    Nerve cells threatened by stroke or degenerative diseases may have a surprising new ally--microscopic spheres of carbon called buckyballs.

    Sitting in the woods waiting for an owl to poop might seem like an unrewarding research assignment.

  • 14 Aug 1997

    The biological clock of the worm known as Caenorhabditis elegans ticks fast, but these clever nematodes have a way to put aging on hold. In times of stress, such as food scarcity, they can store up fat and enter a state of suspended animation for 2 months or longer.

    This month marks the 100th anniversary of the discovery by Sir Ronald Ross that mosquitoes transmit malaria. The popular view had been that malaria was caused by bad air (mal aria) or contaminated water.

    ROCHESTER, NEW YORK--The fungus Fusarium graminearum can devastate a wheat crop, killing plants and contaminating the survivors with a toxin that sickens humans and animals.

  • 7 Aug 1997

    Researchers have discovered a landmark clue to what causes the nerve cell loss in a group of seven deadly neurological conditions, the most common of which are Huntington's disease and Machado-Joseph disease (MJD).

    Today is the birthday of Alexander Fleming, a Scottish bacteriologist born in 1881 who accidentally discovered the antibiotic penicillin, one of the most important medicines of the 20th century.

  • 6 Aug 1997

    Researchers around the world are about to get their first detailed look at the genetic blueprint of a pathogenic microbe that causes most peptic ulcers.

  • 5 Aug 1997

    The rise of bacteria resistant to antibiotics has left researchers scrambling to develop more powerful drugs.

  • 4 Aug 1997

    Yesterday was the 79th birthday of Frederick Sanger, an English biochemist who was the first to take apart a protein molecule, chemically removing one amino acid at a time.

    Women who have had breast cancer are often told they should think twice about having a child because pregnancy could worsen their disease.

    Live high, train low--that's the guide to faster footwork, according to a paper published this month in the Journal of Applied Physiology. The study found that runners can shave crucial seconds off their time if they live at high altitudes but train closer to sea level.

    Vegetables with genetically engineered pest resistance are already appearing on supermarket shelves, but scientists have had a much harder time controlling the sizes and crop yields of many vegetables.

  • 28 Jul 1997

    Today is the 72nd birthday of Baruch Blumberg, an American research physician whose work has led to blood screening and a vaccine against hepatitis B.

  • 28 Jul 1997

    Scientists have known for decades that the human body requires iron to function properly. But exactly how this crucial nutrient gets from food into the body has been a long-standing mystery.

  • 25 Jul 1997

    BOZEMAN, MONTANA--Antibodies in mother's milk help protect newborn mammals against many infectious diseases in the critical first few weeks of life.

  • 23 Jul 1997

    There's a new way to watch proteins shimmy and dance as they carry out their biological tasks. Researchers traditionally follow these shape changes spectroscopically, deducing them from changes in the molecules' ability to absorb particular wavelengths of light.

  • 18 Jul 1997

    In search of tiny amounts of antibodies, medical physicist Rosalyn Yalow developed a technique that came up very big for biomedical researchers.

  • 18 Jul 1997

    The first genome sequence of a commercially and scientifically valuable group of bacteria has been completed by an international team led by researchers in the European Union (EU).

  • 17 Jul 1997

    Several fatal neurological diseases--including Creutzfeldt-Jakob disease (CJD) in humans and scrapie in sheep--are marked by the accumulation of protein deposits in the brain.

  • 15 Jul 1997

    Killing off a pneumonia-causing bacterium in infected cardiac patients reduced the risk of a second heart attack, cardiologists have found.

  • 15 Jul 1997

    A child born to a mother with a high fever during labor and delivery could be up to nine times as likely to develop cerebral palsy (CP) as one born to a healthy mother.

  • 14 Jul 1997

    On this day in 1970, molecular biologist Hamilton Smith broke new ground for biotechnology. In two papers published in the Journal of Molecular Biology, he described a new class of enzymes--restriction enzymes--that scientists now use to precisely snip DNA.
