Tractor Beams Come To Life 127
Jamie is helping bring our childhood fantasies/nightmares to life with a link that says "Andrei Rhode, a researcher involved with the project, said that existing optical tweezers are able to move particles the size of a bacterium a few millimeters in a liquid. Their
new technique can move objects one hundred times that size over a distance of a meter or more."

Until the bacterium reroute the main power conduits through the deflector beam to create an inverse tachyon pulse. Then what?

Tractor beams attract. A flashlight has more in common with a light saber, than this has with a tractor beam.
Enough with the sensationalism, already. Leave that to the CNNs and Fox News's.. If you don't understand the science in an article, consider waiting for someone smarter than you to post it.
News for mooncalves. Stuff thats way the fsck beyond your meager comprehension.

Because it's a shitty title to a story about advances in optical tweezers which need an ambient gas like air to work and has nothing to do with tractor beams in space (like TFA says)? And you just want to make a shitty pun, which will no doubt be followed up with another shitty pun about ambient gas?
My cheerios, there is piss in them.

I think you meant deflector array. Otherwise there's no way such a silly thing could happen. :p

This tech will do no good in keeping those pesky rebels from escaping your space station.

If somebody makes a beam that can move something bigger than a bacterium around I'll be impressed whether it works in space or not.
As for your cheerios, perhaps you should label your liquids better.

"The device works by shining a hollow laser beam around tiny glass particles. The air surrounding the particle heats up, while the dark center of the beam stays cool. When the particle starts to drift out of the middle and into the bright laser beam, the force of heated air molecules bouncing around and hitting the particle's surface is enough to nudge it back to the center."
So if you take two or more lasers place them on opposite sides of where you want to pull something. Point the lasers at the object. Then slowly turn the beams towards the middle. Tada. You've pulled your object to you.
In other news, I only use repulsive forces on with hand to pick up things (other forces too minor to consider), yet some how I still manage to pull things towards myself.

No, it just doesn't work. Just doesn't set up the scene correctly at all.
