• Fundamental changes needed in the education of tomorrow’s scientists

    Fundamental changes are needed in the education of the scientists whose work impacts medicine, drug discovery, development of sustainable new fuels, and other global challenges society is facing in the twenty-first century. Those changes in graduate education in chemistry were the topic of a special symposium the other day at the 245th National Meeting & Exposition of the American Chemical Society.

  • More border security means more business opportunities for tech companies

    At last month’s Border Security Expo in Phoenix, both start-ups and established companies showed off their inventions in an effort to pitch projects to federal agencies. Two themes emerged in the show: the expo demonstrated that many of the systems and weapons systems that were used in the Iraq and Afghanistan wars are now becoming available to local, state, and federal law enforcement agencies – and companies expressed concern about the impact the federal budget cuts will have on their pockets.

  • L.A County to turn rain water into drinking water

    Residents of Los Angeles County know that on the rare occasion that it rains, staying away from the beach is a good idea. Runoff from rain typically brings heavy metals, pesticides, cigarette butts, animal waste, and other pollutants  into the streams and rivers which go into the Pacific Ocean. Now, local officials are getting together to find a solution to the water pollution and water scarcity, with an ambitious plan to make the runoff water drinkable.

  • Finding the right tools to respond to suspicious powder incidents

    HazMat teams across the United States respond to hundreds of white powder calls each year in large cities where quick decision-making is critical. DHS makes it easier to buy the right technology for bio-threat incidents.

  • Oregon citizens preparing for the Big One

    A new study concludes that an earthquake of a magnitude 8.0 or above will strike off the coast of the state within the next fifty years. The Cascadia Fault, which runs from Northern California to British Columbia, Canada, causes a massive earthquake every 300 years or so, and the last time an earthquake hit the region was in the year 1700.

  • Making concrete “greener”

    Many factors determine the overall energy and environmental impact of concrete. Reducing the amount of portland cement, which reacts with water to bind all the sand, stone, and the other constituents of concrete as it hardens, provides the biggest opportunity. Portland cement manufacturing accounts for more than 5 percent of U.S. industrial carbon-dioxide emissions. In addition, the U.S. cement industry consumes 400 gigajoules of energy annually.

  • Nuclear fusion could power a rocket to take humans to Mars

    NASA estimates a round-trip human expedition to Mars would take more than four years using current technology. The sheer amount of chemical rocket fuel needed in space would be extremely expensive — the launch costs alone would be more than $12 billion. Now, astronauts could be a step closer to our nearest planetary neighbor through a manipulation of nuclear fusion, the same energy that powers the sun and stars.

  • Renewable energy could economically replace fossil-based energy in Australia

    A carbon price of between AU$50 and AU$100 per ton of carbon dioxide would make coal-fired and gas-fired power in Australia less economical than renewable electricity. A new study says that all fossil-fuelled power stations in Australia’s National Electricity Market could be phased out and replaced economically and reliably with commercially available renewable energy technologies by increasing the carbon price to this “medium” level.

  • U.S. nuclear industry faces a wave of nuclear power station retirements

    A wave of U.S. nuclear power station retirements is on the horizon. The typical design life of a nuclear power plant is 40 years. There are 104 nuclear power plants in the United States, and their average age is 34 years — only a few years short of, and fast approaching, their design life. Almost 30 U.S. commercial and research reactors already have started decommissioning. A $400 million is regarded as the bargain basement price tag for cleaning up a single reactor.

  • DHS launches Campus Resilience pilot program

    DHS secretary Janet Napolitano announced Tuesday that seven universities will participate in a national preparedness initiative designed to help campuses train for, respond to, and recover from an emergency situation.

  • Fully secure communication

    Can worldwide communication ever be fully secure? Quantum physicists believe they can provide secret keys using quantum cryptography via satellite. These physicists have, for the first time, successfully transmitted a secure quantum code through the atmosphere from an aircraft to a ground station.

  • China catches 12 times more fish beyond its waters than it reports

    Chinese fishing boats catch about $11.5 billion worth of fish from beyond their country’s own waters each year — and most of it goes unreported. Researchers estimate Chinese foreign fishing at 4.6 million tons per year, taken from the waters of at least ninety countries — including 3.1 million tons from African waters, mainly West Africa.

  • Same-day water test keeps beaches open, swimmers’ health protected

    With warm summer days at the beach on the minds of millions of winter-weary people, scientists are reporting that use of a new water quality test this year could prevent unnecessary beach closures, while better protecting the health of swimmers.

  • Exploring the human brain to support national security

    The other day, at a White House event, President Barack Obama unveiled a new research initiative designed to revolutionize the understanding of the human brain. DARPA plans $50 million in 2014 investments to translate this increased understanding of brain function to create new capabilities.

  • Large robotic jellyfish to patrol the oceans

    The Office of Naval Research wants to place self-powering, autonomous machines in waters for the purposes of surveillance and monitoring the environment, in addition to other uses such as studying aquatic life, mapping ocean floors, and monitoring ocean currents. Researchers have built a device for that purpose — a life-like, autonomous robotic jellyfish the size and weight of a grown man, 5 foot 7 inches in length and weighing 170 pounds.
