• DARPA: Break-up of hypersonic airplane/missile no big deal

    DARPA first test of its hypersonic airplane/missile — Falcon HTV-2 — failed after the prototype broke up on re-entering the atmosphere; after investigating the causes of the accident, the agency said it is ready for another test; the HTV-2 unmanned test vehicle had no propulsion of its own, being intended rather to try out new airframe and control technologies for use in hypersonic weapons or aircraft of the future

  • Experts: rare Earths elements headed for 2011 supply crunch

    The prices of rare-Earth elements remained static for decades due to plentiful supplies, lulling the high-tech industry into a false sense of security; this is no longer going to be the case, with a 300 percent spike in prices over the past year alone; with China currently producing 95 percent of the world’s supply. Japan, the United States, and other top consumers, however, are scrambling to find new sources

  • Purdue engineers test effects of fire on steel structures

    Building fires may reach temperatures of 1,000 degrees Celsius, or more than 1,800 degrees Fahrenheit; at that temperature, exposed steel would take about twenty-five minutes to lose about 60 percent of its strength and stiffness; Purdue researchers experiment with ways to make steel more fire-resistant

  • The U.S. rare-Earth industry can rebound -- over time

    Rare-Earth elements are not that rare; the U.S. has plenty of the metals that are critical to many green-energy technologies, but engineering and R&D expertise have moved overseas; responding to China’s near monopoly, companies in the United States and Australia are ramping up production at two rich sites for rare earths, but the process will take years

  • Time to find a second Earth: WWF

    In 2007 Earth’s 6.8 billion humans were living 50 percent beyond the planet’s threshold of sustainability, according to a WWF report; the report says that even with modest UN projections for population growth, consumption, and climate change, by 2030 humanity will need the capacity of two Earths to absorb CO2 waste and keep up with natural resource consumption; if everyone used resources at the same rate per capita as the United States or the United Arab Emirates, four and a half planets would be needed

  • BAE tests defense software based on ALADDIN project

    Coordinating military attacks, managing aerial drones, and monitoring terrorists online could all become easier with new software under trial by BAE Systems; a team of researchers from BAE and the universities of Southampton, Oxford, Bristol and Imperial College London spent five years developing a series of algorithms that allow different computer systems to co-ordinate their actions without a central authority

  • Sucking up oil spills is a cinch

    Cleaning up oil spills is a time consuming, difficult process, but a novel approach uses a new kind of vacuum cleaner that blows bark or other absorbent material onto oil spills, and then sucks the material up again. The vacuum cleaner is four times more efficient in cleaning up after oil accidents than conventional techniques

  • Blood camera detects invisible stains at crime scenes

    At present, blood stains in a crime scene are detected using the chemical luminol; luminol is toxic, however, and can dilute blood samples to a level at which DNA is difficult to recover; it can also smear blood spatter patterns that forensic experts use to help determine how the victim died; luminol can also react with substances like bleach, rust, fizzy drink, and coffee, causing it to produce false positives; University of South Carolina rese3archers offer a better solution

  • U.S. scientists to speak out on climate change

    About half of the new Republican members of Congress are climate change skeptics, and 86 percent of them oppose any climate change legislation that would boost government revenue; many U.S. scientists are joining an effort to speak out on climate change, while other scientists express discomfort with blurring the line between science and policy-making

  • Stealthy robo-snake to gather info in inaccessible areas

    Israeli researchers develop a robotic snake that could be useful in urban and subterranean warfare, enabling the inspection and surveillance of sewage systems, narrow tunnels, or culverts, inaccessible by other systems; the robo-snake can maneuver through difficult terrain, “sneak” stealthily inside buildings, use its sensors to scan their interiors; the robot will be able to carry disposable sensors that could be separated and left behind to monitor activity inside buildings

  • U.S. students trail students from most industrialized nations in math

    The United States ranks 31st out of 56 countries in mathematics skills, falling behind most industrialized nations; most states in the United States rank closer to developing countries than to developed countries in math education; thirteen developed countries have more than twice the percentage of advanced math students as does the United States, including Germany, Canada, the Czech Republic, Japan, Finland, and Austria

  • Best 300 U.S. student hackers compete for cybersecurity scholarships, prizes

    The seventh Annual Cyber Security Awareness Week competition at the Polytechnic Institute of New York University; 120 teams from high schools across the country — consisting of 300 of the U.S. best student hackers — competed under the watchful eyes of representatives from the CIA, NSA, DHS, and NSA; the students compete for scholarships and prizes by solving simulated security crises likely to emerge in an increasingly wired world

  • Raytheon, Cisco support Wounded Warrior Project's IT skills training

    Raytheon provides the WWP’s largest-ever financial grant — $2.5 million over five years; Cisco extends long-standing commitment with technology for new virtual training program; the effort will include the expansion of current, multi-tiered information technology training programs with an added focus on developing new cybersecurity training opportunities

  • Research to help reduce coastal flooding

    According to the Environment Agency’s Flooding in England Report, one in six homes in the United Kingdom are at risk from flooding, and 2.4 million properties are vulnerable to coastal/river floods; coastal areas could be saved from the misery of flooding thanks to new research from the University of Plymouth

  • U.S. military looking for sturdier, more survivable UAVs

    The U.S. military is looking for sturdier, more survivable UAVs; the military regards the airspace over Pakistan and Afghanistan as “permissive environment” — and it wants UAVs to be able to do their work in what it describes as “contested airspace”
