• Planetary exploration vehicle for earthly search-and-rescue missions

    A researcher develops a NASA-sponsored autonomous lake lander for the purpose of exploring lakes on distant planets; this mission is many years in the future; in the meantime, the vehicle is ready to deploy on missions related to defense and security, such as harbor surveillance and cleanup operations of littoral munitions dumps and mines; it is also ideal for search-and-rescue operations in oceans, lakes, and hazardous environments, as well as for environmental research projects

  • Army scientists work to improve biothreat detection

    A married couple, both scientists working at the U.S. Army’s Edgewood Chemical Biological Center, one of forty-five Biosafety Level 3 labs in the United States; they collaborate on improving the ability of soldiers and first responders to detect, identify, and protect against potentially lethal biological threat agents

  • New method for cleaning up nuclear waste

    There are more than 436 nuclear power plants operating in thirty countries, and they create a lot of nuclear waste; one of the more toxic elements in that waste is radionuclide technetium (99Tc); approximately 305 metric tons of 99Tc were generated from nuclear reactors and weapons testing from 1943 through 2010

  • Simulation of nuclear fusion shows high-gain energy output

    High-gain nuclear fusion could be achieved in a preheated cylindrical container immersed in strong magnetic fields, according to a series of computer simulations performed at Sandia National Laboratories; the method appears to be fifty times more efficient than using X-rays — a previous favorite at Sandia — to drive implosions of targeted materials to create fusion conditions

  • Solving antibiotic resistance in humans -- and premature bee death

    The stomachs of wild honey bees are full of healthy lactic acid bacteria that can fight bacterial infections in both bees and humans; the finding is a step toward solving the problems of both bee deaths and antibiotic resistance in humans

  • The bioterrorism threat and laboratory security

    Leonard A. Cole, an expert on bioterrorism and on terror medicine who teaches at Rutgers University, investigates the security of U.S. high containment labs in light of the dramatic growth in the number of these labs, which handle dangerous pathogens, following 9/11 and the anthrax attacks

  • National Academies calls for expanded nuclear-fusion research

    A report out on Wednesday from the National Academies says university researchers studying nuclear fusion still have a long way to go before overcoming the many scientific hurdles to the commercial generation of what is hoped to be a virtually limitless supply of energy

  • Balancing safety, risk in the debate over the new H5N1 viruses

    This fall, the U.S. National Science Advisory Board for Biosecurity (NSABB) set off a debate when it asked the authors of two recent H5N1 research studies and the scientific journals that planned to publish them to withhold important details of the research in the interest of biosecurity; the scientific community is divided over the issue of best to balance free research and security

  • Day of human-elements technology nears

    Human-element research looks into biometrics, brain/computer interface and interaction, and human language technology; the U.S. military encourages government agencies, academic institutions, and commercial organizations to collaborate in this research

  • How wings really lift

    See video

    A wing lifts when the air pressure above it is lowered. The explanation typically offered in high school and college physics courses is that this happens because the airflow moving over the top, curved surface has a longer distance to travel and needs to go faster to have the same transit time as the air travelling along the lower, flat surface. This is the wrong explanation, and a 1-minute video released by the University of Cambridge sets the record straight on this much misunderstood concept — how wings lift

  • Lawmakers make steep cuts to DHS research budget

    Over the weekend the Senate approved an omnibus spending bill that would result in deep cuts to DHS’ research and development arm

  • Creating drought-tolerance in crops

    Researchers’ discovery creates new blueprint for engineering drought tolerant crops; the researchers found a way to rewire this cellular machinery to heighten the plants’ stress response — a finding that can be used to engineer crops to give them a better shot at surviving and displaying increased yield under drought conditions

  • DARPA to boost cyber research spending by 50 percent

    Last week, the head of the Department of Defense’s advanced research arm announced that the agency would increase cyber research spending by 50 percent over the next five years to develop both defensive and offensive capabilities

  • Printing a building -- additive manufacturing research moves into construction

    Additive manufacturing — commonly known as 3-D printing — has been used for a surprisingly large range of products and projects, while the devices themselves have continually declined in cost and size; now the technology turns its attention to concrete and building

  • Transforming acids into bases

    Chemists at the University of California, Riverside have accomplished in the lab what until now was considered impossible: transform a family of compounds which are acids into bases; the research offers vast family of new catalysts for use in drug discovery, biotechnology
