Focused waves of ultrasound have been used to release insulin from reservoirs in the skin

There could be hope for diabetics who are tired of giving themselves insulin injections on a daily basis. Researchers at North Carolina State University and the University of North Carolina at Chapel Hill are developing a system in which a single injection of nanoparticles could deliver insulin internally for days at a time – with a little help from pulses of ultrasound.  Read More

The Hövding is an airbag for cyclists which inflates in under 0.1 seconds to protect your ...

We first covered the Hövding airbag collar in 2010 when it was originally shown off to the world by its inventors, industrial designers Anna Haupt and Terese Alstin. At the time it was available to pre-order but it has now officially gone on sale.  Read More

A new algorithm could help hearing aids separate speech from background noise (Photo: Shut...

Despite some advances that have been made in the field, one of the continuing problems with hearing aids is the fact that they amplify background sound along with peoples' voices. While our brains are reasonably good at distinguishing between speech and distracting ambient noise, hearing aid users get the noise and the voice presented to them in one often-incomprehensible package. Researchers at The Ohio State University, however, may have a solution. They've developed a noise-filtering algorithm that's been shown to improve test subjects' recognition of spoken words by up to 90 percent.  Read More

Help could be on the way for people who don't have enough bone to support dental implants, who are missing bone due to a birth defect, or who have suffered bone-damaging injuries. Scientists at the University of Iowa have created an implantable collagen patch seeded with particles containing synthetic DNA, that instructs the patient's own cells to produce the protein that leads to bone growth.  Read More

A new study has found a link between higher chocolate consumption and lower body fat level...

In what may be the best news for chocoholics since scientists at the University of Cambridge found that higher chocolate consumption was associated with a significant reduction in cardiovascular disease, diabetes and stroke, researchers at the University of Granada are reporting that it's also associated with lower levels of total fat deposits – in the bodies of adolescents at least.  Read More

Jake Merrell field-testing his Xonano smart foam

As any coach or sports medicine expert will tell you, when an athlete receives a blow to the head, their saying that they feel OK doesn't mean that they don't have a concussion. Particularly in sports like football, it's important to have an objective method of measuring just how much of a hit a player's noggin has taken. While some people have developed impact sensors that can be attached to players' helmets, a student at Utah's Brigham Young University has devised something less obtrusive – impact-sensing helmet-lining foam.  Read More

The scene at Ontario's Rod and Gun Club, where Garrison Bespoke's new bulletproof three-pi...

In a scene only dreamt of by most people, the employees of Garrison Bespoke, an upscale Toronto tailor, lined up and waited their turn to stab their boss, Michael Nguyen, with a hunting knife. Mr. Nguyen emerged from the experience unscathed, thanks to a remarkable bulletproof business suit that has just been revealed to the public.  Read More

According to researchers, a multi-photon laser technique can be used to detect protein agg...

It is generally believed that aggregations of proteins are responsible for brain disorders such as Alzheimer's, Parkinson's and Creutzfeldt-Jakob disease. However, the difficulty has been in detecting the aggregates responsible and removing them from the brain. Researchers at Chalmers University of Technology in Sweden and Polish Wroclaw University of Technology have found a potential solution using lasers.  Read More

The 5aver combines LED lantern and triple-filter mask

The thought of getting caught in a building fire is terrifying. Flames raging, smoke obscuring your vision and making it difficult to breathe, infrastructure crumbling, and you're trying desperately to remain calm and get out. The 5aver won't douse the flames, but the grab-and-go combination of lantern, alarm and mask is designed to help you find your way to safety in a hurry.  Read More

Researchers have created new human hairs using dermal papilla cells found inside the base ...

Current hair transplantation techniques essentially rob Peter to pay Paul, redistributing hair, usually from the back of the head, to the balding area. However, according to Angela M. Christiano from Columbia University Medical Center, about 90 percent of women with hair loss are not strong candidates for hair transplantation surgery because of insufficient donor hair. A new technique developed by Dr Christiano and colleagues that generates new human hair growth from a patient's own cells could make transplantation feasible for such women, as well as men in the early stages of baldness.  Read More
