    Biohazard: Smoking before or after pregnancy may harm daughters' fertility

    Exposing female mice to chemicals found in cigarette smoke before pregnancy or during the period in which they nurse their young impairs the reproductive capacity of their female offspring, a new study finds.

    Many women stop smoking when they discover they are pregnant, aware that this habit endangers the baby. The new data suggest that may not be enough to protect their daughters' long...

    Fish Killer Caught? Ephemeral Pfiesteria compound surfaces

    A team of researchers claims to have found an elusive algal toxin implicated in massive fish kills along the Mid-Atlantic coast in the 1990s. They say that the compound's characteristics explain why it has been so difficult to track down. Other researchers, however, remain skeptical.

    The hunt for a toxic product of the single-celled alga Pfiesteria piscicida dates to the early...

    Red Heat Might Improve Green Tea

    Most tea drinkers don't give much thought to how tea leaves are processed prior to arriving in a tin or tea bag. However, a Korean team of food scientists has. Realizing that many people are trying to consume more of certain tea-derived antioxidants—especially compounds called catechins—the researchers wondered whether concentrations of those chemicals might be affected by tea-leaf handling....

    Fruity Relief for Weekend Warriors

    After 2 years of planning, you're finally able to afford a long weekend off for that ski trip to Aspen. The first day out, you put in 5 or 6 hours working your way down the slopes. You had planned to do the same thing each of the next 2 days—until you awake feeling sore from head to toe. The next day you feel even worse, so you settle for spending the rest of your trip in the lodge, sipping...

    Easy Answers: Quantum computer gives results without running

    Physicists have long known that quantum computers have the potential to race through calculations trillions of times as fast as ordinary computers do. Now, it seems that those machines may not have to calculate at all to deliver answers.

    That seemingly absurd possibility, which was advanced as a theory several years ago, has now received experimental verification. What's more, although...

    Prions' dirty little secret

    Fifteen years ago, scientists at the National Institutes of Health reported that malformed prions—proteins that can trigger lethal illnesses including mad cow disease—remain on soil surfaces for at least 3 years. Now, scientists report why rain doesn't flush away the prions: The proteins bind almost irreversibly to clay.

    In fact, clay can "retain up to its own mass of ... prion proteins...

    Fruits and Veggies Limit Inflammatory Protein (with recipe)

    Over the past few years, many studies have linked an increased risk of debilitating illness—such as heart disease or diabetes—with chronically elevated blood concentrations of a protein typically associated with inflammation. In many cases, people with the indicated illnesses didn't even have a particularly level of inflammation. The good news: A new trial finds that eating plenty of fruits...

    Novel Approach: Cancer drug might ease scleroderma

    The chemotherapy drug paclitaxel, when given to mice, shows signs of impeding the skin disease scleroderma, researchers report. By slowing skin thickening, paclitaxel might offer a treatment for a disease that has defied cure.

    Scleroderma results when excess collagen protein accumulates in the skin, rendering it fibrous and inflexible. This toughening can cause pain and disfigurement....

    Ultrasound solution to toxin pollution

    Blooms of algae that produce life-threatening toxins regularly plague water supplies around the world. In many cases, the algae's toxins can survive standard treatments for purifying water. Researchers at Florida International University in Miami think they have a sound solution: ultrasound.

    Blasting water with 640-kilohertz ultrasound waves briefly creates high-pressure...
