"An energy-harvesting circuit based on graphene could be incorporated into a chip to provide clean, limitless, low-voltage power for small devices or sensors," said Paul Thibado, professor of physics and lead researcher in the discovery. The findings, published in the journal Physical Review E, are proof of a theory the physicists developed at the U of A three years ago that freestanding graphene—a single layer of carbon atoms—ripples and buckles in a way that holds promise for energy harvesting. The idea of harvesting energy from graphene is controversial because it refutes physicist Richard Feynman's well-known assertion that the thermal motion of atoms, known…

I have just one word of advice for you: “Plastics,” said the parent’s comfortable friend to Benjamin Braddock. Plastics—the new growth field in 1967, the year The Graduate movie came out—just as computers and then the internet would be to succeeding generations. Plastics—a graduate could make a killing in it. But Ben didn’t want any career advice just then. Just out of college, with no goals at all, the only thing he knew is that he wanted no part of the phony monied world that had been his upbringing. He lolled around aimless at his folks’ upper crust home that year and ended up in an affair with his mom’s socialite friend—her idea, not his. “Mrs. Robinson, are you …

Is Microsoft THAT desperate for money that they can't offer just an ad at the top? I think I might be spotting an opening for competition here. Google is currently only placing 3 on top and 3 on the bottom of search results. Sigh...

As the world becomes more electrified, the race is on to build cheaper, longer-lasting, more energy-dense batteries. One of the most promising technologies in this space is the solid state battery, developed by an absolute legend in the battery world, one of the inventors of the lithium ion battery and recent Nobel Prize winner John B. Goodenough.

On January 9, the World Health Organization notified the public of a flu-like outbreak in China: a cluster of pneumonia cases had been reported in Wuhan, possibly from vendors’ exposure to live animals at the Huanan Seafood Market. The US Centers for Disease Control and Prevention had gotten the word out a few days earlier, on January 6. But a Canadian health monitoring platform had beaten them both to the punch, sending word of the outbreak to its customers on December 31. BlueDot uses an AI-driven algorithm that scours foreign-language news reports, animal and plant disease networks, and official proclamations to give its clients advance warning to avoid …

A molecule made of two rhenium atoms (dark spots) travels around two carbon nanotubes (lighter lattice of spots), settling into the gap between the nanotubes. When the atoms separate by a larger distance, the bond between the atoms is broken, and then later reforms.

A Future with Less Screens Mojo Vision is all about "invisible computing." The company, whose founders include industry veterans from the likes of Apple, Google, Amazon, and Microsoft, wants to reduce our reliance on screens. Instead of pulling out your phone to check why it buzzed in the middle of a conversation, look to the corner of your eye to activate an interface that will tell you in a split second. "We want to create a technology that lets you be you, lets you look like you; doesn't change your appearance; it doesn't make you act weird walking down the street," said Mike Wiemer, cofounder and chief technology officer at Mojo Vision.
