• DHS official: Stuxnet a "game changer"

    The head of the Cybersecurity Center at DHS said Stuxnet is an incredibly large, complex threat with capabilities never seen before; “This code can automatically enter a system, steal the formula for the product you are manufacturing, alter the ingredients being mixed in your product, and indicate to the operator and your anti-virus software that everything is functioning as expected,” he said

  • Minneapolis bridge collapse spawning new bridge research

    Oregon State University developed a new system to analyze the connections that hold major bridge members together; the work also brings focus to a little-understood aspect of bridge safety — that most failures are caused by connections, not the girders and beams they connect, as many people had assumed. The issues involved are a concern with thousands of bridges worth trillions of dollars in many nations

  • Bacteria knit together cracked concrete

    Students at Newcastle University genetically modified a microbe, programming it to swim down fine cracks in the concrete; once at the bottom, it produces a mixture of calcium carbonate and a bacterial glue which combine with the filamentous bacterial cells to “knit” the building back together

  • Purdue engineers test effects of fire on steel structures

    Building fires may reach temperatures of 1,000 degrees Celsius, or more than 1,800 degrees Fahrenheit; at that temperature, exposed steel would take about twenty-five minutes to lose about 60 percent of its strength and stiffness; Purdue researchers experiment with ways to make steel more fire-resistant

  • The U.S. rare-Earth industry can rebound -- over time

    Rare-Earth elements are not that rare; the U.S. has plenty of the metals that are critical to many green-energy technologies, but engineering and R&D expertise have moved overseas; responding to China’s near monopoly, companies in the United States and Australia are ramping up production at two rich sites for rare earths, but the process will take years

  • GWU earthquake simulator helps engineering prepare for the real thing

    George Washington University laboratory’s “shake table” — a $1 million, 10-by-10-foot metal structure that moves in six directions — replicates earthquakes and allows engineering students to test construction materials to see how they hold up under tremors of varying strength

  • New Orleans levee committee uneasy with Corps of Engineers modeling

    The Army Corps of Engineers uses complex computer models for hazard analysis calculations on which billions of dollars worth of repairs and improvements to the federal hurricane levee system are being based; the members of the regional levee commission want their own expert to scrutinize these computer models

  • Research to help reduce coastal flooding

    According to the Environment Agency’s Flooding in England Report, one in six homes in the United Kingdom are at risk from flooding, and 2.4 million properties are vulnerable to coastal/river floods; coastal areas could be saved from the misery of flooding thanks to new research from the University of Plymouth

  • Mini UAVs for infrastructure facilities protection

    Those in charge of critical infrastructure protection are showing increasing interest in using mini UAVs as a tool that will positively identify and “incriminate” threats before deadly force is used to stop them; the requirement is for a mini UAV that can be launched seconds after a threat is initially detected and that has the capability to loiter over the area where the threat was first detected by one of the ground sensors

  • Cyber attack could paralyze air traffic

    This summer we saw the release of the world’s first cyber superweapon, which was said to be targeting Iran’s nuclear facilities as well as infrastructure systems in China; the Stuxnet worm could break into computers that control machinery at the heart of industry, allowing an attacker to assume control of critical systems like pumps, motors, alarms and valves; a similar cyber weapon could allow an attacker to take down air-control systems

  • Australia's AG rules out SCADA security regulations

    Best practice and risk management frameworks not enough, say Aussie SCADA security managers; a scathing 56-page report from the Victoria Auditor General stated that most critical infrastructure operators did not have fully compliant risk management frameworks; still, Australia’s Federal Attorney-General’s Department has ruled out regulation of security standards for supervisory control and data acquisition (SCADA) systems for critical infrastructure, despite a mounting threat landscape

  • Protecting the grid from solar storm-induced blackouts

    Since the beginning of the Space Age the total length of high-voltage power lines crisscrossing North America has increased nearly ten fold; this has turned power grids into giant antennas for solar storm-induced currents; with demand for power growing even faster than the grids themselves, modern networks are sprawling, interconnected, and stressed to the limit — a recipe for trouble

  • BATS: Extending broadband communication, I

    BATS system’s tight integration with the radios, along with the performance characteristics of the directional antenna, are used by BATS’ innovative software to create search patterns and predictive algorithms that automatically locate a desired connection point, establish communications, and track whether one or both of the wireless broadband radios are moving

  • Unease grows as Chinese telecom behemoth gains foothold in U.S.

    China’s Huawei Technologies — a company linked to the People’s Liberation Army, and which has been repeatedly accused of stealing software designs and infringing on patents — is now the world’s second-largest telecom equipment supplier behind Ericsson of Sweden, and with Chinese government backing, it has sewn up major deals in Asia, Africa, and Latin America; a $3 billion in advanced wireless equipment deal with Sprint Nextel will give entry into the U.S. communication market — and this has lawmakers and security experts worried

  • Metal thefts threaten U.K. infrastructure

    The last two years have seen the price of refined copper more than double; at the end of 2008 it was selling it at a low of less than £2,000 a ton, but by earlier this month it had reached more than £5,000; one result is the epidemic of metal theft in the United Kingdom; there have been more than 5,000 such thefts from the railways and the gas and electricity networks this year; and the police says this theft campaign now threatens U.K. infrastructure
