An asteroid passed 428 km from Earth and no one saw it coming - Boing Boing

Fossils unearthed in China reveal complex, three-dimensional animals thriving 539 million years ago—millions of years earlier than thought. The discovery challenges long-held theories about the Ediacaran period and the rise of modern animal life.

Physicists at the University of Waterloo and Perimeter Institute propose a radical new quantum gravity theory that eliminates the need for inflation to explain the Big Bang. Their quadratic gravity model suggests cosmic expansion arose naturally from quantum effects, offering testable predictions fo

A fossil site in China’s Yunnan Province reveals complex animal groups existed 554–539 million years ago, pushing back the origins of vertebrates and starfish relatives by 4 million years before the Cambrian explosion.
