Dogs, cats, monkeys, worms, fish--they've all been made to glow in the dark, thanks to one jellyfish and a whole lot of research. In this photo round-up of glowing animals (and the odd plant), see what science has done with a few fluorescent proteins.
The space shuttle Atlantis sustained minor damage to its thermal tiles during its Monday launch, likely from debris that came off the fuel tank after lift off. Video.
Superman has nothing on the collapsed cores of massive snuffed-out stars, which constitute the strongest known material in the universe, a new study says.
