Cold Plasma to be Tested as Killer of Cancer Cells

Cold plasma is an unusual gaseous substance in which only the electrons are heated to thousands of degrees, with the rest of the material remaining at room temperature. Purdue University researchers have advanced this field and have helped to make it ready for clinical applications, since cold plasma has the ability to kill target cells […]

Stick-On Wearable Sweat Sensors to Monitor Exercise, Disease

The sweat excreted by our skin contains a number of metabolites and biomarkers that may be useful in managing disease, tracking athletic performance, and helping to identify health problems. Moreover, the amount of sweat that we produce can in itself be an important measure, but current sweat analysis techniques are very limited. Now, researchers a (Read more...)

Fully Flexible and Wireless Body Monitoring Sensors

Flexible body-worn sensors that conform to the skin have great potential for monitoring patient health, conducting long-term studies, and giving consumers a way to track their exercise and overall health. Although there have been flexible sticker-like body monitors developed in the past, they have all involved rigid electronic chips and batteries. (Read more...)

Exosuit Improves Metabolic Rate of Walking, Running

There have been a variety of exoskeletons and exosuits developed over the past decade or so that help with rehabilitation and assist workers in doing heavy labor. Improving walking and running abilities using a single system, though, has been a challenge because of differences in gait between walking and running. Now, researchers from Harvard and [ (Read more...)

Ekso Bionics Unveils EksoNR Neurorehabilitation Suit

Ekso Bionics, the California company that makes some of the most advanced exoskeletons out there, is releasing its latest neurorehabilitation suit, the EksoNR. Designed primarily to help people recovering from a stroke, the device recreates the natural movement of the legs and helps patients re-learn how to walk, sit, and do all the things they [&h (Read more...)

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...)
