• Operator of Hanford nuclear disposal site fires scientists who voice safety concerns

    The Hanford project in Washington State is the Department of Energy’s (DoE) largest nuclear cleanup project. DoE plans to transform fifty-six million gallons of radioactive sludge, currently stored in underground tanks, into solid glass. Scientists and engineers who work at Hanford have questioned the effectiveness of the required technology, and have voiced serious concerns about safety issues. Two of those who were the most persistent in voicing their concerns about safety have been fired, and a third one has left his job voluntarily.

  • Unsupervised robotic construction crew to build flood defenses

    See video

    On the plains of Namibia, millions of tiny termites are building a mound of soil — an 8-foot-tall “lung” for their underground nest. They do so without a supervisor, foreman, or CEO to tell them what to do. During a year of construction, many termites will live and die, wind and rain will erode the structure, and yet the colony’s life-sustaining project will continue. Harvard researchers, inspired by the termites’ resilience and collective intelligence, have created an autonomous robotic construction crew. The system needs no supervisor, no eye in the sky, and no communication: just simple robots — any number of robots — that cooperate by modifying their environment. In the future, similar robots could lay sandbags in advance of a flood, or perform simple construction tasks on Mars.

  • Large offshore wind farms could weaken hurricanes before they make landfall

    Computer simulations have shown that offshore wind farms with thousands of wind turbines could have sapped the power of three real-life hurricanes, significantly decreasing their winds and accompanying storm surge, and possibly preventing billions of dollars in damages. For example, an array of 78,000 wind turbines off the coast of New Orleans would have significantly weakened Hurricane Katrina well before it made landfall, reducing wind speeds between 80 and 98 mph, and decreasing the storm surge by up to 79 percent.

  • Advancing algae’s viability as a biofuel

    Lab success does not always translate to real-world success. A team of scientists, however, has invented a new technology that increases the odds of helping algae-based biofuels cross that gap and come closer to reality. The current issue of Algal Research showcases the team’s invention — the environmental photobioreactor. The ePBR system is the world’s first standard algae growing platform, one that simulates dynamic natural environments.

  • Protecting the grid from geomagnetic storms

    A geomagnetic storm disrupts the Earth’s magnetic field by producing geomagnetically induced currents (GICs) on the Earth’s surface, which can enter the power grid at transformer stations and move along power lines, disrupting normal operations. A geomagnetic storm would reach Earth between fourteen and ninety-six hours, leaving little time to safeguard critical infrastructure. U.S. regulators are drafting reliability standards and procedures to protect the U.S. power grid from such storms.

  • Limitations and side effects of large-scale geoengineering

    Despite international agreements on climate protection and political declarations of intent, global greenhouse gas emissions have not decreased, and with the accelerating industrialization of emerging markets, are not likely to any time soon. Therefore, large-scale methods – called geoengineering or climate engineering — artificially to slow down global warming are increasingly being discussed. Scientists say that the long-term consequences and side effects of these methods have not been adequately studied.

  • Testing vibration caused by high-speed trains

    New high-speed train lines are likely to be built as cities grow, and one problem planners have foreseen is vibrations in the ground caused by trains passing at speed. While these vibrations would probably be too small to damage buildings, they could disrupt the work of buildings such as a hospital by affecting sensitive equipment. Scientists have developed a new model to predict how much a new high-speed railway would shake the ground around it, and the effect this could have on those living near the line.

  • Damage to coastal infrastructure from storm surges, floods may reach 9% of global GDP

    Damage to the world’s coastal infrastructure as a result of flooding, sea level rise, and coastline development is expected to cost as much as 9 percent of global Gross Domestic Product (GDP) according to a new report published in the Proceedings of the National Academy of Sciences(PNAS).

  • Not much is known about long-term health effects of chemical leaked in W.Va.

