Doggone: wet pet food "seven times worse" for climate than dry
Feeding cats and dogs wet food has a much larger climate impact than dry food, a new study found, suggesting small changes by pet owners can massively reduce their carbon footprint......»»
NASA"s IXPE helps solve black hole jet mystery
Some of the brightest objects in the sky are called blazars. They consist of a supermassive black hole feeding off material swirling around it in a disk, which can create two powerful jets perpendicular to the disk on each side. A blazar is especiall.....»»
The Eocene rise of eastern Tibet drove an ancient monsoon that modernized Asian biodiversity
Today East Asia, and in particular the Hengduan Mountains and other parts of southwestern China, hosts several of Earth's great biodiversity "hotspots." A biodiversity hotspot is where very large numbers of unique species are under threat of extincti.....»»
A cosmic hourglass: Webb captures image of protostar swathed in dark clouds
