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? 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.

Logical Fallacies Introduction to Argument Structure of a Logical Argument Whether we are consciously aware of it or not, our arguments all follow a certain basic structure. Premise1: If A = B, Premise2: and B = C Logical connection: Then (apply principle of equivalence) Conclusion: A = C In order for an argument to be considered valid the logical form of the argument must work – must be valid. Also it is important to note that an argument may use wrong information, or faulty logic to reach a conclusion that happens to be true. Breaking down an argument into its components is a very useful exercise, for it enables us to examine both our own arguments and those of others and critically analyze them for validity. Examine your Premises As stated above, in order for an argument to be sound all of its premises must be true. There are several types of potential problems with premises. Premises may also be true, as far as they go, but are incomplete. Let’s go back to the transitional fossil example again.

10 Natural Remedies for Swollen Feet and Ankles Swelling in your feet and ankles is called edema, and there are a lot of things that can cause the problem, from high blood pressure to pregnancy. What’s happening is your body is having trouble fighting gravity to move blood and fluids back up your legs, so your ankles, feet, and even your legs can begin to swell. Edema on its own is not harmful, but it is uncomfortable. If you are seeing one foot or leg swelling a lot more than the other, or your face is swelling, you do want to call your doctor, because the cause could be a blood clot, and you don’t want to wait to address that problem. That uncomfortable swelling is not actually a disorder, just a symptom, and the best way to treat it is to treat the root cause. Whatever the reason, these remedies can help give you some relief while you sort out the cause of your edema. 1.
