Like a toxic Trojan horse, microplastics can act as hot pockets of contaminant transport. But, can microplastics get into plant cells? Recent research shows that they can't.

Miscanthus and switchgrass are promising alternatives to traditional annual crops.

A new study provides insights on the location of forcing that yields the optimal cooling effect.

New research improves chemical understanding of how ultrafine atmospheric particles grow into climatically active sizes.

A zoonotic coronavirus known as SADS-CoV that has killed many pigs has the ability to infect human cells, surprising scientists.

PNNL researchers evaluated the accuracy of their software system designed to track bird and bat behavior around remote offshore wind turbines.

The MIT-sponsored competition encourages community approaches to developing new solutions for analyzing graphs and sparse data; PNNL has placed a winner in each year.

In a new video series, PNNL is highlighting six scientific and technical experts in the national security domain throughout the fall. Each was promoted to scientist and engineer level 5 earlier this year.

Community Land Model 5.0 can represent how irrigation influences water, carbon, and nitrogen budgets throughout a highly managed semiarid watershed.

PNNL researchers are contributing expertise and hydrothermal liquefaction technology to a project that intercepts harmful algal blooms from water, treats the water, and concentrates algae for transformation to biocrude.

Aerosol treatments in E3SM affect clouds, heat reflected to space, and Earth’s snow-or-ice-covered surface.

A perspective article in the Journal of the American Chemical Society by a team of PNNL researchers shows the way forward to understand ammonia oxidation.

Brian Milbrath, a physicist in PNNL’s National Security Directorate, was named a senior member of the Institute of Electrical and Electronics Engineers (IEEE).

Ocean engineer Molly Grear leads Triton Field Trials research studying methods to detect electromagnetic fields associated with marine energy devices.

A PNNL engineering team has designed personal protective equipment in support of COVID-19 aid.

PNNL researchers developed two web-based tools to assess and mitigate cyberthreats to utilities—inside and outside their firewalls. Both are low cost and can be used by control room operators who are not cybersecurity experts.

Researchers created an open database for soil-atmosphere greenhouse gas flux data.

Emulators—algorithms that fill data gaps—are traditionally used to project average temperatures and precipitation. This work shows that efficient emulators can substitute for costly simulations over a wide range of extreme indices.

An award-winning ion separation technology developed at PNNL has been licensed for biomedical applications. Continued research aims to make the devices suitable for molecular analysis in the field.  

Soil microbial communities produced more water retaining molecules when enriched with insoluble organic carbon, chitin, compared to a soluble carbon source, N-acetylglucosamine.
