Glenn Research Center (Cleveland, OH) has designed a power supply for a cordless drill in which ultracapacitors, rather than batteries, are used to store energy. Whereas charging of batteries usually takes hours, ultracapacitors can be charged in seconds. Read more here.

The Biomedical Center in Moscow has produced a vaccine that induces cytotoxic lymphocyte (CTL) clones and enables them to recognize and selectively kill Listeria- infected cells. As the lifetime of CTL clones is very long (three-seven years or more), the formulation could be used for both prophylaxis and treatment of Listeriosis,...

Cars already automatically lock doors when they sense motion and turn on warning lights if they detect engine problems. But they are about to get a lot smarter. A research team at Sandia National Laboratories (Albuquerque, NM) is designing cars capable of analyzing human behavior. Future models may, for example, deduce from your driving...

Glowing firebrands (burning wood pieces) make for a warm evening in front of the fireplace, but for homeowners in high fire-risk areas, windborne fire material can be a nightmare. The National Institute of Standards and Technology (NIST) has built a firebrand generator to study how firebrands ignite structures. It generates...

A company is seeking an absorbent pad capable of being loaded with a terpanol, which, when saturated, will allow the free flow of air or other gases through its structure. The pad can be made of any thickness or material, and can be used in household, office, and industrial applications. Find out more here.

Scientists from the University of Pennsylvania have developed nanowires that can store computer data for 100,000 years and retrieve the data 1,000 times faster than existing portable memory devices such as Flash and micro-drives. The self-assembling nanowire is made of germanium antimony telluride, a phase-changing material that...

The MDrive 14Plus Motion Control system from Intelligent Motion Systems (Marlborough, CT) combines the motor, driver, controller, and encoder in one system using a NEMA size 14 brushless 1.8-degree motor. It measures 1.9 x 1.4 x 2.0" and includes a programmable controller and programming instruction set. Communication is via RS-422/485...

Researchers at NASA's Johnson Space Center in Houston, TX, have developed a diaphragm pump driven by a piezoelectric actuator. The pump is a prototype of a lightweight pump for circulating cooling liquids in protective garments, high-power electronic circuits, and other medical applications. The pump contains no sliding seals or...

An unobtrusive sensor that collects and immediately transmits data from the human body could boost athletic performance. Developed at Imperial College London with funding from the Engineering and Physical Sciences Research Council (EPSRC) in the UK, the new sensor also has potential in healthcare. The sensor is the size of...

Each month, NTB highlights tech briefs related to a particular area of technology in a special section called Technology Focus. Here are some of the technologies featured in the September issue focus on Composites & Coatings. - Rapid Fabrication of Carbide Matrix/Carbon Fiber Composites Researchers at NASAís Marshall...

An epoxy coating for metals is a highly fluorinated, cross-linked polymer containing finely ground Teflon-like particles that impart permanent lubricity. The coated metal surfaces prepared with this technology have good corrosion resistance and durability. They are useful as seat rails, bushings, guide tracks, or any place where a...

Terrorists and extremists use the Internet to recruit new members, spread propaganda, and plan attacks. The size and scope of these dark corners of the Web are vast and disturbing. A team of computational scientists at the Artificial Intelligence Lab at the University of Arizona is using new approaches to track terrorists' moves...

The X PRIZE Foundation and Google announced the Google Lunar X PRIZE, a robotic race to the Moon to win a $30 million prize. Private companies from around the world will compete to land a privately funded robotic rover on the Moon that is capable of completing several mission objectives, including roaming the lunar surface for at least...

A system of electronic hardware and software that noninvasively tracks the direction of a person's gaze in real time has been developed by researchers at NASA's Jet Propulsion Laboratory in Pasadena, CA. The system illuminates the eye with a low-power infrared LED; acquires video images of the pupil, iris, and cornea in the reflected...

Doctors rely on a dwindling arsenal of drugs to fight bacterial infections as the bugs keep finding ways to survive. These "superbugs" may be brought to their knees with the discovery by Boston University biomedical engineers of a previously unknown chain of events occurring in bacteria when they are fed antibiotics. The three...

A company seeks technology for casting ophthalmic lenses with a refractive index of at least 1.67, and Abbe of at least 37. Operating parameters would be to cast lenses at ambient conditions with low odor. Thermal or radiation cure is acceptable for polymerization of lens material, with radiation cure preferred. Click here to...

Scientists have identified two proteins that pair up at the precise location in the ear where sound vibrations are turned into electrical signals. The finding may eventually help researchers develop more precise treatments for hearing loss, a condition that affects more than 32 million people in the United States. When a car horn...
