• 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

  • Lessons learned: Cheech and Chong at the Y-12 security breach

    By Lee Maril

    On 28 July 2012, an 82-year old nun and her two confederates — both senior citizens themselves – breached the vaunted and supposedly impregnable perimeter protection system at the Y-12 National Security Complex at Oak Ridge, where uranium for nuclear weapons is processed and stored (the Y-12 complex is not affiliated with the Oak Ridge National Laboratory [ORNL]); a report on the incident by the Inspector General of the Department of Energy is couched in bureaucratic jargon, but it reveals that the Y-12 security system and practices were much worse than Cheech and Chong could have ever portrayed in their wildest stand-up comedy routines or loopy films

  • New law aims to make Istanbul earthquake-safe, but it has its critics

    Estimates of Istanbul’s population range from twelve and nineteen million people, a significant increase from two million people fiftyyears ago; during the waves of migration to Istanbul during the 1960s,1970s, and 1980s, the government gave citizens free permitsto add to their homes, which resulted in single-story residents becoming 4-or 5-story buildings on unstable foundations; Istanbul sits only thirteen miles north of the North Anatolian Fault, the intersection of the Eurasian and Anatolian plates, and has been subject to devastating earthquakes; new, controversial law aims to make Istanbul’s buildings earthquake-safe

  • 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

  • Boeing to pursue cybersecurity opportunities in Japan

    Boeing and Japanese trading company Sojitz are teaming up to offer advanced cybersecurity solutions in Japan to help protect critical government, civil, and commercial information technology infrastructure

  • 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

  • Nexans shows its anti-theft cable solutions

    Nexans is showing its new anti-theft cable solutions at InnoTrans, which opened yesterday in Berlin; the solution promises to help network operators reduce the high volume of copper cables theft along their railway networks

  • 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

  • Nuclear waste-burning technology to make nuclear energy more appealing

    Toxic nuclear waste is stored at sites around the United States, and the need to store nuclear waste is widely considered to be a major disadvantage associated with nuclear energy; physicists have been granted a U.S. for patent for a novel fusion-fission hybrid nuclear reactor which would use nuclear fusion and fission together; the invention could drastically decrease the need for any additional or expanded geological repositories, making nuclear power cleaner and more viable

  • Nanotechnology sensor detects mercury in water, fish

    When mercury is dumped into rivers and lakes, the toxic heavy metal can end up in the fish we eat and the water we drink; to help protect consumers from the diseases and conditions associated with mercury, researchers have developed a nanoparticle system that is sensitive enough to detect even the smallest levels of heavy metals in our water and fish

  • Many Americans exposed to drinking water-related gastrointestinal illness

    More than 100 million people in the United States rely on water piped into homes, schools, and businesses from public water systems that get their water from wells, rather than lakes, rivers, and other above-ground sources; much of that water either is not disinfected at all or is not adequately disinfected to kill disease-causing viruses

  • At least 200,000 tons of oil, gas from Deepwater Horizon spill consumed by bacteria

    Researchers have found that, over a period of five months following the disastrous 2010 Deepwater Horizon explosion and oil spill, naturally occurring bacteria which exist in the Gulf of Mexico consumed and removed at least 200,000 tons of oil and natural gas that spewed into the deep Gulf from the ruptured well head
