    Obesity messes with the brain

    Obesity subtly diminishes memory and other features of thinking and reasoning even among seemingly healthy people, an international team of scientists reports. At least some of these impairments appear reversible through weight loss. Researchers also report one likely mechanism for those cognitive deficits: damage to the wiring that links the brain’s information-processing regions.

    A...

    Floral Shocker: Blooms shake roots of flowering-plant family

    Imagine discovering a mammal without mammary glands or an insect with eight legs. Aquatic herbs in the genus Hydatella pose a similar paradox—they lack a defining developmental feature of flowering plants, raising questions about their evolution and rampant speciation during the past 135 million years.

    Evolutionary biologists group together organisms that share unique traits,...

    Tea compound aids dying brain cells

    From Washington, D.C., at the Fourth International Scientific Symposium on Tea and Human Health

    A constituent of green tea can revive moribund brain cells, Israeli researchers report. The team experimented with animal neurons that had been chemically poisoned to model the death of dopamine-producing cells in Parkinson's disease.

    In a test-tube study, low doses of epigallocatechin...

    Universities seek armchair astronomers

    Nonscientists and researchers alike have a chance to see something no one else ever has—a few of the million far-off galaxies that the Sloan Digital Sky Survey has recently photographed. The price of admission: People viewing the new images online must do a little work for the astronomers in charge, classifying individual galaxies as either spiral armed or elliptical collections of stars....

    Slimming on oolong

    Without skimping on portions, rats eating diets including oolong tea gain less weight than those dining teafree, a new study finds. The tea apparently impairs the body's ability to absorb fat.

    The finding supports a weight-control strategy—oolong consumption—advocated by practitioners of traditional Chinese medicine, note Lauren E. Budd and her colleagues at the University of California...

    Old plants were lost in the grass

    An obscure family of small, narrow-leaved water plants that have for years been classified as oddball relatives of grasses turns out to represent one of the most ancient surviving lineages of flowering plants, researchers say.

    These plants, the Hydatellaceae, belong with water lilies near the base of the family tree of flowering plants, say Sean Graham of the University of...

    Social jet lag: Need a smoke?

    From Munich, at the Euroscience Open Forum meeting

    People who have a hard time waking in the morning because their bodies' internal clocks are out of sync with their sleep schedules are said to have "social jet lag." Researchers in Europe have determined that the phenomenon strongly correlates with smoking.

    Battling one's biological clock can leave people weary in the same way as...

    Squirt Alert

    As scientific adviser to a group of Maine watermen, ecologist Larry Harris had heard his share of stories. But one tale, told to him 2 years ago, proved unforgettable. A fisherman related how he had been hauling up a dredge used to scout for scallops in nearby Cobscook Bay when he snagged something novel: a life form resembling blobs of pancake batter.

    In all his...

    Fruits and Veggies Limit Inflammatory Protein (with recipe)

    Over the past few years, many studies have linked an increased risk of debilitating illness—such as heart disease or diabetes—with chronically elevated blood concentrations of a protein typically associated with inflammation. In many cases, people with the indicated illnesses didn't even have a particularly level of inflammation. The good news: A new trial finds that eating plenty of fruits...

    Light Therapy for Tainted Fish

    Aquaculture—farming fish for our dinner tables—is a big and growing international industry. Because many of the tastiest and most-profitable farmed fish are carnivores, their prepared diets usually include flakes or powders made from low-value fish, from fish processed for their oil, or from scraps of fish prepared for restaurants and supermarkets. Fish farmers happily bulk up their products...
