• Louisiana levee to use stabilizing fabric

    The 1,600-foot earthen levee, which runs south from the Old Estelle Pump Station, has failed twice, once in the early 1990s and again in 2007 when two sections totaling 600 feet long slumped badly; Army Corps of Engineers will use geotextile fabric to stabilize known trouble spots before raising the levee from 10 feet to 14.5 feet

  • The brief

    Smart grid technologies may themselves introduce new problems, such as increasing the vulnerability to cyber attack, as power grid resources become increasingly linked to the Internet

  • DHS to boost cybersecurity spending in 2010

    Of the $43 billion DHS 2010 budget, about $397 million is aimed at addressing cybersecurity issues; the amount is $84 million, or about 27 percent, higher than the $313 million that was allocated for information security spending in 2009

  • Vulnerability identified in Amazon's cloud computing

    Researchers show that it is possible to find would-be victims within cloud hardware; cloud technologies use virtual machines — remote versions of traditional onsite computer systems; the number of these virtual machines can be expanded or contracted on the fly to meet demand, creating tremendous efficiencies — but the actual computing is performed within one or more physical data centers, creating troubling vulnerabilities

  • How credible -- and serious -- is the cyber threat the U.S. faces?

    New report examines recent cyber attacks on South Korea and asks whether whether the attacks constituted an act of war and whether they could have been the work of a terrorist group; the answer is no on both counts; the U.S. dependence on digital technology makes it somewhat more vulnerable to cyber attacks than other nations,

  • The brief

    General IT spending by the U.S. government will increase by 3.5 percent a year between 2009 and 2014; during the same time, U.S. government spending on cybersecurity will grow at a compound rate of 8.1 percent a year, and spending on vendor-supplied information security products and services will increase from $7.9 billion in 2009 to $11.7 billion

  • Despite concerns, development still heads to the coast

    Many scientists predict that by 2100, sea levels would rise more than one meter; still, Florida has opened more vulnerable areas along the Atlantic coast to construction — and has done so more than any other state

  • Aussies worry about rising sea levels

    About 80 percent of Australians live in coastal areas, and a new parliamentary report recommends new laws banning further development in coastal regions

  • New material makes buildings more fire resistant

    New material, called “liquid granite,” is fire resistant to temperatures in excess of 1,100oC; it reduces the fire risk in buildings because, unlike concrete, it does not explode at high temperatures

  • Raytheon buys BBN for $350 million

    The latest example of traditional defense contractors expanding into the information systems sector is Raytheon’s acquisition of Massachusetts-based BBN, the company which put the “@” in e-mail addresses

  • Obama announces $3.4 billion investment in smart grid

    President Barack Obama today announced the largest single energy grid modernization investment in U.S. history, funding a broad range of technologies that will spur the U.S. transition to the smart grid; applicants say investments will create tens of thousands of jobs

  • NSA to build $1.5 billion cybersecurity center near Salt Lake City

    Facility will support Comprehensive National Cybersecurity Initiative; one goal of the new center will be to help federal agencies reduce government exposure to Internet-based threats by reducing and consolidating the number of external Internet connections across government

  • Tech projects to receive big chunk of second wave of stimulus spending

    Information technology projects will receive significant funds, implementation director says;

  • Tensions simmer between India and Bangla Desh over dwindling water sources

    The ice and snow caps of the Himalayas are depleted by global warming; as the availability of water in Himalayan-fed river systems that support 1.3 billion people drops, experts expect the border between India and Bangladesh to be the first flashpoint of an intensifying battle across south Asia
