Researchers at the Terasaki Institute for Biomedical Innovation and the University of Arizona College of Medicine have developed a topical gel formulation with 4-aminopyridine (4-AP), to treat burn wounds.

Lab-grown brains could help scientists reawaken nerve regeneration.

The device, created by engineers and cancer scientists led by Professor David Flynn, represents an important step toward next-generation implantable photonic medical technologies
