• Aerospace materials for on-site building of pipes of infinite length

    Concrete and steel pipes are built in short sections to fit on standard 18-wheel trucks; the heavy industrial manufacturing processes, long-distance trucking, and leak-prone joints used in steel and concrete pipe construction exact a heavy toll on the environment, not to mention bottom line; the solution: a new pipe design, consisting of a central layer of lightweight plastic honeycomb, which can be built onsite as a single section of virtually infinite length

  • Greenland melting breaks record four weeks early – with two weeks more to go

    Melting over the Greenland ice sheet shattered the seasonal record on 8 August — a full four weeks before the close of the melting season; with more melting yet to come in August, this year’s overall melting will fall way above the old records; researchers devise a “cumulative melting index,” which measures the type of melting which adds to the runoff of melt-water that makes sea levels rise

  • Toilet Challenge, 1: Caltech’s solar-powered toilet wins Reinvent Toilet Challenge

    The World Health Organization reports that 2.5 billion people around the globe are without access to sanitary toilets, which results in the spread of deadly diseases; every year, 1.5 million people, mostly those under the age of five, die from diarrhea; Caltech scientist awarded grant to develop solar-powered sanitation system

  • Toilet Challenge, 2: Loughborough’s hydrocarbonization design wins second Reinvent the Toilet Challenge prize

    Researchers from Loughborough University, located in Leicestershire, United Kingdom , won second prize in the Reinvent the Toilet Challenge; their toilet uses a process called Continuous Thermal Hydrocarbonization which kills all pathogens to create safe to handle, valuable material and uses power from heat generated during processing

  • Toilet Challenge, 3: U Toronto wins toilet challenge third place for sand filter and UV-ray design

    The U of T solution is novel in its simplicity. It uses a sand filter and UV-ray disinfecting chamber to process liquid waste and a smolder chamber, similar to a charcoal barbeque, to incinerate solid waste that has been flattened and dried in a roller/belt assembly

  • DHS seeks better ways to detect ultra light aircrafts used by smugglers

    As the war on drugs continues with every sunrise and sunset, DHS has awarded a contract just short of $100 million for a specialized system which will be able to detect ultralight aircrafts which are used to smuggle drugs across the border

  • Lifelike, cost-effective robotic hand disables IEDs

    Researchers at Sandia National Laboratories have developed a cost-effective robotic hand that can be used in disarming improvised explosive devices, or IEDs; the Sandia Hand addresses challenges which have prevented widespread adoption of other robotic hands, such as cost, durability, dexterity, and modularity

  • Unmanned sub-tracker to address a silent threat

    The growing number of adversaries able to build and operate quiet diesel electric submarines is a national security threat that affects U.S. and friendly naval operations around the world; DARPA autonomous surface vessel will track and follow enemy subs for months

  • Soft robots for search-and-rescue and reconnaissance missions

    Soft robots are useful because they are resilient and can maneuver through very constrained spaces, which makes them useful for search-and-rescue and reconnaissance missions; researchers show a soft robot made of silicone; it can walk, change color, and light up in the dark; it can even change temperature; it can do all of this for less than $100

  • New earthquake assessment finds increased risk for Washington Dams

    Central Washington state has always been considered low risk for earthquakes back when big hydropower dams went up on the Columbia River many decades ago; a recently completed seismic hazard assessment, however, shows that there is a much greater earthquake potential for the area than previously thought; now, dam owners have to figure out whether their dams can hold up to an earthquake; if retrofits are needed, they could cost hundreds of millions of dollars

  • U.S. wind power market riding a wave which is likely to crest in 2012

    Facing looming policy uncertainty beyond 2012, the United States remained one of the fastest-growing wind power markets in the world in 2011 — second only to China; the expiration of key federal incentives could bring that wave crashing down in 2013, , despite a significant decline in the cost of wind energy

  • U.S. Army trains rats in explosives detection

    Landmines kill between 15,000 and 20,000 people a year, and continue to kill adults and children decades after a conflict ends; the U.S. Department of Defense currently relies on dogs as the animal of choice for explosives detection, but Pentagon researchers want to see whether rats can be trained to do the job; rats are smaller so they can search smaller spaces than a dog can, and are easier to transport

  • New system could predict solar flares, give advance warning to help protect power grids

    Researchers may have discovered a new method to predict solar flares more than a day before they occur, providing advance warning to help protect satellites, power grids, and astronauts from potentially dangerous radiation

  • Close to 1,000 earthquakes shook Arizona in 3-year period: study

    Historically, most of Arizona has experienced low levels of recorded seismicity, with infrequent moderate and large earthquakes in the state; comprehensive analyses of seismicity within Arizona have not been previously possible due to a lack of seismic stations in most regions, contributing to the perception that widespread earthquakes in Arizona are rare; a new study debunks this myth

  • Future increases in U.S. natural gas exports may not be as large as thought

    Amid policy debate over potential liquefied natural gas (LNG) exports from the United States, a new study predicts the long-term volume of exports from the United States will not likely be very large; the paper also argues that the impact on U.S. domestic natural gas prices will not be large if exports are allowed by the U.S government
