A research team at the Georgia Tech Research Institute (GTRI) has developed a small electronic sensing device that can alert users wirelessly to the presence of chemical vapors in the atmosphere. The technology, which could be manufactured using familiar aerosol-jet printing techniques, is aimed at myriad...

A software application detects the heart rate of an individual by using a real-time video stream from a common camera connected to their computer. This involves no contact between the user and the camera, or calibration between individual users. NASA’s...

In 1974, Sherwood Rowland and Mario Molina discovered that chlorofluorocarbons (CFCs) were depleting the ozone layer, and in 1995, they received the Nobel Prize in Chemistry for this work. In response, the United Nations Environment Programme called an international conference to discuss the issue. Shortly...

The microbead packing is the critical element required in the success of onchip microfabrication of critical microfluidic components for in-situ analysis and detection of chiral amino acids. In order for microliquid chromatography to occur, there must be a stationary phase...

RNA isolation is a ubiquitous need, driven by current emphasis on micro-arrays and miniaturization. With commercial systems requiring 100,000 to 1,000,000 cells for successful isolation, there is a growing need for a small-footprint, easy-to-use device that can...

Based on previously reported procedures for permeabilizing vegetative bacterial cells, and numerous trial-and-error attempts with bacterial endospores, a protocol was developed for effectively permeabilizing bacterial spores, which facilitated the...

This innovation is a system that augments human vision through a technique called “Sensing Super-position” using a Visual Instrument Sensory Organ Replacement (VISOR) device. The VISOR device translates visual and other sensors (i.e., thermal) into sounds to enable very difficult sensing tasks.

Most single-stranded RNA (ssRNA) viruses mutate rapidly to generate a large number of strains with highly divergent capsid sequences. Determining the capsid residues or nucleotides that uniquely characterize these strains is critical in understanding the strain diversity of these viruses. RECOVIR (an acronym...

The 2013 Create the Future Design Contest — sponsored by COMSOL, SAE International, and Tech Briefs Media Group (publishers of NASA Tech Briefs) — recognized innovation in product design in eight categories: Aerospace & Defense (new this year), Consumer Products, Electronics, Machinery & Equipment,...

The ability to stabilize and treat patients on exploration missions will depend on access to needed consumables. Intravenous (IV) fluids have been identified as required consumables. A review of the Space Medicine Exploration Medical Condition List (SMEMCL) lists over 400 medical conditions that could present and...

This method uses a photoaffinity label that recognizes DNA and can be used to distinguish populations of bacterial cells from bacterial spores without the use of heat shocking during conventional culture, and live from dead bacterial spores using...

There are eight herpes viruses that infect humans, causing a wide range of diseases resulting in considerable morbidity and associated costs. Varicella zoster virus (VZV) is a human herpes virus that causes chickenpox in children and shingles in adults. Approximately 1,000,000 new cases of...

New York, NY – ChemoPatch, a low-cost, disposable, electronic patch-based cancer chemotherapy device designed to be simple, automated, and easy-to-use by cancer patients outside of the hospital, has been awarded the grand prize of $20,000 in the 2013...

University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with researcher Rajesh Rao able to send a brain signal via the Internet to control the hand motions of fellow researcher Andrea Stocco.

Astronauts lose 1.0 to 1.5% of their bone mass per month on long-duration spaceflights. NASA wishes to monitor the bone loss onboard spacecraft to develop nutritional and exercise countermeasures, and make adjustments during long space missions. On Earth, the...
