Scientists Create 'Living Laser'

Technique could change light-based, imaging therapies

(Newser) - Scientists have been genetically engineering organisms that glow for years, but now a team at Massachusetts General has taken the technology to a new level—to create a "living laser." They aren't blasting death rays (yet), but scientists have coaxed single cells, derived from human kidneys, to... More »

NASA May Move Space Junk With Lasers

Idea isn't to destroy pieces, but to prevent more collisions

(Newser) - What to do about all that space junk floating around Earth? A team of NASA scientists has a novel way to at least help manage the mess, reports Wired : Use lasers to push pieces on collision courses away from one another. The idea is to prevent smash-ups that create even... More »
