The wearable environmental and physiological sensing unit (WEPS) is a prototype of systems to be worn by emergency workers (e.g., firefighters and members of hazardous-material response teams) to increase their level of safety. The WEPS includes sensors that measure a few key physiological and...

The materials included in the collection of documents describe the research of the NASA Ames Fatigue Countermeasures Group (FCG), which examines the extent to which fatigue, sleep loss, and circadian disruption affect flight-crew performance. The group was formed in 1980 — in response to a...

Medical scientists at Johns Hopkins University (Baltimore, MD) have constructed the "PneuStep," a prototype pneumatic step motor that is the first of its kind. The motor was developed as part of a project for a robot that could operate precisely within the closed bore of high-intensity MRI equipment. The pneumatic nature of the...

Researchers at Massachusetts Institute of Technology (MIT) have created customizable hydrogel microparticles capable of identifying different biomolecules, disease monitoring, drug discovery, or genetic profiling. Each particle is equipped with a bar-coded ID and one or more probe regions that turn fluorescent when they detect...

The response of tumors to anticancer drugs has been observed in real-time, 3D images using technology developed at Purdue University. The new digital holographic imaging system uses a laser and a charged couple device (CCD) to see inside tumor cells. The instrument also may have applications in drug development and medical...

Researchers at the Dana-Farber Cancer Institute (Boston, MA) have found that the p53 protein, known to guard against cancer-causing DNA damage, provides an entirely different level of cancer protection: by prompting the skin to tan in response to ultraviolet light from the sun, p53 deters the development of melanoma skin cancer....

Medical researches at Information Society Technologies (Brussels, Belgium) are developing the IntelliDrug controlled drug delivery system, where medication is stored and released from an implanted tooth. The fake tooth is a micro-system comprising of a medication reservoir and release mechanism, a built-in intelligence, micro- sensors,...

Printable Biosensor for On-Site, Online Measurements -- Bioactive Hybrid Materials for Photonic Microsystems It allows samples to be analyzed on site within a few minutes by integrating biotechnology, information technology, electronics, physics, and chemistry to realize small and cost-effective bio-photonic microsystems....

University of Delaware researchers have developed an inexpensive, nonchlorine- based technology that can remove harmful microorganisms, including viruses, from drinking water. The patented technology incorporates highly reactive iron in the filtering process to deliver a chemical "knock-out punch" to a host of notorious...

Biologists at Yale University (New Haven, CT) are developing a process to trap viruses in habitats that force their extinction. Viruses are chemically lured into the wrong cells, thus preventing virus reproduction and alleviating disease. The research was conducted on phi-6 virus populations in environments containing different mixtures...

Brown University researchers are creating a technology that will allow doctors and scientists to see inside living humans and animals, and watch their bones move in 3D as they run, fly, jump, swim, and slither. This high-resolution, high-speed imaging system will contribute to better treatments for knee, shoulder, wrist, and back...

Equipment and a method for rapidly assaying solid surfaces for contamination by bacterial spores are undergoing development. The method would yield a total (nonviable plus viable) spore count of a surface within minutes and a viable-spore count in about one hour. In this method, spores...

Researchers at the University of Manchester (Manchester, UK) have devised an experimental method of virtual reality for the treatment of phantom limb pain (PLP) experienced by some amputees. Using headsets, data gloves, and other sensors, amputees used their remaining physical limbs to control the movements of a...

A laboratory method has been conceived to enable the enumeration of: Cultivable bacteria and bacterial spores that are, variously, airborne by themselves or carried by, parts of, or otherwise associated with, other airborne particles; and Spore-forming bacteria among all of the...

Architecture Adaptive Computing Environment (aCe) is a software system that includes a language, compiler, and run-time library for parallel computing. aCe was developed to enable programmers to write programs, more easily than was previously possible, for a variety of parallel computing architectures....

A proposed apparatus would apply controlled cyclic forces to both feet for the purpose of preventing the loss of bone density in a human subject whose bones are not subjected daily to the mechanical loads of normal activity in normal Earth gravitation. The apparatus was conceived for use by...

A proposed compact, portable instrument would sample micron-sized airborne particles, would discriminate between biological ones (e.g., bacteria) and nonbiological ones (e.g., dust particles), and would collect the detected biological particles for further analysis. The instrument is intended...
