Embryo-inspired bandages close wounds better than Band-Aids
Common wound dressings usually just protect your cuts from the elements and from infection. A dressing developed by a team of researchers from Harvard's Wyss Institute, Harvard's John A. Paulson School for Engineering and Applied Sciences and McGill University, however, can actively help and speed up the healing process. They're calling the hydrogel-based material active adhesive dressings or AADs, and they were apparently inspired by the skin of developing embryos that can heal itself completely without forming scar tissues.
