    Age-related anemia hastens death

    From San Diego, at a meeting of the American Society of Hematology

    People whose blood concentrations of hemoglobin decrease as they age are at elevated risk for serious ailments and early death, researchers have found.

    Anemia, an inadequate supply of oxygen-carrying hemoglobin, is rare among young and middle-age people and generally develops from a nutritional deficiency or an...

    Thalidomide-like drug treats blood disorder

    From San Diego, at a meeting of the American Society of Hematology

    A novel drug appears to help people with myelodysplasia, a persistent condition that leaves them short of crucial blood components. The drug could become the first treatment specifically for the condition, says Alan List of the University of South Florida in Tampa.

    In people with myelodysplasia, underproductive...

    Novel drug fights leukemia

    From San Diego, at a meeting of the American Society of Hematology

    An experimental drug helps a small but significant fraction of people with acute myeloid leukemia and causes minimal side effects, research suggests.

    The modest success of the drug tipifarnib is encouraging because the blood cancer is difficult to treat, especially in older patients, says Judith Karp of the Johns...

    Select immune cells help marrow grafts

    From San Diego, at a meeting of the American Society of Hematology

    By excising certain immune cells from donor bone marrow, physicians have devised a new and possibly more versatile way of performing marrow transplants.

    These transplants give healthy, blood-producing cells to people with diseases such as leukemia. In optimal cases, a sibling or someone else with certain immunity...

    Brain gene is tied to obesity

    Researchers studying the DNA of people in Finland and Sweden have amassed evidence that a gene involved in brain chemistry influences whether a person is thin or fat.

    Few specific genes have been convincingly linked to human obesity. A research team headed by Päivi Pajukanta of the University of California, Los Angeles now points the finger at one called solute carrier family 6 member...

    A Tale of Two Landers: NASA's Spirit phones home, but Europe's Beagle 2 remains mum on Mars

    Click on image for a larger viewNASA/JPL/Cornell Univ.

    NASA's latest emissary to Mars, the rover called Spirit, triggered cheers and high fives among mission members when it sent its first signals home soon after touching down on the Red Planet on Jan. 3. In stark contrast, somber but hopeful scientists with the European Space Agency haven't yet heard from...

    Going against the Grain: Aspirin use linked to pancreatic cancer

    In a finding that runs counter to prevailing wisdom, scientists have associated aspirin use with cancer of the pancreas.

    Since past studies linked chronic inflammation to various malignancies, the researchers had expected the anti-inflammatory effects of aspirin to suppress pancreatic cancer. Indeed, a smaller study in 2002 found that people taking aspirin had less pancreatic cancer...

    Flashy Transistors: Electronic workhorses also shed light

    Researchers have discovered that the transistor, long the star of electronics, has a yet-untapped talent–emitting light.

    With that newfound capability, the transistor could also become a stellar device for optical uses, such as computer displays, high-speed telecommunications, and light-based microcircuits, says Milton Feng of the University of Illinois at Urbana-Champaign...

    Neural Road to Repression: Brain may block out undesired memories

    Memory requires collaboration between different brain structures. So does forgetting, a new study suggests.

    Two neural regions join forces to enable people to suppress unwanted memories, say psychologist Michael C. Anderson of the University of Oregon in Eugene and his colleagues. The team has scanned the brains of volunteers who were asked to forget previously viewed words. As...

    Moonlighting: Reflective protein causes squid to shimmer

    As the Hawaiian bobtail squid glides through the ocean on moonlit nights, when darkness alone wouldn't cloak it, reflective materials in its tissues render the animal invisible. Biologists have long known that squid and other cephalopods such as octopuses manipulate light in this way.

    "But nobody could figure out what the agent was that was helping these animals become...
