• Disaster relief robots compete at DARPA Robotics Challenge

    Twenty four teams from around the world have just competed in Pomona, California for the Defense Advanced Research Projects Agency’s (DARPA) Robotics Challenge, which runs various rescue robot platforms through a vigorous series of tests to learn and develop better systems. DARPA has made the competition even harder for competing teams. The robots could not operate with power chords, meaning that heavy batteries had to be on the board. Also, there could not be safety pumpers or tools for bipedal robots, which still struggled with balance issues. “In a real disaster, there are no ropes to hold you up. The robots have to drive a car to the door, but the hardest part of the ride is getting out of the vehicle without falling,” said Gill Pratt, program manager of the challenge.

  • Giant foam blocks keep approach slabs of bridges from settling

    The majority of the world’s largest cities, often built in areas near water bodies, have soft and compressible soils. For example, a good number of the 52,000 bridges in Texas have bump problems on entry due to settling of the soil under the pavement slabs. A research team at the University of Texas at Arlington (UTA) is using giant lightweight geofoam blocks to bolster the earth beneath roads and bridges and slow down the settling of roadways and bridges.

  • More than two million California homes at risk as drought continues

    Verisk Insurance Solutions, a Verisk Analytics, has released its 2015 FireLine State Risk Reports, which summarize wildfire risk in thirteen wildfire-prone states. Three new states — Montana, Oklahoma, and Wyoming — are included in this year’s analysis. Among the key findings: There are 4.5 million U.S. homes at high or extreme risk of wildfire, and California ranks first for the highest number of households at high or extreme risk with just over two million — approximately three times the second highest, Texas, with 706,200.

  • A new way of teaching math in schools

    A study has looked at a new way of teaching mathematics in primary and secondary school classrooms, and its ability to enhance learning. The study explored a unique way of delivering a lesson on fractions where teachers provide students with challenging math tasks to work on by themselves or in a group, rather than being instructed on specific solutions. The project found students preferred to work out solutions for themselves, and determine their own strategies for solving problems, rather than following instructions they have been given. The approach could lead to changes to how teachers currently plan their teaching in mathematics, how textbooks are written and how students are assessed.

  • Focusing on how, rather than why, individuals make the transition to terrorism

    Intelligence and counterterrorism officials have spent tremendous effort to understand why people become Islamist terrorists and commit acts of violence. Up till the 1980s, a significant number of terrorism scholars argued that terrorists are “driven” or “pushed” to commit violence because of an internal imbalance or a psychological abnormality rooted inside the individual. In recent years, scholars have suggested that the roots of terrorism are not in the individual, but in the social environment in which terrorists live and act. The debate goes, leading scholars to argue that the concerns of law enforcement officials should be less about why terrorists exist or commit violence, and more about the how, when, and where does the transition to terrorism take place.

  • State-by-state plan to convert U.S. to 100 percent clean, renewable energy by 2050

    One potential way to combat ongoing climate change, eliminate air pollution mortality, create jobs, and stabilize energy prices involves converting the world’s entire energy infrastructure to run on clean, renewable energy. This is a daunting challenge. Now, researchers for the first time have outlined how each of the fifty states can achieve such a transition by 2050. The fifty individual state plans call for aggressive changes to both infrastructure and the ways we currently consume energy, but indicate that the conversion is technically and economically possible through the wide-scale implementation of existing technologies.

  • DHS selects U Illinois for Critical Infrastructure Resilience Center of Excellence

    The U.S. Department of Homeland Security (DHS) Science and Technology Directorate (S&T) yesterday announced the selection of the University of Illinois at Urbana-Champaign as the lead institution to establish a new Critical Infrastructure Resilience (CIRC) Center of Excellence (COE). The university will be supported by a consortium of U.S. academic and industry institutions, S&T will provide CIRC with a $3.4 million grant for its first operating year.

  • Best possible antidote to radicalization: Education

    Education is the best possible antidote to radicalization, Professor Louise Richardson told the British Council’s Going Global conference in London last week. Richardson, who was recently nominated as the next vice-chancellor of the University of Oxford, said: “Any terrorist I have ever met through my academic work had a highly over simplified view of the world, which they saw in black and white terms. Education robs you of that simplification and certitude. Education is the best possible to antidote to radicalization.”

