Cornell materials scientists and bioelectrochemical engineers may have created an innovative, cost-competitive electrode material for cleaning pollutants in wastewater.

A group of researchers led by Osaka University developed an early detection method for cow lameness (hoof disease), a major disease of dairy cattle, from images of cow gait with an accuracy of 99% or higher by applying human gait analysis. This technique allows early detection of lameness from cow gait, which was previously difficult. It is hoped that a revolution in dairy farming can be achieved through detailed observation by AI-powered image analysis.

Recent increases in an unregulated ozone-depleting substance, could delay recovery of Antarctic ozone levels by 5–30 years, depending on emissions scenarios.

The findings, published in Nature Communications, suggest that a previously ignored chemical called dichloromethane may now be contributing to ozone depletion and should be considered to improve future ozone predictions.

Rice University scientists have fabricated a durable catalyst for high-performance fuel cells by attaching single ruthenium atoms to graphene.

Catalysts that drive the oxygen reduction reaction that lets fuel cells turn chemical energy into electricity are usually made of platinum, which stands up to the acidic nature of the cell’s charge-carrying electrolyte. But platinum is expensive, and scientists have searched for decades for a suitable replacement.

Now a tropical storm, Hurricane Dora has been skirting southwestern Mexico’s coast since it formed and has transported tropical moisture onshore that has produced some heavy rain showers. The Global Precipitation Measurement mission or GPM core satellite has analyzed those rainfall rates.
