• World's first grid-scale isothermal compressed air energy storage system

    A New Hampshire company has completed construction and begun startup of the world’s first megawatt-scale isothermal compressed air energy storage (ICAES) system. The system stores and returns megawatts of electricity to provide long-term grid stability and support integration of renewable energy sources like wind and solar. Unlike chemical battery systems, ICAES performance does not degrade over its lifetime or need frequent replacement. No hazardous materials are used.

  • History of explosives highlighted in museum exhibit

    For more than seventy years, Los Alamos National Laboratory has been a frontrunner in explosives research, development, and applications. To highlight the Laboratory’s work in the field of explosives, the Bradbury Science Museum is opening a new exhibit, titled “The Science of Explosives.”

  • October is National Cybersecurity Awareness Month

    This October marks the tenth National Cyber Security Awareness Month (NCSAM), an effort to educate millions of people each year about the importance of online safety and security. During the month, leaders from the public and private sectors will come together to advance its universal theme that protecting the Internet is “Our Shared Responsibility.”

  • Sewage treatment removes widely used home and garden insecticides from wastewater

    Even though sewage treatment plants are not designed to remove tiny amounts of pesticides, they do an excellent job of dealing with the most widely used family of home and garden insecticides, scientists reported. The use of pyrethrins, derived from chrysanthemum flowers, and the related synthetic pyrethroids, has been on the increase during the last decade. Researchers found that advanced sewage treatment reduced the levels of pyrethroids by more than 97 percent.

  • Calculating the cost of a ton of mountaintop removal coal

    To meet current U.S. coal demand through surface mining, an area of the Central Appalachians the size of Washington, D.C., would need to be mined every eighty-one days. This is about sixty-eight square miles — or roughly an area equal to ten city blocks mined every hour. A 1-year supply of coal would require converting about 310 square miles of the region’s mountains into surface mines.

  • Unified military intelligence picture dispels the fog of war

    Military operations depend upon the unimpeded flow of accurate and relevant information to support timely decisions related to battle planning and execution. To address these needs, numerous intelligence systems and technologies have been developed over the past twenty years, but each of these typically provides only a partial picture of the battlefield, and integrating the information has proven to be burdensome and inefficient. DARPA’s Insight program aims to bring real-time, integrated, multi-source intelligence to the battlefield.

  • Beer-Sheva Cyber Security Park inaugurated by Prime Minister Benjamin Netanyahu

    The development of the Negev took a step forward earlier this month with the inauguration of Beer-Sheva’s Advanced Technologies Park (ATP) in which Ben-Gurion University of the Negev (BGU) is the academic research partner. Israel prime minister Benjamin Netanyahu presided over the ribbon-cutting ceremony on 3 September.

  • Canada addresses environmental concerns over Keystone XL

    Canadian prime minister Stephen Harper sent a letter to President Barack Obama last month offering to participate in joint efforts to reduce greenhouse-gas emissions in order to win approval of the Keystone XL Pipeline. Harper’s offer may allow Obama to approve the project without having to confront environmental groups.

  • Cold-formed steel rebuilds earthquake-resistant architecture

    When engineers attempt to make a building earthquake-resistant, they use specific structural components, appropriately called details, to absorb earthquake forces and help direct some of those forces back to the ground. That works, but when an earthquake hits, the entire building reacts, not just the sections containing details. Even though academic research has led to improvements to the original building codes over the decades, there is much to be learned about the entire system of a cold-formed steel building as it responds to an earthquake.

  • Calculating the energy required to store wind and solar power on the grid

    Renewable energy holds the promise of reducing carbon dioxide emissions. There are times, however, when solar and wind farms generate more electricity than is needed by consumers. Storing that surplus energy in batteries for later use seems like an obvious solution, but a new study from Stanford University suggests that might not always be the case.

  • New technique developed to assess the cost of major flood damage

    A new approach to calculating the cost of damage caused by flooding was presented at the International Conference of Flood Resilience: Experiences in Asia and Europe which was held last week. The methodology combines information on land use with data on the vulnerability of the area to calculate the cost of both past and future flooding events.

  • Bomb-detecting lasers to improve security checkpoints

    Research has put the possibility of bomb-detecting lasers at security checkpoints within reach by developing a laser that can detect micro traces of explosive chemicals on clothing and luggage. The laser not only detects the explosive material, but it also provides an image of the chemical’s exact location, even if it’s merely a minute trace on a zipper.

  • Researchers fabricate new camouflage coating from squid protein

    What can the U.S. military learn from a common squid? A lot about how to hide from enemies, according to researchers. Researchers show that material that mimics calamari skin is invisible to infrared cameras, which is a good thing since infrared detection equipment is employed extensively by military forces for night vision, navigation, surveillance, and targeting.

  • “Climate Change, Water Conflicts, and Human Security” report released

    Increasingly, climate change and the associated increase in the frequency of extreme weather events such as floods, droughts, and rising sea level, are acknowledged as not only having humanitarian impacts, but also creating national and regional political and security risks. While people and governments can adapt to these impacts, their capacity to do so varies.

  • Study links prehistoric climate shift to asteroid or comet impact

    For the first time, a dramatic climate shift which has long fascinated scientists has been linked to the impact in Quebec of an asteroid or comet. The event took place about 12,900 years ago, at the beginning of the Younger Dryas period, and marks an abrupt global change to a colder, dryer climate, with far-reaching effects on both animals and humans.
