The outward perception of VR to the less initiated is that the headsets foster a very isolated or anti-social experience.

Unbeknownst to those same people, virtual reality headsets are opening up worlds of potential when it comes to engaging with our fellow humans.

Facebook IQ is the social network’s window into the people that power social media; one that marketers can peek into to get a better idea of what makes people tick. A recent entry on the People Insight portion of the website tackles VR and how it facilitates a social connection.

Elon musk: moving toward universal basic income due to automation | CNBC

2017 is already shaping up to be a big year for the concept of Universal Basic Income (UBI). The idea to build an unconditional income floor to cover the basic needs of each citizen has been gaining worldwide attention and traction. In just the first 10 days of 2017, Finland has already launched a trial, a nonprofit in India is preparing to launch their own, Scotland is seriously considering trials, and several South Korean presidential candidates are now calling for support for UBI.

But before we turn our focus to the latest happenings, I want to look back and highlight some of the best videos of 2016 that explained and advocated for Universal Basic Income.

In Brief

  • By mimicking the way neurons fire in the hippocampus during natural memory creation, a brain implant was used to successfully plant memories in the brains of rats.
  • Though human implementation is far off, this breakthrough in cracking the hippocampus’ mathematical “memory code” has very important implications for health and research.

Memories are the faintest, most ethereal wisps of our neurophysiology — somehow, the firing of delicate synapses and the activation of neurons combine to produce the things we remember. The sum of our memories make us who we are; they are us, in every way, and without them we cease to be.

So it’s needless to say that there’s a pretty significant premium on discovering new ways to combat memory loss. Most of these involve physiological and biological methods, but some scientists, such as Theodore Berger of the University of Southern California, are beginning to turn toward technology. If any of these methods are successful, it would mean the possibility of perfect lifelong memory recall.

Synthetic chemicals commonly found in insecticides and garden products bind to the receptors that govern our biological clocks, University at Buffalo researchers have found. The research suggests that exposure to these insecticides adversely affects melatonin receptor signaling, creating a higher risk for metabolic diseases such as diabetes.

Published online on Dec. 27 in Chemical Research in Toxicology, the research combined a big data approach, using computer modeling on millions of chemicals, with standard wet-laboratory experiments. It was funded by a grant from the National Institute of Environmental Health Sciences, part of the National Institutes of Health.

Disruptions in human circadian rhythms are known to put people at higher risk for diabetes and other metabolic diseases but the mechanism involved is not well-understood.

A strange beeping noise in the Arctic has Canadians puzzled. Is it marine mammals doing something weird? A foreign submarine? Collective hallucination?

A military patrol and acoustic specialists are being dispatched to investigate, the army said Thursday.

Speculation has abounded since Inuit hunters in the village of Igloolik heard the beep several times off the Fury and Hecla Straight late last year.

Scientists simulate evolution in the lab by introducing mutations iteratively into biomolecules such as nucleic acids and selecting for desired properties. When carrying this process out specifically on RNA molecules, they can evolve the RNAs to bind specific small molecules. But many of these so-called aptamers don’t bind well to their targets when put inside cells because they don’t fold into stable structures.

“As we solved the structures of naturally occurring aptamers, we noticed they had much more complex secondary and tertiary structures” than versions made in the lab, says Robert T. Batey of the University of Colorado, Boulder. “So we decided to use these naturally occurring RNA folds as starting points” for producing more stable artificial aptamers.

To prove their concept, Batey and coworkers used RNA sequences from naturally occurring ribozymes and riboswitches as scaffolds to evolve aptamers that bind amino acids and other small molecules used to make neurotransmitters (Nat. Chem. Biol. 2017, DOI: 10.1038/nchembio.2278). The resulting aptamers are selective for these precursor molecules over structurally similar amino acids and the neurotransmitters themselves.
