    Back from the Dead?

    In December 1938, Marjorie Courtney-Latimer, curator of a natural history museum in East London, South Africa, went to the docks to look for interesting specimens among the day's catch. What she found one day she later described as "the most beautiful fish I had ever seen ... a pale mauve blue with iridescent silver markings." The discovery sent scientists into a frenzy.

    Juice May Slow Prostate Cancer Growth (with recipe)

    Prostate cancer will claim the lives of an estimated 30,000 men in the United States this year. The second leading cause of cancer death in men, its incidence climbs with age. In Western countries, the disease is reaching nearly epidemic proportions among the elderly. However, the cancer can grow so slowly that many men with prostate cancer will die of something else first.

    Urban fish show perturbed spawning cycle

    From Baltimore, at a meeting of the Society of Environmental Toxicology and Chemistry

    Sediment-dwelling English sole living in and around Seattle's urban waterfront exhibit spawning anomalies that might compromise their reproductive success, a team of aquatic biologists finds. The changes indicate chronic exposure to environmental contaminants that mimic the animals' own estrogen, the...

    Light Pedaling: Photonic brakes are vital for circuits

    Just as optical fibers have replaced most electrical wires for long-distance telecommunications, light-based circuits may replace electrical ones in applications involving vast flows of data within computers and networks. Now, a team of industrial researchers has taken what may be a crucial step toward such photonic circuitry: They've found a way to dial down the speed of light within...

    Armor-Plated Puzzle

    A few years after Francis H. Crick and James D. Watson unveiled the structure of DNA in 1953, they rocked the fledgling field of molecular biology again with a bold notion: Viruses are, in part, structured as crystals are. That idea captivated Donald L.D. Caspar and Aaron Klug, who then systematically applied what they knew about crystal geometry to classify and predict the structures that...

    Tobacco treaty on its way

    On Nov. 30, 2004, Peru became the 40th country to ratify the World Health Organization (WHO) Framework Convention on Tobacco Control (SN: 7/5/03, p. 14: Available to subscribers at Tobacco treaty penned). As a result, the accord will soon become international law. Officials of WHO, a United Nations agency, say the convention is one of the most rapidly embraced U.N. treaties of all time.

    Smoking out a source of painful menses

    Roughly half of menstruating women regularly experience cramps. The pain, which can be debilitating, accounts for some 600 million hours of lost work time annually in the United States alone. A study now finds that exposure to secondhand smoke may trigger this common gynecologic disorder.

    Changzhong Chen of the Harvard School of Public Health in Boston and his colleagues studied 165...

    Hot Crystal

    There's a gleam in electrical engineer Shawn Yu Lin's eyes these days. It's a reflection of yellowish light given off by a brightly glowing metallic flake inside a vacuum chamber. Heated to incandescence by an electric current, the metal sliver in Lin's lab at Sandia National Laboratories in Albuquerque is made of tungsten, as is an ordinary light-bulb filament. But this experimental filament...

    Tobacco treaty penned

    Every day, people around the world light up some 15 billion cigarettes. This addiction to tobacco has reached epidemic proportions, according to the World Health Organization in Geneva. In hopes of curbing the escalating health and economic toll associated with tobacco use, negotiators from around the world drafted a tobacco treaty in May at the 56th World Health Assembly. On June 16, the...

    Second cancer type linked to shift work

    Two years ago, a pair of research teams each reported finding an elevated risk of breast cancer among women who sometimes worked nightshifts. One of the teams now finds that those women also face an increased risk of colorectal cancer.

    Eva S. Schernhammer of Brigham and Women's Hospital in Boston and her colleagues pored over data on 600 colorectal cancers diagnosed among 78,500 nurses...
