Wideband Single-Crystal Transducer for Bone Characterization

The microgravity conditions of space travel result in unique physiological demands on the human body. In particular, the absence of the continual mechanical stresses on the skeletal system that are present on Earth cause the bones to decalcify. Trabecular structure decreases in...

Developing Physiologic Models for Emergency Medical Procedures Under Microgravity

Several technological enhancements have been made to METI’s commercial Emergency Care Simulator (ECS) with regard to how microgravity affects human physiology. The ECS uses both a softwareonly lung simulation, and an integrated mannequin lung that uses a physical...

Lithium Batteries for Medical Applications

The element lithium possesses fundamental properties that make it ideal for use as the anode in both primary and rechargeable batteries. Vendors have paired the popular lithium anode with a variety of cathode and electrolyte materials, resulting in the wide choice of different chemistries available...

‘Soft X-Ray’ Detector Could Improve Breast Cancer Imaging

While clear imaging is extremely important in diagnosing breast cancer from mammograms, there is also concern about exposing the patient to too much radiation from repeated X-rays. But that may soon change, says Krishna Mandal, an associate professor of electrical engineering at the...

VA Developing New Heat- Enhanced Pulse Ox Device

Pulse oximetry has gained widespread clinical acceptance as a standard patient vital sign measurement because it can give clinicians an early warning of low arterial blood oxygen saturation levels, or hypoxemia. Conventional pulse oximetry is subject to technological limitations that reduce its...

Lightening the Load of Recovery

Ask the Denver attorney whose legs were smashed in a car accident. Ask the veterans rehabilitating from injuries sustained while defending the nation. Ask NBA star Blake Griffin, or NFL safety Jim Leonhard, both of whom endured leg injuries playing their sports. Ask U.S. soccer pro Charlie Davies, who returned to...

Extreme Ionizing-Radiation-Resistant Bacterium

There is a growing concern that desiccation and extreme radiation-resistant, non-spore-forming microorganisms associated with spacecraft surfaces can withstand space environmental conditions and subsequent proliferation on another solar body. Such forward contamination would jeopardize future life...

Fluorescence-Activated Cell Sorting of Live Versus Dead Bacterial Cells and Spores

This innovation is a coupled fluorescence-activated cell sorting (FACS) and fluorescent staining technology for purifying (removing cells from sampling matrices), separating (based on size, density, morphology, and live versus dead), and concentrating cells...

Nonhazardous Urine Pretreatment Method

A method combines solid phase acidification with two non-toxic biocides to prevent ammonia volatilization and microbial proliferation. The safe, nonoxidizing biocide combination consists of a quaternary amine and a food preservative. This combination has exhibited excellent stabilization of both acidified...

Method and Apparatus for Automated Isolation of Nucleic Acids from Small Cell Samples

RNA isolation is a ubiquitous need, driven by current emphasis on microarrays 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...

Flexible Sensors Offer View into Epileptic Seizures

Tapping into the human brain to understand its functions in daily life — as well as its malfunctions in illness — has long been a challenge for researchers. Mapping brain activity requires unwieldy, invasive arrays of electrodes and sensors that can damage tissue while only reading activity...
