Uranium Tech Could Open Easy Path to the Bomb

But GE says laser enrichment could help US energy security

(Newser) - Advances in uranium enrichment using lasers by General Electric could allow the US conglomerate to process reactor fuel by the ton—but security experts fear the technology could also allow rogue states and terrorist groups to make bomb fuel much more easily, in smaller plants that would be much harder...

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 »

Russian Ravers Lose Sight After Laser Show

Vision loss as high as 80% and 'impossible to regain'

(Newser) - Several partygoers at a Russian rave lost part of their sight to damage from a laser light show, Reuters reports. Dozens have appeared at Moscow hospitals for treatment of retinal burns. Loss of vision is as high as 80% and "regaining it is impossible," according to one ophthalmologist.... More »

Sun Banks on Lasers to Make Next Speed Leap

Using light, not wires, to connect chips could make computers 1,000 times faster

(Newser) - Sun Microsystems is moving toward connecting computer chips using lasers instead of wires, a move that could make computers 1,000 times faster. The company snagged a $44 million Pentagon contract to continue work that could also mean smaller, more energy-efficient machines. It won’t be easy, though: A Sun... More »

Lasers Able to Zap Viruses

Find the right frequency, and they shatter like a wine glass

(Newser) - Laser pulses tuned to the right frequency can be used to zap viruses, researchers have found, the way a soprano can shatter a wine glass, LiveScience reports. Scientists have developed computer models to determine a virus's lowest resonant frequency, and then destroy it with a laser pulse. "Like pushing... More »
