scientists-replayed-evolution-and-found-a-surprise

Environmental change doesn’t affect evolution in a single, predictable way. In large-scale computer simulations, scientists discovered that some fluctuating conditions help populations evolve higher fitness, while others slow or even derail progress. Two populations facing different kinds of change can end up on completely different evolutionary paths. The findings challengeContinue Reading

curiosity-sends-holiday-postcard-from-mars

NASA/JPL-Caltech Team members working with NASA’s Curiosity Mars rover created this “postcard” by commanding the rover to take images at two times of day on Nov. 18, 2025, spanning periods that occurred on both the 4,722nd and 4,723rd Martian days, or sols, of the mission. The panoramas were captured atContinue Reading

Frattare Celebrate the New Year with the “Champagne Cluster,” a galaxy cluster seen in this new image from NASA’s Chandra X-ray Observatory and optical telescopes. Astronomers discovered this galaxy cluster Dec. 31, 2020. The date, combined withContinue Reading

a-gold-catalyst-just-broke-a-decade-old-green-chemistry-record

A new catalyst design could transform how acetaldehyde is made from renewable bioethanol. Researchers found that a carefully balanced mix of gold, manganese, and copper creates a powerful synergy that boosts efficiency while lowering operating temperatures. Their best catalyst achieved a 95% yield at just 225°C and stayed stable forContinue Reading
