Imagine yourself in a room surrounded by eleven objects arranged in a circle. You memorize the position of the objects, then you close your eyes, and rotate a third of the way around (120°). Keeping your eyes closed, can you point to the object that was behind you before? Most people can do this without much difficulty, and only take an instant longer than if they'd stayed in the same position.
Now imagine the objects are rotating on a turntable as you yourself rotate, so that the same........ Read more »

A recent systematic review and meta-analysis shows that at worse antidepressants are not effective for juvenile depression and at best better research might proof this conclusion wrong.Juvenile meaning depression among children and adolescents.The figure above is the forest plot of this systematic review:Forest plot of rate ratios (RR, with 95% CI) of responses to drug or placebo in 30 randomised double-blind placebo-controlled comparisons of rates of ‘response’ to antidepressants v.........

Answering seems simple enough. For many people however, the need to avoid criticism and seek praise causes them to respond in a manner consistent with expected norms. Self-reports of dietary intake can be biased by these tendencies, tainting consumption data collected by the health community. Everyone knows they should eat five or more servings of [...]ShareThis... Read more »

Like many bachelors, I regularly eat meals heated up in a microwave oven. I'd like to think I eat a somewhat lower percentage of frozen dinners than others in my situation, but even when it comes to food I cooked myself I usually don't have the time or patience to cook a recipe for one every night. That means I'm often eating reheated leftovers from the trusty Radar Range. The microwave oven works using dielectric heating, a process in which the movements of dipolar bonds are coup........

In an earlier post on the Durable effects of concentrated disadvantage on verbal ability among African-American children I reported some rather depressing, if excellent, research measuring the cognitive penalties children suffer along with, and likely as consequences of, serious disadvantage. There's some relevant good news in this short paper by Gormley, Phillips and Gayer. (Also available at the publications section of the site of the Crocus project.)This time around the data reports that........ Read more »

The type skull of Velociraptor mongoliensis. From Osborn, et al. 1924.
By the summer of 1993 Velociraptor had become a household name. Although Deinonychus had long been my fleet-footed favorite the olive-green "clever girls" of Speilberg's film soon outshone all of their relatives and gave Tyrannosaurus a run for it's money.* Velocriaptor is hardly a new dinosaur, however. It was discovered during the famous expeditions to Mongolia made by the AMNH in the 1920's, t........ Read more »

Contamination of groundwater by the poisonous element arsenic is a major health risk for millions of people, particularly in Southeast Asia.
Up until now, identifying high risk areas has required expensive surveys based on sampling and analyzing groundwater directly from suspect areas.

When we talk about anti-viral T cells, we’re usually talking about cytotoxic T lymphocytes (CTL) that recognize a peptide in association with class I major histocompatibility complexes (MHC class I). MHC class I is extremely polymorphic; there are many hundreds of different MHC class I alleles.
At any rate, that’s true for the classical ... Read more »

The youth of today - they seem so fearless, so pleased with themselves, don't they? If that's the perception, there are at least two possible explanations. Perhaps today's youngsters really are more egotistical. Alternatively, maybe levels of youthful narcissism haven't changed, it's just that, for any given era, the older folk will always think young people are full of themselves.In what they describe as "the most comprehensive examination to date" of this iss........
