UV-measuring wrist band lets you know when to reapply sunscreen

If you spend much time outdoors in the summer, then you doubtless know how important it is to wear sunscreen. That said, you probably also know that just applying it once before you first go outside isn’t good enough – for sufficient protection from the sun’s ultraviolet rays, periodic reapplications are also necessary. The UVeBand is a new wearable device, that’s designed to let you know when it’s time for those reapplications. Read More

Filler makes old skin cells act young again

The latest development in the quest for eternal youth concerns that most visible sign of aging – the skin. Scientists at the University of Michigan (U-M) have found that it might be possible to slow the decline of aging tissue by focusing not on the cells but on the stuff that surrounds those cells. By adding more filler to the fiber-filled area around the cells, they were able to make the skin cells of senior citizens act like younger cells again. Read More

Tattoo-based medical sensor puts a happy face on detecting metabolic problems

Next time you see an adult with a stick-on tattoo, don’t laugh – that person might have a metabolic problem, or they could be a high-performing athlete who’s getting their training schedule fine-tuned. No, really. A team lead by Dr. Joseph Wang at the University of California, San Diego, has created a thin, flexible metabolic sensor that is applied to the skin ... and it takes the form of a smiley-face tattoo.

MIT researchers develop painless medical tape for newborns

Pulling off a finger plaster is one of life’s little trials that can reveal a lot about a person. Do it fast or do it slow, it still hurts like heck and there’s no pretending that it didn't. For an adult, it’s an instant of pain, but for a newborn it can mean injury or even permanent scarring. In order to prevent this, a team of researchers are developing a new medical tape that can be pulled off safely without tearing delicate infant skin. Read More

Laser-based system promises to take the "ouch" out of injections

Nobody likes getting their shots, but whether childhood immunization, annual flu vaccination, or whatever else, we're required to undergo the uncomfortable sensation of needle piercing skin multiple times throughout our lives. However, a new laser-based system promises to take the “ouch” out of injections by delivering shots as painlessly as being struck by a puff of air. Read More

Body-heat-activated patch could pump medication through the skin

Transdermal patches are currently used for the controlled release of medication, as long as that medication is made up of molecules that are small enough to be absorbed through the wearer’s skin. For solutions with larger molecules, scientists are looking into the use of patches incorporating arrays of skin-piercing microneedles. In many of these cases, however, the patches would require some sort of tiny battery-operated pump, to push the medication through the needles. Now, researchers from Indiana’s Purdue University have developed what could be an alternative – microneedle patches that use the wearer’s own body heat to deliver the drugs. Read More

Disney Research's gloveless REVEL system adds virtual textures to physical objects

Having long been successful with "talkies," Disney has developed technology that could allow the creation of "feelies." While designed more for touchscreens than the silver screen, the REVEL system developed at Disney Research uses reverse electrovibration to bring computerized control over the sense of touch, thereby allowing programmers to change the feel of real-world surfaces and objects without requiring users to wear special gloves or use force-feedback devices.

Spray-on skin speeds healing of venous leg ulcers

According the UK’s National Health Service, one person in 50 over the age of 80 will develop venous leg ulcers. The ulcers occur when high blood pressure in the veins of the legs causes damage to the adjacent skin, ultimately resulting in the breakdown of that tissue. While the ulcers can be quite resistant to treatment, a team of scientists is now reporting success in using a sort of “spray-on skin” to heal them. Read More

Neuronal stem cells generated directy from skin cells

Researchers at the Max Planck Institute for Molecular Biomedicine in Münster, Germany, have broken new ground by reprogramming skin cells from mice into neurons without regressing the cells through a pluripotent stage. The skin cells were reprogrammed directly into multipotent neuronal stem cells - that is, into cells which could only turn into new neurons. This procedure avoids the significant risk that pluripotent stem cells, which can grow into any type of tissue, may accidentally form tumors rather than the desired replacement tissue. Read More
