Researchers have developed a new type of surgical ‘glue’ that can effectively seal internal injuries. Closing up wounds typically calls for sutures or staples, but when it comes to wounds on organs that move a significant amount, such as lungs, this is the first material ever made that can create a complete seal. The glue is made using a combination of proteins similar to those that make up elastin in humans, meaning its not toxic for living human tissue. Best of all, the glue sets in just 60 seconds with the help of a UV light.
