This week on Quirks and Quarks, the national science radio program on the Canadian Broadcasting Corporation, there a fantastic
segment on the neurology of gambling -- sticking the heads of gamblers in fMRIs and having them play games of chance illuminates an awful lot about why our brains make us gamble. It turns out that the reward system that lights up when we get a near-miss in a game of skill (which makes sense) gives us the same reward when we have a near-miss in a game of chance (but only if we get to make a choice in the game, such as picking our lotto numbers, even though this has no influence over the outcome of the game).
One of the mysteries of gambling is that even when we should know we're going to lose, we somehow think we're going to win. Dr. Luke Clark, from the Department of Experimental Psychology at the University of Cambridge, may have discovered one of the reasons why. Using MRI, he studied brain activity in people gambling, looking particularly at "near misses" in which a loss seems close to a win. He found that the brain activated the same reward system that is activated in a real win, despite the fact that people report that these near misses are unpleasant.
Losers With Winners' Brains
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Dr Gale Ridge is a public entomologist at the Connecticut Agricultural Experiment Station, where an average of 23 people a day call, write or visit; an increasing proportion of them aren’t inquiring about actual insects, they’re suffering from delusional parasitosis, and they’re desperate and even suicidal.
Biologist Nipam Patel and his team at UC Berkeley study how butterflies develop wing shape and color by performing surgery on caterpillars, creating translucent windows in their cocoons.
You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
