A team of engineers at the University of South Carolina (Columbia, SC) have built a laboratory-scale device that sensitively detects what are called “soft X-rays” that they say offers tremendous potential in breast cancer detection and treatment. There’s nothing available on the market that...

Pulse oximetry is widely accepted as a standard measurement of a patient’s oxygen saturation and heart rate because it can give clinicians an early warning of low arterial oxygen saturation levels. But low body temperature and low blood perfusion can cause conventional pulse oximeters to report inaccurate...

Singapore's Health Sciences Authority (HSA), the country’s medical device market regulator, has implemented new rules in order to expedite market access for lower-risk medical devices. The rules will exempt all Class A medical devices (except sterile Class A products) from HSA registration...

On Monday, Aug. 6, University of Southern California Computer Science Professor Jernej Barbič released the world's most comprehensive library of 3D deformable modeling software for free open source download. The package, called Vega, allows users to simulate and move complex objects, bending,...

A team of researchers at the Georgia Institute of Technology has used complex computational models to design swimming micro-robots that carry cargo and navigate in response to stimuli such as light.The simple micro-swimmers could rely on volume changes in unique materials known as hydrogels to move tiny flaps that...

On Sunday, NASA's Curiosity rover successfully landed on Mars. The orbiter ushers in a new era of exploration that, some say, could turn up evidence that Mars once had the necessary ingredients for life — or might even still harbor life today. The land rover also creates new possibilities for human exploration of...

Scientists at Clemson University (Clemson, SC) have designed and built a knee simulator on which specimens from cadavers can be mounted to study the effects of different unicompartmental knee arthroplasty (UKA) alignment and ligament configurations on movement, as well as contact pressure distributions...

Thousands of veterans return to the U.S. with limb amputations, and for many, standard prosthetics are not an option due to skin issues or short remaining-limb length. These amputees require something other than the typical socket-type attachment systems. Researchers and surgeons from the University of Utah and...

Researchers at the Harvard School of Engineering and Applied Sciences (SEAS), collaborating with the Weizmann Institute of Science in Israel, have now demonstrated a drastically new way of achieving negative refraction in a metamaterial.The primary advantages of the new technology...

A team of researchers at MIT has discovered a way to create wrinkled surfaces with precise sizes and patterns. This basic method, they say, could be harnessed for a wide variety of useful structures: microfluidic systems for biological research, sensing, and diagnostics; new photonic devices that can control...

Humans have launched 40 spacecraft to Mars, and the latest machine to make the effort is NASA's Mars Science Laboratory. If the Mars Science Laboratory lands safely next week, instruments will begin to analyze the soil, air, and rocks for life, past or present. While some say that the costs are not worth the...
