• Flood-proofing New York City with storm barriers

    New York City faces two problems with water: rising ocean level and surges created by hurricanes and Nor’easters; engineers propose a system of barriers to prevent New Orleans-like flooding

  • Melting Greenland ice threatens northeast U.S., Canada

    The melting of Greenland’s ice sheets is driving more and more water toward the already threatened coastlines of New York, Boston, Halifax, and other cities in the northeastern United States

  • A fish called WANDA

    Aussie researchers develop a robotic fish that can swim toward objects of interest to investigate; the Wireless Aquatic Navigator for Detection and Analysis (WANDA) is propelled by a flexible joint tail fin that is activated through artificial muscles made from a conducting polymer

  • U.S. unprepared for severe solar storms

    Mankind’s vulnerability to disruptions caused by severe solar storms has increased as a result of the increasing dependence of human societies on technology and electricity; a storm on the scale of the 1859 Carrington Event could damage the U.S. electrical grid to such an extent that vast regions of the country could be without power for weeks, perhaps months.

  • Rules about hazmat trains worry Pennsylvania officials

    Officials in Pennsylvania’s York and Adams counties are uneasy about the prospect of having hazardous material roll through their counties

  • Fly ash as source material for fireproof concrete

    Australia’s coal-fired power plants produce 13.5 million tons of fly ash every year; researchers show that this ash may be used as valuable source material for fireproof concrete;

  • Opposition growing to LNG project near Baltimore

    Virginia-based gas company AES wants to build a liquefied natural gas terminal in eastern Baltimore County; the Federal Energy Regulatory Commission placed 169 conditions, mostly related to safety and environment, on its approval of the project; residents in the neighboring communities say the company is far from meeting these conditions

  • Dounreay nuclear dismantling team to use giant robot

    The U.K.’s experimental fusion nuclear reactor was ordered shut down and dismantled; dismantling team unveils a design for a 75-ton robot which will cut up radioactive equipment

  • Glass-based coating for reinforcement bars for sturdier infrastructure

    Researchers develop glass-based coating for reinforcement bars that helps prevent corrosion and strengthens the bond between steel and concrete; the material could help engineers build stronger bridges and increase the longevity of other steel-reinforced structures

  • SCADA more vulnerable than ever

    Modern SCADA networks are more vulnerable than ever because they use open networking standards (such as TCP/IP), are now deployed under less secure operating systems (Windows), are connected to other networks (including Internet), and cannot be easily updated and rebooted

  • U.S. reassesses safe water levels in New Orleans' outfall canals

    New Orleans has three outfall canals, the role of which is similar to that of a storm drain under a city street; since Katrina, there have been disagreements among engineers as to how much water would it be safe for each of the three canals to handle during a storm

  • Oregon needs to raise Hagg Lake dam for fear of earthquakes

    In Oregon they expect the Big One — a massive earthquake — sometime in the next fifty years; one measure of preparation is to raise the height of dams so that earthquake-generated waves in the reservoirs behind the dams would not spill over and flood the neighboring territory

  • China deploys secure computer operating system

    China has installed a secure operating system known as “Kylin” on government and military computers designed to be impenetrable to U.S. military and intelligence agencies

  • Drinking water monitored by CSIRO-developed sensor network

    Lake Wivenhoe, which spans an area about the size of the city of Brisbane, supplies water to 1.5 million residents in south-east Queensland; CSIRO deploys its FLECK smart wireless sensor network technology to monitor water quality

  • NERC approves strengthened cyber security standards

    The North American Electric Reliability Corp.’s (NERC) independent Board of Trustees last week approved eight revised cyber security standards; entities found in violation of the standards can be fined up to $1 million per day, per violation in the United States
