New research published in BMJ Nutrition, Prevention & Health found that a low-fat vegan diet reduced food-related greenhouse gas emissions by 57%—nearly three times more than a Mediterranean diet—while also improving key cardiometabolic outcomes.

A study published in Current Developments in Nutrition shows that adopting a low-fat vegan diet reduces diet-related greenhouse gas emissions by 55% and cumulative energy demand by 44%—dramatic reductions achieved in just 12 weeks.

New UCLA research finds that airborne dust traps about twice as much heat as climate models have estimated, even though dust likely cools the planet overall. The effect of dust retaining heat is equal to roughly 10%, not the previously calculated 5%, of the warming effect of human-emitted carbon dioxide, one of several greenhouse gases. These new findings could increase precision in climate models and weather forecasts.

Downbursts are intense, short-duration radial winds from thunderstorms that pose severe risks near the ground to transport and civil infrastructure. This study develops an analytical model of downburst velocity and pressure fields that reproduces key observed features in the near-ground region. Applied to trains, parametric and stochastic analyses show that overturning risk depends on train speed, downburst motion and relative position. Reducing train speed noticeably lowers accident risk, with unloaded freight trains being most vulnerable.
