Tactra Penile Prosthesis Stands Up As Needed

Boston Scientific is releasing its new Tactra malleable penile prosthesis, a device that provides a new option for treating erectile dysfunction. It is designed to reproduce a natural erection thanks to a dual-layer silicone construction and Nitinol (a nickel titanium alloy), which is a shape-memory material that can easily transition between two d (Read more...)

Accurate Blood Pressure Measured from Video Selfies

As many medical technologies continue to miniaturize, the task of accurately measuring blood pressure still requires a cumbersome upper-arm cuff. Scientists at the University of Toronto and Hangzhou Normal University in China have now shown that it may be possible to use existing smartphones to measure blood pressure. Their approach relies on notic (Read more...)

Swiss Scientists Print World’s Smallest Stent

In rare cases, some children, often still in the womb, develop urethral strictures that make it difficult or impossible to empty the bladder. Typically, a surgical procedure is performed to remove the narrowed section of the urethra, with the open ends being sewed together. This is traumatic for the children and can be difficult for […]

Voltron Technology Lights Up Brain Activity in Real Time

While scientists have a variety of tools on hand to monitor and manipulate living brains, they still lack the ability to observe how large numbers of individual neurons operate in real time. Now, researchers at the Howard Hughes Medical Institute have developed a remarkable technology, published in the journal Science, that illuminates neurons just (Read more...)

Neurons Grow on Crosslinks of Carbon Nanotubes

Carbon nanotubes have a host of interesting properties. They are biocompatible and electrically conductive, so have been investigated as a possible material for growing nerve tissues. To make carbon nanotubes cooperate as desired, novel forms are required and researchers at SISSA (International School for Advanced Studies) and University of Trieste (Read more...)

CAVA Device Spots Nystagmus to Diagnose Dizziness

Dizziness is a common condition but its underlying causes can be very difficult to diagnose. It is usually unpredictable and doesn’t last very long, so by the time a patient presents to the physician everything checks out as normal. Detecting nystagmus (uncontrolled eye movements) is a pretty reliable way of diagnosing peripheral vestibular d (Read more...)
