• Geologists: Sandy could happen again

    Sandy’s storm surge hit the coast at high tide, but storm and tidal conditions were not the only cause of the devastation. Seawaters off New York’s coast have risen sixteen inches since 1778, the year of New York City’s first major recorded storm. Geologists say that due to rising sea levels, smaller storms could produce significant flooding.

  • New barrier system to protect Venice from rising seas

    The City of Venice, Italy has carried out the first test of its $7.3 billion barrier system designed to protect the city from rising sea levels. The system, known as MOSE (MOdulo Sperimentale Elettromeccanico), consists of seventy-eight mobile barriers divided into four sections at the three inlets to the Venice lagoon.

  • Using hills to shelter buildings from tornadoes

    Researchers have demonstrated the influence of hills on tornadoes. The researchers’ models revealed that the height of a hill and the size of a tornado’s vortex have a significant effect on the tornado’s destructive power. The findings could be used to identify safer areas for construction.

  • U.S. formulates strategy for a new Arctic landscape

    U.S. national security officials have become increasingly concerned about the national security implications of an ice-free Arctic. The Arctic will become ice-free during the summer by mid-decade. In a strategy document, the Pentagon says: “Melting sea ice in the Arctic may lead to new opportunities for shipping, tourism, and resource exploration, but the increase in human activity may require a significant increase in operational capabilities in the region in order to safeguard lawful trade and travel and to prevent exploitation of new routes for smuggling and trafficking.”

     

  • Coast Guard to discuss new U.S. Arctic strategy

    The future of the Arctic has become a hot topic in U.S. national security, energy, and policy circles. The Washington Homeland Security Roundtable (WHSR) has organized a forum for private-sector leaders in which Vice Admiral Peter Neffenger, deputy commandant for operations of the U.S. Coast Guard (USCG), and Captain Jon Spaner, USCG director of emerging policy, will discuss the ramifications of climate-driven changes in the Arctic for U.S. national security and maritime operations, and share insights on the role of the USCG in meeting the challenges posed by a new ocean created by rapidly melting ice.

  • Maryland preparing for sea level rise

    Maryland has 3,100 miles of tidal shoreline. A scientific report recommends that it would prudent for the state to prepare for a sea level rise of 1.4 feet by 2050.Maryland’s CoastSmart Communities Initiative (CCI) provides grant funding for coastal communities which want to reduce their vulnerabilities to the effects of coastal hazards and sea level rise by becoming ready, adaptive, and resilient.

  • Snake robots move quickly in confined spaces, rough terrain

    Snakes usually travel by bending their bodies in the familiar S-pattern. When they are stalking prey, however, snakes can move in a straight line by expanding and contracting their bodies. This “rectilinear gait” is slow, but it is quiet and hard to detect—-a perfect way to grab that unsuspecting rodent. This “limbless locomotion” is a highly effective way for a robot to move through cluttered and confined spaces.

  • Renewable fuel standard: mend it, don’t end it

    Congress should minimally modify — and not, as petroleum-related interests have increasingly lobbied for, repeal — the Renewable Fuel Standard (RFS), the most comprehensive renewable energy policy in the United States, according to a new paper. The paper argues that RFS mandates merely ought to be adjusted to reflect current and predicted biofuel commercialization realities.

  • U.S. elementary school math: Half-century of problematic approach

    During the “New Math” movement of the 1960s, a team of mathematicians developed a new structure for elementary mathematics. Instead of having a single subject, namely, school arithmetic, as its central core, this new structure instead had eight “strands” that were supposed to tie together elementary mathematics content. The strands structure has persisted to this day. A new paper argues that the strands structure has significantly weakened U.S. school mathematics.

  • ASCB: U.S. scientific research will "pay dearly" for shutdown

    The American Society for Cell Biology (ASCB) added its voice to those of other scientific and professional groups in warning that the federal government’s partial shutdown will hurt patients, researchers, and especially the U.S. research effort, long after an agreement to end the impasse is reached. “As America keeps hitting the brakes on scientific research, we are, in effect, accelerating the damage done to our continued leadership in global bioscience, in health outcomes and in the economic power that we have always derived from basic research,” Dr. Bertuzzi, executive director of the ASCB said. “Americans will pay dearly for these slowdowns, sequestrations, and shutdowns in finding cures and on maintaining economic competitiveness.”

  • Sea power: extracting energy from ocean waves

    As sources of renewable energy, sun and wind have one major disadvantage: it is not always sunny or windy. Waves in the ocean, on the other hand, are never still. Researchers are now aiming to use waves to produce energy by making use of contact electrification between a patterned plastic nanoarray and water.

  • Compact, high-power terahertz source at room temperature developed

    Terahertz (THz) radiation — radiation in the wavelength range of 30 to 300 microns — is gaining attention due to its applications in security screening, medical and industrial imaging, agricultural inspection, astronomical research, and other areas. Traditional methods of generating terahertz radiation usually involve large and expensive instruments, some of which also require cryogenic cooling. Researchers have developed a compact, room-temperature terahertz source with an output power of 215 microwatts.

  • ACS: Shutdown undermines U.S. innovation, competitiveness, critical services

    American Chemical Society (ACS) president Marinda Li Wu said that the budget impasse is effectively choking America’s science innovation pipeline, strangling new discoveries, future economic growth, and job creation. “[T]o shut down a critical part of our nation’s research and innovation pipeline puts our nation at a severe competitive disadvantage globally,” said Wu. “A government shutdown that closes the world’s largest research system can lead to unintended negative consequences putting at peril America’s economic growth and long-term stability.”

  • Research investments, growing markets drive rise in energy patents

    Innovation in energy technology is booming, according to a new paper which examines what factors set the pace for energy innovation. The study finds that investments in research and development, as well as in the growth of markets for these products, have helped to spur this dramatic growth in innovation.
