Scientists have found a way to bend lasers — and may use it to bend lightning as well.

A team led by Pavel Polynkin of the University of Arizona sent a special sort of laser beam — pulsed instead of steady, and asymmetrical so that one edge was brighter than the other — through a series of filters.

They found that the beam actually curved a bit, by about 5 millimeters (about 1/5 of an inch) over the total distance of 60 centimeters (2 feet).

"People expect lasers to do certain things, like propagate in a straight line," Polynkin told Scientific American. "The fact that a laser beam actually curves is quite unusual."

Since the laser pulses are so intense, they zap the air they pass though, leaving behind an ionized plasma trail. That trail might be conductive enough to form a natural pathway for lightning to travel along, points out Jérôme Kasparian at the University of Geneva.

Kasparian, who's been trying to coax lightning from thunderclouds using straight plasma beams, thinks Polynkin's curved beams could be used to divert lightning toward or away from specific targets.

"It would be fun to see curved lightning discharges," he told New Scientist.

'Teenage Mutant Ninja Turtles' creator Peter Laird speaks

out on Michael Bay controversy

"Teenage Mutant Ninja Turtles" co-creator Peter Laird thinks

Michael Bay is a genius. Well, sort of.

Responding to a recent spate of outrage by die-hard fans after

Bay revealed that the new "TMNT" movie he's producing will go

against franchise lore by having the superheroes hail from an

"alien race", Laird called for the director's critics to "swallow the

'chill pill' Mr. Bay recently suggested they take, and wait and see

what might come out of this seemingly ill-conceived plan."

Ok...so where does the "genius" part come in, exactly?

"It's possible that with enough truly creative brainpower

applied to this idea, it might actually work," Laird continued, in

an entry on his personal TMNT blog. "I'm not saying it's

probable, or even somewhat likely… but it IS possible. However,

as I have pondered this further, I have realized that in one way

it IS truly a genius notion."

Genius, says Laird, because after years and years of being

pitched the idea of adding a fifth turtle, "for the first time --

someone has come up with a way to have as many freakin'

Turtles as they want. I mean, if the TMNT are actually members

of an alien race, there could be a whole PLANET of them!"

Oh, sweet, sweet irony...

All of that said, it doesn't much matter what Laird thinks at this

point, considering he no longer holds the rights to the

property. In other words, quit emailing him with requests to put

a stop to Bay's alleged bastardization of the franchise. There's

nothing he can do!

Oh, and P.S. by the way, adding Turtle babe Venus de Milo to

the short-lived "Teenage Mutant Ninja Turtles: The Next

Mutation" totally wasn't his idea.
