Wildfires are becoming a bigger focus for scientists that study air pollution, said Nga Lee (Sally) Ng, professor in the School of Earth and Atmospheric Sciences. Ng is also the principal investigator of ASCENT, a new federally funded, national monitoring network that began last year to measure a wide range of air pollutants in real time. The readings from the Los Angeles area fires were captured at the network’s monitoring station in Pico Rivera, several miles from the active fires.

Language models have become an essential part of the burgeoning field of artificial intelligence (AI) psychology. In an article published in Nature Human Behaviour, School of Psychology Assistant Professor Anna Ivanova discusses 14 methodological considerations that can be used to design more robust, generalizable studies that evaluate the cognitive abilities of language-based AI systems, as well as to accurately interpret the results of these studies.

In this piece, Zachary Handlos, senior academic professional in the School of Earth and Atmospheric Sciences, explains the work of climatologists, stating that “climatologists can take on a lot of roles. It’s important to understand the difference between weather and climate. So weather is the study of what's going on in the atmosphere right now. Climatology looks at data for a certain day and compares it to what’s called a climate normal. What this means is, they take a 30-year period of data for that day, and from that baseline, say, ‘Oh, the temperature today is above average or below average.'”

The Genomic Enumeration of Antibiotic Resistance in Space (GEARS) experiment, managed by NASA's Ames Research Center in California's Silicon Valley, is designed to analyze microbial resistance in space. As part of the study, astronauts collect samples from interior surfaces aboard the ISS to detect antibiotic-resistant bacteria, particularly Enterococcus faecalis, a microorganism naturally found in the human body. This initiative marks the initial phase of broader research on microbial behavior in space and its implications for medicine on Earth.

"Enterococcus is an ancient organism that has coexisted with humans since our evolutionary origins," explained Christopher Carr, co-principal investigator of GEARS and assistant professor in the School of Earth and Atmospheric Sciences and the School of Aerospace Engineering. "It thrives inside and outside its host, contributing to its status as the second leading cause of hospital-acquired infections. Our goal is to understand how this microbe adapts to space conditions."

GEARS aims to refine methods for detecting and identifying resistant bacteria, expanding upon ongoing microbial monitoring efforts aboard the ISS.

Mustard gas, or sulfur mustard, is one of the most harmful chemical warfare agents, causing severe blistering of the skin and mucous membranes upon contact. To enhance battlefield detection of this hazardous substance, a team of chemists, including M.G. Finn, professor in the School of Chemistry and Biochemistry and the School of Biological Sciences, will develop a streamlined method for detecting vesicants—a broader class of chemical agents that includes sulfur mustard.

“We will initially focus on model compounds that act like mustards, but that can be handled safely in the laboratory. This will allow us to test different molecular sensor designs, with Professor Jennifer Heemstra's lab and ours working together on complementary approaches,” Finn explains.
