  • Past as prologue: Insights from past natural disasters relevant today

    The increasing frequency and intensity of natural disasters constitute a daunting challenge to modern society, which is characterized by a heavy infrastructure and increasing population density. Until now, coping with natural disasters has involved expensive state intervention and technology-aided approaches, but researchers believes that the past contains a wealth of unexploited resources which could also provide solutions to the problems communities face when dealing with need to cope with, and recover from, natural disasters.

  • Rochester, Minn. wants to stop crime before it happens

    The Rochester Police Departmentin Rochester, Minnesota is using IBM’s Infosphere Identity Insightto predict, and combat, crime. InfoSphere Identity Insight is used to identify frequent crime offenders, and even when multiple false identifications belonging to one individual are stored on record, the associated relationships of those identities could lead to the correct individual.

  • The Ergonomics of bomb-making at sea

    In an effort to stem work-related injuries and speed the assembly of munitions aboard aircraft carriers, the Office of Naval Research (ONR) spearheaded the development of a more efficient and ergonomic way to build bombs at sea. The ONR-sponsored improvements will allow sailors to move around more freely and assemble multiple bombs simultaneously on smaller, individual stands.

  • Sequestration already eroding U.S. research capabilities

    As congressional budget leaders continue negotiations over Fiscal Year 2014 spending levels, three organizations representing the U.S. leading public and private research universities say that the results of a new survey reveal the pernicious impact of sequestration on scientific research across the country. Budget cuts have already led to fewer grants, cancelled projects, staff reductions, and reduced learning opportunities. “If Congress fails to reverse course and doesn’t begin to value investments in research and higher education, then the innovation deficit this country is facing will worsen as our foreign competitors continue to seize on this nation’s shortfall,” the leader of one of the organizations said.

  • Climate scientists say renewables are not enough

    Some of the world’s top climatologists have declared their support for nuclear energy as a complementary energy source, alongside wind and solar as energy, which would cut fossil fuel pollution and reduce the growth of global warming. The scientists say that opposing fossil fuels and promoting renewable energy sources offer but a limited solution.

  • 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.

  • Chevron contributes $1.5 million to new engineering education initiative

    Chevron has contributed $1.5 million to a new National Academy of Engineering (NAE) initiative that will provide expert, research-based guidance to those involved in overseeing engineering education in kindergarten through grade 12. The initiative will create a clearinghouse of curriculum materials and resources and connect engineering education experts with teachers, administrators, and others involved in providing engineering experiences to K-12 students.

  • Philippines prepares for worse disasters to come

    On average, the Philippines experiences about twenty typhoons a year, including three super-typhoons and many incidents of flooding, drought, earthquakes, tremors, and occasional volcanic eruptions, making the country one of the most naturally disaster-prone areas in the world. Filipino government agencies, with the help of international disaster and relief agencies, have created new strategies for disaster preparedness, response, and mitigation which may well have potential applications in other parts of the world. As the impact of climate change grows more pronounced, the Philippines is becoming a hothouse for developing new methods and systems in the growing business of disaster relief.

  • 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.

  • Sunlight-activated nanogrid breaks down pollutants in water

    Oil spills do untold damage to the environment — to the waters they pollute and to marine and other wildlife. The Deepwater Horizon spill in the Gulf of Mexico in 2010, for example, the largest accidental marine oil spill in the history of the petroleum industry, flowed unabated for three months. Typically, such oil spills are extraordinarily difficult to clean up. Soon, however, the process may become infinitely easier and ecologically friendly, the result of a new invention — “nanogrid” — a large net consisting of metal grids made of a copper tungsten oxide, that, when activated by sunlight, can break down oil from a spill, leaving only biodegradable compounds behind.

  • 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.

  • Chelyabinsk meteor explosion a "wake-up call," scientists warn

    Three new studies have revealed details of the meteor that exploded above Russian city, Chelyabinsk, in February this year. Their findings provide information about the meteor’s origin, trajectory, power and damage by the airburst (the shock wave that travelled through the air from the explosion). These findings may help to refine theoretical models about the likely frequency of such events, the potential damage they could cause and hazard mitigation strategies needed for planetary protection.

  • 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.
