Repulsive Force Discovered In Light
Aurispector writes in with news that the Yale team that recently discovered an attractive force between two light beams in waveguides has now found a corresponding repulsive force. "'This completes the picture,' [team lead Hong] Tang said. 'We've shown that this is indeed a bipolar light force with both an attractive and repulsive component.' The attractive and repulsive light forces Tang's team discovered are separate from the force created by light's radiation pressure, which pushes against an object as light shines on it. Instead, they push out or pull in sideways from the direction the light travels. Previously, the engineers used the attractive force they discovered to move components on the silicon chip in one direction, such as pulling on a nanoscale switch to open it, but were unable to push it in the opposite direction. Using both forces means they can now have complete control and can manipulate components in both directions. 'We've demonstrated that these are tunable forces we can engineer,' Tang said."
Sweet! Next up, how lightsabers don't work.
Just like my ex-girlfriend!

If you aren't suspicious of your government's actions, you aren't doing your job as a responsible citizen.
"Repulsive Force Discovered In Light"--well DUH. Anyone who's ever been in a strip club at closing time has witnessed this phenomenon.
Dear Slashdot: next time you want to mess with the site, add a rich-text editor for comments.
Actually, it's your spelling.
Anything, as long as you divert enough power to the deflector dish.
Now emits 100% attractive light. That's twice as much as the next leading brand!
What the crap is an article about a newly found force that doesn't explain at least a theory as to the source of the force? Is it magnetic?
Don't worry. I'm sure some physicist somewhere will soon invent a particle to explain it.

I already knew that light repelled me.
This was previously demonstrated by cockroaches.

Going around assuming lewdness where none exists can get you into big trouble.

Bingo, Sir.
