• Test strip detects TNT and other explosives in water

    Scientists developed a new explosives detector that can sense small amounts of TNT and other common explosives in liquids instantly with a sensitivity that rivals bomb-sniffing dogs, the current gold standard in protecting the public from terrorist bombs

  • Rapid, low-cost, point-of-care flu detection demonstrated

    The novel H1N1 flu pandemic in 2009 underscored weaknesses in methods widely used to diagnose the flu, from frequent false negatives to long wait times for results; scientists demonstrate a prototype rapid, low-cost, accurate, point-of-care device that promises a better standard of care

  • Some flame retardants make fires more lethal

    Almost 10,000 deaths from fires occur in industrialized countries worldwide each year, including about 3,500 in the United States; scientists find that widely used flame retardants added to carpets, furniture upholstery, plastics, crib mattresses, car, and airline seats and other products to suppress the visible flames in fires are actually increasing the danger of invisible toxic gases that are the No. 1 cause of death in fires

  • A swarm of small satellites to deflect menacing asteroids

    New research suggests that the best way to divert an asteroid hurtling toward Earth is using a swarm of relatively small satellites flying in formation and cooperatively firing solar-powered lasers onto an asteroid; this would be a more effective way than the current methods being contemplated, which are focused on large unwieldy spacecraft

  • Developing crop for livestock in dry climates

    Scientists at the University of Liverpool are working with international partners to develop new forage crop for the hot and dry climate of regions such as Pakistan and Saudi Arabia

  • Machine can tell when a human being is lying

    In a study of forty cases, a computer correctly identifies liars more than 80 percent of the time, a better rate than humans with the naked eye typically achieve in lie-detection exercises

  • New plastics mimic human skin: they “bleed” when scratched, then heal

    Plastics have become so common, replacing steel, aluminum, glass, paper, and other traditional materials because they combine desirable properties such as strength, light weight, and corrosion resistance; a new genre of plastics that mimic the human skin’s ability to heal scratches and cuts offers the promise of endowing military and first response gear – and consumer goods – with self-repairing surfaces

  • 1930s technology to become 21st century tool against CO2 emissions

    Human activity releases 30 billion tons of carbon dioxide into the air each year; a new approach to dealing with the problem has a back-to-the-future glint, leveraging technology that the petroleum industry has used since the 1930s to remove carbon dioxide and other impurities from natural gas

  • Earth's crust is slowly being destroyed

    New research shows that the Earth’s crust is now undergoing high rates of destruction; the research shows the sharp decrease in the growth of the continental crust indicates a dramatic change in the way the Earth has generated and preserved this crust in the last 4.5 billion years

  • 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

  • The Transboundary Agreement is not just about the cost of gas and the environment

    The Transboundary Agreement, which the United States and Mexico reached on 20 February, regulates oil and gas development in the Gulf of Mexico; before the agreement is ratified, there is a need to address serious security issues related to building more oil rigs in the Gulf – for example, the fact that the Mexican government cannot control its powerful criminal organizations, and that it will be easy for terrorists in a small boat to overrun one of these deepwater rigs

  • Firefly technology sheds new light

    A new device, employing the same chemical which lights up fireflies, can easily detect food contamination; the researchers who developed the system hope it will soon be used to test for other diseases, including HIV-AIDS

  • Robot jellyfish for underwater search and rescue

    Researchers have built a robotic swimmer that mimics the motion of a jellyfish; the device will because for underwater search and rescue missions

  • 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

  • Electricity from trees

    Plants have long been known as the lungs of the earth, but a new finding has found they may also play a role in electrifying the atmosphere; scientists found the positive and negative ion concentrations in the air were twice as high in heavily wooded areas than in open grassy areas, such as parks
