Scientists decode newts' ability to regenerate limbs

Adult newts are the envy of the animal kingdom when it comes to replacing missing tissue. Amputated legs, arms or tails, there's hardly repair job too big for this animal's remarkable regenerative abilities. For the first time, scientists have pinpointed the mechanism used by the amphibian to regrow missing body parts, a development they say will offer clues to muscle regeneration in mammals.Read More

Wounds may be treated using ... frog foam?

When the tiny Tungara frog lays its eggs, it also secretes a protein cocktail that it beats into a foam using its back legs. Surrounding the eggs, that foam protects them from predators, germs and environmental stress. As it turns out, a synthetic version of the substance may also one day have another use – delivering medication to serious skin wounds.Read More

Modified maggots fast-track wound healing

It might be a little hard to stomach, but using maggots to clean up wounds is a technique that has been in use for centuries. By selectively devouring dead flesh and leaving healthy tissue intact, these loathsome larvae have offered a cheap way of treating wounds, but not necessarily a quicker one. Now scientists are looking to hasten the healing process by genetically modifying maggots to produce a human growth factor while they go about their business.Read More

Infection-fighting bandages may help treat serious burns

When a burn wound is healing, it's usually highly susceptible to infection, and bandages often make the situation worse, acting as breeding grounds for harmful microbes. A new bandage developed by researchers at the Swiss Federal Institute of Technology in Luassane (EPFL) could improve the healing process considerably, accelerating the healing process, while stopping bacteria multiplying.Read More

New hydrogel aids skin regeneration to improve wound healing

Healing chronic skin wounds can be difficult, particularly when they span large areas, or when healing is complicated by health problems such as a lack of mobility. A team of researchers from the University of California, Los Angeles (UCLA) has worked to improve the process, creating a more effective method of regeneration through use of a new material that creates a porous scaffold, allowing wounds to heal more effectively.Read More

Expandable sponge-filled syringe that stems bleeding cleared for civilian use

A fast-acting medical device developed for emergency treatment of a gunshot or other penetrating wound on the battlefield has been cleared for civilian use by the US Food and Drug Administration (FDA). The XStat 30 is a plastic syringe that can stop severe bleeding within around 20 seconds through the injection of small sponges into a wound, and will now be available for use by the general population.Read More

New material helps diabetic wounds heal faster

Because they often have weakened immune systems and/or blood flow restrictions, diabetics run a heightened risk of serious infection from even the smallest of open wounds. That's why a team of scientists from Egypt's Alexandria University have developed a means of getting those wounds to heal faster – silver-impregnated dressings.Read More
