Researchers have found that oxygen-containing free radicals aid rather than harm cell rege...

Researchers at the University of Manchester have found that Reactive Oxygen Species (ROS) – oxygen-containing free radicals that are commonly believed to be harmful to cells – actually play a vital role in the regeneration of the tails of tadpoles. The finding could have profound implications for the healing and regeneration of human tissue.  Read More

Using implants made from porous biocompatible materials, scientists have recently been successful in regrowing things such as teeth, tendons and heart tissue, plus bone and cartilage. The materials act as a sort of nanoscale three-dimensional scaffolding, to which lab-cultivated cells can be added, or that the recipient’s own cells can colonize. Now, a Spanish research team has used the same principle to grow new brain tissue – the technique could ultimately be used to treat victims of brain injuries or strokes.  Read More

Medicated dissolvable oral strips have been developed to treat minor burns inside the mout...

If you get a minor burn somewhere on the outside of your body, you can usually help dull the pain and promote healing by applying a piece of gauze and an ointment such as Polysporin. When you scald your tongue on a hot food or drink, however, you can’t exactly put a Band-Aid on it. That said, you may soon be able to apply a soothing medicated strip, instead.  Read More

Sutures have come along way from the days of silk and catgut, but now they’re poised to make their biggest change in 3,000 years. They’re getting smart. John Rogers, professor of materials science and engineering at the University of Illinois at Urbana-Champaign has invented a “smart” suture that contains ultrathin sensors that can detect when a wound is infected and may one day be able to actively promote healing as well.  Read More

ETH scientist have developed a specially contoured silicone that accelerates wound healing...

Even the smallest wound is potentially serious, so something as simple as a finger plaster and a little disinfectant can make the difference when it comes to preventing a nasty infection. But a dressing can do more than just keep out germs. That’s the idea behind work of the Laboratory of Thermodynamics in Emerging Technologies (ETH) in Zurich, Switzerland, where Prof. Dimos Poulikakos and his team of engineers and biologists are developing a new plaster that not only protects a wound from infection, it can also accelerate healing through the use of specially contoured silicone that promotes cell migration.  Read More

Swedish scientists have developed a nanocoating that allows the bone surrounding dental im...

The thought of having titanium screws implanted into one's jawbone is probably pretty unsettling for most of us, but for people who are getting individual teeth replaced, such implants are often required as attachment points for the artificial teeth. Once those screws are in place, patients often have to wait from about four to six months before they can chew solid food, as the bone surrounding the implant heals. Now, however, Swedish scientists have developed a new bioactive nanocoating for the screws, that promises to significantly decrease the required healing time.  Read More

A new material known as 'fracture putty' could be used to help broken bones heal much more...

Anyone who has ever broken a bone knows that while receiving the injury itself is quite unpleasant, being laid up for several weeks to even a few months afterwards is also no picnic. Help may be on the way, however. The U.S. Department of Defense is funding a study, to develop fast bone-healing treatments that could be used on soldiers, along with civilians and even animals. Already, scientists have gotten promising results in laboratory tests, using something they call “fracture putty.”  Read More

U.S. researchers have developed a nonsurgical technique to repair severed nerves in minute...

Professor George Bittner and his colleagues at the University of Texas at Austin Center for Neuroscience have developed a simple and inexpensive procedure to quickly repair severed peripheral nerves. The team took advantage of a mechanism similar to that which permits many invertebrates to regenerate and repair nerve damage. The new procedure, based on timely application of common chemicals to the severed nerve ends, could help patients to recover nearly full function in days or weeks.  Read More

The growth of these blood vessels was caused and directed by the microvascular stamp

In the not-too-distant future, wounds may be covered not just with regular bandages, but with special "microvascular stamps" that promote and direct the growth of new blood vessels. A team of scientists from the University of Illinois have already created such a dressing, which could ultimately have applications far beyond the healing of cuts.  Read More

A new understanding of the workings of a DNA-repairing enzyme could lead to medications th...

While there may be medications that help soothe sunburnt skin, when it comes to healing that skin ... well, we pretty much have to just wait for our bodies to do that on their own. Recent research conducted at Ohio State University, however, suggests that an actual healing treatment for sunburn may be on the way. It all comes down to some new understandings about an enzyme named photolyase.  Read More
