• Sea levels are rising ahead of predictions; scientists explain why

    The last official Intergovernmental Panel on Climate Change (IPCC) report in 2007 projected a global sea level rise between 0.2 and 0.5 meters by the year 2100; current sea-level rise measurements meet or exceed the high end of that range and suggest a rise of one meter or more by the end of the century; scientists meeting next week at the Geological Society of America annual meeting will discuss whether estimates of the rate of future sea-level rise are too low

  • Rising sea levels make NYC vulnerable to more frequent, more intense floods

    Scientists say that Hurricane Sandy has forced a recognition on New York City and on other coastal communities: the steady rise in sea levels means not only more floods, but more frequent and more devastating floods; three of the top 10 highest floods at the Battery since 1900 happened in the last two and a half years; after rising roughly an inch per decade in the last century, coastal waters in New York are expected to climb as fast as six inches per decade, or two feet by midcentury; the city is exploring a $10 billion system of surge barriers and huge sea gates

  • Study connects burning fossil fuels to sea level rise

    A study has found that burning all the Earth’s reserves of fossil fuels could cause sea levels to rise by as much as five meters — with levels continuing to rise for typically 500 years after carbon dioxide emissions ceased

  • Death, destruction in wake of Hurricane Sandy

    Hurricane Sandy’s left millions along the U.S. East Coast without power or mass transit, in all likelihood for days; the U.S. death toll reached 48, with most of the dead being killed by falling trees; the hurricane cut power to more than 8.2 million across the East Coast; airlines canceled more than 15,000 flights; Sandy will end up causing about $20 billion in property damage and $10 billion to $30 billion more in lost business, making it one of the costliest natural disasters on record in the U.S. history

  • Improving high-speed rail ties against freezing, thawing conditions

    Research project is helping high-speed rail systems handle the stress of freezing and thawing weather conditions; the 3-year study looks at the freeze-thaw durability of concrete railroad ties; the research is essential to developing safe and durable high-speed rail systems

  • Hurricanes will test Florida buildings, built under new, post-Wilma building codes

    In 2005 Hurricane Wilma was responsible for five deaths and millions of dollars worth of damage in Florida; building codes in the state were updated, and experts predict that these new buildings, most of which were designed with wind-tunnel testing, should perform well in all but the most severe conditions

  • Thawing permafrost to release nitrogen, carbon – doubling the amount of carbon in the atmosphere today

    As much as forty-four billion tons of nitrogen and 850 billion tons of carbon stored in arctic permafrost, or frozen ground, could be released into the environment as the region begins to thaw over the next century as a result of a warmer planet; for context, this is roughly the amount of carbon stored in the atmosphere today

  • Asteroid DA14 will be whizzing by Earth on 15 February -- the closest asteroid fly by in history

    On 15 February 2013, asteroid 2012 DA14, the size of a city block, will be whizzing within 14,000 miles of Earth, squeezing between Earth’s atmosphere and the geostationary satellites orbiting the planet; it will be the closest asteroid fly by in history; experts say there is no chance the asteroid will hit Earth — this time; with more than 4,700 asteroids NASA has identified as potential threats to Earth, however, some as big as sixteen football fields, these objects are getting a lot of attention

  • Paintballs may deflect an incoming asteroid

    By Jennifer Chu

    With twenty years’ notice, paint pellets could cause an asteroid to veer off course; researchers say that, if timed just right, pellets full of paint powder, launched in two rounds from a spacecraft at relatively close distance, would cover the front and back of an asteroid, more than doubling its reflectivity, or albedo; the initial force from the pellets would bump an asteroid off course; over time, the sun’s photons would deflect the asteroid even more

  • Safety glass – cut to any shape

    If an object slams into the glass façade of a high-rise building, the glass must not shatter and fall down, because it could harm pedestrians below; in addition, the window panes must hold if a person were to fall against it from the inside; architects and builders must therefore use something stronger than laminated safety glass on the façades of high rise buildings; scientists develop a method which offers more flexibility with the design and handling of safety glass

  • Scientists improving process to recycle rare-earth materials

    Recycling keeps paper, plastics, and even jeans out of landfills. Could recycling rare-earth magnets do the same? Perhaps, if the recycling process can be improved; scientists are working more effectively to remove the neodymium, a rare earth element, from the mix of other materials in a magnet; initial results show recycled materials maintain the properties that make rare-earth magnets useful

  • Kaspersky Lab working on a secure operating system for critical infrastructure

    Antivirus firmKaspersky Lab is set to make a major contribution to the security of critical infrastructure systems by developing an operating system specifically designed for such systems; the new operating system will protect information used in infrastructure such as nuclear power plants, transportation control facilities, gas and electrical systems,and other  facilities “criticallyimportant” to the economy and well-being of industrialized societies

  • Assessing bridge resilience

    Across the United States, more than 600,000 bridges link travelers to millions of roadway miles, forming a critical part of the nation’s infrastructure; because bridges are typically more vulnerable than roadways to damage caused by natural and man-made hazards, they are also of interest to DHS, which funds cutting-edge research in various aspects of structural integrity testing and blast-resistant structural design

  • Analyzing the sound of rain falling on a bridge reveals bridge’s health, stability

    Engineers have found that by listening to how a highway bridge sings in the rain, they can determine serious flaws in the structure; employing a method called impact-echo testing, engineers can diagnose the health of a bridge’s deck based on the acoustic footprint produced by a little bit of water

  • Cybersecurity bill supporters want a vote on bill in this Congress

    Last week, lawmakers and top White House officials appeared in different events, conferences, and industry gatherings to promote the cyber security bill which has been stalled in the Senate since August; administration’s officials and lawmakers supporting the bill warned that the current situation leaves U.S. critical infrastructure and businesses vulnerable to attack from hackers and spies
