    Scientists have built the first silicon chip equipped with living nerve cells. The "neurochip," a silicon rectangle about 4 centimeters wide immersed in a petri dish, may be the forerunner of bionic eyes or other medical devices engineered from combinations of silicon and living neurons.

    Scientists have invented plastic gels that, like high-tech litmus paper, change color after encountering a target chemical.

    Superfluids are immune to many of the forces that constrain ordinary liquids. Because they have no internal resistance to flow, ultracold helium-4 or helium-3 slips through microscopic holes, flows effortlessly uphill, and flouts efforts to contain for study.

    TOKYO--Circuit designers at NEC Corp. have probed what some thought was a lower limit on the size of microelectronics--and found some give.

    Most diamonds are made with brute force. Extremely high pressures and temperatures inside Earth or in a laboratory, for example, can rearrange the carbon atoms of graphite into the crystalline structure of diamond. Now, researchers have used clever physics instead.

  • 9 Oct 1997

    Scanning tunneling microscopy sketches exquisite atomic-level landscapes of material surfaces, but reveals little information about the identity of those atoms. Now, two researchers have found a way to pluck small groups of atoms from a surface and tell what they are.

  • 21 Aug 1997

    Chemists have constructed a sensor, made from a web of DNA and gold particles, that turns from red to blue when it detects a precise strand of DNA.

  • 5 Aug 1997

    Spin doctors may be the masters of manipulation, but scientists are catching up fast--at least with atoms. In the current issue of Physical Review Letters, scientists describe how to push, pull, and slide individual atoms along a sheet of copper.

    PITTSBURGH--A four-wheel-drive robot named Nomad, one of a new generation of robots designed to explore the moon and Mars, embarked today on a 200-kilometer test drive through a barren desert in the high Andes of Chile.

  • 20 May 1997

    Astronomers' spirits sagged earlier this year when the Hubble Space Telescope's new infrared camera sprang a coolant leak, potentially cutting in half the instrument's planned 4-year lifetime.

  • 2 May 1997

    Energy Secretary Federico Peña said yesterday that he will terminate the department's contract with the operator of Brookhaven National Laboratory, Associated Universities Inc. (AUI).

  • 1 May 1997

    WASHINGTON, D.C.--National Science Foundation director Neal Lane announced here yesterday the 1997 recipients of the National Medal of Science, the nation's highest scientific honor. Also announced were winners of the National Medal of Technology.

  • 22 Apr 1997

    WASHINGTON, D.C.--Scientists have thrown more cold water on a multibillion-dollar fusion project before it even attempts to ignite. A panel of U.S.

  • 15 Apr 1997

    WASHINGTON, D.C.--After 2 years of turmoil, the National Academy of Engineering (NAE) has a new president. William Wulf, a University of Virginia computer engineer, was elected today by the NAE's members to lead their powerful academy into the next century.

  • 10 Apr 1997

    Scientists have invented a computer memory system that uses protons instead of electrons to store data. The new device, described in today's issue of Nature, should be easy to manufacture and could eventually provide a cheap alternative to magnetic hard drives and other storage media.

  • 4 Apr 1997

    WASHINGTON, D.C.--An ambitious program to create superefficient automobiles by the year 2000 will not reach a major milestone, predicts a new report from the National Research Council (NRC).

  • 3 Apr 1997

    SAN FRANCISCO--Scientists have created a new type of ultraviolet laser that might be modified to read compact discs.

  • 28 Mar 1997

    Today is the birthday of Sir Joseph William Bazalgette, an English civil engineer born in 1819 who created a new drainage system for the city of London, greatly improving public health.

  • 25 Mar 1997

    VENICE--Italy's chief research funding agency, the National Research Council (CNR), has a new head: informatics engineer Lucio Bianco, a relatively unknown academic. Bianco is expected to steer the council toward funding more applied research.

  • 21 Mar 1997

    This week, a team of mechanical engineers set a new record for sensitivity: They announced that they can now measure forces as tiny as the weight of a single protein.

  • 18 Mar 1997

    German engineer Rudolf Diesel, the inventor known for his durable engine, was born on this day in 1853. When he was 40, Diesel published ideas for an engine that he believed would be more efficient than either steam or gasoline engines. He was manufacturing his namesake by 1899.
