A new way to warm up frozen tissue could help with the organ shortage

A new way to warm up frozen tissue using tiny vibrating particles could one day help with the problem of organ shortages.We know how to cool organs to cryogenic temperatures, which is usually below 320 degrees Fahrenheit. But the organs can’t be stored for long — sometimes only four hours for heart and lungs — because they get damaged when you try to warm them up. As a result, more than 60 percent of donor hearts and lungs aren’t transplanted. In a study published today i
