    For some scientists, a new bank may prove more popular than their local credit union.

    Scientists have identified the gene responsible for a rare form of endocrine tumor.

    Some smokers may be more susceptible to DNA damage from tobacco smoke and thus more likely to develop lung cancer.

  • 16 Apr 1997

    Citing examples of data-hoarding by colleagues, some scientists have griped that commercialism and competition are destroying the once-congenial atmosphere of U.S. academic labs.

    Fish living in waters near the North and South Poles separately evolved nearly identical antifreeze proteins to keep their blood and organs from freezing.

  • 11 Apr 1997

    In one of the greatest moments in modern medical science, American microbiologist Jonas Salk on 12 April 1955 pronounced his newly invented polio vaccine safe and effective in almost 90% of cases.

    Scientists have failed to find any trace of DNA in insects trapped in amber some 30 million years ago.

    Peer pressure from high school potheads isn't the only reason people start smoking marijuana: A new study suggests that some people inherit an ability to enjoy a marijuana high.

  • 4 Apr 1997

    Scientists have devised a computer model that may help solve a long-standing mystery: how physiological factors such as metabolic rate and life-span are related to body size.

  • 2 Apr 1997

    Today is the 70th birthday of Elizabeth Hay, an embryologist at Harvard Medical School who, through pioneering studies on regeneration of amphibian limbs, has shed light on the cellular mechanisms that transform normal cells into tumors.

  • 1 Apr 1997

    The mammals' main claim to fame--besides hair and nipples--is its bulging forebrain, or cerebral cortex, which controls aspects of thought and emotion.

  • 31 Mar 1997

    Scientists have devised a clever form of bug-to-bug combat to fight Chagas' disease, a potentially fatal muscle infection transmitted by the aphidlike kissing bug. The new weapon is a bacterium, normally found in the bug's gut, that is engineered to produce a lethal protein.

    When a Russian passenger jet crashed in Norway last fall, forensic scientists had the gruesome task of identifying victims from sometimes minuscule body parts.

    Have you ever wondered how your palm became different from the back of your hand? Scientists now think they have a clue to the answer: They have found the genes in chickens that tell cells whether they lie on the front or on the back of a developing limb.

  • 27 Mar 1997

    Scientists have discovered a gene, the inactivation of which may help take the brakes off the development of several major cancers, including those of the brain and prostate.

  • 26 Mar 1997

    Today is the 86th birthday of Sir Bernard Katz, a German-born English physiologist who elucidated how nerve cells transmit signals.

  • 26 Mar 1997

    Scientists have the first solid evidence that atrial fibrillation, an irregular heartbeat that affects as many as 2 million Americans and is a major cause of strokes, is inherited in some families.

  • 25 Mar 1997

    Genes vary from person to person in a lot of little ways, much as two cars of the same model can come with different options. But in genes, differences as small as a point mutation--the alteration of a single base pair--can lead to disease.

    Asexual reproduction is usually considered a way of life--an evolutionary choice a species makes when the drawbacks of sex outweigh its long-term benefits.

    For many viruses, infiltrating a cell and replicating is only half the battle. Copies of the virus must then escape to infect other cells. Some viruses explode out of a host cell, destroying it; others, like the influenza virus, take a gentler path.

  • 21 Mar 1997

    Molecular sleuthing by military pathologists has exhumed the first fragments of the genetic blueprint of the virus behind the flu pandemic of 1918, which killed 20 million to 40 million people worldwide.

  • 20 Mar 1997

    WASHINGTON, D.C.--After Christine DeMark told her boss she was getting a test for a gene defect linked to Huntington's disease, her employer "did everything they could to force me to quit," she said at a press conference here today.

    For the second time in 2 months, scientists have reported the discovery of a gene linked to childhood glaucoma. This time, it's a gene for primary congenital glaucoma, a condition that strikes about 2000 infants and young children in the United States each year.

    Gout and multiple sclerosis (MS) may seem worlds apart, but researchers may have found a beneficial connection between the two disorders.
