Researchers at NJIT have developed a flexible battery made with carbon nanotubes that could potentially power electronic devices with flexible displays.Electronic manufacturers are now making flexible organic light-emitting diode (OLED) displays, a pioneering technology that allow devices such as cell phones,...

MIT researchers have come up with a way to cool hot surfaces more effectively by keeping droplets from bouncing. Their solution: Decorate the surface with tiny structures and then coat it with particles about 100 times smaller. Using that approach, they produced textured surfaces that...

Researchers have created a “RoboSnail,” which can climb walls and stick to overhead surfaces much like its living counterpart. Such a device has potential uses in invasive surgery and oil well drilling, among other applications.The researchers found that, while digging, the clam’s up-and-down movement...

An in-flight service from Gogo allows travelers to text and talk as if they are on the ground. By using the company's air-to-ground connectivity, calls and texts are routed through the aircraft's wireless network rather than in-flight cell towers, or "picocells."

A string of fiber-optic sensors running along a 36-km stretch of high-speed commuter railroad lines connecting Hong Kong to mainland China has taken more than 10 million measurements over the past few years in a demonstration that the system can help safeguard commuter trains and freight cars against...

Silence isn’t just golden, it’s an absolute necessity for Binghamton University Professor Ron Miles. Miles’ current work involves building a better hearing aid, and for that he needs an extraordinarily quiet room. The University’s new anechoic chamber (a room without echo) is the...

Researchers at Carnegie Mellon University and Disney Research Pittsburgh have devised a motion tracking technology that could eliminate much of the annoying lag that occurs in existing video game systems that use motion tracking, while also being extremely precise and highly affordable. Called Lumitrack,...

Researchers from Georgia Tech, the University of Tokyo, and Microsoft Research have developed a novel method to rapidly and cheaply make electrical circuits by printing them with commodity inkjet printers and off-the-shelf materials. For about $300 in equipment costs, anyone can produce working electrical...

Using inexpensive materials configured and tuned to capture microwave signals, researchers at Duke University’s Pratt School of Engineering have designed a power-harvesting device with efficiency similar to that of modern solar panels.The device wirelessly converts the microwave signal to...

Inspired by the way dolphins hunt using bubble nets, scientists at the University of Southampton, in collaboration with University College London and Cobham Technical Services, have developed a new kind of radar that can detect hidden surveillance equipment and explosives. The twin inverted...

A remote acoustic detection system designed to identify homemade bombs can determine the difference between those that contain low-yield and high-yield explosives. That capability – never before reported in a remote bomb detection system – was recently described in a paper by Vanderbilt engineer Douglas...

As new technologies emerge and new cyber and electronic warfare threats plague soldiers in the field, U.S. Army scientists and engineers continue to define next-generation protocols and system architectures to help develop the technology to combat these threats in an integrated and...

A StarChase system being used by police in Florida and Iowa allows police officers to fire "a miniature GPS module encased in a tracking projectile/tag" from a "launcher" mounted on a police cruiser's grill. The GPS module then sticks to the rear of the fleeing car, allowing dispatch to track the...

Researchers from the University of Helsinki's Department of Chemistry have manufactured photochemically active polymers which can be dissolved in water or certain alcohols.The effect where light causes the polymer to dissolve completely and be made visible can last several hours depending, for example, on the...

Nik Karpinsky quickly tapped out a few computer commands until Zeus, in all his bearded and statuesque glory, appeared in the middle of a holographic glass panel mounted to an office desk.The white statue stared back at Karpinsky. Then a hand appeared and turned the full-size head to the right and to...

It was a result so unexpected that MIT researchers initially thought it must be a mistake: Under certain conditions, putting a cracked piece of metal under tension — that is, exerting a force that would be expected to pull it apart — has the reverse effect, causing the crack to close and its...

Using technology found in cellphones, inexpensive sensors might one day soon save lives by giving advance warning of deadly landslides in at-risk areas around the world. The wireless test sensors are installed around an active landslide zone.

Examination of the Martian atmosphere by NASA's Curiosity Mars rover confirms that some meteorites that have dropped to Earth really are from the Red Planet. A key new measurement of the inert gas argon in Mars' atmosphere by Curiosity's laboratory provides the most definitive evidence...

World View Enterprises will offer $75,000 helium balloon rides into “near space," allowing people to ride higher than 98,000 feet above Earth’s atmosphere.

A small, easy-to-use, lightweight explosive screening kit continues to move forward towards full fielding as a means to provide soldiers in the field with the capability to screen for suspected homemade explosive materials (HME). Using colorimetric chemistry, the Colorimetric Reconnaissance...

In remote regions of the world where electricity is hard to come by and scientific instruments are even scarcer, conducting medical tests at a doctor’s office or medical lab is rarely an option. Scientists are now reporting progress toward an inexpensive point-of-care, paper-based...

NASA has joined forces with the product development startup Marblar for a pilot program allowing the public to crowdsource product ideas for forty of NASA’s patents. This initiative will allow Marblar’s online community to use a portion of NASA’s diverse portfolio of patented...

Researchers at the University of Colorado Boulder have successfully added a fourth dimension to their printing technology, opening up exciting possibilities for the creation and use of adaptive, composite materials in manufacturing, packaging and biomedical applications.

The current generation of satellite launch vehicles is expensive to operate, often costing hundreds of millions of dollars per flight. To help address these challenges, DARPA has established the Experimental Spaceplane (XS-1) program. The program aims to develop a fully reusable...

Researchers have developed a measuring system which, hanging from a helicopter, detects the electric field strength as well as the signal contents of air-traffic control navigation systems. The data could be used in the planning phase of wind farms to find out to what extent the planned wind...

A temperature sensor developed by researchers at the University of Cambridge could improve the efficiency, control, and safety of high-temperature engines. The sensor minimizes drift -- degradation of the sensor that results in faulty temperature readings and reduces the longevity of engine...

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory investigated the effects of differently shaped, nanoscale textures on a material's ability to force water droplets to roll off without wetting its surface. The findings are highly relevant for a broad range of...
