• DARPA makes agency-sponsored software, publications available to R&D community

    DARPA has invested in many programs that sponsor fundamental and applied research in areas of computer science, programs which have led to new advances in theory as well as practical software. The R&D community has asked about the availability of results, and now DARPA has responded by creating the DARPA Open Catalog, a place for organizing and sharing those results in the form of software, publications, data, and experimental details. The Web site aims to encourage communities interested in DARPA research to build off the agency’s work, starting with big data.

  • Protecting cities from floods cheaper than post-flood damage repairs

    Researchers say that global warming is here to stay, and thus it is time to start making plans for dealing with the inevitable flooding which will occur as ocean levels rise as a result of warmer water and melting snow and ice. Approximately a billion people currently live in areas which are most at risk — low-lying coastal areas. It is not likely that towns and cities will be moved farther inland, so other measures need to be taken. The researchers say that flood prevention strategies are well established, for example, building levees, barrier islands, etc., so it is not difficult to draw up estimates for such schemes for individual areas.

  • Total California water supplies at near-decade low

    Advisory from UC Center for Hydrologic Modeling finds California’s statewide averages of snow, surface water, and soil moisture near 10-year lows. The threat of multi-year period of unsustainable groundwater depletion imminent if drought continues. The data show particularly steep water losses between November 2011 and November 2013, the early phase of the current drought. The researchers estimate that the Sacramento and San Joaquin River basins have already lost ten cubic kilometers of fresh water in each of the last two years — equivalent to virtually all of California’s urban and household water use each year.

  • Aging grid cannot keep up with growing demand for electricity

    The demand for electricity in the United States increased by around 20 percent from 1999 to 2009, but transmission capacity only increased by around 7 percent in that time. From 2000 to 2004, there were 140 instances of power outages which each affected 50,000 or more consumers. This number increased to 303 from 2005 to 2009. Between 2010 and 2012, there were 226 such outages. The average age of a power plant is 30-years old, and around 75 percent of America’s power lines are 25-years old. Economists estimate that these power outages cost the country more than $70 billion in annual economic loss.

  • Making the U.S. grid sturdier, smarter, and more secure to thwart blackouts

    In August 2003, fifty million customers throughout the northeastern United States and southeastern Canada lost power for up to two days. More than ten years later, the U.S. electric power system continues to be challenged. In the United States, 149 power outages affecting at least 50,000 customers occurred between 2000 and 2004, a number which grew to 349 between 2005 and 2009. In 2012, the prolonged power outages in New York and New Jersey caused by Hurricane Sandy once again demonstrated the system’s vulnerability. A broad, multidisciplinary effort by Georgia Tech researchers aims to revolutionize the delivery of electricity, advance the smart grid, thwart blackouts, integrate renewable energy sources, and secure utilities from cyberattacks.

  • Chemical, defense companies subject to Chinese Nitro attacks

    More and more chemical and defense companies around the world are victims of Nitro attacks. These attacks, launched by government-backed Chinese hackers, install PoisonIvy, a Remote Access Tool (RAT) stealthily placed on computer systems to steal information. The majority of the computers infected belong to firms in the United States, Bangladesh, and the United Kingdom.

  • National Guard units help states ward off cyberattacks

    Governors across the United States are mobilizing their states’ National Guard units to combat threats from cyberattacks. The state of Washington was the first state to assign the state’s National Guard cybersecurity responsibilities. The state recognized the potential of its National Guard as a cyberforce when it realized that many of its soldiers, who are full-time employees and part-time soldiers, worked for tech employers such as Google, Boeing, Cisco, Verizon, and Microsoft.

  • Barrier technology strengthens protection at Navy ports

    Advanced technology rules the day in modern warfare — yet one very real threat to the U.S. Navy comes from a simple but deadly enemy strategy: small speed boats laden with explosives ramming into ships in harbor. Now a new maritime security barrier, developed with support from the Office of Naval Research (ONR), could provide a quantum leap in existing sea-port protection.

  • Senegal climate change-induced flooding reaching crisis proportions: UN

    Margareta Wahlstrom, the head of the UN disaster risk, last week warned that climate change-induced flooding had reached crisis proportions in Senegal, with some towns and villages now finding themselves underwater for large parts of the year. Wahlstrom, who was in Senegal for a 3-day visit as part of the UN preparations for a new global disaster risk-reduction strategy, said that mayors of coastal and riverside towns and villages told her their streets were flooded ten months out of twelve.

  • Clouds influence how greenhouse gases affect climate

    The warming effect of human-induced greenhouse gases is a given, but to what extent can we predict its future influence? That is an issue on which science is making progress, but the answers are still far from exact, say researchers. Indeed, one could say that the picture is a “cloudy” one, since the determination of the greenhouse gas effect involves multifaceted interactions with cloud cover.

  • National cyber complex to open next to Ben-Gurion University of the Negev campus

    A new national cyber complex called CyberSpark will open at the Advanced Technology Park (ATP) which is located next to Ben Gurion University of the Negev. Fortune 500 companies Lockheed Martin and IBM announced they would invest in CyberSpark R&D facilities, joining other cybersecurity leaders Deutsche Telekom, EMC, RSA, and many startups. The 15-building ATP is the only type of complex of its kind in the world that includes Fortune 500 companies and cyber-incubators, academic researchers, and educational facilities as well as national government and security agencies. The CyberSpark will also include a high school geared toward science and technology.

  • Some citizens of low-lying Pacific island nations seeking climate-change refugee status

    More and more resident of Pacific island nations and territories are trying to claim refugee status in Australia and New Zealand, arguing that rising sea levels, caused by climate change, are forcing them out of their homes and destroying their livelihood. The New Zealand High Court has rejected the refugee status petition of Loane Teitota and his family, citizens of Kiribati, a low-lying Pacific Island nation near the equator, saying that Teitota’s argument was “novel” and “optimistic.” The court cautioned that if the argument were adopted, then millions of people suffering from the effects of climate change would seek refugee status in New Zealand or any other country.

  • Increase in wildfires may significantly degrade air quality, health in the future

    As the American West, parched by prolonged drought, braces for a season of potentially record-breaking wildfires, new research suggests these events not only pose an immediate threat to people’s safety and their homes, but also could take a toll on human health, agriculture, and ecosystems.

  • The combination of drought and warming climate places severe strain on California’s water supply

    As stores of water in the West are reduced — whether by usage in drought, evapotranspiration in heat, or both — warming temperatures also see the snowpack on the wane. The two phenomena together could put severe strain on water supplies, with implications for ecosystems, industries, and people alike. Even at their most severe, the droughts of decades and centuries past did not occur in tandem with today’s degree of temperature change or have to contend with the demands of a population that in California alone now numbers above thirty-eight million residents. As needs for water grow ever greater, so, too, do the potential threats to its supply.

  • The world likely to face more frequent, and more severe, blackouts

    U.S. household electricity usage increased by 1,300 percent between 1940 and 2001. In the last few decades, air conditioning has been the greatest factor in increased electrical consumption, and one of the greatest sources of systematic strain, with considerably more blackouts occurring in the summer months than during winter. The electricity used to fuel America’s air conditioning is currently of a similar volume to the U.S. entire energy consumption in the 1950s. A new study reveals that today’s occasional blackouts are dress rehearsals for the future, when they will occur with greater frequency and increased severity. Power cuts will become more regular around the globe as electrical supply becomes increasingly vulnerable and demand for technology continues to grow at an unprecedented rate.
