We'll go ahead and warn you: if you're hoping to purge your mind of all things science this weekend, this post isn't the one to be reading. For the rest of you knowledge seekers, Arizona State University researcher Wayne Frasch has developed a biosensing nanodevice that could possibly revolutionize health screenings and speed up that grueling airport security process. Put simply (well, as simply as possible), he discovered that the enzyme F1– ATPase can be equipped with an optical probe and "manipulated to emit a signal when it detects a single molecule of target DNA." Currently, a prototype of the DNA detector is already being worked up, but there's no word on when (or if) the device will escape the lab and hit the commercial realm. Still not geeked out? Hit the read link and hold on for dear life.
