Do-it-yourself invisibility with 3-D printing

Seven years ago, Duke University engineers demonstrated the first working invisibility cloak in complex laboratory experiments. Now it appears creating a simple cloak has become a lot simpler.

Researchers create novel optical fibers

(Phys.org) —Researchers at the University of Wisconsin-Milwaukee (UWM) have found a new mechanism to transmit light through optical fibers. Their discovery marks the first practical application of a Nobel-Prize-winning ...

No more blind spots: Researchers design new rearview mirror

(Phys.org)—A new optical prescription for automobile side-view mirrors may eliminate the dreaded "blind spot" in traffic without distorting the perceived distance of cars approaching from behind. As described in a paper ...

'Nanotubes on a chip' could simplify optical power measurements

(Phys.org)—The National Institute of Standards and Technology (NIST) has demonstrated a novel chip-scale instrument made of carbon nanotubes that may simplify absolute measurements of laser power, especially the light signals ...

A 3-D light switch for the brain

A new tool for neuroscientists delivers a thousand pinpricks of light to a chunk of gray matter smaller than a sugar cube. The new fiber-optic device, created by biologists and engineers at the Massachusetts Institute of ...

Laser-powered 'needle' promises pain-free injections

From annual flu shots to childhood immunizations, needle injections are among the least popular staples of medical care. Though various techniques have been developed in hopes of taking the "ouch" out of injections, hypodermic ...
