Printable holograms could make holograms more widespread

(—Holograms have a wide variety of applications, from 3D displays to data storage, but the potential applications are currently limited by the complexity and cost of hologram fabrication. In an attempt to simplify ...

Researchers learn how to steer the heart—with light

We depend on electrical waves to regulate the rhythm of our heartbeat. When those signals go awry, the result is a potentially fatal arrhythmia. Now, a team of researchers from Oxford and Stony Brook universities has found ...

Physicists develop key component for terahertz wireless

Terahertz radiation could one day provide the backbone for wireless systems that can deliver data up to one hundred times faster than today's cellular or Wi-Fi networks. But there remain many technical challenges to be solved ...

Short wavelength plasmons observed in nanotubes

The term "plasmons" might sound like something from the soon-to-be-released new Star Wars movie, but the effects of plasmons have been known about for centuries. Plasmons are collective oscillations of conduction electrons ...

Bringing back the magic in metamaterials

A single drop of blood is teeming with microorganisms—imagine if we could see them, and even nanometer-sized viruses, with the naked eye. That's a real possibility with what scientists call a "perfect lens." The lens hasn't ...
