• DHS considers merging infrastructure protection, cybersecurity units

    The connectedness between the U.S. critical infrastructure assets and the Internet steadily increases, so the missions of DHS’s infrastructure protection and cybersecurity units become more intertwined as well; the department considers merging the two units

  • Gulf oil spill prompts procedure reassessment in U.K.

    The United Kingdom has created a new body — the Oil Spill Prevention and Response Advisory Group (OSPRAG) — tasked with learning the lessons of the Gulf oil spill and applying them to the U.K. off-shore drilling sector

  • Oregon town plans first tsunami-resistant building on stilts

    Geological findings in recent years suggest there is a one-in-three chance that in the next half century a mega-earthquake will tear the seafloor apart off the Oregon Coast; huge waves would surge onto coastal communities in as little as fifteen minutes; an Oregon city plans tsunami-resistant buildings on stilts

  • Berkeley quake demonstration shows bridge safety ideas

    Researchers demonstrate new bridge design that can withstand powerful earthquakes; the design concept relies on building segmented bridges with seismic isolators between the segments; the design would be particularly useful for long stretches of elevated freeways and high-speed rail lines that often run on elevated tracks

  • Crack-proof concrete developed

    Researchers develop crack-proof concrete; the construction industry has spent decades looking for materials that would not crack when they are used to repair and reinforce older materials, because even hairline cracks can let in pollutants and start disintegrating the concrete; BASF engineers offer a solution

  • U.S. to expand freight congestion tracking initiative

    The worst traffic bottleneck in the United States is the I-290 interchange with I-90 and I-94 in Chicago, where the average speed at 5 p.m. drops to 15 mph; the average peak hour speed is 23 mph, and the average non-peak hour speed is only 33 mph; data gathered from trucks identifies bottlenecks, and could help steer infrastructure planning

  • Grid in western U.S. can handle more renewable energy

    A new study says 35 percent of electricity in the western United States could come from solar and wind — without expensive new backup power plants; the findings provide a strong counterargument to the idea that the existing power grid is insufficient to handle increasing amounts of renewable power

  • Self-healing concrete developed

    University of Rhode Island researchers develop a new type of self-healing concrete that promises to be commercially viable and have added environmental benefits; a microencapsulated sodium-silicate healing agent is embedded directly into a concrete matrix; when tiny stress cracks begin to form in the concrete, the capsules rupture and release the healing agent into the adjacent areas

  • Italian-Russian reactor could be the first to achieve self-sustaining fusion

    As the interest in alternatives to fossil fuels grows, so does the interest in nuclear fusion; a Russian-Italian project will build a self-sustaining fusion reactor based on a design by an MIT scientist; the design employs a doughnut-shaped device which uses powerful magnetic fields to produce fusion by squeezing superheated plasma of hydrogen isotopes

  • Deep-water oil spills do most of the damage deep down

    Oil spills like the one in the Gulf do most of their damage in the deep; the oil visible on the surface accounts for only 2 percent of the oil spilling into the Gulf; most of the oil remains submerged in the form of droplets that only slowly make their way to the surface

  • Fears grow that Gulf oil could strike Florida

    Worries grow over the ecological and economic impact of the huge oil spill, with the most recent fears focused on its possible spread into a “loop current” that could carry the pollution to the Florida Keys and nearby tourist beaches; the U.S. government has already extended fishing closure to nearly 20 percent of the Gulf because of the contamination of harvested seafood

  • The day of transportable, refrigerator-size nuclear reactor nears

    The need for more energy and the growing interest in energy not based on fossil material have led to a revival of interest in nuclear power; there is a competition afoot among several companies for designing and building — and receiving a operation license for — a refrigerator-size nuclear reactor; the $50 million, 25-megawatt unit is transportable by truck, and would put electricity into 20,000 homes

  • BP's emergency "plan" for the Gulf discusses impact on "seals, sea otters and walruses"

    BP’s 582-page emergency-response never anticipated an oil spill as large as the one now gushing on the floor of the Gulf of Mexico; a closer reading shows the document was not much than a boilerplate, cut-and-paste job used by BP from region to region; in a section titled “Sensitive Biological & Human-Use Resources,” the emergency plan lists “seals, sea otters and walruses” as animals that could be impacted by a Gulf of Mexico spill — even though no such animals live in the Gulf; the plan was approved in July by the federal Minerals Management Service (MMS), a toothless agency accused by lawmakers of being in the pocket of the oil industry

  • BP oil leak "much bigger" than official estimates'

    BP first asserted that the amount of oil its well releases into the Gulf is about 1,000 barrels daily; following the U.S. National Oceanic and Atmospheric Agency’s (NOAA) initial estimates, that figure has been increased to 5,000 barrels; ocean scientists and engineers now say that amount of oil released daily is more likely to be between five times and 14 times that — about 25,000 to 80,000 barrels a day

  • Scientists discover huge oil plumes deep in Gulf of Mexico; worry for marine life

    The news from the Gulf get worse: Scientists discover giant plumes of oil in the deep water of the Gulf of Mexico; one of the plumes was ten miles long, three miles wide, and 300 feet thick; the plumes are depleting the oxygen in the Gulf, prompting fears that the process could eventually kill much of the sea life near the plumes
