• Thermoelectric material converts heat waste to electricity

    Scientists have developed a thermoelectric material which they claim is the best in the world at converting waste heat to electricity; this is very good news, since nearly two-thirds of energy input is lost as waste heat

  • Limiting world trade unlikely to reduce CO2 emissions

    The United States emits less CO2 in the production of its exports than is contained in its imports, simply because it imports more than it exports; only about 20 percent of CO2 transfers from China into the United States can be traced back to the fact that China is in effect relatively more specialized in the production of dirty goods; interventions in world trade, like CO2 tariffs, would probably have only a small impact on global emissions

  • Microstructural improvements enhance material properties

    DARPA merges structural engineering principles with new fabrication technologies to demonstrate microstructural control of materials at the micron level; the ultimate objective of the agency’s Materials with Controlled Microstructural Architecture (MCMA) program is to be able to develop materials in the future with properties tailored to meet specific mission requirements

  • U.S. models underestimates costs of carbon pollution

    Model used by government all but ignores economic damages that climate change will inflict on future generations; two economists argue that when these costs are factored in, the real benefits of carbon reduction range from 2.6 to more than 12 times higher than the government’s estimate

  • Threat-recognition technology incorporates mind, machine

    For soldiers operating in the field, the ability to detect threats from standoff distances can be life-saving; when advanced radar and drone coverage is not available, soldiers typically rely on their own vision to scan their surroundings; DARPA links human brainwaves, improved sensors, and cognitive algorithms to improve target detection 

     

  • Sequestration would result in draconian cuts in biological, medical research

    The Federation of American Societies for Experimental Biology says that sequestration would result in draconian cuts in biological and medical research; the National Institutes of Health (NIH) would be reduced by $2.529 billion, the National Science Foundation would lose $586 million, and the Department of Energy Office of Science would be cut by $400 million

  • New issues of the Journal of Homeland Security Education is available online

    The latest issue of the Journal of Homeland Security Education is out; it contains a number of articles relevant to the teaching of homeland security practices, which is now one of the top ten majors for undergraduates in the United States

  • Harvesting fuel for nuclear reactors from the sea

    Uranium floats in Earth’s oceans in trace amounts of just 3 parts per billion. It is not much, but it adds up; combined, our oceans hold up to 4.5 billion tons of uranium — potentially enough to fuel the world’s nuclear power plants for 6,500 years; researchers propose ways to harvest this uranium

  • Dry-run experiments confirm key aspect of Sandia nuclear fusion concept

    Magnetically imploded tubes called liners, intended to help produce controlled nuclear fusion at scientific “break-even” energies or better within the next few years, have functioned successfully in preliminary tests, according to researchers

  • Four-legged “pack mule” robots demonstrate their capabilities

    Two completed prototype robotic “pack mules” exhibit reduced noise, new gaits, and improved perception, the two functioning platforms have started to run through the paces similar to what they could one day experience carrying gear for a squad of Marines or Soldiers

  • DARPA’s legged robot beats Usain Bolt’s speed record

    Usain Bolt, Olympic gold medalist and world record-holder sprinter, set the world speed record for a human in 2009 when he reached a peak speed of 27.78 mph for a 20-meter split during the 100-meter sprint; DARPA’s Cheetah robot, already the fastest legged robot in history, bested Bolt recently by clocking at 28.3 mph for a 20-meter split

  • U.K.’s first research institute to investigate the science of cyber security

    A new U.K. academic research institute, aiming to improve understanding of the science behind the growing cybersecurity threat, was announced last week; GCHQ, the U.K. intelligence agency, says that the institute, which is funded by a £3.8 million grant, is part of a cross-government commitment to increasing the U.K. academic capability in all fields of cybersecurity

  • Wildfires have both positive and negative economic impacts

    Wildfires disrupt the lives of workers, employers, and families, and lead to longer-term instability in local labor markets, but on the flip side of the coin, countywide employment and wages increase in some sectors during the wildfires, often mitigating the short-term employment disruptions wildfires cause

  • Verizon’s all-hazard approach to disaster preparation

    September is National Preparedness Month in the United States, but Verizon saysits Business Continuity and Emergency Management teams are busy every day of the year monitoring, preparing, and responding to weather-related and man-made events throughout the world; there are 193 member states in the UN, and the company’s BCEM teams are operating in 150 of them and in more than 2,700 cities

  • Thorium to play limited role in U.K. future power supply

    Worldwide, there has for a long time been a sustained interest in the thorium fuel cycle and presently there are several major research initiatives which are either focused specifically on the thorium fuel cycle or on systems which use thorium as the fertile seed instead of U-238; the U.K. National Nuclear Laboratory examined the topic and concluded that thorium has theoretical advantages but that these benefits are often overstated; as a result, thorium fuel cycle at best has only limited relevance to the United Kingdom as a possible alternative plutonium disposition strategy and as a possible strategic option
