Implantable device aids weight loss
New battery-free, easily implantable weight-loss devices developed by engineers could offer a promising new weapon for battling the bulge.
It's not a shock: Better bandage promotes powerful healing
A new, low-cost wound dressing could dramatically speed up healing in a surprising way. The method leverages energy generated from a patient's own body motions to apply gentle electrical pulses at the site of an injury.
Explaining the plummeting cost of solar power
The dramatic drop in the cost of solar photovoltaic modules, which has fallen by 99 percent over the last four decades, is often touted as a major success story for renewable energy technology. But one question has never been fully addressed: What exactly accounts for that stunning drop?
New material, manufacturing process, uses sun's heat for cheaper power
Researchers have developed a new material and manufacturing process that would make one way to use solar power - as heat energy - more efficient in generating electricity.
New fuel cell concept
In a new approach, inspired by biology a university team has designed a fuel cell using cheaper materials and an organic compound that shuttles electrons and protons.
Kids connect with robot reading partners
Kids learn better with a friend. They're more enthusiastic and understand more if they dig into a subject with a companion. But what if that companion is artificial?
Wearable device measures tendon tension
For athletes and weekend warriors alike, returning from a tendon injury too soon often ensures a trip right back to physical therapy. However, a new technology developed by engineers could one day help tell whether your tendons are ready for action.
Artificial intelligence can help you protect your personal data
It's a safe bet that some of the websites and apps you use collect and subsequently sell your personal data. But how can you know which ones? A researcher has led the development of a program that can answer that question in just a few seconds, thanks to artificial intelligence.
