• China to cut rare Earths minerals export by 30 percent

    China controls more than 95 percent of the global market for rare Earth elements; China has cut rare earths exports by five to 10 percent a year since 2006; China Daily reported yesterday that the government would again cut rare earths export quotas by up to 30 percent next year, “to protect the metals from over-exploitation”; critics charge China’s real goal is to cripple important industrial segments of Western economies

  • Spray-on skin to be commercialized

    Sheffield, U.K.-based Altrika set to produce a spray version of its Cryoskin donor skin cell product that can be applied in hospitals outside of a sterile surgical environment in order to reduce treatment time; the spray would be stored in individual doses so the right number of skin cells can be selected once the wound is assessed; the cells would then be thawed as the patient is being prepared

  • High performance materials for the tunnel of the century

    On 15 October Swiss engineers finished their work on the Gotthard Tunnel — longest rail tunnel in the world; the 57-km (35.4-mile) high-speed rail link, which will open in 2017, will form the lynchpin of a new rail network between northern and southeastern Europe and help ease congestion and pollution in the Swiss Alps

  • App developed to find crooks

    University of Nebraska researchers are developing an app for iPhone and Droid which will allow police to locate sex offenders, parolees, known gang members, and people with arrest warrants; the Nebraska team is planning to combine police GIS and GPS data into a program that would instantly create maps tailored to officers’ specific locations

  • End to limits on carrying liquids on board in sight

    New bottled liquid scanners unveiled; researchers at the Los Alamos National Laboratory developed a magnetic resonance device to read liquids’ molecular makeup, even when the substances are in metal containers; the device is so sensitive it can tell the difference between red and white wine, and between different types of soda; satisfactory test result may spell the end of limitations on carrying liquids on board

  • NOAA: Global temperature ties for warmest on record

    The first nine months of 2010 tied with the same period in 1998 for the warmest combined land and ocean surface temperature on record (the records go back to 1880); this value is 1.17 F (0.65 C) above the twentieth century average; Los Angeles set a new all-time maximum temperature on 27 September when temperatures soared to 113 F;

  • Geologists warn of warming-induced landslides flattening cities

    There are 39 cities around the world with populations greater than 100,000 — and an untold number of smaller towns and villages — which are situated within 100 kilometers of a volcano that has collapsed in the past and which may, therefore, be capable of collapsing in the future; thinning glaciers on volcanoes could destabilize vast chunks of summit cones, triggering mega-landslides capable of flattening cities such as Seattle and devastating local infrastructure

  • Unease grows about China's rare Earth elements monopoly

    Rare Earth elements are quite abundant in the Earth’s crust, but environmental concerns and aggressive subsidies by China’s government to Chinese manufacturers have led to a Chinese near-monopoly: 90 percent of the world’s rare Earth elements are now being mined and processed in China; growing unease with this Chinese dominance has led to renewed efforts around the world to develop alternatives to rare Earth elements, and find environmentally sound ways to mine them

  • With rising sea levels, the time for adapting is now

    Coastal development has accelerated over the past fifty years; many of the world’s megacities are situated at the coast and new infrastructure worth billions of dollars is being constructed; these developments assume that the stable sea levels of the past several millennia will continue — but this assumption is no longer true

  • DARPA seeks self-aiming, one-shot sniper rifle

    Lockheed Martin awarded $6.9 million to develop a sniper rifle to operate over a range of visibilities, atmospheric turbulence, scintillation, and environmental conditions; the company’s objective is to deliver fifteen field-testable and hardened prototype systems by October 2011

  • Initial tests for buried victims rescue device completed

    New victim detection device has been developed as part of a project aiming to enable people to be found quickly from under collapsed buildings or from natural elements like mud or snow; the detection device could literally be a lifeline for victims of future earthquakes, landslides, or terrorist attacks

  • Ocean-landing asteroid will create huge ozone holes

    To date, 818 asteroids that are at least 1-km wide have been discovered on orbits that could take them close to Earth; if a 1-km wide asteroid were to land in the ocean, it would create a big splash, throwing 42 trillion kilograms of water and vapor — enough to fill sixteen million Olympic-sized swimming pools — across an area more than 1,000 kilometers wide and up to hundreds of kilometers above the Earth’s surface; this will result in the destruction of the ozone layer above the Earth’s atmosphere, exposing humans, animals, and plants to civilization-threatening levels of UV radiation

  • Large parts of the world are drying up

    The soils in large areas of the Southern Hemisphere, including major portions of Australia, Africa, and South America, have been drying up in the past decade as a result of intensified “evapotranspiration” — the movement of water from the land to the atmosphere

  • USAF develops UAVs that fly themselves

    A U.S. Air Force project will allow UAVs to fly themselves — in multiple-aircraft formations — without colliding; the USAF is working to develop systems that unmanned aircraft can use to sense the presence of other aircraft and take action to prevent collisions that are safe enough so that UAVs can perform any Air Force mission

  • ASIS International 56th meeting opens in Dallas, Texas next week

    ASIS International’s 56th Annual Seminar and Exhibits will open in Dallas, Texas, next week; attendees will be able to choose from 160 seminar sessions and keynote speeches and exhibits featuring security technologies and solutions from approximately 700 companies; they will also have the opportunity to meet with more than 20,000 security professionals from ninety countries
