The way hydrocarbon molecules interact with light can affect the production of nitrous acid in the atmosphere. In this study, researchers used an ultrafast electron camera to image the motions of hydrocarbon molecules at ultrafast, ultrasmall scales. They identified a proton transfer step followed by an out-of-plane twisting motion as key components of energy relaxation after molecules interact with light.

Members of the American Meteorological Society (AMS) have elected Alan Sealls to the position of AMS president-elect for 2025, as well as electing six new members of the AMS Council: Stephen B. Bennett, Danielle A. Breezy, Jenny Frankel-Reed, Stephanie C. Herring, John M. Lanicci, and Russ A. Schumacher. 

Hail is the result of raindrops being propelled into the coldest parts of the atmosphere. Eventually, stones fall back to Earth, where scientist have been studying for decades how they form. Now, with the help of CT scans, researchers could see the insides of the icy stones without breaking them for the first time. This way they have observed the entire internal structure of exceptionally large hailstones, which might provide important information about future extreme hail events.

WASHINGTON — The U.S. Naval Research Laboratory (NRL) will feature advanced technologies and research ranging from Earth to space sciences during the 24th Annual American Geophysical Union (AGU) Conference at the Walter E. Washington Convention Center in Washington, D.C., Dec. 9-13.
