Astronomers spot the pebbles that turn into planets
Astronomers believe that planets form from disks of dust and gas that swirl around young stars. Models suggest that gravity clumps the dust together into tiny pebbles that in turn form larger rocks that eventually become planets. Whereas scientists have seen disks of gas and of dust, the intervening phases between dust and planet have…

Your brain is like a wad of paper
Whether they’re from humans, whales, or elephants, the brains of many mammals are covered with elaborate folds.

That observation suggests that the myriad forms of mammalian brains arise not from…
