While implanted artificial teeth do offer a longer-term alternative to dentures, they may need to be surgically replaced if gum infections occur. Scientists are thus working on a better implant, that would generate electricity via mouth movements.

Diabetic skin ulcers often take a long time to heal, sometimes even leading to complications that result in amputation. A new hydrogel is designed to help keep that from happening, by delivering oxygen directly to such wounds.

When someone is suffering from a skin disease, diagnostic devices are often used to determine what disease it is, and how it's progressing. A new adhesive patch could make doing so quicker and easier than ever – and it's inspired by a diving beetle.

Bandaged wounds need to be checked for infection, yet removing the bandage to check the wound can delay its healing. Australian scientists may have a fix for this paradox, in the form of a dressing that glows if the wound is infected.
