Mobile Device Can Sense a Stranger’s Touch

Mobile Device Can Sense a Stranger’s Touch

Passwords, gestures and fingerprint scans are all helpful ways to keep a thief from unlocking and using a cell phone or tablet. Cybersecurity researchers from the Georgia Institute of Technology have gone a step further. They’ve developed a new security system that continuously monitors how a user taps and swipes a mobile device. If the [...]

Optical Tweezers Split Ultracold Atom Clouds

Optical Tweezers Split Ultracold Atom Clouds

Physicists at New Zealand’s University of Otago have pushed the frontiers of quantum technology by developing a steerable ‘optical tweezers’ unit that uses intense laser beams to precisely split minute clouds of ultracold atoms and to smash them together.   The Otago researchers’ feat is set to enhance efforts to understand the mysterious ways that [...]

Logical Circuits Built Using Living Slime Molds

Logical Circuits Built Using Living Slime Molds

A future computer might be a lot slimier than the solid silicon devices we have today. In a study published in the journal Materials Today, European researchers reveal details of logic units built using living slime molds, which might act as the building blocks for computing devices and sensors.   Andrew Adamatzky (University of the [...]

Invisibility Cloak for Hearing Aids, Implants

Invisibility Cloak for Hearing Aids, Implants

Microsystems are at the heart of portable hearing aids and implants. Now researchers are developing a miniature, low-power wireless microsystem to make these medical aids smaller, more comfortable and more efficient.   People with impaired hearing struggle with things we take for granted, whether it is listening to birds warbling in the garden or chatting [...]

Warping Images Using Your PC Graphics Card

Warping Images Using Your PC Graphics Card

By projecting images onto contoured surfaces you get a virtual experience that puts you at the center of the action. Now, a quick and easy calibration technique could help the concept find a wider application beyond the planetarium.   It’s almost as if you were weightless. You can reach out and touch the Big Dipper [...]

Mind-Reading Robots Coming Ever Closer

Mind-Reading Robots Coming Ever Closer

If you think with the release of every new i-device the world is getting closer to thought-controlled smart tech and robotic personal assistants, you might be right.   And thanks in part to work led by the University of Cincinnati’s Anca Ralescu, we may be even closer than you realize. Professor Ralescu of the Department [...]

Thin, Active Invisibility Cloak Demonstrated for First Time

Thin, Active Invisibility Cloak Demonstrated for First Time

Invisibility cloaking is no longer the stuff of science fiction: two researchers in The Edward S. Rogers Sr. Department of Electrical & Computer Engineering have demonstrated an effective invisibility cloak that is thin, scalable and adaptive to different types and sizes of objects.   Professor George Eleftheriades and PhD student Michael Selvanayagam have designed and [...]

Software Uses Cyborg Swarm to Map Unknown Environs

Software Uses Cyborg Swarm to Map Unknown Environs

Researchers from North Carolina State University have developed software that allows them to map unknown environments — such as collapsed buildings — based on the movement of a swarm of insect cyborgs, or “biobots.”   “We focused on how to map areas where you have little or no precise information on where each biobot is, [...]

World Record: Wireless Data Transmission at 100 Gbit/S

World Record: Wireless Data Transmission at 100 Gbit/S

Extension of cable-based telecommunication networks requires high investments in both conurbations and rural areas. Broadband data transmission via radio relay links might help to cross rivers, motorways or nature protection areas at strategic node points, and to make network extension economically feasible. In the current issue of the nature photonics magazine, researchers present a method [...]
