Researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) in Tennessee say they have developed a new type of battery chemistry aimed at producing batteries that last longer than previously thought possible.

A team of engineering researchers at the University of Arkansas, Fayetteville, say they have developed a wireless health-monitoring system that could continuously monitor an entire team of football players for physiological signs of concussion. The system includes a dry, textile-based nanosensor and accompanying...

A droplet of clear liquid can bend light, acting as a lens. Now, by exploiting this well-known phenomenon, Australian researchers have developed a new process to create inexpensive high quality lenses that will cost less than a penny apiece.

A team of researchers from Cornell University, Ithaca, NY, and Brookhaven National Laboratory, Upton, NY, have demonstrated how to switch a particular transition metal oxide, a lanthanum nickelate (LaNiO3), from a metal to an insulator by making the material less than a nanometer thick.

A team of researchers at the University of Pittsburgh have developed a tiny microchip that, they say, may save joint implants before they’re overcome by infection. This chip, which is engineered to detect pH levels in the body, can alert doctors to encroaching bacterial infection, which causes acidosis, a...

Using a single drop of blood, a team of engineers at the University of Wisconsin-Madison has developed what they say is a faster, cheaper, and more accurate tool for diagnosing even mild cases of asthma.

An international team of engineers from Penn state University, University Park, PA, and King Abdullah University of Science and Technology, Saudi Arabia, have discovered that saliva-powered micro-sized microbial fuel cells can produce minute amounts of energy—enough to run on-chip applications, they say. This...

A team of researchers at Johns Hopkins Medicine, Baltimore, has designed a computerized imaging process to make minimally invasive surgery more accurate and streamlined using equipment already common in the operating room.

Physicians at the Medical College of Georgia and Georgia Regents University, Augusta, say that the intra-aortic balloon pump, one of the most frequently used mechanical circulatory assist devices in the world may have untapped potential. One of its many uses is helping ensure adequate oxygen...

Researchers at the University of Illinois, Urbana-Champaign, led by Professor John Rogers, PhD, are taking on the challenge of health and sustainability issues simultaneously by developing a vast toolbox of materials—from magnesium and silicon to silk and even rice paper—to make biodegradable...

A team of researchers at the Stanford University School of Medicine, Stanford, CA, has developed two inexpensive adapters that enable a smartphone to capture high-quality images of the front and back of the eye. The adapters can allow anyone with minimal training to take a picture of the eye and share it securely...

A team of scientists at the University of Cincinnati, OH, says that an electrical stimulus can promote the growth of blood vessels and help to speed healing in diabetic ulcers and other hard-to-heal chronic wounds. Their research examines the best stimulus parameters, such as frequency and magnitude,...

A new technique to purify blood uses a nanofiber mesh, which could be useful as a cheap, wearable alternative to kidney dialysis, say a team of researchers at the International Center for Materials Nanoarchitectonics, National Institute for Materials Science in Ibaraki, Japan. The mesh could be incorporated...

Using an inexpensive 3D printer, biomedical engineers at Washington University in St. Louis, MO, say that they have developed a custom-fitted, implantable device with embedded sensors that could treat cardiac disorders.

A team of scientists from Nanjing University in China and the University of Illinois at Urbana-Champaign is exploring the use of metamaterials to create devices that manipulate sound in versatile and unprecedented ways. This was reported in the journal, Applied Physics Letters.

Engineers at the University of Wisconsin-Milwaukee first discovered a new way to propagate multiple beams of light through a single strand of optical fiber. Now, they say that their unique fiber architecture can transmit images of comparable or better quality than commercial endoscopy imaging...

Cochlear implants, which electrically stimulate the auditory nerve, grant some hearing to those who might otherwise be deaf. One drawback has been that the devices require that a transmitter be affixed externally to the skull, with a wire snaking down to a joint microphone and power source that looks like...
