In addition to the obvious cosmetic uses this could lead to, the finding may have other intriguing applications—including by forensics experts. Something Weird Happened to Astronaut Kelly in Space: NASA will be studying how Scott Kelly's body reacted to almost a year in space, using his twin brother Mark Kelly, who stayed on Earth as a control. One big difference has already been noted: Scott is now 2 inches taller than his twin—but his bragging rights will be temporary.
