Penn State engineers have used a "white-light laser" to produce a new type of optical "tweezers" that not only traps, holds and moves microscopic objects but also can perform characterization of the ...

Star Trek fans will remember "tractor beams," lasers that allowed the Starship Enterprise to trap and move objects. Tel Aviv University is now turning this science fiction into science fact -- on a ...

When you’re working with tiny nanoparticles, you need extremely delicate tools. Like, say, tweezers that can manipulate particles 1,000 times thinner than a human hair without physically touching them ...

(Nanowerk News) We can test the quality and freshness of fruits and vegetables with our fingers, and even industrial robots have been performing successfully at tactile applications for years. But how ...

Add Yahoo as a preferred source to see more of our stories on Google. The look of your eyebrows can change your entire appearance, so it’s no secret we go to great lengths to perfect them. From growth ...

With an increasing focus on brows, it is no surprise sales of the tools to perfect them are climbing. With volume on the rise, LaTweez, the company that invented and holds the patent for light-up ...

Nano grip Researchers have built the world's smallest tweezers, capable of picking up a single virus or molecule. The device could be a boon for scientists who want to manipulate biological specimens ...

Using beams of light to hold molecules in place or tug at them, researchers have directly measured the strength of protein chemical bonds and could tease out more cellular secrets. Cynthia Graber ...
