Low-Cost Biofuel

University of Maryland researchers have created a process to convert large volumes of plant products, from leftover brewer's mash to paper trash, into ethanol and other biofuel alternatives to gasoline. Developed by University of Maryland professors Steve Hutcheson and Ron Weiner, the technique, called the Zymetis process,...

Haptic Interface

Carnegie Mellon University researchers have developed a touch-based, or haptic, interface that could allow people to realistically feel textures and shapes of 3-D designs created on computers. The system involves a single lightweight moving part that floats on magnetic fields. Magnetic levitation eliminates the need for...

Alleviating Arthritis

About 46 million people suffer from arthritis in the United States alone. The worst cases require painful surgeries to drill holes in and reinforce joints. Now, researchers working at the National Institute of Standards and Technology (NIST) are studying an unusually pliant, yet strong, synthetic cartilage replacement in...

Plant Toxin

A powerful plant toxin widely feared for its bioterrorism potential may one day be tamed using findings about how the toxin attacks cells. The findings may also help scientists combat food poisoning episodes.

According to biotechnology researchers at Rutgers University, ricin, extracted from castor beans, tricks a cell into...

Anti-Piracy Chip

Computer engineers at the University of Michigan and Rice University hope to solve the growing problem of chip patent infringement through a cryptography scheme that assigns each chip a unique lock and key. Called EPIC for Ending Piracy of Integrated Circuits, the technique relies on established cryptography methods, adding...

Tech Briefs

Integrated microbatteries have been proposed to satisfy an anticipated need for long-life, low-rate primary batteries, having volumes less than 1 cubic millimeter, to power electronic circuitry in implantable medical devices. In one contemplated application, such a battery would be incorporated into a tubular hearing-aid device to be...

Cell Phones and Driving

If there was any doubt that cell phones distract drivers, one needs to look no further than a study by Carnegie Mellon University scientists that concludes that drivers engaged in cell phone use commit some of the same driving errors that can occur under the influence of alcohol.

The study examined 29 volunteers...

Current Attractions

According to Edward Austin, Science and Mission Operation Project Manager for the Stratospheric Observatory for Infrared Astronomy (SOFIA), there are a lot of things that are obscured in the galaxy that we would want to see. We can use infrared technology, but a lot of the infrared spectrum is actually blocked by water vapor...

"Two-Faced" Particles

Researchers at North Carolina State University have demonstrated that Janus particles - microscopic "two-faced" spheres whose halves are physically or chemically different - will move like little submarines when an alternating electrical field is applied to the liquid surrounding them. The micrometer-sized particles convert...

Earthquake

Three-hundred years ago, the Juan de Fuca plate under the ocean in America's Pacific Northwest suddenly slipped beneath the North American plate and forced its way about 60 feet eastward, triggering a massive earthquake that scientists estimate was roughly magnitude 9.0. The quake was so large that the tsunamis it created traveled all...

NASA Briefs

An optical filter consisting of a multilayer spectral coating on a flexible membrane has been designed by NASA's Jet Propulsion Laboratory to be placed in front of the 200-inch Hale telescope on Mt. Palomar. The filter is intended to protect the telescope against solar radiant flux and limit solar heating of the interior of the...

Live Cancer Gene

Researchers at Stony Brook University Medical Center have identified a family of genes linked to the development of liver cancer. Led by Wadie F. Bahou, M.D., Professor of Medicine and Genetics, the team discovered in a mouse model that the loss of one specific gene (Iqgap2) in this family causes Hepatocellular carcinoma (HCC),...

Overtaking Assistant

Overtaking on two-lane roads is easier if drivers use what is known as an overtaking assistant, a system which indicates when it is safe to overtake. This system prevents reckless drivers overtaking when it is not safe, and can also aid cautious drivers in overtaking slower vehicles.

Helpful Hair

"You are what you eat and drink - and that is recorded in your hair," says geochemist Thure Cerling, who led University of Utah research with ecologist Jim Ehleringer. The scientists developed a new crime-fighting tool by showing that human hair reveals the general location where a person drank water, helping police track past...
