    Fish as Farmers: Reef residents tend an algal crop

    A damselfish cultivates underwater gardens of an algal species that researchers haven't found growing on its own.

    The special alga could be the fishy version of people's domesticated crops, says Hiroki Hata of Kyoto University in Japan. Growth tests of the alga, surveys of its distribution, and genetic analyses support that idea, he and Makoto Kato say in an upcoming Biology...

    Virtual reality for earthquake fears

    From Munich, at the Euroscience Open Forum meeting

    A team of researchers is developing computer-generated, virtual reality technology to prepare 12-to-16-year-old Greek children, including those with special needs, for a terrifying event they're likely to encounter: an earthquake.

    The researchers created a computer model of a local school filled with virtual students. The model...

    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...

    Fruity Relief for Weekend Warriors

    After 2 years of planning, you're finally able to afford a long weekend off for that ski trip to Aspen. The first day out, you put in 5 or 6 hours working your way down the slopes. You had planned to do the same thing each of the next 2 days—until you awake feeling sore from head to toe. The next day you feel even worse, so you settle for spending the rest of your trip in the lodge, sipping...

Propelling this move has been the publication of study after study showing the benefits of whole-grain foods such as oatmeal, brown rice, muesli, and millet. These benefits range from heart health and weight loss to better blood-sugar control.

    Amphibious Ancestors

    Imagine a scale-covered fish that uses fleshy limbs that end in fins to haul itself out of the water. Its mosaic of body features also includes sturdy ribs, the first vertebrate neck, and both gills and lungs. Paleontologists recently unearthed fossils of such a creature, which met their expectations for a proposed missing link between fish and the earliest land vertebrates. These relics...

    Violent Developments

    Henry was headed for serious trouble. The 15-year-old provoked an endless series of fights at school and frequently bullied girls. Teachers regularly suspended him for his classroom disruptions. Older students taunted Henry in the hallways by calling him a sexual pervert or jeered him for having been held back in kindergarten. At home, his father browbeat and denigrated the boy, while his...

    Meat Poses Exaggerated Cancer Risk for Some People

    Last year, the federal government's National Toxicology Program confirmed what many researchers had long been reporting: The heterocyclic amines that form in overcooked meat can trigger colon cancer in animals and probably do the same in people. Now, researchers studying mice have identified a gene that is needed to keep individual animals from becoming especially vulnerable to these...

    Easy Answers: Quantum computer gives results without running

    Physicists have long known that quantum computers have the potential to race through calculations trillions of times as fast as ordinary computers do. Now, it seems that those machines may not have to calculate at all to deliver answers.

    That seemingly absurd possibility, which was advanced as a theory several years ago, has now received experimental verification. What's more, although...

    Finding dirty diesels

    Diesel-fueled vehicles have gained notoriety for their oily carbon emissions. However, there's wide variability in how much of this soot any car emits. A new Dutch study finds that just 5 percent of cars—mostly diesel-fueled vehicles—account for 43 percent of tailpipe-soot releases.

    Andy Kurniawan and Andreas Schmidt-Ott of Delft University of Technology analyzed soot emissions from...
