Precision measurement of polarization

Allison Zec has achieved the world record in precise measurement of an electron beam’s polarization, measuring it to within half a percent. Her work on the CREX Compton polarimeter was recognized with the prestigious JSA Thesis Prize, awarded by the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility.

A novel drug screen identifies potential new therapy to lower bad cholesterol levels

Researchers at the Medical University of South Carolina have identified a novel class of compounds that effectively lower cholesterol, triglycerides and apoB in human liver-like cells. These molecules work independently of the LDLR pathway and offer a new treatment regimen for patients with familial hypercholesterolemia.

Hardship affects the gut microbiome across generations

Research found that mothers' childhood experiences and pregnancy anxiety are reflected in their 2-year-old children's gut microbiomes, with smaller populations of microorganisms and reduced genetic diversity. These changes may influence children's socioemotional development and brain-gut microbiome connection.

Reducing food waste is a smaller environmental win

A new University of Colorado Boulder study finds that reducing food loss and waste could lead to increased access to affordable food worldwide, but at the cost of reduced environmental benefits. The study suggests that more food availability would result in lower prices, leading to changes in consumer behavior.

Omega-3 fatty acids appear promising for maintaining lung health

A new study found that omega-3 fatty acids, particularly docosahexaenoic acid (DHA), are associated with reduced lung function decline and better lung health. The research supports the inclusion of omega-3 fatty acids in the diet to promote lung health.

Study finds European breeding birds respond only slowly to recent climate change

A new study found that European breeding birds have shifted their ranges by an average of 2.4km per year over the last 30 years, but these changes were not as rapid as predicted based on climate change alone. Local factors such as habitat availability and population connectivity played a key role in determining range shifts.
