Exploring the neurobiology of politics, scientists have found that liberals tolerate ambiguity and conflict better than conservatives because of how their brains work. In a simple experiment reported todayin the journal Nature Neuroscience, scientists at New York University and UCLA show that political orientation is related to differences in how the brain processes information. Previous psychological studies have found that conservatives tend to be more structured and persistent in their judgments whereas liberals are more open to new experiences.

Does being bilingual give young children a mental edge, or does it delay their learning? It depends on who you ask. Bilingual education is regarded by some in education policy circles as little more than a half-baked technique of teaching students whose native language is not English. Though it takes many forms, bilingual education programs usually involve teaching students in both their native languages and in English. How much each language is used, and in which academic contexts, varies by program.

At the time of his death of an aortic aneurysm at age 76, Albert Einstein's brain was no bigger, and weighed no more, than the brain of an average older male. But beneath that unique organ's external folds and fissures, our universe was re-conceived. So not surprisingly, when photographs of Einstein's postmortem brain unexpectedly came to light recently, scientists were keen to find evidence of the genius that lay within. The result is a remarkably detailed look at the surface of Einstein's brain, published recently in the journal Brain.

Irritable bowel syndrome has been a tough disorder to understand. Studies have failed to show any structural problems in the gut that would account for the symptoms of pain, bloating, diarrhea and constipation. However, the disorder is real, affecting as many as 15% of Americans. A new study has found a possible connection between IBS and the brain. Researchers at McGill University and UCLA used MRI scans to reveal changes in the brains of women with the disorder. The researchers took MRI scans of 55 IBS patients and 48 healthy women for comparison.

Scientists have discovered the fossilized brain of an animal that lived 520 million years ago. It is the oldest mostly intact nervous system to have ever been found. The incredible ancient brain and nervous system, described in the journal Nature, belongs to an Alacomenaeus , a member of the mega-claw family. These animals earned the name "mega-claw" ( megacheiran ), because they have two large scissor-like appendages that protrude from the top of their heads. Megacheirans lived in the early Cambrian-era ocean, swimming and scuttling around with nearly one dozen little legs, or swimmerettes.

Leave it to science to take all the fun out of something as cosmically pure as love. Theories about love's purpose range from the biologically practical to the biologically complicated. Anthropologists have said it helps ensure reproduction of the species; attachment theorists maintain it's a byproduct of our relationship with our childhood caregivers. And now researchers are exploring what happens physiologically as a romantic relationship progresses. The more we understand it, they say, the better our chances of making love last and of harnessing its potential to improve our emotional and physical well-being.

The latest attack on the Internet and on computers in general is Nicholas Carr's book, "The Shallows: What the Internet Is Doing to Our Brains." Carr and other digital alarmists make a case that seems plausible, at least on the surface. They argue that the advent of the Internet and the proliferation of new communication tools trap us in a shallow culture of constant interruption as we frenetically tweet, text and e-mail. This in turn leaves us little time for deep reading, reflection and serious conversation — pensive activities traditionally thought to build knowledge and wisdom.

Leave it to science to find a way to harsh the mellow of marijuana. A French research team has discovered a natural chemical brake that can tamp down the effects of THC, the main intoxicant in marijuana. They believe it could lead to ways to protect against memory loss, torpor and other side-effects better known as being stoned. “We have this built-in negative feedback mechanism, a brake” on cannabis intoxication, said University of Bordeaux neurobiologist Dr. Pier Vincenzo Piazza, principal author of a study published Thursday in the journal Science.

Eating when you're not hungry--especially high-calorie, high-fat foods--may not always rise to the newly broadened clinical definition of an eating disorder. But the behavior that for many Americans is a routine pastime certainly contributes to excess weight gain, with its implications for health. And it is considered "disordered eating" by most mental health professionals. A study published Thursday in the journal Science adds to evidence that binge eating--and overeating generally--may have a biological basis.
