If you want to eat to maximize your mood and brain power, here's what the experts recommend: ? Breakfast: Studies have provided good evidence that a healthy breakfast leads to better cognitive performance, especially in children. ? Enough calories: Few things make people grumpier than being calorie deprived. If you're hungry, anything with calories will help. ? Regular meals: Keeping your blood sugar even by eating regularly ? about every four hours ? will help keep your mood level all day. Conversely, skipping meals and eating erratically will lead to highs and lows.

"Brains on Trial," Thursday and Sept. 19 on PBS, offers a two-part look at "how brains work when they become entangled with the law. " That is not the John Agar 1950s sci-fi flick it might first sound like, but a look at how recent research into neuroscience and brain mapping changes our understanding of basic questions of human reliability, memory and bias among witnesses, juries and judges. These epistemological problems, pondered by philosophers since time immemorial, are no less difficult today; if anything, they are complicated by new knowledge.

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.

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.

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.

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 developed a “proof of concept” drug for stroke patients that helped afflicted mice recover the ability to walk normally. In laboratory experiments, the researchers also found biological evidence that the drug helped grow new neurons in the brain, according to a study published online Tuesday by the journal Stroke. An estimated 795,000 Americans have a stroke each year, according to the National Stroke Assn. in Centennial, Colo. They occur when the brain is suddenly deprived of oxygen and nutrients, either by a blockage in a vessel (which causes an ischemic stroke)

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.

E.L. Doctorow has long operated in the shadow of the Transcendentalists: Emerson, who inspired his 2003 collection of essays, "Reporting the Universe"; Hawthorne, whose story "Wakefield," he updated in 2008. Like them, his great subject is consciousness, what he has called "a mind in the appalled contemplation of itself. " Like them, he is a romantic, a true believer - in the myth of America as a shining city, despite its various and ongoing failures to live up to its better self. His finest efforts embody this tension, between who we are and who we wish we were, between promise and despair.
