Zinc, an essential nutrient, is found in every tissue in the body. The vast majority of the metal ion is tightly bound to proteins, helping them to perform biological reactions. Tiny amounts of zinc, however, are only loosely bound, or "mobile," and thought to be critical for proper function in organs such as the brain, pancreas, and prostate gland.
The winners of the 2013 Nobel Prizes will collect their $1.2 million awards Tuesday at ceremonies in Stockholm and Oslo. Here's a look at the laureates and their achievements: ECONOMICS Three Americans were honored for developing new methods to study trends in asset markets,
Germany's express delivery and mail company Deutsche Post DHL is testing a drone that could be used to deliver urgently needed goods to hard-to-reach places. The small pilotless helicopter was to fly a package of medicine Monday from a pharmacy in the town of Bonn to the company's headquarters on the other side of the Rhine River. The aircraft can carry up to 3 kilograms (6.6 pounds).

SL Power Electronics announces its MB60S single-output, convection-cooled, wide temperature range power supply that provides 60 watts of power in an ultra-compact 2” x 3” x 1.0” package. Joining SL Power’s line of high-density open frame AC/DC medical-grade power supplies, the MB60S is approved to the highest safety standards....
In the buzzword story of the year, researchers at the University of the West of England created a 3D-printed heart robot heart that runs on urine. That’s right, a printed organ that pumps pee through a robot. This hot topic cornucopia was actually the result of a theory that urine was capable of making electricity.
A tiny capsule that can carry out a chemical analysis of the contents of one's stomach could identify the presence of so-called "occult" blood at very low levels. The data is automatically broadcast to an external monitoring device for detection of early stage stomach cancer by one's physician.
STMicroelectronics announced that its 5.1 mega-pixel camera module and low-power digital image processor are being used in the revolutionary OrCam camera, a small device that clips on to eyeglasses and dramatically improves the mobility and ability of visually-impaired people to “read” signs, packaging and publications.
After a diving accident left Jason Disanto paralyzed from the neck down in 2009, he had to learn how to navigate life from a powered wheelchair, which he controls with a sip-and-puff system. Users sip or puff air into a straw mounted on their wheelchair to execute four basic commands that drive the chair.
Using a novel stroke rehabilitation device that converts an individual's thoughts to electrical impulses to move upper extremities, stroke patients reported improvements in their motor function and ability to perform activities of daily living. Results of the study were presented today at the annual meeting of the Radiological Society of North America (RSNA).
Using a special type of magnetic resonance imaging (MRI), researchers have found that soldiers who suffered mild traumatic brain injury (MTBI) induced by blast exposure exhibit long-term brain differences, according to a study being presented today at the annual meeting of the Radiological Society of North America (RSNA).
Sex may in fact be one of the secrets to good health, youth and a longer life – at least for fruit flies – suggests a new University of Michigan study that appears in the journal Science. Male fruit flies that perceived sexual pheromones of their female counterparts – without the opportunity to mate – experienced rapid decreases in fat stores, resistance to starvation and more stress. The sexually frustrated flies lived shorter lives.
Texas Instruments introduced five new next-generation power management integrated circuits that acquire and manage microwatts (µW) to milliwatts (mW) of power harvested from light, heat or mechanical energy sources. The bq25570, bq25505, TPS62740, TPS62737 and TPS62736 maintain
Allegro MicroSystems, LLC announces the release of three new switch-mode power supplies. The C, HWB and SWF series have been designed with a user-configurability feature to prevent customers from replacing the entire set of power supplies making it much easier to change specifications.
Advanced Power Solutions (APS) announces the release of the APS250EMG series of medical approved desktop switching power supplies with up 94% efficiency and <0.5W No Load Power Consumption for compliance to Level V standards. The APS250EMG series consists of 3 standard models offering single outputs of 12V @ 20A / 24V @ 12 / 48v @ 6A output power....
The September 2013 issue of ECN deals with Medical Electronics. Managing Editor Kasey Panetta focuses on “fighting an invisible enemy” with UV robots in hospitals, and in the Editor’s View, Executive Editor Chris Warner discusses the controversial practice of license plate scanning.
Computer engineers and hearing scientists at The Ohio State University have made a potential breakthrough in solving a 50-year-old problem in hearing technology: how to help the hearing-impaired understand speech in the midst of background noise. They describe how they used the latest developments in neural networks...
Linear Technology Corporation announces the LT8302, a monolithic flyback regulator that significantly simplifies the design of isolated DC/DC converters. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no opto-isolator or third winding for regulation.
Ultra-miniature detect switches are playing a significant role in a number of applications today. The miniaturization of key components, including switches, has enabled the continued trend towards end-products getting smaller and smaller.
What if certain patients could get a bionic pick-up without undergoing the pain and lengthy recovery of surgery? University of Cincinnati researchers are working on just that idea, with the start of an exoskeleton to support people who – through age or injury – are limited in their movement.
Johns Hopkins engineers and cardiology experts have teamed up to develop a fingernail-sized biosensor that could alert doctors when serious brain injury occurs during heart surgery. By doing so, the device could help doctors devise new ways to minimize brain damage or begin treatment more quickly.
Recent advances in robotics technology make it possible to create prosthetics that can duplicate the natural movement of human legs. This capability promises to dramatically improve the mobility of lower-limb amputees, allowing them to negotiate stairs and slopes and uneven ground, significantly reducing their risk of falling as well as reducing stress on the rest of their bodies.
“Not to worry, I’ll just print another hand.” This statement would belong in a work of fiction a few years ago, but today, it is reality for those missing fingers or limbs. Prosthetics have come a long way from the archaic image of a pirate hobbling around his ship on a wooden peg leg.
Obama administration officials are facing mounting questions about whether they cut corners on security testing while rushing to meet a self-imposed deadline to launch online health insurance markets. Documents show that the part of HealthCare.gov that consumers interact with directly received only a temporary six-month security certification...
