In the future, your heart could be repaired with gold nanowire cell patches. Researchers at MIT and Harvard University have developed tiny gold-studded scaffolds that can be used to build tissue in which cells have a synchronous beat, a possible repair tool for treating heart-attack victims.In a studyreported in Nature Nanotechnology, Daniel Kohane, a professor in the Harvard-MIT Division of Health Sciences and Technology (HST), and colleagues improved the electrical conductivity of scaffolds used to grow cardiac cells.They devised a new scaffold material but based it on alginate, an orga...

Scientists have come up with a material, essentially an ink, that they say could be used to safely test liquids brought on board airplanes. New nanomaterial from XploSafe could theoretically allow the public to bring more liquids on board airplanes again.XploSafe If a group of scientists can get their project off the ground, there's achance U.S. air travelers may one day be able to bring aboard more liquids in their carry-on luggage again.The team, led by Oklahoma State University chemistry professor Allen Apblett, has come up with what i...
