Chocolate Improves Memory…In Snails!

iStock_000003537039_MediumIn the category of “weird news of the day,” it turns out that scientists have discovered a way to study the impact of dark chocolate on memory skills. But not the memory skills of humans, many of whom would crawl on all fours to be chosen to eat chocolate for the advancement of science. No, the participants selected for this particular study were actually snails.

Researcher submerged snails for 30 minutes in either regular water, or water containing epicatechin, a flavonoid found in cocoa. Whenever the snails extended their breathing tubes, researchers poked them with a stick. The lead study author, Ken Lukowiak, Ph.D, compared it to tapping a sleepy student on the nose every time he yawned in class—eventually the student would remember not to yawn. Would the snails do the same?

Hello? Can You Hear Me?

People who own smartphones often end up using their thumbs—a lot!—swiping through various touchscreens on an ongoing basis throughout the day.

All that thumb action can create physical changes in the brain, researchers say, leaving certain regions more active or even enlarged.

Scientists suspected this might be the case, since something similar happens to violinists. Regions of the brain associated with dexterity are larger in musicians who have played the violin for some time. Would smartphone thumbers show similar changes in brain activity?

A number of studies seem to reveal similar findings. In one study, folks were far more likely to cheat on a task in the afternoon than in the morning. In another study, they were more likely to cheat after doing other tasks (like memorizing numbers) that left their brains somewhat fatigued.

The Negative Effects of Electronics

53411926_thumbnailWhile past studies have linked televisions in children’s rooms to a reduction in sleep, until recently few studies examined how kids’ sleeping patterns are impacted by smaller electronics such as smart phones and tablets.

Studies on the impact of small electronics and quality of sleep are emerging now, and the findings are not good.

In fact, in one recent study, researchers found that children who slept near small screens—including those on phones and other portable electronics—reported about 21 minutes less sleep than peers who slept in electronic-free bedrooms. The kids who slept near electronics also reported feeling more sleep deprived.
