• Keeping water clean

    Cardiff University researchers create a real-time broadband monitor to detect and warn of impurities in water supplies; the new monitor works by using bioluminescence to detect the presence of potentially toxic substances of chemical or biological origin and immediately warn of suspicious change

  • Oil tankers and refineries on high alert based on latest al Qaeda intelligence

    Refineries and ship operators are on a state of heightened alert after documents recovered from the raid on Osama bin Laden’s compound revealed that al Qaeda had considered bombing oil tankers; DHS officials issued the warning to law enforcement officials nationwide based on evidence that al Qaeda operatives had discussed holding drills to practice hijacking and bombing oil tankers to create “an extreme economic crisis” in the United States; port officials and refineries in Houston, Texas are particularly wary, as it is the largest oil producing region in the United States with tankers constantly moving in and out

  • Risk of wetland habitat loss in southern United States

    Between 1992 and 1997, more than 500,000 acres of wetlands were lost in the United States; 75 percent of those losses were attributed to development or agriculture; the greatest loss during this period occurred in the southern United States, with development as the main reason for wetland habitat loss; wetlands are important not only as a habitat for wild life, but as a line of defense against catastrophic floods and intense storms

  • Saudi Arabia seeks $330 million worth of night vision gear

    Saudi Arabia is looking to buy $330 million worth of night vision and thermal vision equipment from the United States; the U.S. government agency facilitating the deal says the proposed sale would bolster Saudi Arabia’s capability to meet current and future threats from potential adversaries during operations conducted at night and during low-visibility conditions

  • More American civil engineers deployed to Japan to study damage

    Last week the American Society of Civil Engineers (ASCE) deployed two more disaster assessment teams to Japan to study the damage wrought by the 11 March earthquake and tsunami; the two teams, the third and fourth deployed by ASCE, will tour the damaged areas which include the approximately 292 square miles inundated by the tsunami; one team will focus on examining the effects that the tsunami and earthquake had on port structures; the other team will focus their efforts on investigating the impact of the earthquake and tsunami on coastal structures like tsunami walls, breakwaters, and seawalls

  • U.K. lab helps company improve its infrastructure monitoring sensors

    London-based Senceive produces sensors used in long-term infrastructure monitoring; the company’s meshed systems of wireless sensors are used to assess the condition of railway structures, track, bridges, culturally significant buildings, and even historical artifacts; the company needed the help of the U.K. National Physical Laboratory to improve the tilt sensing system it manufactures, and verify its accuracy, precision, and limits

  • Historic, desperate measures to control Mississippi River

    The historic levels of water swelling the Mississippi River required the Army Corps of Engineers to take historic measures to prevent catastrophic flooding of Baton Rough and News Orleans: first, the Morganza control structure, located 186 miles upriver of New Orleans and completed in 1954 as part of the Army Corps of Engineers’ broad flood-protection upgrades in the wake of the Great Flood of 1927, was opened for only the second time to allow water to flow out of the river and into the Atchafalaya basin, a designated flood relief area; the Corps says that Saturday marked the first time in history that all three floodways built by corps after 1927 flood — the Morganza Floodway, the Bonnet Carre Spillway, and the Birds Point floodway in Missouri — have been in operation at the same time; about 25,000 people and 11,000 structures are in harm’s way, as up to 25 feet of flooding is expected in a 3,000 square-mile area of Louisiana

  • How safe are U.S. railroads?

    Following the revelation that al Qaeda had aspired to attack U.S. railways, security experts, the media, and lawmakers have turned their attention to improving security for American trains; in a recent interview with CNN, Brian Michael Jenkins, the director of the Mineta Transportation Institute’s (MTI) National Transportation Security Center of Excellence, discussed the current state of railway security, how realistic creating an airline style screening system for railroads would be, and what measures need to be taken to secure railroads; to realistically improve rail security in a cost effective manner, Jenkins urged passengers to begin taking a more active role; Jenkins also urged the United States “to be more realistic about risk”

  • Rebuilding Seattle's viaduct will not result in nightmare commutes

    Debate about how to replace Seattle’s deteriorating waterfront highway has centered on uncertainties in the project’s price tag; drilling a deep-bore tunnel and building an underground highway is estimated to cost around $4 billion, but some worry the final price could be higher, as it was for Boston’s infamous Big Dig; University of Washington statisticians have, for the first time, explored a different subject of uncertainty, namely: how much commuters might benefit from the project

  • Informed response to threat of asteroid collision

    Surveys using ground and space-based telescopes, such as the NASA Spaceguard, have identified many Near Earth Objects (NEOs) that pass close to the Earth, including the 400 meter asteroid 2005 YU55 which will approach to within 325,000 km of the Earth in November this year; early detection of NEOs, and determination which of them is more threatening to Earth, are essential for decisionmakers; Southampton University researchers developed a new software system that could support decisions on how to respond to potential NEO impacts on Earth

  • Turkey plans two earthquake resistant cities to move residents from vulnerable Istanbul

    To encourage residents to move away from seismically unsafe neighborhoods, Turkey’s government recently announced that it will begin building two earthquake-resistant developments near Istanbul; the city of more than twelve million people currently sits near a major fault-line that could potentially kill thousands in the event of a major earthquake; engineers and seismic experts warn that Istanbul’s poor construction, shoddy city planning, and overcrowding would result in many fatalities in the event of an earthquake; officials plan for the new urban centers to be home to roughly 1 million residents each; any move to the new settlements would be entirely voluntary

  • Direct removal of carbon dioxide from air infeasible

    A group of experts looked at technologies known as Direct Air Capture, or DAC, which would involve using chemicals to absorb carbon dioxide from the open air, concentrating the carbon dioxide, and then storing it safely underground; they conclude that these technologies are unlikely to offer an economically feasible way to slow human-driven climate change for several decades

  • New technology quickly detects bioattacks on water supply systems

    If pathogens enter into a city water supply network, many people may fall ill quickly; to protect against this biological threat, researchers have developed a detection system, partly based on nanotechnology, that can warn authorities in time

  • Missouri levee blast floods 130,000 acres, but saves Illinois city

    On Tuesday, the U.S. Army Corps of Engineers blasted a section of a levee along the Mississippi River to create a controlled breach that would relieve pressure and prevent the town of Cairo, Illinois from becoming engulfed in record flood levels; the blast created a gap more than 10,000 feet wide at Birds Point, Missouri levees and inundated more than 130,000 acres of farmland; heavy rains have left the Mississippi and Ohio Rivers swollen, putting Cairo and its 3,000 residents at great risk as it sits on a narrow stretch of land between the two surging rivers; on Monday, the Corps received permission from the federal government to go ahead with its plan, despite Missouri’s protests
