Extraterrestrial Stone Found in Egypt May Be First Evidence on Earth of Rare Supernova

‘Standard candle’ (or type Ia) supernova explosions are some of the most energetic events in the Universe, happening when a dense white dwarf star subsumes another star. Now, scientists think they’re found the first evidence on Earth of such a supernova. The claim comes after a careful study of the extraterrestrial Hypatia stone that was … Read more

Octopuses torture and eat themselves after mating. Science finally knows why.

Many animal species that reproduce after they. But in octopus mothers, this decline is particularly alarming: In most species, as an octopus mother’s eggs get close to hatching, she stops eating. She then leaves her protective huddle over her brood and becomes bent on self-destruction† She might beat herself against a rock, tear at her … Read more

Jones and Muhua Sun/Rice University Scientists have demonstrated a new material that conducts heat 150% more efficiently than conventional materials used in advanced chip technologies. The device—an ultrathin silicon nanowire—could enable smaller, faster microelectronics with a … Read more
