• U.S. shale gas drives up coal exports – and CO2 emissions

    U.S. CO2 emissions from domestic energy have declined by 8.6 percent since a peak in 2005, the equivalent of 1.4 percent per year; researchers warn, however, that more than half of the recent emissions reductions in the power sector may be displaced overseas by the trade in coal

  • Making toilets out of waste plastic

    Washington Open Object Fabricators (WOOF) has won the 3D4D Challenge, and awarded a prize of $100,000 to help toward implementing the winning project – which will enable waste plastic to be used as filament for 3D printing machines, to create new products; the winning team plans to use the winning technology to address local issues in water and sanitation in Oaxaca, Mexico

  • Understanding the effects of Fukushima by studying fish

    Japan’s “triple disaster,” as it has become known, began on 11 March 2011, and remains unprecedented in its scope and complexity; to understand the lingering effects and potential public health implications of that chain of events, scientists are turning to a diverse and widespread sentinel in the world’s ocean: fish; the data from Japan fisheries provide a look at how the ocean is faring eighteen months after the worst accidental release of radiation to the ocean in history

  • Safety glass – cut to any shape

    If an object slams into the glass façade of a high-rise building, the glass must not shatter and fall down, because it could harm pedestrians below; in addition, the window panes must hold if a person were to fall against it from the inside; architects and builders must therefore use something stronger than laminated safety glass on the façades of high rise buildings; scientists develop a method which offers more flexibility with the design and handling of safety glass

  • Carbon-negative fuel at projected cost of less than $1.50 per gallon

    Cool Planet Energy Systems the other day announced a major breakthrough in the commercialization and affordability of biofuels from non-food biomass that can run in any vehicle on the road today; a successful field testing was conducted at Google Campus

  • Scientists improving process to recycle rare-earth materials

    Recycling keeps paper, plastics, and even jeans out of landfills. Could recycling rare-earth magnets do the same? Perhaps, if the recycling process can be improved; scientists are working more effectively to remove the neodymium, a rare earth element, from the mix of other materials in a magnet; initial results show recycled materials maintain the properties that make rare-earth magnets useful

  • Large-scale production of algae-based biofuels poses sustainability concerns

    Scaling up the production of biofuels made from algae to meet at least 5 percent — approximately thirty-nine billion liters — of U.S. transportation fuel needs would place unsustainable demands on energy, water, and nutrients, says a new report from the National Research Council; these concerns, however, are not a definitive barrier for future production, and innovations that would require research and development could help realize algal biofuels’ full potential

  • New biorenewables technology about to reach the marketplace

    Innovative technology provides a new way to transform cellulosic biomass into renewable fuels and high-value chemicals; ,the technology uses ionic liquids to break down cellulosic or non-food plant biomass without using enzymes or costly pretreatment steps

     

  • Kaspersky Lab working on a secure operating system for critical infrastructure

    Antivirus firmKaspersky Lab is set to make a major contribution to the security of critical infrastructure systems by developing an operating system specifically designed for such systems; the new operating system will protect information used in infrastructure such as nuclear power plants, transportation control facilities, gas and electrical systems,and other  facilities “criticallyimportant” to the economy and well-being of industrialized societies

  • Assessing bridge resilience

    Across the United States, more than 600,000 bridges link travelers to millions of roadway miles, forming a critical part of the nation’s infrastructure; because bridges are typically more vulnerable than roadways to damage caused by natural and man-made hazards, they are also of interest to DHS, which funds cutting-edge research in various aspects of structural integrity testing and blast-resistant structural design

  • Ideas from nature on how to convert solar into liquid fuel

    It has long been a dream of scientists to use solar energy to produce chemicals which could be stored and later used to create electricity or fuels; a recent scientific breakthrough is providing hope that this may soon be possible; the development would offer many benefits, including the ability to store chemicals until needed — current solar power technology has difficulties in this area

  • Analyzing the sound of rain falling on a bridge reveals bridge’s health, stability

    Engineers have found that by listening to how a highway bridge sings in the rain, they can determine serious flaws in the structure; employing a method called impact-echo testing, engineers can diagnose the health of a bridge’s deck based on the acoustic footprint produced by a little bit of water

  • Cybersecurity bill supporters want a vote on bill in this Congress

    Last week, lawmakers and top White House officials appeared in different events, conferences, and industry gatherings to promote the cyber security bill which has been stalled in the Senate since August; administration’s officials and lawmakers supporting the bill warned that the current situation leaves U.S. critical infrastructure and businesses vulnerable to attack from hackers and spies

  • Twenty-year anniversary of U.S. last full-scale nuclear test

    The first U.S. nuclear test, code named Trinity, took place in southern New Mexico forty-seven years earlier, on 16 July 1945; in all, the United States conducted 1,030 nuclear tests – the last one, code-named Divider,  took place twenty years ago, on 23 September 1992

  • Los Alamos lab accelerates shipment of nuclear waste to permanent storage site

    Los Alamos National Laboratory broke its own records in the first year of accelerated shipping effort of nuclear waste from the Lab to permanent disposal facilities located twenty-six miles outside of Carlsbad, New Mexico
