    Troubling Meaty 'Estrogen'

    Women take note. Researchers find that a chemical that forms in overcooked meat, especially charred portions, is a potent mimic of estrogen, the primary female sex hormone. That's anything but appetizing, since studies have linked a higher lifetime cumulative exposure to estrogen in women with an elevated risk of breast cancer.

    Indeed, the new finding offers a "biologically...

    Bright Lights, Big Cancer

    In late 1987, Richard G. Stevens, then at Pacific Northwest Laboratories in Richland, Wash., typed up a short letter and mailed it to Walter Willett at Harvard Medical School in Boston. The two epidemiologists had met just once, and Stevens wasn't confident that his 209-word note, or the suggestion that it contained about a possible contributor to breast cancer, would inspire any action.

    That's the Way the Spaghetti Crumbles

    Great scientists sometimes do silly experiments. The renowned physicist and Nobel prize winner Richard P. Feynman, for instance, once got it into his head to figure out why uncooked spaghetti doesn't snap neatly in two when you bend it far enough to break. Pay attention next time, and you'll notice that the pasta tends to shatter into three or more fragments of unequal lengths.

    Champion of strength is forged in mighty anvil

    A newly created form of carbon has captured the crown of world's strongest known material. A team of researchers in Germany and France made the new material using a specialized, multijawed anvil that simultaneously squeezed and heated a powder of all-carbon molecules known as buckyballs.

    At 200,000 times atmospheric pressure and a temperature of 2,500 kelvins, the powder...

    Realistic Time Machine? New design could forgo exotic ingredient

    The laws of physics seem to allow time travel, but no one has had much hope of building an actual time machine because it would take such exotic conditions and materials.

    Now, physicist Amos Ori of the Technion Israel Institute of Technology in Haifa has come up with a potentially more practical time machine design. Unlike most previous proposals, this one requires only normal matter...

    Omega-3's May Hit Food Labels

    The Food and Drug Administration has announced that it will allow food manufacturers to make health claims for two omega-3 fatty acids—oils typically found in coldwater fish. Food labels can now note that products containing these oils might provide some protection from heart disease.

    The oils carry unwieldy names and so go by their acronyms: eicosapentaenoic acid (EPA) and...

    Flexible E-Paper: Plastic circuits drive paperlike displays

    In a major step toward electronic paper that works like a computer monitor yet feels and behaves like a page of a book, researchers in the Netherlands have made electronic-ink displays on flexible plastic sheets.

    A U.S. company developed the electronic ink over the past several years. "Just like your newspaper, you can see it in bright light, dim light, or from all angles...

    Cool Cosmos: Orbiting telescope views infrared universe

    Astronomers this week unveiled some really cool images–along with some positively chilling spectra. The new images include pictures of a hidden stellar nursery and the first spectra ever taken of organic material in a remote galaxy. An infrared observatory, the Spitzer Space Telescope, had gathered the data since its launch last August.

    The telescope "will change...

    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...
