• TVA considering raising height of dams to prevent future floods

    The dams located on the upper Tennessee River never had flood waters top them, and government officials want to keep it that way, saying that due to recent disasters such as the 2010 Nashville flood and the 2011Fukushima tsunami, they need to prepare the worst possible situation

  • Removing sea defenses may reduce impact of coastal flooding

    Coastal defenses put in place over the last century or so have re-shaped the U.K. coastline, artificially protecting some areas, but at the expense of beaches in adjacent areas; this man-made situation increases the risk of flooding in low lying coastal settlements where beaches act as a natural flood defense; beach levels can be artificially recharged, but maintaining this indefinitely along large stretches of coastline is costly and likely to be unsustainable

  • Pulverized rocks used to strip CO2 from emissions of steel, coal, cement plants

    Researchers in Quebec are developing a process which would see steel, coal, and cement plants as well as oil and gas facilities remove most of the carbon dioxide (CO2) from their emissions through chemical reactions with various types of crushed rocks in the stacks

  • Huawei rejects U.S. “threat to national security” claims

    In October the United States House Intelligence Committee issued a report warning U.S. companies against using two Chinese companies, Huawei and ZTE, for their telecommunication technology needs; the report said that the firms may be too close to China’s Communist Party and its military’ the report also suggested their products and services could pose a threat to the security of the United .States; Huawei vigorously disputes both claims

  • Nuclear wonder fuel poses serious weapons proliferation risk

    Thorium is being touted as an ideal fuel for a new generation of nuclear power plants, but new study shows that it may pose a serious weapons proliferation risk; experiments to separate protactinium-233 show that it is feasible that just 1.6 tons of thorium metal would be enough to produce eight kilograms of uranium-233, which is the minimum amount required for a nuclear weapon; a nuclear reactor using thorium for fuel could produce that amount of thorium metal in less than a year

  • Critics: post-Fukushima nuclear power may be safer, but it is still not cost effective

    The Southern Company wants to show its customers that it has learned from the Fukushima disaster in Japan and has protected its nuclear reactors to make sure the same thing does not happen in the United .States’ critics of nuclear power are not convinced – and also, they say, alternative energy sources, such as natural gas, are much cheaper to produce

  • Quantum cryptography may soon go main stream

    Researchers have perfected a technique that offers a less expensive way to ensure the security of high-speed fiber-optic cables, protecting communication networks from unauthorized snooping; this means that existing telecom networks can now be secured with this ultimate form of encryption

  • Andrew Cuomo heads to Washington to push for disaster aid

    Governor Andrew Cuomo says that New York needs $33 billion to cover storm cleanup and another $9 billion for new programs to protect against future storms; Governor Chris Christie of New Jersey says his state will need $36.8 billion to recover from Sandy; it is not clear how Congress and the administration, locked in a tug of war over differing deficit cut plans, will respond

  • Tunnel disaster shows age of Japan’s infrastructure, but there is no money to fix it

    The collapse of hundreds of concrete ceiling slabs in a tunnel just outside Tokyo has focused the attention of the Japanese on the country’s  has citizens calling for Japan to fix its aging infrastructure; the amounts of money needed for this refurbishing are large, and , but signs indicate that Japan may not have the money, as the public debt is already more than 200 percent of its Gross Domestic Product (GDP)

  • Life of U.K. nuclear power plants extended

    U.K. operator EDF Energy has announced it will extend the expected operating life of two of its nuclear power stations by seven years; Hinkley Point B and Hunterston B power stations are now expected to remain operational until at least 2023, generating enough electricity for around two million homes; the decision follows the five year extensions to Heysham 1 and Hartlepool announced in 2010 and come after extensive reviews of the plants’ safety cases and continuing work with the independent nuclear regulator

  • Marines looking for solar energy in combat outposts

    The Office of Naval Research (ONR) is looking to the sun for energy in an effort to help Marines do away with diesel-guzzling generators now used in combat outposts; the Renewable Sustainable Expeditionary Power (RSEP) program seeks to create a transportable renewable hybrid system that can provide Marines with electricity for a 15-day mission without relying on fuel resupply convoys that often become targets for adversaries

  • Responding to future oil spills: lessons learned from Deepwater Horizon

    A special collection of articles about the Deepwater Horizon oil spill provides the first comprehensive analysis and synthesis of the science used in the unprecedented response effort by the government, academia, and industry;with the benefit of hindsight and additional analyses, these papers evaluate the accuracy of the information that was used in real-time to inform the response team and the public

  • Fracking in Michigan

    In hydraulic fracturing, large amounts of water, sand and chemicals are injected deep underground to break apart rock and free trapped natural gas; though the process has been used for decades, recent technical advances have helped unlock vast stores of previously inaccessible natural gas, resulting in a fracking boom; researchers are examining the benefits of fracking for Michigan

  • Lloyd’s says countries are under insured against natural disasters

    Lloyd’s of London, the world’s largest insurance company, has warned seventeen countries that a $165 billion global insurance deficit leaves them vulnerable to long-term natural disaster costs; Lloyds says the world may not be able to afford another year like 2011, when natural disasters such as the earthquake and tsunami in Japan and the floods in Thailand caused $4.6 trillion dollars of damage to infrastructure, homes, and businesses, and which resulted in the largest disaster claims ever

  • Hard choices to be made on adapting infrastructure to climate change

    The costs of adapting to climate change, sea-level, and flooding include the upfront expenses of upgrading infrastructure, installing early-warning systems, and effective organizations, as well as the costs of reducing risk, such as not building on flood plains
