Completely paralyzed man steps out in robotic exoskeleton

Working with a team of UCLA scientists, a man with protracted and complete paralysis has recovered sufficient voluntary control to take charge of a bionic exoskeleton and take many thousands of steps. Using a non-invasive spinal stimulation system that requires no surgery, this is claimed to be the first time that a person with such a comprehensive disability has been able to actively and voluntarily walk with such a device.

Mouth guard could continuously monitor diabetes, and more

We've already heard about an electronics-packing mouthguard that can be used to detect serious impacts to the head. Now, scientists at the University of California, San Diego have developed one that could provide continuous readings of users' health markers including lactate, cortisol and uric acid. It may be used to monitor the well-being of people such as diabetics, to track the performance of athletes, or to detect stress in soldiers.

Robotic needle can be steered through tissue

A robot-assisted system developed at the University of Twente promises to make medical procedures that use needles more precise. The system allows flexible needles to be steered in real time to their target, which negates issues with tissue and organs deforming from the contact pressure or from any unforeseen obstacles that lie between the needle and its target.

Vomiting machine projects better understanding of how stomach bugs spread

Norovirus is a nasty bug that brings about inflammation in the stomach and intestines leading to pain, nausea, diarrhea and sometimes even death. It affects around 20 million people per year in the US, but despite its rampant nature, questions remain over how exactly it is transmitted. To shed further light on how one of the world's most common pathogens spreads between humans, scientists have built a vomiting machine to study its behaviour when projected into the air.

Mice brainpower boosted with alteration of a single gene

"Ignorance is bliss," so the old saying goes, but who wouldn't give their brainpower a boost if they had the chance? By altering a single gene to inhibit the activity of an enzyme called phosphodiesterase (PDE4B), researchers have given mice the opportunity to see what an increase in intelligence is like. While many people would welcome such a treatment, the scientists say their research could lead to new treatments for those with cognitive disorders and age-related cognitive decline.

New material helps diabetic wounds heal faster

Because they often have weakened immune systems and/or blood flow restrictions, diabetics run a heightened risk of serious infection from even the smallest of open wounds. That's why a team of scientists from Egypt's Alexandria University have developed a means of getting those wounds to heal faster – silver-impregnated dressings.
