• Cold water-pumping submarines to reduce ferocity of typhoons

    Typhoon intensity tends to remain level when ocean surface temperatures are high; reduction in the surface-water temperature would reduce the ferocity of the typhoon; Japanese company receives a patent for a typhoon-intensity-reduction system based on submarines pumping cold water from the depth of the sea to the surface in the typhoon’s path

  • U.K. aerospace students to build human-powered aircraft

    Final year aerospace engineering students at the University of Bath, too, will be following in the footsteps of Leonardo da Vinci, designing and building a human-powered aircraft as part of their degree

  • Space plane that takes off from runway ready in 10 years

    An unpiloted, air-breathing space plane that takes off from an airport runway and carries up to thirty passengers could be ready to fly in ten years; it will cost an estimated $12 billion to develop the space plane, and an additional $10 million per launch, compared to the approximately $150 million cost of a rocket launch; the company predicts that a trip to orbit for two weeks would cost tourists about $500,000 per seat

  • A first: human-powered ornithopter achieves sustained flight

    Leonardo da Vinci sketched the first human-powered ornithopter in 1485, but the idea had to wait until 2 August 2010 to be realized; aviation history was made when the University of Toronto’s human-powered aircraft with flapping wings became the first of its kind to fly continuously; the wing-flapping device sustained both altitude and airspeed for 19.3 seconds, and covered a distance of 145 meters at an average speed of 25.6 kilometers per hour

  • New TNT detector 1,000 more sensitive than sniffer dogs

    Israeli researchers develop an explosives detector that can detect extremely small traces of commonly used explosives in liquid or air in a few seconds; the device is a thousand times more sensitive than the current gold standard in explosives detection: the sniffer dog

  • Spray-on clothes to help injured soldiers

    Researchers develop spray-on clothing which could be used by people in a hurry, but also by first responders and soldiers in the field for spray-on sterilized bandages; drugs may be added to the spray-on bandage to help a wound heal faster

  • Insect-size air vehicles to explore, monitor hazardous environments

    High-performance micro air vehicles (MAVs) are on track to evolve into robotic, insect-scale devices for monitoring and exploration of hazardous environments, such as collapsed structures, caves and chemical spills

  • Revolutionary horizontal space launch nears

    Scientists examine a proposal that calls for a wedge-shaped aircraft with scramjets to be launched horizontally on an electrified track or gas-powered sled; the aircraft would fly up to Mach 10, using the scramjets and wings to lift it to the upper reaches of the atmosphere where a small payload canister or capsule similar to a rocket’s second stage would fire off the back of the aircraft and into orbit; the aircraft would come back and land on a runway by the launch site

  • Sandia Labs developed an IED-disabling water-blade device

    A device developed by Sandia National Laboratories researchers that shoots a blade of water capable of penetrating steel is headed to U.S. troops in Afghanistan to help them disable deadly IEDs; the portable clear plastic device is filled with water and an explosive material is placed in it that, when detonated, creates a shock wave that travels through the water and accelerates it inward into a concave opening; when the water collides, it produces a thin blade

  • New helmets to make soldiers more alert, reduce stress, pain

    New helmet to enhance U.S. soldiers’ cognitive abilities, improving long-term alertness, and reducing stress, anxiety, and pain; DARPA-funded research looking to equip helmets with noninvasive technology for “transcranial pulsed ultrasound,” which can remotely stimulate brain circuits

  • Northeastern to build homeland security research center

    A $12 million gift from an alum will allow Northeastern University to build a homeland security research facility on its Burlington campus; the George J. Kostas Research Institute for Homeland Security will be designed to Department of Defense specifications so Northeastern can gain clearances to conduct secure research on areas pertaining to national security, including cryptography, data security, information assurance, explosives detection, and energy harvesting

  • Fake chips from China threaten U.S. military systems

    To withstand the rigors of battle, the Defense Department requires the chips it uses to have special features, such as the ability to operate at below freezing temperatures in high-flying planes; because it pays extra for such chips, experts say, the Defense Department has become a prime target for counterfeiters, most of them Chinese companies; from November 2007 through May 2010, U.S. Customs officials said they seized 5.6 million bogus chips — yet many more are finding their way into the United States and even the military

  • Is the U.S. military interested in a Kiwi Jetpack?

    Kiwi company claims the U.S. military is interested in its Jetpack (not really a jetpack, but personal ducted-fan aircraft too heavy to be lifted by its user); the company made the headlines in the spring by saying it was about the sell the first commercial jetpack for $75,000 a piece; the price has since gone up a bit, to $140,00 a unit, but the company says that 1,600 people have “expressed interest” in buying the Jetpack

  • Lasers will protect helicopters from heat-seeking missiles

    A Michigan company using off-the-shelf telecommunications fiber optics to develop rugged and portable mid-infrared supercontinuum lasers that could blind heat-seeking weapons from a distance of 1.8 miles away; the technology will be used to protect combat helicopters from heat-seeking missiles

  • Technical problems grounds homemade Danish space rocket

    The launch of the first homemade rocket into space failed Sunday owing to technical difficulties; the two Danish inventors who used private funds to develop the 9-meter, 1.6-ton prototype hope to send a person into space within three or four years, which would make Denmark only the fourth nation to do so