    In January, 10,000 gallons an obscure chemical called 4-methylcyclohexanemethanol, or MCHM, used in processing coal, leaked from storage tanks into the nearby Elk River in the Charleston, West Virginia area, contaminating the water of more than 300,000 residents for days. To what degree MCHM affects long-term human and fetal health is a major concern for residents because of the lack of complete toxicology and other studies on the chemical.

  • U.K. could generate half its energy needs from currently underutilized bioenergy sources

    The United Kingdom could generate almost half its energy needs from biomass sources, including household waste, agricultural residues, and home-grown biofuels by 2050, new research suggests. Scientists found that the United Kingdom could produce up to 44 percent of its energy by these means without the need to import. The new study highlighted the U.K. potential abundance of biomass resources that are currently underutilized and totally overlooked by the bioenergy sector.

  • 50-state roadmap to renewable energy unveiled

    Researchers recently developed detailed plans to transform the energy infrastructure of New York, California, and Washington states from fossil fuels to 100 percent renewable resources by 2050. The new roadmap to renewable energy for all fifty states was presented on 15 February at the annual meeting of the American Association for the Advancement of Science (AAAS) in Chicago. The online interactive roadmap is tailored to maximize the resource potential of each state.

  • Iran-Russia oil deal threatens nuclear negotiations

    Iran said that in exchange for Iranian oil, Russia could build a second reactor at Iran’s Bushehr nuclear power plant. Russia could also provide Iran with trucks, railroad tracks, mini-refineries, grain, and other goods for Iranian oil. In a deal worth $1.5 billion a month, Iran would export 500,000 barrels of oil per day to Russia. The deal would increase Iran’s oil exports, which have been reduced to about one million barrels a day by American and European sanctions aimed at curbing Iran’s nuclear program.

  • Out-of-control giant satellite poses “Gravity”-style space debris threat

    Envisat, a £1.8 billion, 9-meter-long behemoth, was launched by the European Space Agency (ESA) in 2002, and used ten sophisticated sensors to observe and monitor Earth’s land, atmosphere, oceans and ice caps. ESA, however, lost contact with the satellite in April 2012 — and declared the end of the mission soon after. The satellite now orbits the Earth free from human control at an altitude of 790 km — where the amount of space debris around the planet is greatest. In a paper, University of Leicester students point out that unless it is brought under control, Envisat could potentially pose a threat similar to the events which plague Sandra Bullock in the Oscar-nominated sci-fi thriller “Gravity.”

  • Skeptics doubt voluntary Cybersecurity Framework will achieve its goal

    The Framework for Improving Critical Infrastructure Cybersecurity, developedby NIST following Executive Order 13636to promote cybersecurity, has been received with both support and skepticism from critical infrastructure industries. The 41-page document, put together by industry and government experts, offers guidelines on cybersecurity standards and best practices to critical infrastructure firms. It says its role is to be a complement to industries’ existing risk management practices.Skepticssay that without incentives, legislation, or enforcement, the guidelines will not be adopted.”The marketplace will punish any company that implements anything that could be considered excessive security, because it will increase their costs,” says an industry insider.

  • Y-12 protestors receive lengthy prison terms from judge

    Judge Amul R. Thapar sentenced three peace protestors who breached the Y-12 Nuclear Security Complex at Y-12 National Security Complexat Oak Ridge, Tennessee, to lengthy sentences in federal prison. Judge Thapar stated that he did not believe the three defendants — Sister Megan Rice, 84. Michael R. Walli, 65, and Greg Boertje-Obed, 59 — were terrorists but, nevertheless, they had broken the law and must serve sentences which demonstrated that the law should be taken seriously.To reach the Highly Enriched Uranium Materials Facility (HEUMF) building at Y-12, the three peace activists, led by the octogenarian Sister Rice, cut through four fences and escaped detection by security guards authorized to use lethal force, and by ground sensors, sophisticated surveillance cameras, and other security equipment described by Y-12 as “…the most stringent security system in the world.”
