...happens, the composition of the blood - including hormones, neurotransmitters and metabolic by-products - changes. Throw this much loopy chemistry at a sensitive machine like the brain and it's likely to go on the blink. "There are very real changes that occur in the body very rapidly that might explain the clarity during fasting," says Dr. Catherine Gordon, an endocrinologist at Children's Hospital in Boston. "The brain is in a different state even during a short-term fast." Biologically, that's not good, but the light-headed sense of peace, albeit brief, that comes with it reinforces the fast...
Previous studies have shown that wealthier, educated parents talk to their young children more, using more complex vocabulary and syntax, than parents of lesser means. And these differences may help explain why richer kids start school with richer vocabularies. But what goes on before children can talk, during that phase - familiar to any parent - when communication takes the form of pointing, waving, grabbing and other kinds of baby sign language? Do well-off parents also gesture more to their kids...
That last theory offers the possibility that teachers may be able to use gesture to help school-age kids solidify old ideas and learn new ones. In separate research, Goldin-Meadow found that when children were asked to solve and explain a series of math problems, those who were asked to gesture while they did so were more likely to learn new problem-solving strategies and perform better on future math problems than were kids who did not use gestures. Goldin-Meadow believes that prompting children to gesture gives them the ability to express ideas they had never been able...
Time and again, biologists are finding that Darwin had it right: evolution is the best way to explain the patterns of nature. "You just can't even start to make sense of all this data without a framework of evolution," says Gnter Wagner, an evolutionary biologist at Yale University...
...think in some ways dating outside the humanities fulfils the purpose of the Core Curriculum,” she told me. I started telling my friends to stop pining for awkward poets and start hanging out in the buildings we usually avoid. Which might or might not explain how I ended up at the Miracle of Science Bar & Grill. I was sitting across from a condensed matter theorist. Instead of gloves, he was wearing socks on his hands. I decided to ignore that. Our conversation was going okay. He didn’t compare me to a infinite-dimensional Hilbert...
