• Researchers develop record-breaking plastic solar cell

    Researchers at the University of California, Los Angeles (UCLA) have made a breakthrough with plastic solar cells, creating a record-breaking polymer cell that converts 10.6 percent of the sun’s energy into electricity

  • New report paints dire picture of Japanese Fukushima response

    A new report reveals that last year’s nuclear crisis at Japan’s Fukushima Daiichi atomic energy plant was dangerously close to spiraling out of control as senior officials bickered internally, lacked critical information on the extent of the damage, and covertly considered the possibility of evacuating Tokyo

  • Robots to climb and assemble structures, making construction safer

    In the near future, armies of robots could nimbly be crawling up towers and skyscrapers to make repairs, so humans do not have to; the design of the truss pieces, which have ridges and specially designed locks so the robot can manipulate them, is as important as the robot itself, and researchers express the hopes that in the future such robot-friendly building components would be standardized for widespread use

  • Physicists predict when brittle materials fail

    It does not happen often, but structures like bridges, airplanes, and buildings do fail, sometimes catastrophically; what are the odds, and how can it be prevented? Researchers just published new theoretical insights into the probability of structural failures, based on hundreds of thousands of computer simulations

  • Smart outlet to bring flexibility, resiliency to smart grid architecture

    Researchers developed an experimental “smart outlet” that autonomously measures, monitors, and controls electrical loads with no connection to a centralized computer or system; the goal of the smart outlet and similar innovations is to make the power grid more distributed and intelligent, capable of reconfiguring itself as conditions change

  • Cheaper natural gas leads to reduced U.S. carbon emissions

    In the United States, lower emission from power plants in 2009 was driven by competitive pricing of natural gas versus coal; Harvard University researchers develop a model which identifies the relationship between the cost of electricity generation from coal and gas and the fraction of electricity generated from coal

  • Future aircraft could capture, re-use some of their own power

    When an Airbus 320 lands, a combination of its weight and speed gives it around three megawatts peak available power; researchers work on making the aircraft of tomorrow contribute to their power needs by harnessing energy from the wheel rotation of their landing gear to generate electricity

  • Nuclear accident reawakens California’s anti-nuke movement

    Following the discovery of a small leak at a nuclear power plant near San Diego, California in January, the state’s anti-nuclear movement has hit a fever pitch

  • U.S. water shortages loom

    More than 1 in 3 counties in the United States could face a “high” or “extreme” risk of water shortages due to climate change by the middle of the twenty-first century; 7 in 10 of the more than 3,100 U.S. counties could face “some” risk of shortages of fresh water for drinking, farming, and other uses

  • NRC approves first new nuke reactors since 1978

    For the first time since 1978, U.S. nuclear regulators have approved the construction of a new nuclear power plant; the Nuclear Regulatory Commission (NRC) recently voted four-to-one in favor of granting Southern Co. a license to build two additional reactors at its Plant Vogtle nuclear facility near Augusta, Georgia

  • New source of power: bugs from space

    Researchers find that bacteria normally found thirty kilometers above the earth are highly efficient generators of electricity

  • Recycled glass in cement makes concrete stronger

    Researchers have found that by mixing ground waste glass into the cement that is used to make concrete, the concrete is stronger, more durable, and more resistant to water; in addition, the use of glass helps reduce the amount of glass that ends up in landfills

  • Helping software to help improve software

    The earlier a problem is detected, the easier it can be solved; before implementing complex programs in a time-consuming process, computer scientists also want to know whether they will reach the desired performance

  • Proposed EPA budget cuts funding from clean air and water grants

    President Obama’s latest proposed budget for fiscal year 2013 cuts $105 million from the Environmental Protection Agency’s (EPA) budget, primarily from funds aimed at treating wastewater and drinking water

  • A nano method to clean polluted water

    Decontaminating polluted waste water costs millions, but a new discovery by scientists at the University of Brighton could result in huge savings as well as delivering safer, cleaner water
