Researchers continue to study how these mountain goats navigate nearly vertical terrain with astonishing ease. Their specialized hooves and powerful hind limbs allow them to grip surfaces that appear ...

A decade-long investigation into puzzling neutrino behavior has now ruled out one of the most widely discussed explanations: the sterile neutrino.

When a gas is highly energized, its electrons get torn from the parent atoms, resulting in a plasma—the oft-forgotten fourth ...

The parabolic flight travels up and down several times on a trajectory resembling an arch, providing 22 seconds of zero ...

The idea that we might be living in a simulated reality has worried us for centuries. Now physicists have found some ...

This study shows that the universe itself can push the boundaries of physics in ways laboratory tests cannot. By ruling out ...

Dusty stars close to the Milky Way’s black hole stay stable for years. New infrared data shows they survive gravity and ...

Two University of Wisconsin researchers Edgar Spalding and Takeshi Yoshihara recently published a study concluding that there ...

For three decades, a riddle has followed neutrinos, the near-weightless particles that stream through Earth by the trillions each second. They change identities as they fly, shifting among three known ...

This temporal lag is a direct consequence of Albert Einstein’s Theory of General Relativity. The rule is simple: the weaker ...
