• California lawmakers work to improve utilities’ disaster preparedness

    California lawmakers are considering a bill to better prepare public utilities for emergencies and disasters following a series of severe storms that left thousands without power across the state

  • Wireless sensors effective in protecting critical infrastructure

    A key to critical infrastructure security is effective monitoring of such infrastructure; a European research project has now successfully demonstrated a wireless sensor-based solution for cost-effective monitoring of electricity distribution networks and water networks

  • Sustaining high-quality groundwater

    Intensive agriculture practices developed during the past century have helped improve food security for many people but have also added to nitrate pollution in surface and ground waters

  • Predators may have contributed to 2007 Wall Street collapse

    A new study retraces events to show that at a critical point in the financial crisis, the stock of Citigroup was attacked by traders by selling borrowed stock (short-selling) which may have caused others to sell in panic; the subsequent price drop enabled the attackers to buy the stock back at a much lower price

  • Fukushima reaches cold shutdown conditions, critics scoff

    Last week Japanese officials declared that the beleaguered Fukushima Daiichi power plant had become stable enough for engineers to complete a “cold shutdown”; officials also stated that the facility had ceased to leak substantial amounts of radiation, a claim received skeptically by critics

  • Innovative device removes heavy metals from water

    Engineers at Brown University have developed a system that cleanly and efficiently removes trace heavy metals from water; in experiments, the researchers showed the system reduced cadmium, copper, and nickel concentrations, returning contaminated water to near or below federally acceptable standards; the technique is scalable and has viable commercial applications, especially in the environmental remediation and metal recovery fields

  • Building earthquake-proof buildings

    Researchers in Australia are leading an international project to help identify buildings most vulnerable to earthquakes and the best ways to strengthen them

  • Scrub carbon dioxide directly from the atmosphere too expensive

    While it is possible chemically to scrub carbon dioxide from Earth’s atmosphere in order to lessen the severity of global warming, the process is prohibitively expensive for now; best to focus on controls for coal-burning power plants, say researchers

  • Improving pothole repairs

    The alarming increase in the number of road potholes in the United Kingdom — an outcome of reduced road maintenance, increasing traffic volumes, heavier loads, and repeated adverse weather — is creating potentially hazardous driving conditions, causing serious concerns to the authorities as well as to the public; engineers are looking foe ways to improve pothole repairs

  • “Smart Connector” to detect, pinpoint damage to cellular cables

    Researchers have developed the Smart Connector, a new sensor that once installed in the connecting units of coaxial cables can provide information about equipment damage and pinpoint the exact location through self-diagnosing technologies — some of the most advanced in the field today

  • The north of England can become the world’s nuclear base

    Despite the repercussions from Fukushima, the nuclear new-construction renaissance continues in countries such as China, India, and the United Kingdom with sixty reactors under construction, 155 planned, and a further 338 proposed’ a new study suggests the that the north of England can become a hub for nuclear power-related activities

  • Study tracks safety of underground CO2 storage

    An international team of geoscientists show that carbon dioxide can safely be stored underground in depleted natural gas fields; fhe experiment, in the Otway basin near Melbourne, Australia, is the most heavily monitored project for CO2 storage in the world

  • Small, modular reactors to figure in U.S. energy future

    A newly released study concludes that small modular reactors (SMR) may hold the key to the future of U.S. nuclear power generation; an SMR would have a generating capacity of 600 megawatts or less, would be factory-built as modular components, and then shipped to their desired location for assembly

  • U.K. approves new reactor designs

    U.K. regulators have given interim approval to two new nuclear reactor designs — the EDF and Areva’s UK EPRTM and Westinghouse’s AP1000; the regulators say that there are still some issues to be addressed, and that neither reactor can be built in the United Kingdom until these issues are resolved

  • Electrical grid needs cybersecurity oversight: study

    In a recently released report, researchers from the Massachusetts Institute of Technology say that a single federal agency should be tasked with protecting the United States’ electrical grid from cyberattacks; the Obama administration has proposed that DHS assume responsibility for the grid, while Congress has submitted proposals for both the Department of Energy and the Federal Energy Regulatory Commission (FERC)
