    Dashing Rogues

    In February 1933, the Navy tanker USS Ramapo was steaming its way from the Philippines to San Diego in the midst of an exceptionally strong storm. The 146-meter-long ship was buffeted by near-hurricane–force winds. Early on the morning of Feb. 7, a wave far larger than the others surrounding the ship overtook the Ramapo from behind.

    As the stern of the ship dropped...

    Alaskan coral beds get new protection

    Huge tracts of delicate coral gardens and soft-coral forests off the coast of Alaska will be permanently protected from fishing gear that targets groundfish and shellfish by scraping the seafloor.

    Most of the affected sites have never been disturbed by this gear. The National Oceanic and Atmospheric Administration (NOAA) on June 28 announced its new rule to preserve that...

    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...

    Energy on Ice

    In March 2002, an international team of scientists pumped hot water down a 1,200-meter well located at the edge of the Mackenzie River Delta in northwestern Canada. The water seeped into the pores of the perpetually frozen sediments, melting icelike crystals along its path. These were no ordinary crystals, but frozen cages of water molecules filled with methane, the main constituent of...

    Paint additive hammers coral

    From New Orleans, at a meeting of the Society of Toxicology

    Ocean corals around the world are ill or dead for reasons that remain mysterious. One of the first signs of sickness is bleaching, in which reef-building animals lose the symbiotic algae that give them color and nutrients (SN: 1/30/99, p. 72: http://www.sciencenews.org/pages/sn_arc99/1_30_99/bob1.htm). New laboratory...

    Dying before Their Time

    With one look, you can usually tell whether someone is old or young. Wrinkled skin or smooth. Thinning hair or thick locks. Bifocals or Ray-Bans. These are just a few of the overt clues. Far less obvious are the age-related signs that show up on the molecular level. Ask a geneticist where to look and he may point you to a person's mitochondria. These rod-shaped residents of an animal cell...

    Waste Not: Proteins suggest ways to thwart muscle loss

    Old people, starving people, AIDS patients, cancer patients, and even astronauts. All these groups and others experience muscle atrophy, the wasting away of muscle fiber.

    Two research teams have now revealed details of the biochemical signals that drive muscle atrophy. They include a class of proteins that may trigger this degenerative process.

    The proteins are the "master switch...

    Leaden Gardens

    Soils in many cities of the United States carry a poisonous legacy: heavy concentrations of lead. The metal was deposited for years as fallout from flaking leaded house paint and the emissions of cars burning leaded gasoline. Recognizing the threat posed by tainted soil, environmental scientists have warned that growing edible plants in soils near streets or within several feet of homes and...

    As If You Needed Another Reason to Eat Strawberries (with recipe)

    Whether draped atop shortcake, cooked with rhubarb and slathered over vanilla ice cream, or downed in the garden just after picking, strawberries are one of summer's delights. Now, scientists at Cornell University find that this fragile fruit not only tastes great and contains vitamins but also may offer surprisingly potent benefits in the body's fight against cancer and heart disease.

    Wash Those Hands!

    When physicians talk about food poisoning, they're not usually referring to the effects of natural toxins made by plants or animals. But some foods do carry that danger. For instance, potatoes can develop pest-deterring agents in and just under their skins that can sicken or, rarely, kill a person. And certain fish — such as the infamous puffer — produce chemicals that have done in more than...
