Scientists around the world are constantly cooking up new and better ways to develop nanotechnologies that can be used in everything from detecting breast cancer to building better touchscreens. But there’s a one big problem with working on such a small scale: it’s nearly impossible to monitor how temperatures rise and fall within these structures, because the normal tools are just too big for the job.
With this in mind, researchers in Canada have created the world’s tiniest programmable thermometer – and they made it out of actual DNA. The new device is about 20,000 times smaller than a human hair.
