"Smart Band-Aid" flexes, delivers medicine and more

The bandage is getting a major update for the 21st century, with the latest advances coming from engineers at MIT. A team there has developed a gel-like material that is sticky, stretchable and can be combined with sensors, lights and drug delivery systems to create a complete "smart wound dressing."Read More

Vitamin C-detecting sensor could assess eye injuries on the spot

Although any eye injury can be painful and upsetting, those that involve damage to the inside of the eye are the most serious. For people like battlefield medics or rural physicians, however, it can be difficult to judge the extent of such injuries without the resources of a hospital. That's why scientists from the University of Illinois have created OcuCheck – it's a portable sensor that assesses eye injuries based on the amount of vitamin C in the patient's tears.Read More

Exploding nanobubbles attack cancer cells from the inside out

No cancer treatment is straightforward, but attacking a tumor in the liver is an especially problematic process that normally involves surgery. A new technique may come to offer a less-invasive approach, however, by relying on nanobubbles that sneak cancer-fighting drugs into the tumor and can be popped to release their payload at just the right time.

First-ever ibuprofen patch delivers pain relief right where it's needed

One problem with orally-administered painkillers is that even though you may just have pain in a particular area, the medication affects your whole body. This both increases the chance of side effects, and limits the effect of the medication on that one area. Now, however, scientists at Britain's University of Warwick have developed a solution – they've created the world's first ibuprofen skin patch.Read More

Breakthrough in cell conversion could help with Parkinson's treatment

A team of University at Buffalo researchers has identified a key obstacle in the cell conversion process, the manipulation of which allows for much easier transitions between cell types. The breakthrough has big implications for the treatment of Parkinson's disease, with scientists able to create functional neurons to replace those damaged by the condition.Read More

Low-cost bioactive paper detects blood types in under a minute

Determining a blood type to ensure compatibility ahead of a transfusion isn't straightforward at the best of times, but in regions of the world where proper medical equipment is unavailable it is nigh on impossible. A new, bioactive piece of paper promises to change that, however, with the ability to analyze just a few drops of blood and identify somebody's blood group in as little as one minute.Read More

GM mice used in study to understand why some people can't feel pain

A new study from researchers at the UK's University College London (UCL) has examined a rare condition that makes people unable to feel pain, known as congenital insensitivity to pain (CIP). While previous projects have had little success in fully understanding the condition, the new effort represents a big breakthrough, pinpointing the key elements that cause it.Read More
