For years, I've thought that low-level background noise can actually help concentration. Bart Kosko talks about this notion in his book Noise
. There's also recent research
suggesting that noise can improve cognitive performance in children with ADHD. However, physiologist Mark Andrews of the Lake Erie College of Osteopathic Medicine writes in the new issue of Scientific American Mind that noise can lead to stress which actually impairs learning and memory. Bottom line? When it comes to noise, YMMV. From SciAm:
Several studies have indicated that stress resulting from ongoing white noise can induce the release of cortisol, a hormone that helps to restore homeostasis in the body after a bad experience. Excess cortisol impairs function in the prefrontal cortex–an emotional learning center that helps to regulate “executive” functions such as planning, reasoning and impulse control. Some recent evidence indicates that the prefrontal cortex also stores short-term memories. Changes to this region, therefore, may disrupt a person’s capacity to think clearly and to retain information.

That point of light between Saturn’s rings is Earth, captured by NASA’s Cassini spacecraft on April 12. More about the image here at NASA JPL. It reminds me of the last photo taken by the Voyager I spacecraft before engineers shut off its imaging systems. Carl Sagan had persuaded NASA to turn Voyager I’s cameras […]
As AI improves, the mystery of consciousness interests more programmers and physicists.
Most of us need a computer interface implanted in our brains like we need a hole in our head. That said, there are benefits to bridging the gap between mind and machine. Joel Murphy is the founder of OpenBCI, an inexpensive, and non-invasive, brain-computer interface (BCI) platform. People have used OpenBCI to control robots, compose […]

Thinking of a business idea is the easy part. Doesn’t even have to be a “good” idea, you can still get people to throw money at a non-existent venture, but to do that you need to at least have something even resembling a viable business plan. Why doesn’t anyone do it then? Because building that semi-viable […]
The Twisty Glass Blunt is an intriguing product that claims to abolish the need to ever buy or use rolling papers. And, well, it does if you so choose. You can cut down on the waste this 4/20, and everyday after when you’re smoking with this clever piece.Built with a German-engineered glass tube and inner […]
