• The infrastructure of asteroid-mining economy

    An asteroid-mining space economy would be easier to build if there were the equivalent of a few Stuckey’s around out there. As is the case with other enterprises, a space economy will need fuel, liquids, and supplies, and these could be stored in outposts on dwarf planets like Ceres.

  • 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.

  • New radioactive waste repackaging facility in Los Alamos

    The Los Alamos National Laboratory has brought a third waste repackaging facility online to increase its capability to process nuclear waste for permanent disposal. The box line facility is largest of its kind ever built.

  • 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. 

  • Grid-scale batteries for storing renewable energy have large carbon footprint

    Most of the electricity produced in the United States comes from coal- and natural gas-fired power plants. Only about 3 percent is generated from wind, solar, hydroelectric, and other renewable sources.  A key problem is that the U.S. electrical grid has virtually no storage capacity, so grid operators cannot stockpile surplus clean energy and deliver it at night, or when the wind is not blowing. Stanford scientists have developed a novel way to calculate the energetic cost of building large batteries and other storage technologies for the electrical grid. The found that the fossil fuel required to build these technologies could negate some of the environmental benefits of installing new solar and wind farms.

  • New trends in cybersecurity and information security education

    The Federal Information Systems Security Educators’ Association (FISSEA)promotes cybersecurity awareness, training, and education. The annual meeting,to be held 19-21 March 2013 at NIST headquartersin Gaithersburg, Maryland, is geared toward both new and seasoned security officers, IT managers, information security educators and researchers, cybersecurity trainers and teachers, and those involved in instructional design and curriculum development.

  • How to predict the progress of technology

    MIT researcher finds Moore’s Law and Wright’s Law best predict how technology improves.

  • 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.

  • Coal and U.S electric power generation

    Coal is an important fuel source in the United States today. Responsible for approximately 39 percent of the country’s electrical generation, coal is vital to the day-to-day operation of people’s lives. The United States is rich in coal deposits, with large resources.  One of the most important and largest of those deposits is found in the Powder River Basin (PRB) of Wyoming and Montana, which, in 2012, produced more than 42 percent of the nation’s coal.

  • Stopping vehicle in their tracks -- remotely

    The need to stop vehicles remotely was identified by the law enforcement community. In 2010, the characteristics of a squid’s sticky tendrils were combined with the concept of Spiderman’s super-strong webbing to create a prototype of the first remote device to stop vehicles in their tracks: the Safe, Quick, Undercarriage Immobilization Device (SQUID).

  • Arctic ice loss intensified Superstorm Sandy ferocity

    If you believe that last October’s Superstorm Sandy was a freak of nature — the confluence of unusual meteorological, atmospheric and celestial events – then Cornell and Rutgers researchers suggest you should think again. The researchers report that the severe loss of summertime Arctic sea ice — attributed to greenhouse warming — appears to enhance Northern Hemisphere jet stream meandering, intensify Arctic air mass invasions toward middle latitudes, and increase the frequency of atmospheric blocking events like the one that steered Hurricane Sandy west into the densely populated New York City area.

  • 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.

  • Using plants for herbal defluoridation of drinking water

    A filtration system based on a medicinal herb can quickly and easily remove “fluoride” from drinking water, say researchers in India. The technology uses parts of the plant Tridax procumbens as a biocarbon filter for the ion.

  • World’s first zero emission sports car is built-at-home electric car

    A new partnership has developed the world’s first build at home electric race car kit, an all-electric sports car designed and engineered to support a growing demand for zero emission racing vehicles. The iRacer kit, available from £13,999, can be transformed quickly between hybrid, pure electric, or internal combustion engines.
