  • Emulating stingray movement to build next generation of submarines

    Stingrays swim through water with such ease that researchers believe that emulating the fish’s unique way of swimming could improve deep-sea vehicles’ agility and fuel efficiency. “Most fish wag their tails to swim. A stingray’s swimming is much more unique, like a flag in the wind,” says one researcher.

  • Insects’ way of flying inspires design of tiny flying robots

    Researchers have identified some of the underlying physics that may explain how insects can so quickly recover from a stall in midflight — unlike conventional fixed wing aircraft, where a stalled state often leads to a crash landing. The analysis improves the understanding of how insects fly and informs the design of small flying robots built for intelligence gathering, surveillance, search-and-rescue, and other purposes.

  • Advanced police surveillance technologies pose significant privacy concerns

    Much of the attention on surveillance in the media focuses on the National Security Agency (NSA), but there is not a lot of scrutiny on local domestic surveillance. In 1997, about 20 percent of police departments in the United States used some type of technological surveillance. By 2007, that number had risen to more than 70 percent of departments. Experts in criminal law and information privacy warn that the widespread use of advanced surveillance technologies such as automatic license plate readers, surveillance cameras, red light cameras, and facial recognition software by state and local police departments, combined with a lack of oversight and regulation, have the potential to develop into a form of widespread community surveillance, which ought to pose significant privacy concerns to law-abiding citizens.

  • U.S. Navy dominates competition for number, quality of patents

    The IEEE evaluated more than 5,000 organization patent portfolios, across the seventeen industry sectors evaluated in its scorecard, for the number of patents issued as well as the growth, impact, originality, and general applicability across their respective portfolios. A laser with the potential to jam heat-seeking missiles and sniff out chemicals was one of 358 technologies patented by the U.S. Navy in 2012, helping the service dominate the government category in an annual ranking of patent portfolios published 23 October. It is an achievement the Navy has held since the scorecard added the government category in 2008.

  • Ann Arbor to offer residents networked, driverless cars by 2021

    By 2021, Ann Arbor could become the first American city with a shared fleet of networked, driverless vehicles. This is the goal of the Mobility Transformation Center, a cross-campus University of Michigan initiative that also involves government and industry representatives.

  • DoD ends ambitious blimp program

    The Department of Defensehas decided to end its Long Endurance Multi-Intelligence Vehicle (LEMV) project.The blimp was supposed to fly for as long as three weeks at a time, gather intelligence using 2,500 pounds worth of the most advanced cameras, sensors, and other intelligence technology. Operating at an altitude of 20,000 feet, the airship was designed to withstand enemy fire with its blend of fabrics, including kevlar. The Pentagon spent $297 million on the airship, but last month sold it back to one of the contractors which built it for $301,000.

  • Wireless device converts wasted energy into electric power

    Using inexpensive materials configured and tuned to capture microwave signals, researchers have designed a power-harvesting device with efficiency similar to that of modern solar panels. The device wirelessly converts the microwave signal to direct current voltage capable of recharging a cell phone battery or other small electronic device.

  • UAV developer CyPhy Works raises $7 million to build flying robots

    Danvers, Massachusetts-based CyPhy Works, a developer of advanced UAVs, the other day announced the close of a $7 million financing round led by Lux Capital, with participation from General Catalyst Partners, Felicis Ventures, and several undisclosed angel investors. As part of the financing, Lux Capital Partner Bilal Zuberi will join the CyPhy Works board of directors. The company says it targets 24/7 “persistent” operations.

  • “Hybrid” nuclear plants could make a dent in carbon emissions

    Combining nuclear with artificial geothermal, shale oil, or hydrogen production could help slow climate change, study shows. MIT’s Charles Forsberg proposes marrying a nuclear powerplant with another energy system, which he argues could add up to much more than the sum of its parts.

  • Pyreos, ultra‐low power consumption IR sensor specialist, secures $4 million investment

    Edinburgh, Scotland-based Pyreos Limited, a specialist in ultra‐low power consumption infrared sensor technology, the other day announced plans for international expansion after securing a further funding round of $4 million. It is possible to use Pyreos sensor arrays in many applications, among them border security, where they can identify human movement at distances of several kilometers.

  • Cool technology from DHS

    The U.S. Department of Homeland Security (DHS) employs more than 240,000 people in a variety of areas and activities, from border security and aviation to emergency response and cybersecurity, plus everything in between. Many may not be aware of the fact that DHS has also been busy developing some cool, high-tech, life-saving gear to protect people before, during, and following disasters and emergencies.

  • Detecting threats in a crowd

    Around a military camp situated close to a built-up area there are always people moving about. Scientists at FOI, the Swedish Defense Research Agency, have created a multi-sensor system designed to be able to detect threats by identifying unusual patterns of movement involving individuals or groups.

  • Planet’s arable land rapidly degrading

    Great civilizations have fallen because they failed to prevent the degradation of the soils on which they were founded. The modern world could suffer the same fate. A new study describes how the productivity of many lands has been dramatically reduced as a result of soil erosion, accumulation of salinity, and nutrient depletion.

  • U.S. policy should encourage foreign Ph.D. students to stay: study

    Attracting more talented foreign students to study at U.S. universities and encouraging them to launch entrepreneurial ventures here could help “revitalize innovation and economic growth” in this country, three economists conclude in a new study. The researchers have found that high-performing foreign-born Ph.D. students improve the “creation of knowledge” in U.S. universities. When knowledge is created, it tends to drive entrepreneurial investment and economic growth.

  • Best way to stop a killer asteroid? Form a committee

    The United Nations (UN) has adopted several recommendations of a new asteroid defense plan, the first steps in preventing Earth from being struck by an asteroid. The recommendations were a response to an asteroid strike earlier this year in Chelyabinsk, Russia. This object injured thousands and was around seventeen meters across. We have only found 1 percent of these “killer” asteroids, meaning there are hundreds of times more out there than we know of. One of them, sooner or later, will have our name written on it. For a global threat we need a global response, as well as a global share of the blame if it goes wrong.
