Peptide-based nanogel accelerates healing of burn wounds

By - May 18, 2014 2 Pictures
Because second- and third-degree burns damage underlying layers of skin, they can take a long time to heal. Such extended healing periods are not only painful to the patient, but increase the risk of infection and scarring. While various medications are available to deal with pain and infection, there is currently no commercial treatment to speed up the rate of healing of burn wounds. Now researchers have developed a nanogel that could fill this hole. Read More

Smartsun wristband turns pink when it's time to make for the shade

By - May 8, 2014 1 Picture
Balancing a healthy amount of time in the sun while avoiding overexposure to its harmful UV rays can be a a difficult task. Indeed, the challenge of finding this happy medium has produced a bevy of of UV-detecting wristbands, such as the UVeBand and the UVA+Sunfriend. Smartsun is the latest to join the ranks of such devices, alerting users to dangerous levels of UV exposure by changing color from yellow to pink when it's time to head indoors. Read More

Stem cell-based treatment for baldness a step closer

By - February 4, 2014 2 Pictures
As one of the follically-challenged, any new breakthroughs in the area of hair regeneration will generally get my attention. When stem cells first started to gain widespread media attention I, no doubt like many others, thought a full head of hair was just around the corner. But despite numerous developments, years later my dome is still of the chrome variety. Providing the latest cause for cautious optimism, researchers have now developed a way to generate a large number number of hair-follicle-generating stem cells from adult cells. Read More

Sunfriend UV wristband encourages healthy sun exposure without sunscreen

By - December 1, 2013 3 Pictures
Most of us are aware of the dangers surrounding the amount of time we spend in the sun. Although we rely on exposure to sunlight to provide us with vitamin D, a lack of protection from harmful ultraviolet (UV) rays can lead to skin cancer. It can be a fine line between a healthy dose of sun and retreating indoors to coat ourselves in Aloe vera. The UVA+B Sunfriend aims to promote a healthy amount of sun exposure by alerting users when it is time to make for the shade. Read More

Wristify thermoelectric bracelet makes heating and cooling personal

By - October 24, 2013 2 Pictures
Most bracelets aren't likely to alter your temperature too much either way, but the Wristify isn't most bracelets. Developed by four MIT engineering students, the Wristify works on the principle that heating or cooling the skin on one part of the body can make the entire body feel warmer or colder. By creating a personal heating and cooling device, the Wristify team ultimately hopes to cut the amount of energy currently used to heat or cool entire buildings. Read More

MAP System continuously monitors patients for bedsores

By - August 15, 2013 5 Pictures
For long-term hospital patients or people who are otherwise bedridden, bedsores can be a major problem. Technically known as decubitus ulcers, they form when one area of the skin is subjected to too much prolonged pressure. In order to keep them from occurring, hospital staff regularly turn patients over in their beds. The MAP System is designed to aid those caregivers, by providing them with real-time imagery of the pressure points on the patient’s body. Read More

Unlocking the sunscreen code of marine life may offer complete UV protection

By - August 14, 2013 6 Pictures
The next generation of powerful sunscreens may have their roots in some unlikely sources – corals from the Great Barrier Reef and bacteria found in the Trondheim Fjord in Norway. When developed, these new sunscreens could offer protection across a wider band of ultraviolet (UV) radiation suspected to cause deadly forms of skin cancer, which current sunscreens don't protect against. The discoveries represent huge breakthroughs, made possible by harnessing the natural sunscreen abilities that these life forms have developed over millions of years to survive the harsh UV radiation in their respective environments.

Flexible sensor could lead to better artificial skin

By - July 9, 2013 2 Pictures
Using gold nanoparticles on top of a PVC substrate, researchers at the Technion-Israel Institute of Technology have built a new type of cheap, flexible sensor that simultaneously detects pressure, humidity and temperature with surprising accuracy. The sensor could be used to monitor cracks in bridges, create a better artificial skin to benefit amputees, or even to give robots that special "human touch." Read More

Scab-inspired wound dressing speeds healing

While you may think that standard bandages already serve as sort-of artificial scabs, the fact is that they mainly just compress and protect the wound – a scab, on the other hand, actually helps it heal. Now, however, scientists are working on a wound dressing that promotes healing in the same fashion as a scab. Read More
