Scientists report that spontaneous brain activity, bursts of electrical noise in our neurons, may be what causes people to sometimes screw up simple physical tasks. For example, basketball players who miss an easy shot may be able to rightly blame these fluctuations. Researchers at Washington University scanned the brains of volunteers while playing a simple game where they pushed a button in response to an on-screen cue. From New Scientist:
As expected, the brain scans revealed increased activity within the left motor cortex – the region associated with controlling movement of the right hand – shortly after each button-pushing prompt.
Fox and colleagues also monitored spontaneous activity within the left motor cortex by analysing its "mirror image" in the right motor cortex. This allowed them to see how spontaneous brain activity affected each button press, independent of the "task-related" brain signals.
The researchers found that volunteers pressed the button with about half the force, on average, if spontaneous activity occurred a few seconds before each prompt.
Well, it’s finally official. After more than a year in regulatory limbo, The United States Justice Department has approved a $26 billion dollar deal between mobile carriers T-Mobile and Sprint.
Donald Trump says his administration will not provide any waivers or relief for Apple Mac Pro components built in China, and said Apple should instead build its products in the U.S.

Want to keep the dentist away? A little tooth care at morning and night isn’t bad, but it won’t keep the stains from smoking or fried foods at bay for long. If you enjoy your food and want to avoid the consequences, an upgrade from that old analog toothbrush can make a huge difference. Among […]
If your office works at all, it uses Microsoft Office. Those icons for Word, PowerPoint, and Outlook are as familiar around some workplaces as the coffee machine. So familiar, in fact, that they get taken for granted – and rarely used to their full potential. Whether you need a crash course in the essential tools […]
It’s a great time to be a maker. 3D printers are on store shelves for anyone to buy, and coder kits like Arduino and Raspberry Pi are letting kids as young as 9 or 10 dive into the Internet of Things. Here are a few examples of our favorite tech toys, all priced low enough […]
