    The recipes for solar system formation are getting a rewrite

    With a mortar and pestle, Christy Till blends together the makings of a distant planet. In her geology lab at Arizona State University in Tempe, Till carefully measures out powdered minerals, tips them into a metal capsule and bakes them in a high-pressure furnace that can reach close to 35,000 times Earth’s atmospheric pressure and 2,000° Celsius.

    In this interplanetary test kitchen,...

    Venus may be home to a new kind of tectonics

    THE WOODLANDS, Texas — Venus’ crust is broken up into chunks that shuffle, jostle and rotate on a global scale, researchers reported in two talks March 20 at the Lunar and Planetary Science Conference.

    New maps of the rocky planet’s surface, based on images taken in the 1990s by NASA’s Magellan spacecraft, show that Venus’ low-lying plains are surrounded by a complex network of ridges...

    Net to halt runaway airliners

    A gigantic emergency arresting gear system, capable of stopping the largest four-engined jet aircraft without discomfort to passengers, is being developed for the French Ministry of Transportation. The system consists of a nylon net … which engages the aircraft for the full width of its wingspan. Net and airplane are brought to a slow stop by energy...

    The list of diseases linked to air pollution is growing

    To the residents of Donora, Pa., a mill town in a crook of the Monongahela River, the daily haze from nearby zinc and steel plants was the price of keeping their families fed. But on October 27, 1948, the city awoke to an unusually sooty sky, even for Donora. The next day, the high school quarterbacks couldn’t see their teammates well enough to complete a single pass.

    The town was...

    Units of measure are getting a fundamental upgrade

    If scientists had sacred objects, this would be one of them: a single, closely guarded 137-year-old cylinder of metal, housed in a vault outside of Paris. It is a prototype that precisely defines a kilogram of mass everywhere in the universe.

    A kilogram of ground beef at the grocery store has the same mass as this one special hunk of metal, an alloy of platinum and iridium. A 60-kilogram...

    Archival Science

    The July afternoon was oppressively hot in Dayton, Tenn. After a steamy morning session in the county courthouse, the judge had ordered that the trial of teacher John T. Scopes be moved outdoors. As the afternoon wore on, more and more townspeople joined the crowd, which eventually numbered at least several hundred. It was the final day before the case was to go to the jury, and, in a...

    Pioneers in Science Writing

    Starting in the early 1920s, Science Service, which publishes Science News, played a significant role in promoting the public understanding of science. Its staff of writers included several women who were pioneers in the emerging field of science journalism. The Smithsonian Institution Archives has a Web exhibit that highlights the careers of five of these women: Jane Stafford, Marjorie Van...

    Reflections on Art

    Like a defense lawyer in court, David G. Stork was eager to know whether his closing argument was winning over his audience. Would a jury vote to convict? Stork asked the group assembled at NASA Goddard Space Flight Center early this month.
