    To Fight Cataracts, It's Fish Yea, Mayo Nay

    Bad news for mayonnaise lovers. A pair of new studies from a Boston research team links this condiment, as well as certain vegetable oils, to an elevated risk of age-related cataracts. One of those studies, however, also suggests that oily fish, the type with dark flesh, hold cataracts at bay.

    Age-related cataracts are the leading cause of blindness. Indeed,...

    Improving Prospects for Functional Foods

    In the past decade, food and dietary-supplement manufacturers have created a new niche industry—one in which their goods do more than provide nutrition or gustatory pleasure. Designed to promote optimal health and reduce risk of disease, such products have come to be known as functional foods or nutraceuticals. Examples include St. John's wort tablets reputed to fight mild depression, calcium...

    Little Big Wire

    In 1986, scientists discovered a new family of materials that can conduct electricity with absolutely no resistance. Because these so-called superconductors work at much higher temperatures than any previously identified superconductors, the discovery was considered one of the most important of that decade. The findings triggered a wave of...

    A Forget-Me-Not Dietary Supplement?

    By the time most people reach their 40s, the mind has lost some of its youthful nimbleness. They learn a little more slowly. They forget more frequently. Sometimes, they don't remember where they put the car keys or the name of that popular actor.

    Although minor memory lapses are no big deal, they might hint at a vulnerability to serious aging-related memory impairments...

    Flawed Therapy: Hormone replacement takes more hits

    Expectations for hormone-replacement therapy for postmenopausal women have turned topsy-turvy in recent years. Initial studies suggesting remarkable benefits from the drugs gave way to reports of little gain. Most recently, the rap sheet on estrogen and progestin includes signs of harm.

    The latest bad news for the treatment appears in two articles in the May 28 Journal of the American...

    Wrong Number: Plastic ingredient spurs chromosomal defects

    The primary chemical in some plastics causes female mice to produce eggs with abnormal numbers of chromosomes, according to a new study. In people, the condition–called aneuploidy–is the leading cause of miscarriages and several forms of mental retardation including Down's syndrome.

    The new finding could shed light on the causes of aneuploidy, but it also raises questions about the...

    Mad Deer Disease?

    This autumn, the nation's big-game hunters are lifting their guns and bows in the service of science. They're collecting the biggest sample ever of deer and elk brains–predicted to total 200,000–to test for a once-obscure wildlife disease that's become the stuff of headlines and headaches coast-to-coast. So-called chronic wasting disease strikes mule deer, white-tailed deer, and elk. It

    The Buck Starts Here

    Poor Susan B. Anthony. A pioneering 19th-century advocate of women's rights, she suffered the misfortune of having her stalwart visage stamped on a wildly unpopular U.S. coin. Because the Susan B. Anthony dollar looks confusingly like a quarter, it never won the public's acceptance.

    Now, 21 years after its introduction, the Susan B. Anthony is about...

    Power plants: Algae churn out hydrogen

    Could the green scum that grows on the walls of a fish tank produce the fuel of the future? Some scientists think so.

    They've found a way to coax green algae into producing significant amounts of hydrogen gas. In these  researchers' view, large pools of algae could generate clean-burning hydrogen fuel for cars and other applications.

    As microscopic plants, algae use...

    Treaty Nears on Gene-Altered Exports

    Last February, negotiators from more than 130 countries met in Cartagena, Colombia, to thrash out rules of conduct for international trade in genetically engineered organisms. Unsuccessful, they returned home.

    Their stalemate persisted through 5 days of resumed negotiations in Montreal last week. Then, at 4:48 a.m. Saturday, the parties agreed to a compromise. This Cartagena...
