Rice engineers demo first T-ray endoscope

Technology could aid explosive detection, cancer screening, more

Electrical engineers at Rice University in Houston have demonstrated the world’s first endoscope for terahertz imaging, a discovery that could extend the reach of terahertz-based sensors for applications as wide-ranging as explosives detection, cancer screening and industrial and post-production quality control.

The research appears in the Nov. 18 issue of the journal Nature. It presents the emerging te

Sensor network mimics synchronized calling by frogs and cicadas

The modern world is filled with the uncoordinated beeping and buzzing of countless electronic devices. So it was only a matter of time before someone designed an electronic network with the ability to synchronize dozens of tiny buzzers, in much the same way that frogs and cicadas coordinate their night-time choruses.

“Several years ago I was on a camping trip and we pitched our tent in an area that was filled with hundreds of tree frogs,” says Kenneth D. Frampton, an assistant prof

Bio-inspired modules open new horizons for robotics

Inspired by cell biology, European researchers have created the world’s first shape-shifting robot made of many modules, which could lead to new applications in fields ranging from medicine and space exploration to education and entertainment.

On display at IST 2004 in The Hague and being showcased on 17 November in Tokyo, the HYDRA project’s robots have broken new ground in robotics and artificial intelligence through a simple but highly effective design that allows the device

Green car sets speed record

When the non-profit organisation IdéeVerte Compétition decided to create a ’green’ racing car, they turned to space technology to make it safer. Running on liquefied petroleum gas, one of the least polluting fuels, and lubricated with sunflower oil, the car is protected against fire hazards by space materials. ’Green’ does not have to mean slow – last week the car set a new speed record of 315 km/h.

“The car of the future will have to respect the environment. This is the only

New Transistor Laser Could Lead To Faster Signal Processing

Researchers at the University of Illinois at Urbana-Champaign have demonstrated the laser operation of a heterojunction bipolar light-emitting transistor. The scientists describe the fabrication and operation of their transistor laser in the Nov. 15 issue of the journal Applied Physics Letters. “By incorporating quantum wells into the active region of a light-emitting transistor, we have enhanced the electrical and optical properties, making possible stimulated emission and transis

Sandia, Stirling to Build Solar Dish Engine Power Plant

The National Nuclear Security Administration’s Sandia National Laboratories is joining forces with Stirling Energy Systems, Inc. (SES) of Phoenix to build and test six new solar dish-engine systems for electricity generation that will provide enough grid-ready solar electricity to power more than 40 homes.

Five new systems will be installed between now and January at Sandia’s National Solar Thermal Test Facility. They will join a prototype dish-Stirling system that was er
