The New Yorker has a great piece, “Brain Games,” on Vilayanur Ramchandran, a behavioral neurologist that they dub the “Marco Polo of Neuroscience.” The article explains how his research into the faulty “wiring” associated with disorders such as phantom-limb pain and Capgras delusion has led to low-tech treatments—often mirrors—that “trick the brain” back to normal. It’s an exciting look at science in action.

Dog Consciousness
The Spring 2009 issue of Notre Dame Magazine has a fascinating story on the mental capacity of dogs. In “The Natural Goodness of Dogs,” writer Jake Page relates, among other things, that:
In a recent series of experiments at the University of Vienna, Friederike Range rewarded dogs with a food treat if they held up a paw. Then when a lone dog was asked to hold up its paw, did so, and didn’t get a treat, it would keep on trying as many as 30 times. But when two dogs together were tested, with one of them not receiving a reward, the dog who was unrewarded made a big scene and soon refused to play. “Dogs,” said Range, “show a strong aversion to inequity.”

Better Living Through Chemicals
Harper’s has an interesting article by Mark Schapiro on the efforts of the European Union to quantify the health impact of tens of thousands of chemicals found in clothing, toys, cookware, cosmetics and increasingly, our blood. Naturally, the United States is opposed to it.
In the late 1990s, citizens of several European countries learned from newspaper reports that their infants were constantly being exposed to a host of toxic chemicals. Babies were sleeping in pajamas treated with cancer-causing flame retardants; they were sucking on bottles laced with plastic additives believed to alter hormones; their diapers were glued together with nerve-damaging toxins normally used to kill algae on the hulls of ships. When European health officials tried to look into the matter, they were confounded by how little they actually knew about these and other potentially hazardous chemicals. Regulators discovered that they had no way of assessing the dangers of long-term exposure to everyday products. Some manufacturers of baby goods did not even know what was in their own products, since chemical producers were under no obligation to tell them. Such data, if it existed at all, was secreted away in the vaults of chemical companies and had never been submitted to any government authority.
Fairy Tales and Building Blocks
The latest issue of the New Yorker has two stories that are well worth reading. The first, The Book of Exodus, is an amazing, near-unbelievable article about a Muslim scholar in World War II Sarajevo who risked him life to protect a Jewish treasure. His act set off a cascade of selflessness that could serve as a fable about human kindness and its unexpected rewards. Unfortunately, the article isn’t available online (here’s a link to the abstract), but everyone should try to track it down.
The other story may not be as accessible, but it’s just as fascinating. Michael Specter reveals in Darwin’s Surprise that viruses have repeatedly embedded themselves in our DNA over the course of evolution, changing our genetic code and even enabling some of the developments that determine what it means to be human.
