Although overhunting led to the demise of some prehistoric megafauna after the last ice age, a new study found that the extinction of the woolly rhinoceros may have been caused by climate change. By sequencing ancient DNA from 14 woolly rhinos, researchers found that their population remained […]

New theoretical research finds that many white dwarfs may explode in supernova in the distant far future, long after everything else in the universe has died and gone quiet.

In a proof-of-concept study, researchers report that a simple, low-cost technique provided visual proof that face masks are effective in reducing droplet emissions during normal wear. They found that the best face coverings were N95 masks without valves -- the hospital-grade coverings that are used […]

Data from NASA's recent Dawn mission answers two long-unresolved questions: Is there liquid inside Ceres, and how long ago was the dwarf planet geologically active?

A new study supports predictions that the Arctic could be free of sea ice by 2035.

Plants are factories that manufacture yield from light and carbon dioxide -- but parts of this complex process, called photosynthesis, are hindered by a lack of raw materials and machinery. To optimize production, scientists have resolved two major photosynthetic bottlenecks to boost plant […]
