Evidence suggests saber-toothed cats held onto their baby teeth to stabilize their sabers

California's state fossil—are familiar to anyone who has ever visited Los Angeles' La Brea Tar Pits, a sticky trap from which more than 2,000 saber-toothed cat skulls have been excavated over more than a century.

The spontaneous emergence of 1D superconducting stripes at a 2D interface in an oxide heterostructure

Unconventional superconducting states are states of superconductivity rooted in physical processes that do not conform with the conventional theory of superconductivity, namely Bardeen, Cooper and Schrieffer (BCS) theory. ...

Exploding stars are rare but emit torrents of radiation—one close enough to Earth could threaten life on the planet

Stars like the sun are remarkably constant. They vary in brightness by only 0.1% over years and decades, thanks to the fusion of hydrogen into helium that powers them. This process will keep the sun shining steadily for about ...
