Materials scientists from North Carolina State University, Raleigh, NC, and Qatar University have developed a new high-entropy metal alloy that, they say, has a higher strength-to-weight ratio than any other existing metal material. High-entropy alloys consist of five or more metals in roughly equal amounts....

A new preservation system that pumps cooled, oxygen-rich fluid into donor livers not only keeps the organs in excellent condition for as long as nine hours before transplantation, but also leads to dramatically better liver function and increases survival of recipients, according to a...

Stanford Biodesign fellows are testing two tiny devices that stimulate natural tear production. The technologies deliver micro-electrical pulses to the lacrimal gland.

Conventional neural probes are designed to record a single type of signaling, limiting the information that can be derived from the brain at any point in time. By producing complex multimodal fibers that could be less than the width of a hair, MIT researchers have created a system that could deliver optical...

Using electrophysiological measurements in the areas of the brain that are responsible for the planning and execution of hand movements, German Primate Center scientists predicted avariety of hand positions through the analysis of exact neural signals.

Researchers from North Carolina State University have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiography (EKG) or electromyography (EMG). The new sensor is as accurate as the “wet electrode” sensors used...

According to an FDA blog post, the FDA and regulatory agencies in Australia, Brazil, Canada, and Japan embarked in 2014 on a pilot called the Medical Device Single Audit Program (MDSAP). Its goal is to develop a process that allows a single audit, or inspection to ensure the medical device...

The FDA has developed a draft document to provide guidance to industry and FDA staff about the regulation of accessories to medical devices. This guidance is intended to clarify and modify the FDA’s policy concerning the classification of accessories and to discuss the application of that...
