Called a “regenerative bandage,” the novel material heals diabetic wounds 4X faster than a standard bandage and has the added benefit of promoting healing without side effects.

“Foot ulcers cause many serious problems for diabetic patients,” said Prof. Guillermo Ameer...

Given well-established evidence that free radicals can cause cancer, the research community had simply assumed that antioxidants, which destroy them, provide protection against the disease.

“As opposed to the lung cancer studies, the primary melanoma tumor was not affected,” Professor Bergö says. “But the antioxidant boosted the ability of the tumor cells to metastasize, an even more serious problem because metastasis is the cause of death in the case of melanoma. The primary tumor is not dangerous per se and is usually removed.”
