• Transforming deadly chemicals into harmless dirt

    Destroying bulk stores of chemical warfare agents is a challenge for the U.S. and international community. Current methods of eradication, such as incineration or hydrolysis, are not fully agnostic, require significant amounts of water and create hazardous waste that requires further processing. DARPA’s Agnostic Compact Demilitarization of Chemical Agents (ACDC) program recently awarded two contracts to develop prototypes of a transportable disposal system able to convert dangerous chemicals into safe output, such as harmless soil, using minimal consumables and creating no hazardous waste.

  • Climate-induced disasters linked to food security across time and place

    Teams of researchers in the American Southwest and North Atlantic Islands have found that historic and prehistoric peoples in these regions who had created vulnerabilities to food shortfall were especially susceptible to impacts from climate challenges. Their “natural” disasters were human made in conjunction with climate challenges.

  • U.K.: Economic costs from flooding could reach £1.5bn, reduce GDP growth

    Economic losses caused by the flooding which has devastated parts of Britain in the past few days could exceed 1.5 billion pounds, and shave 0.2-0.3 percent off GDP growth overall in the first quarter of 2016. Insurers will likely shoulder the bulk of the burden after first Storm Desmond and then Storm Eva saw waters swamp large swathes of the country.

  • U.K. government rejected flood warnings from own advisers

    Critics charge that the U.K. government was warned by both the government’s own climate change experts and outside consultants that there was a need to take urgent action to protect the increasing number areas in Britain which are becoming susceptible to flooding, but that the government rejected the advice. Despite the urging of its own climate experts, the U.K. government in October, just a few weeks before the devastating flooding in Cumbria, decided not to develop comprehensive strategy to address flood risk.

  • Climate change losses for Southeast Asia well above previous estimate: ADB

    Economic losses from the impacts of climate change in Southeast Asia could be 60 percent higher than previously estimated, reducing the region’s gross domestic product (GDP) by up to 11 percent by 2100, according to a new Asian Development Bank (ADB) study. The analysis is an update to a 2009 ADB report that estimated a 7 percent annual reduction in economic output due to climate change.

  • Pairing seismic data, radionuclide fluid-flow models to detect underground nuclear tests

    Underground nuclear weapon testing produces radionuclide gases that may seep to the surface, which is affected by many factors. These include fractures in the rock caused by the explosion’s shock waves that create pathways for the gas to escape plus the effect of changes in atmospheric pressure that affect the gases’ movement. Scientists have developed a new, more thorough method for detecting underground nuclear explosions (UNEs) by coupling two fundamental elements — seismic models with gas-flow models — to create a more complete picture of how an explosion’s evidence (radionuclide gases) seep to the surface.

  • Locust-inspired robot traverses rocky terrain, assists in search and rescue

    Since the 1980s, advanced robotic platforms have provided assistance to crisis intervention teams in the wake of man-made and natural disasters. The objective of such robots, in various sizes and shapes, has been to intervene where humans cannot and send life-saving data to rescue teams in the field. A new, locust-inspired robot, can jump eleven feet high — more than twice the height of similar-sized robots — and cover a horizontal distance of 4.5 feet in one leap. The researchers believe the robot will perform well in search-and-rescue missions and in reconnaissance operations in rough terrain.

  • The believers: String theory explains Santa Claus

    Some argue that the laws of physics should prevent Santa Claus from delivering all his gifts and that Santa would burn up in the atmosphere if he tried. The Norwegian Internet magazine, forskning.no, has put together a team of four top researchers to look into the case, and the panel’s conclusion is clear: Santa can do the job and Christmas is saved.

  • The skeptics: Laws of traditional physics would foil Santa's effort to carry out mission

    Santa has 31 hours to visit 378 million Christian children; at the rate of 3.5 children per household. Assuming at least one good child per home, this comes to 108 million homes. If each child receives no more than a medium sized Lego set (two pounds), the sleigh would be carrying more than 500 thousand tons of cargo, not counting Santa himself. Santa would thus need at least 360,000 Reindeer to pull the sleigh. Since Santa must visit 108 million homes in 31 hours, he will have to travel at 650 miles per second — 3,000 times the speed of sound, but at that speed, the lead pair of Reindeer would absorb 14.3 quintillion joules of energy per second each and vaporize — indeed, the entire Reindeer team would be vaporized within 4.26 thousandths of a second. Santa himself would be subjected to forces of 17,500 Gs. A 250 pound Santa (which seems ludicrously slim) would be pinned to the back of the sleigh by 4,315,015 pounds of force, and be crushed.

  • U.S., Israel to co-develop technologies for first responders

    Some $12 million will be funneled to collaborative Israeli-American projects for the development of advanced technologies for first responders over the next three years. The agreement brings together the Israeli Ministry of Public Security and the U.S. Department of Homeland Security in a drive to better equip and prepare both countries’ national rescue forces including fire, police, and first-aid units. Each side will invest equally in the project.

  • Making the power grid more resilient, flexible

    “The biggest and most complex machine ever built by humankind” – this is how one researcher describes the U.S. power grid. A research team has been charged with the formidable task of transforming that big and complex machine from the inside out. Inverters convert DC (direct current) electricity to AC (alternating current) electricity, the kind that forms the basis of today’s power grid. To integrate more inverter-based distributed generation into the grid, the researchers are developing a dynamic distribution system (DDS) that supplements centralized power plants, instead of replacing them.

  • Idaho to become U.S. geothermal research hot spot

    For all the talk about energy shortages, the fact is the Earth is giant ball of energy that has been producing heat ever since the solar system was formed billions of years ago. The temperature at the core — 6,000 degrees Celsius — is roughly the same as the surface of the sun. All that heat radiates outward through the Earth’s mantle and crust. Less than 1 percent of the electricity in the United States comes from geothermal sources, and energy specialists believe that geothermal power should make a much greater contribution to U.S. electricity. A new consortium plans to pump water into the rock about 8,000 to 12,000 feet deep, fracture the rock and capture heat, then bring heated, pressurized water back to the surface to generate energy.

  • Terrorism pushes liberals to think more like conservatives

    Liberals’ attitudes in the United Kingdom toward Muslims and immigrants became more like those of conservatives following the 7 July 2005 bombings in London, new research shows. Data from two nationally representative surveys of British citizens revealed that feelings of national loyalty increased and endorsement of equality decreased among political liberals following the terrorist attack. “Our findings show that terrorism shifts public attitudes towards greater loyalty to the in-group, less concern with fairness, and greater prejudice against Muslims and immigrants, but it seems that this effect is stronger on those who are politically left-leaning than those who are right-leaning,” explained one of the researchers.

  • No rise in anti-Muslim sentiment in U.K. in wake of Paris attacks: Poll

    Last month’s terrorist attacks in Paris appear not to have led to a rise in anti-Muslim sentiment in Britain, a new study has shown. The new research comes amid concerns that Western public opinion may grow more hostile toward Muslims, as evidenced by the success of the Front National in the first t round of France’s regional elections three weeks ago, and the apparent popularity of Republican presidential candidate Donald Trump, who has called for a ban on Muslim immigration to the United States.

  • U.S. reliance on nonfuel mineral imports increasing

    Key nonfuel mineral commodities that support the U.S. economy and national security are increasingly being sourced from outside the U.S., according to a new U.S. Geological Survey report. Over the past sixty years, there has been an increase in the number and diversity of nonfuel commodities that the United States imports as well as the extent to which the United States is import reliant.
