• Missed opportunities to save water, energy

    Water and wastewater managers are missing substantial opportunities to save energy and money, according to a new report.The report also identifies significant gaps in knowledge about the amount of water used to extract energy resources such as natural gas, oil, and coal, and to generate electricity.

  • Teams show robust radio techniques at Spectrum Challenge event

    Radios are used for a wide range of tasks, from the most mundane to the most critical of communications, from garage door openers to first responders to military operations. Wireless devices often inadvertently interfere with and disrupt radio communications, and in battlefield environments adversaries may intentionally jam friendly communications. To stimulate the development of radio techniques that can overcome these impediments, the agency launched its Spectrum Challenge — a competitive demonstration of robust radio technologies that seek to communicate reliably in congested and contested electromagnetic environments without direct coordination or spectrum preplanning.

  • Congress urged to support broad legislative agenda for science

    With the U.S. Senate poised to revisit S. 1392, the Energy Savings and Industrial Competitiveness Act of 2013, the American Chemical Society (ACS) announced its support for the bill as part of a larger, legislative science agenda for 2013.

  • Flood insurance is not available to Canadian homeowners – should it be?

    Canada is the only G8 country in which insurance against overland flooding is not available to homeowners — but does it have to remain that way? A study released Monday explores issues related to flooding and property insurance, aiming to advance informed discussion of the potential better to protect Canadian homeowners. It reveals that while insurance executives are concerned about the lack of flood insurance and agree on many of the associated issues, opinions remain mixed concerning its viability in Canada.

  • Microbial power storage can do the job

    Oil and gas can be converted into electricity in line with demand, but wind, water, and sun cannot be adapted as readily to fluctuations in power consumption. Efficient power storage solutions must satisfy two essential criteria: Their own consumption of resources must be as low as possible, and surplus power must be stored within seconds. The results of a pilot study have now demonstrated that a microorganism-based process developed by is unequalled in the way it satisfies both of these criteria.

  • Smartphone “microscope” can detect a single virus, nanoparticles

    Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair. Researchers have created a portable smartphone attachment that can be used to perform sophisticated field testing to detect viruses and bacteria without the need for bulky and expensive microscopes and lab equipment. The device weighs less than half a pound.

  • Extracting maximum energy from currents

    In the long sprint to find new sources of clean, low-cost power, slow and steady may win the race — the slow-moving water of currents and tides, that is. Just as wind turbines tap into the energy of flowing air to generate electricity, hydrokinetic devices produce power from moving masses of water.

  • 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.
