SNOWBALL EARTH
Popular Mechanics US
|January - February 2025
IMAGINE A PLANET WHERE THE AVERAGE temperature is a delightful -58° Fahrenheit every day. Not a place you'd want to visit, right? Lucky for you, then, that you weren't around several hundred million years ago, because these brutal conditions were the unfortunate reality of the "Snowball Earth."
Between roughly 640 and 720 million years ago, Earth was covered pole to pole with slush and ice. During two major ancient freezes, the way our planet must have looked from space at the time has prompted the nickname Snowball Earth. And now, researchers may have just found the world's most complete record of this period of glaciation in part of a rock formation known as the Port Askaig Foundation.

GARFIELD MIGHT BE THE MOST ICONIC orange tabby cat around, but he has so far refused to give up orange tabbies' most guarded beauty secret-how do they get their auburn coats? Hiroyuki Sasaki, a cat enthusiast and geneticist at Kyushu University in Japan, was determined to identify the elusive gene that carries the orange mutation in Felis silvestris catus (the domesticated cat).
