• Russian scientists plan to save Earth from asteroid

    The asteroid Apophis measures approximately 350 meters (1,150 feet) in diameter; if it were to hit Earth when it passes nearby on 13 April 2036, it would create a new desert the size of France; Russian scientists plan to do something about it

  • Israel's military avatar: Robots on the battlefield, II

    With self-detonating grenades, thinking bullets and robot warriors, humans on the frontline could soon be a thing of the past; Israel’s military industries develop robotic systems to aid soldiers in the field, but also to ward off threats from afar

  • A 79-year-old unlicensed blimp enthusiast runs afoul of FAA

    A 79-year old unlicensed pilot-inventor from Oklahoma built a blimp in his backyard; the last trial flight ended with the blimp coming down on an interstate motorway, causing traffic disruption; the FAA found that the blimp-happy septuagenarian does not have a flying license, medical certificate, or air-worthiness documents for his craft; undaunted, Marvin Polzein says: “”I know myself. I’ll get back on it again. I’ll make the corrections, and we’ll try it again”

  • Israel's military avatar: Robots on the battlefield, I

    With self-detonating grenades, thinking bullets and robot warriors, humans on the frontline could soon be a thing of the past When armies clash in the not-too-distant future, remotely operated robotic weapons will fight the enemy on land, in the air, and at sea, without a human soldier anywhere on the battlefield. The first robotic systems are already being used by the Israel Defense Forces (IDF) and other armies across the world, and only budgetary constraints seem to be keeping science fiction from becoming reality.

  • Laws of physics cast doubt on Santa's ability to carry out mission

    Santa has 31 hours to visit 378 million Christian children; at the rate of 3.5 children per household, and assuming at least one good child per home, this comes to 108 million homes; if each child receives no more than a medium sized Lego set (two pounds), the sleigh would be carrying more than 500 thousand tons, not counting Santa himself; Santa would thus need at least 360,000 Reindeer to pull the sleigh; since Santa must visit 108 homes in 31 hours, he will have to travel at 650 miles per second — 3,000 times the speed of sound; at that speed, the lead pair of Reindeer would absorb 14.3 quintillion joules of energy per second each and vaporize – indeed, the entire Reindeer team would be vaporized within 4.26 thousandths of a second; Santa himself would be subjected to forces of 17,500 G’s; a 250 pound Santa (which seems ludicrously slim) would be pinned to the back of the sleigh by 4,315,015 pounds of force, and be crushed

  • Santa's sleigh of the future

    GE engineers concluded that Santa’s huge carbon footprint should be reduced; the designed a new sleigh, which includes ceramic matrix composites (CMCs) used within the sleigh blades to enable efficient flight, GE’s Trip Optimizer on the dashboard to improved navigation, and icephobic coatings to prevent ice build up; the sleigh comes with a 500GB holographic disk for Santa to store his lists

  • Large dams linked to more extreme weather patterns

    A new study looked at the magnitude of the biggest storms near 633 of the world’s largest dams before and after construction; they found that in many places the level of precipitation in the most extreme rainfall events grew by an average of 4 percent per year after a dam was built, with the relationship especially strong in semi-arid regions

  • Tadpole-shaped dirigible to help in communication, surveillance missions

    Florida company shows unmanned dirigible which will fly at 65,000 and 70,000
    feet; the “Stratellite” will use similar technology to the that used by the
    Graf Zeppelin in the 1930s; homeland security applications include vessel
    tracking and cargo container surveillance; littoral (shore-proximate)
    surveillance for ports, waterways, coastal trails, and urban environments;
    ancillary border surveillance activity, and more

  • DARPA scientists seeking lightning on tap

    DARPA is seeking proposals for how to create lightning on demand; agency says the purspose is to protect property and other assets from lightning damage, or “advances in… science relating to lightning”

  • NICTA gets AU$1.01 million for advanced video surveillance system at Port of Brisbane

    R&D body developing advanced system to help ports monitor activities in their locations; the Port of Brisbane is 110 km long and will host around 40 to 60 cameras; the movement of boats will be visible in the system along with the cargo they are carrying and tidal/wind information.

  • Japanese department store offers robots that look like their buyers

    Acting on the insight that some people can never have enough of themselves, a Japanese department store chain now offers robots that look like their buyers; for $225,000, interested individuals can have a robot designed to look like their identical twin

  • Handheld touch screen device may lead to mobile fingerprint ID

    The FBI’s Hostage Rescue Team wanted to replace the 20-pound rugged laptop plus fingerprint scanner their hostage rescue teams lug around with a smaller and lighter device; NIST researchers develop one

  • SRI to open new facility in Tampa, Florida

    California-based SRI will tomorrow open a new research facility in Tampa, Florida; the company says that the many organizations in the area doing marine research will help it in developing maritime security technologies – among them underwater sensors to improve security at U.S. ports, which the company describes as the “soft underbelly of the soft underbelly” of the United States; SRI is also active in luring other technology companies to the Tampa area for the purpose of creating a technology cluster there.

  • Scientists seek homes in the Seattle area in which to install quake monitors

    Scientists want to install seismic monitors in homes in the Seattle area to measure ground-shaking; with detailed information on the way the ground shakes in a particular spot, it may be possible to design buildings tailored to their exact locations; the instruments also will help construct “shake-maps” to pinpoint areas of heaviest damage after major earthquakes

  • New pipe-inspection technology detects leaks in aging pipes

    An aluminum ball slightly larger than a softball travel through hundreds of miles of water pipes and water mains; equipment inside the ball picks up the hissing sounds of any leaks, and the data are then wirelessly transmitted to a computer; after the pipe is drained, workers push the cart, which resembles a steel bike, through the pipe, and electromagnetic coils attached to a computer on the cart detect the location of the leak
