  • Researchers Reverse Effects Of Sleep Deprivation

    "These findings are significant because of their potential applicability," said Samuel A. Deadwyler, Ph.D., professor of physiology and pharmacology at Wake Forest. "This could benefit patients suffering from narcolepsy and other serious sleep disorders. But it also has applicability to shift workers, the military and many other occupations where sleep is often limited, yet cognitive demand remains high." >> Read the Full Article

  • Study links ovarian cancer survival to gene change

    Ashkenazi Jewish women who had changes in the BRCA1 or BRCA2 genes were 28 percent less likely to die from the disease over a follow-up period of up to nine years during the study even though such mutations increase the chances of developing breast or ovarian cancer in the first place, the researchers said.

  • Helium Supplies Endangered, Threatening Science And Technology

    The element that lifts things like balloons, spirits and voice ranges is being depleted so rapidly in the world's largest reserve, outside of Amarillo, Texas, that supplies are expected to be depleted there within the next eight years. This deflates more than the Goodyear blimp and party favors. Its larger impact is on science and technology, according to Lee Sobotka, Ph.D., professor of chemistry and physics in Arts & Sciences at Washington University in St. Louis. >> Read the Full Article

  • Insects' 'giant leap' reconstructed by founder of sociobiology

    Wilson’s article surveys recent evidence that the high level of social organization called “eusociality,” found in some Hymenoptera (and rarely in other species), is a result of natural selection on nascent colonies of species possessing features that predispose them to colonial life. Wilson concludes that these features, principally progressive provisioning of larvae and behavioral flexibility that leads to division of labor, allow some species to evolve colonies that are maintained and defended because of their proximity to food sources. >> Read the Full Article

  • Colon cancer risk traced to common ancestor

    LONDON (Reuters) - A married couple who sailed to America from England around 1630 are the reason why thousands of people in the United States are at higher risk of a hereditary form of colon cancer, researchers said on Wednesday. Using a genetic fingerprint, a U.S. team traced back a so-called founder genetic mutation to the couple found among two large families currently living in Utah and New York. >> Read the Full Article

  • Good News About Ocean Methane

    Santa Barbara, Calif. - Methane, a potent greenhouse gas, is emitted in great quantities as bubbles from seeps on the ocean floor near Santa Barbara. About half of these bubbles dissolve into the ocean, but the fate of this dissolved methane remains uncertain. >> Read the Full Article

  • Silence may lead to phantom noises misinterpreted as tinnitus

    Brazil - Phantom noises, that mimic ringing in the ears associated with tinnitus, can be experienced by people with normal hearing in quiet situations, according to new research published in the January 2008 edition of Otolaryngology – Head and Neck Surgery. >> Read the Full Article

  • New plant study reveals a 'deeply hidden' layer of the transcriptome

    La Jolla, CA – Cells keep a close watch over the transcriptome – the totality of all parts of the genome that are expressed in any given cell at any given time. Researchers at the Salk Institute for Biological Studies and the University of Missouri-Kansas City have now teamed up to peel back another layer of transcriptional regulation and gain new insight into how genomes work. >> Read the Full Article

  • Deep-sea species' loss could lead to oceans' collapse, study suggests

    University of Marche, Italy - The loss of deep-sea species poses a severe threat to the future of the oceans, suggests a new report publishing early online on December 27th and in the January 8th issue of Current Biology, a publication of Cell Press. In a global-scale study, the researchers found some of the first evidence that the health of the deep sea, as measured by the rate of critical ecosystem processes, increases exponentially with the diversity of species living there. >> Read the Full Article

  • Lack of deep sleep may increase risk of type 2 diabetes

    Chicago - Suppression of slow-wave sleep in healthy young adults significantly decreases their ability to regulate blood-sugar levels and increases the risk of type 2 diabetes, report researchers at the University of Chicago Medical Center in the “Early Edition” of the Proceedings of the National Academy of Science. >> Read the Full Article
