• Modeling shows limited spread of Fukushima's radioactive release in ocean

    Daily computer simulations are suggesting that, so far, the hazardous radioactive materials being released into the sea by the Fukushima nuclear plants are still largely restricted to areas near the coast; the powerful Kuroshiro current — the Pacific’s version of the Gulf Stream — tends to block contaminated seawater from flowing southward toward Tokyo Bay while picking up little contamination itself

  • New device uses sniffer bees to detect explosives

    The unassuming honeybees have a hidden talent — an even keener sense of smell than anyone first expected — which could make them one of the U.K.’s most ruthless and worst-feared weapons against terrorism; researchers developed a portable handheld sensor that holds thirty-six trained bees gently restrained in six cassettes inside the device; each is taught to recognize a particular odor and associate that smell with a food reward; the researchers have already trained their honeybees to detect a wide variety of explosive compounds and mixtures, including Semtex, C4, PE4, TNT, DMNB, gunpowder, and hydrogen peroxide

  • Ultra-sensitive sensor technology detects explosives, cancer

    Princeton researchers have invented an extremely sensitive sensor that opens up new ways to detect a wide range of substances, from tell-tale signs of cancer to hidden explosives; the sensor, which is the most sensitive of its kind to date, relies on a completely new architecture and fabrication technique developed by the Princeton researchers; the device boosts faint signals generated by the scattering of laser light from a material placed on it, allowing the identification of various substances based on the color of light they reflect; the sample could be as small as a single molecule

  • OSU chemist developing solution to nerve agent exposure

    Scientists are working to develop a new drug that will regenerate a critical enzyme in the human body that “ages” after a person is exposed to deadly chemical warfare agents; the drug will counter the effects of Tabun, VX, VR, Sarin, Soman, Cyclosarin, and Paraoxon, all of which take on a similar molecular structure upon aging

  • High School students build Florida police a robot

    In Rockledge, Florida, the local police department just purchased a new remote controlled robot that is equipped with a video camera, night vision, a gas canister launcher; rather than spending hundreds of thousands of dollars to purchase the robot from a defense company, the Rockledge police department turned to local high school students; the robot can handle any terrain, launch grenades, and is strong enough to drag a person; it is also outfitted with a speaker and a microphone to enable two way communications in addition to a police throw phone that can be deployed during hostage negotiations; the robot cost $6,000 whereas similar professionally made robot would have cost more than $100,000

  • Heavy snows divert Colorado River water shortage, for now

    This winter, heavy snowfall in Utah, Colorado, and Wyoming have helped to avert a water crisis along the Colorado River; after an eleven year drought in the region, residents have begun to worry about impending water shortages; the Colorado River supplies nearly thirty million people in seven states with drinking water as well as Mexico; the heavy snows could bring only a brief moment of respite; with demand exceeding supplies and with each year bringing less water, there is potential for a future disaster; if supplies continue to decline, water deliveries will be reduced when Lake Mead’s water level drops below 1,075 feet; as of 1 February, Lake Mead’s water level was at 1,091feet

  • Waste ash from coal could save billions in repairing U.S. bridges and roads

    The more than 450 coal-burning electric power plants in the United States produce about 130 million tons of “flyash” each year; before air pollution laws, those fine particles of soot and dust flew up smokestacks and into the air; power plants now collect the ash; researchers say that coating concrete destined to rebuild America’s crumbling bridges and roadways with some of the millions of tons of that left-over ash could extend the life of those structures by decades, saving billions of dollars of taxpayer money

  • Artificial clouds to help keep 2022 World Cup cool

    Tiny Qatar will be the host of the 2022 Soccer World Cup; trouble is, temperatures in June and July can reach up to 50C (122F), leading to worries about the health effects of players and spectators; Qatari researchers say they have a solution: artificial clouds; the clouds are made from a lightweight carbon structure, and carry a giant envelope of material containing helium gas; four solar-powered engines move the structure via remote control

  • Rising seas and coastal risks

    Most scientists believe that melt water from glaciers, the Greenland ice sheet, and possibly the West Antarctic ice sheet, along with thermal expansion from warming oceans, will raise sea levels by one-half to one meter (1.6 to 3.2 feet) over the next century and by one meter to two meters (6.5 feet) over the next 200 years; if sea level rises by a meter, “we will see higher tides, higher tidal velocities and tidal inundation every day,” says one expert; “And we’ll have a different shoreline”

  • China raises rare Earth elements production

    China has about 30 percent of rare earths deposits but accounts for 97 percent of global production; the Ministry of Land and Resources said Thursday that this year’s production quota of rare earths will be 93,800 tons, an increase of about 5 percent over 2010

  • Jersey community college first to offer homeland security degree

    Ocean County College is the first community college in New Jersey to begin offering students an associate’s degree in homeland security studies; as police departments across the United States have seen their budgets slashed, it has become increasingly difficult for recent graduates hoping to find jobs as police officers; the program encourages students to pursue law enforcement opportunities with DHS; currently there is a need in the private and public sector for qualified personnel, but a shortage of talented individuals; the program will introduce homeland security to students and if they are interested in a position with the government must receive a bachelor’s degree from a four year college

  • Corruption in academic accreditation

    Little-known colleges, most unaccredited, exploit Byzantine federal regulations, enrolling almost exclusively foreign students and charging them upward of $3,000 for a chance to work legally in the United States; they flourish in California and Virginia, where regulations are lax, and many of their practices are shoddy — for instance, holding some classes on only three weekends per semester; these colleges usher in thousands of foreign students and generate millions of dollars in profits because they have the power, bestowed by the U.S. government, to help students get visas

  • UN warns of potential food crisis

    A UN Food and Agriculture Organization official warned that countries are not doing enough to increase food production to meet rising demand and that the world could be headed for a global food crisis; global food production must rise by 70 percent in order to meet the estimated demand for food; food prices have already soared in recent months and in 2010 food prices increased by 25 percent; rising prices sparked food riots in Egypt and Tunisia, which contributed to the overthrow of their governments; large disasters and droughts have significantly reduced crop yields across the world; as supply has fallen, demand has spiked due to population growth and increased use of food to manufacture biofuels

  • Lockheed developing autonomous and covert rover

    A surveillance robot aims to operate around humans without being detected by them; the machine uses a laser scanner to builds a 3D computer model of its surroundings and uses a set of acoustic sensors to distinguish the proximity and direction of footsteps

  • After EPA fine, mining company building $200 million water treatment plant

    America’s largest underground coal mining company, Consol Energy, is constructing a $200 million water treatment plant in West Virginia, after being fined $5.5 million by the Environmental Protection Agency (EPA); in 2009 discharge from Consol’s mining operation caused a toxic golden algae bloom that killed aquatic life along thirty miles of Dunkard Creek; the advanced waste water treatment plant will be the largest facility in Appalachia; the plant will be capable of treating 3,500 gallons of water per minute and will remove more than forty-three tons of dissolved solids, including eleven million pounds of chloride
