This Common Activity Is Reducing Your IQ, According to Research Eric Barker writes Barking Up the Wrong Tree. Lack of sleep affects intelligence Missing an hour of sleep turns a sixth grader’s brain into that of a fourth grader. Via NurtureShock: The performance gap caused by an hour’s difference in sleep was bigger than the gap between a normal fourth-grader and a normal sixth-grader. There is a correlation between grades and average amount of sleep. Teens who received A’s averaged about fifteen more minutes sleep than the B students, who in turn averaged fifteen more minutes than the C’s, and so on. Not only does it affect intelligence, lack of sleep also reduces impulse control. A different mechanism causes children to be inattentive in class. And when we’re tired it’s actually harder to be happy. 5 Horrible Habits You Need to Stop Right Now Chris Pecoraro—Getty Images Negative stimuli get processed by the amygdala; positive or neutral memories gets processed by the hippocampus.

What's that noise I hear when I shut my eyes really tightly? How Well Do You Know Your Shit? Birds do it, bees do it, and even fleas do it. As Taro Gomi once said: everyone poops. Although your poo is leaving your body, those fecal bits can actually tell you quite a lot about the health of your digestive system. So what’s your shit trying to tell you?

Logical Fallacies: The Fallacy Files Body Atlas Reveals Where We Feel Happiness and Shame - D-brief Yellow shows regions of increased sensation while blue areas represent decreased feeling in these composite images. Image courtesy of Lauri Nummenmaa, Enrico Glerean, Riitta Hari, and Jari Hietanen. Chests puffing up with pride — and happiness felt head to toe — are sensations as real as they are universal. And now we can make an atlas of them. Researchers have long known that emotions are connected to a range of physiological changes, from nervous job candidates’ sweaty palms to the racing pulse that results from hearing a strange noise at night. Once More With Feeling More than 700 participants in Finland, Sweden and Taiwan participated in experiments aimed at mapping their bodily sensations in connection with specific emotions. Researchers found statistically discrete areas for each emotion tested, such as happiness, contempt and love, that were consistent regardless of respondents’ nationality. Hot-Headed The findings enhance researchers’ understanding of how we process emotions.
“Ballooning” Spiders Use Electrostatic Forces To Generate Lift — The Physics arXiv Blog Today, we get an answer thanks to the work of Peter Gorham at the University of Hawaii. He says that one idea put forward in the 1830s is that the spiders use electrostatic forces to lift them into the air. However, this idea was rapidly rejected by biologists who claimed that thermal currents could provide all the necessary lift. Now Gorham has re-examined the electrostatic theory and says that it can easily account for all the mysterious flying behaviours of ballooning spiders. First, some background about electrostatics in the atmosphere. He then goes on to calculate the charge that a strand must have to lift a spider of a certain weight. Is it possible for spider silk to become charged in this way? That should allow the silk to become charged as it leaves the spinnerets, a process known as flow electrification. There must be a source for this charge, of course. This idea accounts for all the previously unexplained ballooning phenomena. There is one final mystery, however.
