Apple, Alphabet and Fitbit test FDA fast track for health apps
A few of the tech giants you know are about to get fast-track approval for their digital health efforts. The US Food and Drug Administration has named the companies involved in a recently-instituted "pre-certification" program that determines whether or not they meet baseline quality standards for health software. Apple, Fitbit, Samsung and Alphabet's Verily are among the firms that will help the FDA set the benchmarks and decide just how much information companies need to send if they've been pre-cleared. Depending on how the program fares, companies may get to send less information or even avoid certifying certain apps altogether.
Single atom transistors point to the future of quantum computers, death of Moore's law
Transistors -- the basic building block of the complex electronic devices around you. Literally billions of them make up that Core i7 in your gaming rig and Moore's law says that number will double every 18 months as they get smaller and smaller. Researchers at the University of New South Wales may have found the limit of this basic computational rule however, by creating the world's first single atom transistor. A single phosphorus atom was placed into a silicon lattice and read with a pair of extremely tiny silicon leads that allowed them to observe both its transistor behavior and its quantum state. Presumably this spells the end of the road for Moore's Law, as it would seem all but impossible to shrink transistors any farther. But, it could also points to a future featuring miniaturized solid-state quantum computers.
This electric wire is four atoms thick, and you thought speaker cable was fiddly (video)
This should come as a great relief to anyone planning a quantum computer self-build: wires still conduct electricity and obey key laws of classical physics even when they're built at the nanoscale. Researchers at Purdue and Melbourne universities used chains of phosphorus atoms inside a silicon crystal to create a wire that's just four atoms wide and a single atom high -- 20 times smaller than the previous record-holder and infinitely narrower than anything you'd find at Newegg. The video after the break almost explains how they did it.