  • Winners of DARPA Robotics Challenge Finals announced

    “May the best robot win” has been a frequently uttered phrase throughout the DARPA Robotics Challenge (DRC) Finals, held this Friday and Saturday at the Fairplex in Pomona, California. After years of research and development, several intense days of preparation at the competition site, a day of rehearsal and two full days of head-to-head competition in front of thousands of spectators, the verdict is in, and three winners were announced Saturday. The Robotics Challenge was launched in response to a humanitarian need that became glaringly clear during the nuclear disaster at Fukushima, Japan, in 2011. The DARPA Robotics Challenge consisted of three increasingly demanding competitions over two years. The goal was to accelerate progress in robotics and hasten the day when robots have sufficient dexterity and robustness to enter areas too dangerous for humans and mitigate the impacts of natural or man-made disasters.

  • NOAA’s new National Water Center will bolster U.S. ability to manage threats to water security

    The National Water Center, a new facility located at the University of Alabama, aims to become an incubator for innovative breakthroughs in water prediction products and services. As the country becomes more vulnerable to water-related events, from drought to flooding, the predictive science and services developed by NOAA and its partners at the National Water Center will bolster the U.S. ability to manage threats to its finite water resources and mitigate impacts to communities. Bringing experts together in this new collaborative center provides an unprecedented opportunity to improve federal coordination in the water sector to address twenty-first century water resource challenges, such as water security, and analysis and prediction of hydrologic extremes, like droughts and floods.

  • Water security key to unlocking African prosperity

    There is mounting evidence of the risks posed by water scarcity to business and economic growth. A 2012 projection by the International Food Policy Research Institute says 45 percent of total GDP — $63 trillion — will be at risk due to water stress by 2050. With coordinated action, better water provision in Africa will strengthen economic growth and unlock the path to prosperity for millions, according to SABMiller’s Chief Executive Alan Clark.

  • Nanosensor bandage measures wound oxygenation

    There is nothing new in the understanding that with combat come injuries, sometimes extreme injuries. In treating and healing wounds, however, physicians must overcome one obstacle which always challenges the healing of wounds: lack of oxygen. Thus, it is necessary to make certain that sufficient oxygen is reaching the healing wound. Chemists have developed a nanosensor bandage which measures the level of oxygen in wounds – a bandage which uses a changing color scheme to inform doctors of the level of oxygen supply in the treated wound.

  • California’s agriculture feels pain of harsh drought

    The California drought is expected to be worse for the state’s agricultural economy this year because of reduced water availability, according to a new study. Farmers will have 2.7 million acre-feet less surface water than they would in a normal water year — about a 33 percent loss of water supply, on average. Reduced availability of water will cause farmers to fallow roughly 560,000 acres, or 6 to 7 percent of California’s average annual irrigated cropland. The drought is estimated to cause direct costs of $1.8 billion — about 4 percent of California’s $45 billion agricultural economy. When the spillover effect of agriculture on the state’s other economic sectors is calculated, the total cost of this year’s drought on California’s economy is $2.7 billion and the loss of about 18,600 full- and part-time jobs.

  • Summer tropical storms do not alleviate drought conditions

    Popular opinion says that tropical storms and hurricanes that make landfall mitigate droughts in the southeastern United States. This simply is not true, according to researchers. According to a NOAA report, 37.4 percent of the contiguous United States was experiencing moderate drought at the end of April – but “The perception that land-falling tropical cyclones serve to replenish the terrestrial water sources in many of the small watersheds in the southeastern U.S. seems to be a myth,” says one of the researchers.

  • DHS selects U Houston as Center of Excellence for Borders, Trade and Immigration Research

    The U.S. Department of Homeland Security (DHS) Science and Technology Directorate (S&T) yesterday announced the selection of the University of Houston as the lead institution for a new DHS Center of Excellence (COE) for Borders, Trade and Immigration Research. S&T will provide the Center for Borders, Trade and Immigration Research with an initial $3.4 million grant for its first operating year.
