    Into the Tank: Pressurized oxygen is best at countering carbon monoxide exposure

    Carbon monoxide poisoning sends roughly 40,000 people to hospitals every year in the United States. Although doctors routinely treat such patients with oxygen, the medical community still hasn't reached a consensus on the optimum dose or best delivery method.

    Scientists report in the Oct. 3 New England Journal of Medicine that breathing pressurized, or hyperbaric, oxygen limits long-...

    Flame Out: Fishy findings sustain, then snuff, stellar career

    Rare in physics, accusations of scientific fraud have sullied the field for the second time in months.

    Investigators have concluded that a young, up-and-coming physicist in fields ranging from molecular electronics to superconductivity repeatedly faked data and committed other types of scientific misconduct.

    The misdeeds of Jan Hendrik Schön, 32, of Lucent Technologies' Bell Labs...

    Hot Spuds: Golden path to acrylamide in food

    The process that imparts a golden hue to french fries and bread crusts also laces such foods with acrylamide, new studies indicate. That chemical causes cancer in laboratory animals.

    Though acrylamide's human toxicity remains unknown, the Food and Drug Administration this week announced plans to study ways to limit its formation in foods.

    The first report of acrylamide in food...

    Molecular Separations: New artificial sieve traps molecules

    Just as a fishing net can catch big fish while letting small ones through, natural, porous minerals called zeolites can ensnare certain molecules while letting others swim free. Now, researchers have created a metal-laced organic solid that they say mimics zeolites and could outperform them for certain industrial and laboratory uses.

    Zeolites can soak up liquid or gas...

    Making Mice Mellow: Rodents yield clues to improved anxiety drugs

    Treatments for anxiety disorders often center on drugs that relieve symptoms but can be addictive and cause drowsiness and other side effects. These medications work on brain-cell receptors for either of two chemical messengers, GABA or serotonin.

    A new study has taken the first steps toward identifying drugs that may pack a more effective anxiety-fighting punch. Mice bred to lack the...

    Solar Surgery: Sunlight acts like laser

    Surgeons may someday use super-concentrated sunlight to burn tumors off major organs. So say Israeli scientists, who have succeeded in channeling sunlight down a fiber optic cable to produce laserlike beams. The device might provide a cheap alternative to medical lasers in countries with limited access to high technology but plenty of sunlight.

    Laser equipment...

    Milestones for Malaria: Parasite, mosquito genes decoded

    About every 30 seconds, another child dies from malaria somewhere in the world. Two organisms, the parasite Plasmodium falciparum and the mosquito Anopheles gambiae, are responsible for most of those deaths. While feeding on human blood, the insect can infect people with the fatal parasite.

    In a dramatic convergence of research described in more than two dozen papers in the...

    Lingering legacy of Sept. 11, 2001, on firefighters' health

    Nearly all of New York City's 11,000 firefighters worked at the World Trade Center towers after the terrorist attack there. Researchers report in the Sept. 12 New England Journal of Medicine that about 10,000 firefighters developed coughs in the days and weeks following the attack, and 332 developed a persistent cough severe enough to require medical leave for at least 4 weeks. Half of the...

    There's life in the old galaxies yet

    According to conventional wisdom, clusters of elderly galaxies settled into retirement long ago. With most of their cold gas already having coalesced into stars, these clusters can no longer make new stars or keep supermassive black holes active.

    But astronomers studying the 100 brightest galaxies in the cluster Abell 2104 have found six active supermassive black holes...

    Carbon nanotubes do some bonding

    Many materials scientists predict that the tiny, hollow cylinders of carbon atoms known as carbon nanotubes will eventually lead to a new generation of supersmall transistors. But first, researchers will need to join nanotubes together.

    A new welding technique may be the answer. Pulickel M. Ajayan of Rensselaer Polytechnic Institute in Troy, N.Y., and his colleagues have managed to join...
