Martin Schubert - a Rensselaer Polytechnic Institute doctoral student in electrical, computer, and systems engineering - has developed the first polarized light emitting diode (LED), an innovation that could vastly improve LCD screens, conserve energy, and usher in the next generation of ultra-efficient LEDs. Schubert's...

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...

The detector controls and data conversion electronics components on the James Webb Space Telescope - collectively called a "SIDECAR" - have been miniaturized from a volume of about one cubic meter to a small integrated circuit. SIDECAR ASIC (System for Image Digitization, Enhancement, Control, And Retrieval Application...

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 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. Researcher Geertje Hegeman from the Delft...

"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...

A simple surface treatment technique developed by researchers at the National Institute of Standards and Technology (NIST), Penn State, and the University of Kentucky promises a low-cost method to produce arrays of organic electronic transistors on polymer sheets, paving the way for flexible displays and large...

Scientists at the University of Wisconsin at Madison have discovered a genetic pathway that may hold the key to understanding oxidative stress, the process that contributes to diseases such as Alzheimer's, heart disease, stroke, cancer, as well as aging. The finding could one day enable the manipulation of genes or...

VIA Technologies, Inc. (Taipei, Taiwan) has released the VIA NAB 7500 network appliance board for network security or gateway applications, including Firewall, VPN, UTM, Anti-Virus, and Intrusion Prevention System products.

HydroSmart is a new way to determine if you are adequately hydrated at any given time. It is a handheld, portable, simple- to-use device that requires a stream of urine, and the results are given almost instantaneously via a color-changing reagent. A color change corresponds to the specific gravity of the urine...

This technology features a uniquely designed suction head that eliminates problems typically experienced in alluvial diamond mining, mud, sewerage pumping, or dredging operations. This patented system offers a proven solution where no divers are required, and which can be operated...

A company seeks new non-oral delivery mechanisms for analgesics. Non-oral methods avoid the stomach and the intestine. These new mechanisms might be topical; that is, in contact with the outer layer of the skin. However, other nonoral mechanisms are open for consideration. Non-oral administration bypasses...

An organization seeks technology to enable foods to become crispy when heated in a home microwave oven. The outer surface should heat and become (or remain) crispy, while the interior body of the food should heat only as appropriate. The organization seeks materials, ingredients, or other...
