, and the way they change how the Earth reflects or absorbs sunlight. The blog explored the idea that a purposeful injection of tiny particles into the atmosphere to reflect sunlight away from the Earth might also alter the night sky, blocking the view of stars. Kravitz stated that the whitening effect of aerosol injections "would be similar to the whiter sky that is often seen in large cities or areas with industrial pollution." Geoengineering is another term for "albedo modification," a theoretical method that could make the Earth more reflective to temporarily alleviate some of the climate warming effects of greenhouse gases.

Shaw is a project manager for the PNNL work to develop and deploy the instruments, sponsored by the Department of Energy.December 2014
Will Shaw Quoted in Wired on Measuring Wind
Dr. William Shaw, atmospheric scientist at Pacific Northwest National Laboratory, was quoted in November's online Wired article, "Scientists Are Going to Shoot Lasers Into the Sky to Measure the Wind." The article describes the new ocean-going buoys that PNNL is operating for the U.S. Department of Energy to measure how much energy really is in the wind offshore. The measurements will also help engineers determine just how much wind force the turbines need to withstand. To get previously unavailable wind measurements, the team of scientists will measure offshore winds up to 200 meters above the ocean surface beginning in mid-November off the coast of Virginia. Using upward-facing lidar instruments attached to the buoys, they will learn more about how wind behaves offshore, which in turn will help turbine designers produce larger, more efficient turbines. The buoys will be periodically moved to provide new wind measurements at numerous locations along the coasts.

Ben Kravitz Quoted in IOP News Blog for Geoengineering Work on Climate Change
Dr. Ben Kravitz, a postdoctoral researcher in atmospheric sciences at Pacific Northwest National Laboratory, was quoted in environmentalresearchweb, the IOP community website on his recent solar geoengineering paper. Discussing the publication in Environmental Research Letter, "A multi-model assessment of regional climate disparities caused by solar geoengineering," the article quoted lead author Kravitz on the concerns of solar geoengineering used to offset the warming of the climate and some examples of the tradeoffs that could arise across different regions. The takeaway: solar geoengineering alone is not the answer to slowing climate warming, but depending on the regional needs geoengineering can offset some of the effects. "If society continues to increase carbon dioxide emissions and offsets the climate change with geoengineering, we would need to do continually more geoengineering to keep up with increasing emissions," said Kravitz.

Yoon Quoted Nationwide on Melting Sea Ice
Jin-Ho Yoon, climate physics scientist at Pacific Northwest National Laboratory, was quoted in more than 250 outlets nationwide regarding a recent publication on how shrinking sea ice contributes to a weakening polar vortex, which can be potentially linked to cold weather in the United States or other parts of the world. The article, "Study Links Polar Vortex Chills to Melting Sea Ice," ran in outlets ranging from the local Herald to The Associated Press. Yoon also is co-author of the publication, "Weakening of the Stratospheric Polar Vortex by Arctic Sea-ice Loss," appearing in September's issue of Nature Communications. In the article, Yoon and his co-authors describe the polar vortex, which usually stays in the Arctic, wandering south from time to time, but recently has moved more southward, as being disturbed by the sea ice loss over the Kara-Barents Sea region. When there is less ice, more energy can move from the relatively warm ocean surface to the atmosphere and disturb the polar vortex. Although this mechanism is newly identified, there are other processes that potentially compete or work simultaneously to cause the polar vortex to weaken, creating cold air outbreaks.September 2014
