• Montana floods exacerbate Exxon oil spill

    Flooding in Montana has exacerbated the effects of an oil spill and made clean up more difficult for Exxon Mobil; it is estimated that roughly 750 top 1,000 barrels of crude oil have leaked into the Yellowstone River near Billings, Montana; the pipeline has been shut down, but flooding in the area has made it difficult for clean-up crews to find the source of the leak

  • A first: Flying car cleared for road

    The U.S. Department of Transportation gave Massachusetts-based Terrafugia two important exemptions which would allow the company to offer its flying car — the Transition — to customers next year; the exemptions allow the company to use different tires and different laminated protective glass, and come on top of a 110 lb. allowance the FAA gave the company last year; these allowance and exemptions mean the flying car will not be treated as plane by the FAA, and those who fly it will not have to obtain a pilot license

  • Roving robot can rescue people, detonate bombs

    Northeastern University student-researchers have created a roving robot that can locate and rescue victims of natural disasters or participate in military missions that are too dangerous for soldiers; students created a complex algorithm that would enable the robot to locate people — or even bombs that are detonated through mobile phones

  • Japanese discovery could undermine China's rare earth dominance

    A new discovery by Japanese researchers could break China’s stranglehold over rare Earth metals; Japanese geologists say they have found large deposits of rare Earth minerals on the floor of the Pacific Ocean; it is estimated that the mud of the Pacific Ocean contains 100 billion tons of these minerals

  • Microalgae : Texas' next big cash crop

    There are an estimated 200,000 to 800,000 species of microalgae — microscopic algae that thrive in freshwater and marine systems; scientists say microalgae offers a huge, untapped source of fuel, food, feed, pharmaceuticals, and even pollution-busters; it is set to be Texas’ next big cash crop

  • New technology makes textiles permanently germ-free

    University of Georgia scientist develops a new technology that makes textiles permanently germ-free, targeting healthcare-associated infections; the new material effectively kills a wide spectrum of bacteria, yeasts, and molds that can cause disease, break down fabrics, create stains, and produce odors

  • Quake-resistant superelastic alloy developed

    Japanese scientists added a small amount of nickel to an iron-based alloy, and found that the new material can recover its original shape at any temperature from -196 to 240 degrees Celsius; the material may be used in environments that are constantly exposed to extreme temperatures, such as joints and controls in cars, planes, and spacecraft; it may also help buildings cushion stress and violent movement in earthquakes

  • Flights increase rain and snow near airports

    Areas near commercial airports experience a measurable increase in rain and snow when aircraft take off and land under certain atmospheric conditions; when planes fly through certain mid-level clouds, they force nearby air rapidly to expand and cool; this causes water droplets to freeze to ice and then turn to snow as they fall toward the ground, often leaving behind odd-shaped gaps in the clouds

  • "Sensing skin" to monitor concrete infrastructure health inexpensively

    In 2009, the American Society of Civil Engineers (ASCE) assigned the grade D to the overall quality of infrastructure in the United States and said that ongoing evaluation and maintenance of structures was one of five key areas necessary for improving that grade; civil engineers recently proposed a new method for the electronic, continual monitoring of structures

  • Farm animal disease to increase with climate change

    Researchers looked at changes in the behavior of bluetongue — a viral disease of cattle and sheep — from the 1960s to the present day, as well as what could happen to the transmission of the virus forty years into the future; they found, for the first time, that an outbreak of a disease could be explained by changes to the climate

  • Bomb-proof bag for planes' luggage compartment developed

    The blast-absorbing bag, named the Fly-Bag, features multiple layers of novel fabrics, composites, and coatings and is designed to be filled with passenger luggage and then placed in the hold of a plane; if one of the pieces of luggage inside the Fly-Bag had a bomb in it and the bomb exploded during the flight, the resulting blast would be absorbed by the bag owing to its complex fabric structure, preventing damage to the plane; fundamental to the design of the bag is the internal elastomeric coating and impregnation of fabric with Shear Thickening Fluids (STF); STFs work by increasing in viscosity in response to impact

  • Disappearing La Niña blamed for U.S. disastrous weather since January

    La Niña and El Niño are opposite extremes of a great Pacific oscillation; every two to seven years, surface waters across the equatorial Pacific warm up (El Niño) and then they cool down again (La Niña); each condition has its own distinct effects on weather; La Niña was strong in December, but disappeared in January, leaving nothing to constrain the jet stream; the jet stream took advantage of the new freedom — with disastrous results for the weather

  • New building material could help solve bridge woes

    With infrastructure in the United States rapidly aging and in need of repair, new building materials made in Maine that make bridges cheaper, lighter, and more durable could help cash starved states undertake critical infrastructure investment; using lightweight hybrid composite beams, the Maine Department of Transportation (MDOT) has just completed the largest composite bridge in the world; the new bridge is projected to last at least 100 years; the material’s weight, cost, and durability have generated a lot of interest across the country

  • High tech more effective than tax climate in driving states' economic growth

    Race-to-the-top policies are generally defined as those involving investments in education, entrepreneurship, and infrastructure; race-to-the-bottom policies involve competition among the states for jobs by using lower taxes and industrial recruitment incentives; researchers find that states with more technology classes in school, higher domain name registrations, and more people online tended to economically outperform states with a lower emphasis on technology

  • Official dispels government green procurement regulation myths

    The U.S. government owns or manages one in five acres in the United States, and is the largest domestic user of electricity; it is also one of the largest consumers of resources in the United States, purchasing on average $535 billion worth of goods each year; In 2009 President Obama issued an executive order requiring that all government agencies establish and implement plans to increase their environmental performance; speaking at the 2011 Security Industry Association’s (SIA) Government Summit to an audience of security professionals, a government official sought to clarify myths surrounding the government’s new green procurement regulations and assured government service providers that the rules would not drastically affect a company’s existing practices
