Asteroids are thought to be the source for much of the water on Earth, but Hayabusa2 has found Ryugu to be surprisingly dry — unlike asteroid Bennu, which is currently being orbited by the Osiris-Rex spacecraft. Hayabusa2 briefly touched the asteroid, fired a projectile into the rock
Octopuses are smart. They open jars, steal fish and high-five each other. Though interactive, they’re generally asocial, and temperamental, with unique behavior patterns, like those shown by Otto, who caused blackouts at a German aquarium and Inky, who famously escaped a tank in New Zealand.

You have a gene called PNMA6F. All people do, but no one knows the purpose of that gene or the protein it makes. And as it turns out, PNMA6F has a lot of company in that regard. In a study published Tuesday in PLOS Biology, researchers at Northwestern University reported that of our 20,000 protein-coding genes, about 5,400 have never been the subject of a single dedicated paper. Most of our other
