• States may join feds in regulating infrastructure cybersecurity

    Dealing with cybersecurity issues relating to U.S. inmfrastructure has largely been a federal responsibility, carried out through the North American Electric Reliability Corporation Critical Infrastructure Requirements (NERC-CIP)’ the limitations of these requirements have led state regulators to consider increasing state role in infrastructure protection

  • Rehabilitating historical structures using laser scanning technology

    The Carmel Mission Basilica in California is undergoing a restoration using cutting-edge laser scanning technology; earlier this year, engineers the from Blach Construction Company  teamed up with CyArk, a non-profit foundation that digitally preserves historical sites, to shoot laser beams at and within the basilica to create precise digital maps of the building from different angles

  • U.S. energy policy should emphasize supply security, not energy independence

    America’s policymakers need to consider whether energy independence is really necessary to achieve adequate, reliable and affordable energy supplies, according to a new report from Deloitte; the United States already enjoys significant energy independence for most sectors and much of our economy

  • Water level gauges failed during Hurricane Isaac

    As Hurricane Isaac beat down on New Orleans, the damage it caused was nowhere near as severe as that of Katrina, but it lasted longer than most people expected and for the U.S. Army Corps of Engineers, it provided a field test of a multi-billion dollar investment in flood protection

  • China’s Mekong River dams undermine neighbors’ economies, food production

    Five Chinese dams on the Mekong River’s upper portions have caused rapid changes in water level, and other adverse effects, downstream, especially in Vietnam, Cambodia, Thailand, and Laos, where millions of people rely on the river for water, food, and transportation

  • Carbon dioxide “corrodes” ice, causing glaciers, ice caps to crack

    The amount of carbon dioxide in the atmosphere has risen from roughly 280 ppm shortly before the industrial revolution to about 390 ppm today; now researchers done atom-level simulations that suggest that increased concentrations of the gas causes ice to become more brittle, and so more likely to break up or crack; this explains the cracking of glaciers and ice caps

  • U.S. keeps collecting money for a nuclear waste repository – but has no plans to build one

    Illinois utility customers have paid the U.S government $1.9 billion to store spent nuclear fuel from nuclear plants in the state in a permanent national nuclear waste repository; in the last thirty years, the U.S. government has collected $30 billion from utilities toward this permanent storage, and it keeps collecting $750 million a year; trouble is, in February 2009 the Obama administration decided to “defund” the Yucca Mountain nuclear repository project, and the U.S. government no longer has active plans for a centralized nuclear waste storage facility

  • Y-12 Nuclear Complex’s uranium processing facility to be redesigned

    Weeks after the inadequacy of security measures at the Y-12 Nuclear Complex came to light — an 82-year old nun and her two senior citizen colleagues eluded the facility’s fences and security to spend a few hours on the site’s grounds and spray-paint anti-nuclear slogans on its walls – criticism is directed at the design shortcomings of a new uranium processing facility; among other things, the roof of the new facility will have to be raised by thirteen feet because the designers did not take into account the size of the equipment the new facility will house 

  • Study maps greenhouse gas emissions down to building, street level for U.S. cities

    Researchers have developed a new software system capable of estimating greenhouse gas emissions across entire urban landscapes, all the way down to roads and individual buildings. Until now, scientists quantified carbon dioxide (CO2) emissions at a much broader level

  • Congressional panel says two Chinese telecom companies pose “national security threat” to U.S.

    A report by the House Intelligence Committee recommended that the U.S. government be barred from doing business with two Chinese telecommunications firms – Huawei and ZTE – and that American companies should avoid buying their equipment; a committee report said the two companies pose a threat to U.S. national security; installing these companies’ technology in U.S. communication network will not only allow these companies, acting on behalf of the Chinese military and intelligence, to steal sensitive national security information and trade secrets of private U.S. companies – it will also allow China to attack and paralyze large portions of U.S. critical infrastructure

  • NRC sees no evidence of bad security practices at Michigan nuclear plant

    The Nuclear Regulatory Committee (NRC) released  information last week about a leak earlier this summer at the Palisades plant near South Haven, Michigan; the plant has been mired in controversy this year, as at least three water leaks have occurred in the past several months, and the plant has one of the worst safety ratings in the United States

  • Environmentalists concerned about earthquakes tests near California nuclear plant

    The Pacific Gas and Electric Company (PG&E) wants to use air guns to emit strong sound waves into a large near-shore area which includes parts of marine reserves; the purpose: creating three dimensional maps of fault zones near its Diablo Canyon nuclear plant in California; the plans have federal and state officials concerned about marine life and public safety

  • Dallas area earthquakes were caused by fracking: geophysicists

    Three earthquakes that hit a Dallas suburb last week could be connected to fracking operations, according to a local geophysicist who studies earthquakes in the region; the earthquakes were considered minor, with the biggest one registered at a 3.4 on the Richter scale; no injuries were reported despite many emergency calls

  • Infrastructure security market to reach a value of $32.55 billion in 2012

    The infrastructure security market has rapidly developed over the past decade, with the formation of a host of governmental and international organizations dedicated to homeland security and critical infrastructure protection; a new report says growth trends in the infrastructure protection market will continue

  • CO2 emissions as a result of economic growth, decline not symmetrical

    Estimating the trajectory of CO2 emissions, an important part of planning for climate change mitigation and adaptation, depends in part on understanding how these emissions are influenced by the economy; new study finds that in years when GDP per capita shrinks, CO2 emissions per capita do not decline in equal proportion to the amount by which they increase with economic growth
