• Scientists: More than 4 million barrels of oil entered Gulf

    Scientists conclude that following the 20 April explosion of BP’s Deepwater Horizon well, 4.4 million barrels of oil spilled into the Gulf of Mexico; knowing the total volume of oil is critical to understanding how much oil could be lurking in the Gulf and nearby marshes — a highly contentious issue

  • Worldwide groundwater depletion rate accelerating

    In recent decades, the rate at which humans worldwide are pumping dry the vast underground stores of water that billions depend on has more than doubled; if water was siphoned from the Great Lakes as rapidly as water is pumped out of underground reservoirs, the Great Lakes would go bone-dry in around 80 years

  • 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

  • Police warm to predictive analysis crime fighting tools

    Memphis made an 863 percent return on its investment in Blue CRUSH — a predictive analysis crime fighting effort; the ROI was calculated using the percentage decline in crime and the number and cost of additional cops that would be needed to match the declining rate; Memphis has paid on average $395,249 a year on the Blue CRUSH initiative, including personnel costs, for a $7.2 million return; MPD operates on a $255.9 million annual budget

  • Multi-touch control search-and-rescue robot swarms

    The new Dream controller for Microsoft Surface could help speed up search-and-rescue operations; . when disaster strikes, search-and-rescue teams must quickly gather and assimilate the data needed to find survivors; a team of robots can help scout out for persons stuck in rubble or create new maps of the landscape; first responders, though, need ways to control those robots, and process incoming information quickly

  • A first: a Master's degree in infrastructure protection

    Ottawa’s Carleton University has unveiled a first-of-its-kind degree program: a Master of Infrastructure Protection; the program was launched last week, is offering a unique mix of courses related to engineering and national security policy; the aim is to educate infrastructure designers and engineers about policy-related issues, and policy makers about the design and engineering of the interconnected systems that form Canada’s economic and societal backbone

  • 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

  • Geoengineering may affect different regions differently

    Geoengineering approaches would succeed in restoring the average global temperature to “normal” levels, but some regions would remain too warm, whereas others would “overshoot” and cool too much; in addition, average rainfall would be reduced

  • Using bacteria to create self-healing concrete

    Cement production has an impact on the environment as it is very energy intensive, accounting for about 7 percent of the total anthropogenic atmospheric CO2 emissions; in addition to the energy consumption from production and transportation, air pollution, as well as land use and impacts on the landscape from related mining activities are also matters of concern; means of increasing the service life of concrete structures would make the material not only more durable, but also more sustainable — and researchers find that embedding certain bacteria in the concrete promises to do just that

  • University lab tech's suicide by cyanide prompts safety fears

    A Northeastern University lab technician stole cyanide from the lab, which she then used to kill herself; suicide raises public safety fears over easy access to deadly chemicals; one terrorism expert, though, says that many incidents of dangerous chemicals stolen from college labs are used by the thief against themselves and not others; “It’s the jilted lover, the disgruntled employee, it’s the suicide not the suicide attack”

  • 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

  • In era of tighter budget, simulation-based training becomes popular

    Training is invaluable, but first responder and emergency management agencies around the country are finding their budgets tighter than ever, and it is becoming increasingly difficult to conduct large-scale training exercises; the solution: simulation-based training

  • TSA: international trainees to be vetted only once annually

    TSA says it will require foreign pilots to submit to a vetting process only once annually, regardless of the number of training events or variety of training organizations used; the change should reduce the bureaucratic burden on the pilots, training outfits, and the TSA itself
