• Innovative hydroelectric solution harvests power from water flowing through municipal pipes

    An innovative solution has made it so dams do not have to be built in order to get hydroelectricity; hydroelectric power can now be harvested from water flowing through municipal pipes; the innovation is creating energy by using existing infrastructure, as well as solving a problem in that infrastructure

  • Coastline erosion due to rise in sea level greater than previously thought

    The effects of coastline erosion as a result of rising sea-level rise can be measured by acceptable engineering tools, but such an erosion in the vicinity of inlets, such as river estuaries, has until now been underestimated – and more difficult to calculate; scientists have develop a new model to calculate this more complex erosion, making a valuable contribution to coastal management, planning, and infrastructure protection

  • Many of the U.S. 20 million manholes are in need of immediate rehabilitation or replacement

    The EPA estimates that there are about twenty million manholes in the United States – or one manhole for every 400 feet of pavement on average; many of those manholes are in serious decay or in need of immediate rehabilitation or replacement

  • Testing new pavement materials

    Scientists are trying to determine the durability of recycled materials for use in road construction; a Texas university is building a new accelerated pavement testing center, with the overall road pad at the accelerated pavement testing center could be a little bigger than a half-acre in size

  • MIT expert: “toxic” political discussions limit climate response

    In a talk at the Sandia National Lab, an MIT expert says the inability of natural and social scientists to convince political leaders that “we’re spinning a roulette wheel over climate change” puts humanity at “extreme risk,” and that the difficulties in using science to push for mitigation strategies are more political than scientific

  • As shoe-scanning devices fail, passengers continue to remove their shoes

    In the last five years the U.S. government has tested several scanning devices for detecting explosives and other weapons concealed in the shoes of airline passengers; after spending millions of dollars on these devices, TSA has concluded that the detection systems are ineffective; the result: removing shoes at security check points is going to be a part of air travel for the foreseeable future

  • In China, corruption blamed for collapse of bridges

    Since 2011 eight bridges have collapsed in China, according to the state run media, including the Yangmingtan Bridge in the city of Harbin last November; the bridge was almost 10-mile long and construction was originally estimated to take three years, but workers finished it in half the time; when the bridge collapsed, the first thing on people’s mind was corruption

  • Earthquake hazards map contains deadly flaws

    Three of the largest and deadliest earthquakes in recent history occurred where earthquake hazard maps did not predict massive quakes; scientists recently studied the reasons for the maps’ failure to forecast these quakes, and explored ways to improve the maps

  • Engineers develop electricity-free home cooling system

    Researchers are developing a solar cooling and heating system for the home which will run independently of the electricity grid and generate domestic hot water as a by-product

  • Trade-offs between water for food and for curbing climate change

    Earth’s growing human population needs fresh water for drinking and food production. Fresh water, however, is also needed for the growth of biomass, which acts as a sink of carbon dioxide and thus could help mitigate climate change. Does the Earth have enough freshwater resources to meet these competing demands?

  • As Hurricane Isaac beats on New Orleans, new infrastructure is holding up

    This week, as Hurricane Isaac was threatening to replicate the physical damage that Katrina inflicted, it has become apparent that $14 billion worth of changes and improvements in infrastructure, planning, and emergency response procedures have given the city of New Orleans and the Gulf states the ability to withstand the worst of the storm

  • Isaac leaves flooding, power outages in its path

    Hurricane Isaac lost its Category 1 hurricane status midday Wednesday and was downgraded to a tropical storm, but the severe rains and winds which it brought with it have not let up much; the number of power outages continues to increase as the number of homes and businesses without electricity is now up to 834,000 between Louisiana, Mississippi, Alabama, Florida, Texas, and Arkansas, with over one-third of the outages in Louisiana alone

  • NSF awards Norwich University a grant for computer security scholarships

    Norwich University in Vermont was awarded a $975,000 grant from the National Science Foundation’s (NSF) Scholarship for Service program; the funds will be used to support Information Assurance students; the students will fulfill the “service” obligation through employment by a government agency in their area of information assurance expertise for two years

  • Evaluating fresh water sustainability in the southern U.S.

    Researchers have embarked on 4-year federal research effort to evaluate freshwater sustainability across the southern United States and develop policy recommendations on what can be done to make the best use of water supplies in the face of population growth and the effects of climate change over the next ten to thirty years

  • Hurricane Isaac downgraded from Category 1 hurricane to tropical storm

    Hurricane Isaac was downgraded from a category 1 hurricane to a tropical storm. The storms winds have dropped below 70 mph, but the storm is moving very slowly throughout the gulf area at about 6 mph; at this point officials estimate that Isaac is expected to cause $1.5 billion in insured losses
