• Urgent need to find asteroids that threaten Earth: expert

    The impact from a 100-meter long asteroid hitting Earth would be equal to detonating a 100-megaton hydrogen bomb. Several large asteroids have zipped dangerously close to Earth in the past month. There are millions of these near-Earth-orbit (NEOs) asteroids longer than 100 meters. Because they are relatively small, and because they spend so much time far from Earth, scientists tend to find them only by chance.

  • Russia embarking on a program to thwart asteroid threat

    Officials from Rosatom, Russia’s nuclear agency, and from Russia’s space agency, yesterday (Tuesday) told a special conference at the Russian Federation Council, the Russian upper house, that Russia was embarking on an ambitious program – estimated to cost about $2 billion – to shield Russia from the threat of asteroids and meteors. The first steps will be taken by the end of the year, but the comprehensive set of measures will not be available until 2018-20. The officials discussed various possible measures, ranging from planting beacon transmitters on asteroids to megaton-sized nuclear strikes to destroy asteroid or divert them from a course which would lead to a collision with the Earth.

  • Missouri looking for ways to fund infrastructure repairs

    As is the case in other states, Missouri faces “a huge backlog of repair and maintenance needs” in its infrastructure, in the words of a state lawmaker. Lawmakers debate bond issue, increase in state sales tax, and other measures to fund the necessary repairs.

  • Making future sea-level predictions more accurate

    Sea-level rise is a major issue facing those in charge of infrastructure protection in coastal communities. New research into radiocarbon dates of tiny fossilized marine animals found in Antarctica’s seabed sediments offers new clues about the recent rapid ice loss from the West Antarctic Ice Sheet and helps scientists make better predictions about future sea-level rise. 

  • Napolitano testifies on cybersecurity executive order

    Two Senate panels questioned DHS Secretary Janet Napolitano yesterday at a hearing on President Obama’s cybersecurity executive order and what issues need to be addressed in cyber legislation. “We simply cannot afford to wait any longer to adequately protect ourselves,” Said Senator Jay Rockefeller (D-West Virginia), chairman of the Senate Commerce Committee.

  • Tech companies, telecoms clash over cybersecurity executive order

    Last August a cybersecurity bill died in Congress amid partisan bickering. On 12 February this year, President Obama packed many of that bill’s elements into a cybersecurity executive order. To make the order more acceptable to some of its congressional and industry critics, the president introduced an exemption which would take large technology companies off the list of companies subject to the new cybersecurity standards. This exemption placated some of the original cybersecurity bill’s critics, but angered others, chief among them telecommunication companies.

  • Precious metal recovery technique ideal for rare Earth elements purification

    Researchers have come up with a new approach to make the recovery of high value precious metals faster and more economically viable. The new technique could be ideal for the purification of rare earth elements, which are vital commodities for ‘green’ technologies such as hybrid cars and novel batteries.

  • New source for rare earth elements: discarded consumer products

    In a new twist on the state’s mining history, a group of Idaho scientists will soon be crushing consumer electronics rather than rocks in a quest to recover precious materials. Two national labs  in the state will apply expertise gained in recycling fissionable material from nuclear fuel to separate rare earth metals and other critical materials from crushed consumer products.

  • Norfolk, Virginia, tries to cope with sea-level rise

    Norfolk, Virginia, is home to the largest U.S. naval base in the country, and the second biggest commercial port on the U.S. Atlantic coast. Floods are an ever-present problem, a problem which has become worse in recent decades. The relative sea level around Norfolk has risen 14.5 inches (.37 meter) since 1930, when the low-lying downtown area routinely flooded. The frequency of storms-induced surges has increased as well.

  • The impact of sea-level rise on coastal military installations

    The Pentagon says that climate-related effects are already being observed at Department of Defense (DoD) installations in every region of the United States and its coastal waters. The effects of climate change will adversely impact military readiness and DoD natural and built infrastructure unless these risks are considered in DoD decisions. A new white paper developed by the Pentagon’s Strategic Environmental Research and Development Program (SERDP) identifies key climate-related policy questions that need to be addressed.

  • Volcanic aerosols, not pollutants, slowed recent Earth warming

    Researchers looking for clues about why Earth did not warm as much as scientists expected between 2000 and 2010 now thinks the culprits are hiding in plain sight — dozens of volcanoes spewing sulfur dioxide.

  • RFI for cybersecurity framework for critical infrastructure

    In his 12 February 2013 Executive Order, President Obama called for the development of a Cybersecurity Framework to reduce cyber risks to critical infrastructure such as power plants and financial, transportation, and communications systems. The National Institute of Standards and Technology (NIST) the other day issued a Request for Information (RFI) in the Federal Register as its first step in the process to developing that framework.

  • No gloom-and-doom: science does not back global tipping point view

    A group of international ecological scientists have rejected a doomsday-like scenario of sudden, irreversible change to the Earth’s ecology. The scientists argue that global-scale ecological tipping points are unlikely and that ecological change over large areas seem to follow a more gradual, smooth pattern.

  • New power engineering curriculum to help U.S. security, economy

    Nearly 40 percent of all energy consumed in the United States is first converted to electricity, with that figure expected to rise to as much as 70 percent in the future. Increasing the pipeline of graduates in electric power and energy has implications for both the country’s place in the global market and national defense. The more expertise there is at home, the less the United States will have to import talent and energy resources from overseas. An Office of Naval Research (ONR)-supported project is bringing sweeping changes to electric power and energy education at universities throughout the country, establishing first-time programs at some schools and bringing new courses and labs to others.

  • Report details history, earlier versions of Stuxnet

    In 2010, Symantec reported on a new and highly sophisticated worm called Stuxnet. This worm became known as the first computer software threat which was used as a cyber-weapon. In a new report, Symantec says that clues in the code pointed to other versions of the worm which could potentially perform different actions leaving an open question about Stuxnet and how it came to be.
