• Future warming likely to be on high side of climate projections: analysis

    Climate model projections showing a greater rise in global temperature are likely to prove more accurate than those showing a lesser rise, according to a new analysis by scientists at the U.S. National Center for Atmospheric Research (NCAR); NCAR says that the findings could provide a breakthrough in the longstanding quest to narrow the range of global warming expected in coming decades and beyond

  • Intensive farming with a climate-friendly touch

    In the world of agriculture, climate protection and intensive farming are generally assumed to be a contradiction in terms; scientists have come up with a new land development concept that could change this view; the new model is tailored to medium-sized farms in South America and sees farmers transitioning from large-scale monoculture to more diverse crop mixtures spread over smaller plots interspersed with wooded areas — a switch that can bring significant financial benefits

  • Nor'easter batters NYC, New Jersey

    A nor’easter battered New York and New Jersey on Wednesday with rain and wet snow, plunging homes back into darkness, stopping commuter trains, and inflicting yet more misery on thousands of people still trying to recover from Superstorm Sandy; ordinarily, the nor’easter would not pose major problems, but this was not the case yesterday, as the storm hit an area where electrical systems were still fragile and many of Sandy’s victims still busy cleaning their homes and coping with deepening cold

  • MIT researchers develop method to help communities plan for climate risk

    As the devastation left by Sandy continues to reverberate, decision-makers at every level are asking: How can we be better prepared? MIT researchers developed a tool to assess regional risks of climate change and potential impacts on local infrastructure and planning; the tool helps policymakers, city planners, and others see the possible local effects of climate change, such as long-term temperature and precipitation changes, allowing local planners to evaluate risks, and how these risks could shape crops, roads, and energy infrastructure

  • Building material of millennium: Autoclave Aerated Concrete

    Although widespread rebuilding in the hard-hit New York metro region from Hurricane Sandy has not yet begun, New Jersey Institute of Technology (NJIT) scientists say when the hammers start swinging, it is time to look at autoclaved aerated concrete; the material, best known as AAC, has been heralded as the building material of the new millennium

  • Nanostructured material stronger than a speeding bullet

    Providing protection against impacts from bullets and other high-speed projectiles is more than just a matter of brute strength; while traditional shields have been made of bulky materials such as steel, newer body armor made of lightweight material such as Kevlar has shown that thickness and weight are not necessary for absorbing the energy of impacts; new tests of nanostructured material could lead to better armor against everything from gunfire to micrometeorites

  • DARPA seeks multi-band, portable sensor to provide soldiers with clear images

    Clip-on or helmet-mounted camera system would fuse useful aspects of visible, near infrared, and infrared images into a single shot under all weather and visibility conditions; the Pixel Network for Dynamic Visualization program, or PIXNET, technology would ingest the most useful data points from each component sensor and fuse them into a common, information-rich image that can be viewed on the soldier’s heads-up display, and potentially be shared across units

  • The limitations of climate models

    How accurate is the latest generation of climate models? Climate physicists have compared them with old models and draws a differentiated conclusion: while climate modeling has made substantial progress in recent years, we also need to be aware of its limitations

  • Scientists resurrect process to convert sugar directly to diesel

    A long-abandoned fermentation process once used to turn starch into explosives can be used to produce renewable diesel fuel to replace the fossil fuels now used in transportation; the retooled process produces a mix of products that contain more energy per gallon than ethanol that is used today in transportation fuels and could be commercialized within 5-10 years

  • Inflatable giant plugs could have saved NYC subway system

    Inflatable plugs being developed with funding from DHS, could have saved some of New York’s subway and highway tunnels from flooding during Hurricane Sandy, according to the developers of the plugs; DHS successfully tested a plug earlier this year, using a 16-foot diameter prototype to hold back pressurized water at a test tunnel in Morgantown, West Virginia; the idea was originally intended to protect tunnels from terrorist attacks

  • Dutch flood-protection may be suitable for New York, other East Coast cities

    Megastorms and disasters are not going to continue to be once in a lifetime storms, but instead become more of an annual occurrence; experts say that the combination of more frequent megastorms and rising sea levels across the east coast would forcemany cities to get serious about flood protection

  • New strategy for fingerprint visualization

    Identifying fingerprints on paper is a commonly used method in police forensic work, but it is not easy to make those fingerprints visible. Now, scientists have developed a new approach for making such fingerprints more readily readable

  • Long-term sea level rise could cost Washington, D.C. billions

    New study projects that the city of Washington, D.C., and federal property in the city, could suffer billions of dollars in damage if sea level rise as a result of global warming increases over the next century. Potential for significant damage will be even greater in the event of extreme weather like Hurricane Sandy

  • 2011 Virginia quake triggered landslides very far away

    The 2011 Mineral, Virginia M-5.8 earthquake was felt over an extraordinarily large area; a new study details landslides triggered by the earthquake at distances four times greater and over an area twenty times larger than previously documented for M-5.8 earthquakes worldwide

  • Indian monsoon failure more frequent with warming

    Global warming could cause frequent and severe failures of the Indian summer monsoon in the next two centuries, new research suggests; the effects of these unprecedented changes would be extremely detrimental to India’s economy which relies heavily on the monsoon season to bring fresh water to the farmlands
