Digging into Clouds from the Bottom Up
Researchers created new code commands to compute the cloud droplet number concentration using existing surface measurements

Scientists at PNNL got creative with the data they already have to calculate a cloud property normally acquired by research aircraft flying through it. What is this valuable measurement they seek? The cloud droplet number concentration provides insight into how reflective and long-lasting a cloud is, to understand the amount of sunlight energy that hits Earth's surface.

Invited Reviews Showcase Analytical Research by Two Early Career Scientists

Congratulations to Dr. Grant Johnson and Dr. Patrick El-Khoury at Pacific Northwest National Laboratory on being invited to write articles for the emerging investigator issue of Analyst, published by the Royal Society of Chemistry. They joined 47 other early career researchers in sharing the analytical techniques they've devised to make discoveries about the world around us. Their articles appear in the journal's June 21 issue.

A Slow Separation
Novel model illustrates the finer details of nuclear fission

In the first study of its kind, scientists collaborating from the University of Washington, Warsaw University of Technology, Los Alamos National Laboratory and PNNL developed a novel model seeking a more intricate look at what happens during the final stages of the nuclear fission process. Using the model, they determined that fission fragments remain connected far longer than expected before the daughter nuclei split apart, delivering a long-awaited description of real-time fission dynamics within a microscopic framework and opening a pathway to a theoretical method with abundant predictive power. Notably, in addition to its publication, the paper was highlighted as an Editors’ Suggestion by Physical Review Letters.
