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

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.  Read More

The medical tape is designed to peel off while leaving the adhesive behind

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

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

New technology may allow transdermal patches to pump out medication by harnessing the wear...

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

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.  Read More

A solution containing skin cells and proteins has been shown to speed the healing of venou...

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

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

Graphics researcher Jorge Jimenez has cracked the problem of rendering what he calls "ultra realistic skin" in real-time with consumer-level computer and graphics hardware. It's a breakthrough made possible by the process of separable subsurface scattering (SSS) which quickly renders the translucent properties of skin and its effect on light in two post-processing passes. The code is based wholly on original research using DirectX 10. Jimenez describes the achievement as the result of hours of "research, desperation, excitement, happiness, pride, sadness and extreme dedication."  Read More

Third-degree burns typically require very complex treatment, and leave nasty scars once they've healed. Researchers at Johns Hopkins University, however, are reporting success at treating such burns on lab mice, using a new type of hydrogel that grows new skin (as opposed to scar tissue) over burn sites. The gel contains no drugs or biological components - it's made mainly from water and dissolved dextran, which is a sugar-like polymer.  Read More
