• Scientists: Deepwater Horizon exposed gaps in deepwater oil spill knowledge

    On the second anniversary of the Deepwater Horizon oil spill in the Gulf of Mexico, a national team of scientists warns that inadequate knowledge about the effects of deepwater oil well blowouts threatens scientists’ ability to help manage comparable future events

  • Solar storms and infrastructure vulnerabilities

    Space weather, and in particular coronal mass ejections, can cause huge disruption to many highly technological systems on Earth; experts say that vulnerable industries, such as power grids and airlines, should gather more information on space weather in order to make more informed decisions about how to deal with future solar storms

  • Efficiency of multi-hop wireless networks boosted

    Multi-hop wireless networks can provide data access for large and unconventional spaces, but they have long faced significant limits on the amount of data they can transmit; now researchers have developed a more efficient data transmission approach that can boost the amount of data the networks can transmit by 20 to 80 percent

  • Honda to reuse rare Earth metals from used parts

    Rare Earth elements are essential to advanced technological application and to green technology products; China controls 97 percent of the world’s production of these elements, and has been using its near-monopoly to hobble non-Chinese companies and for political blackmail; in response, two Japanese companies announce a new process allowing them to extract as much as 80 percent or more of rare Earth metals contained in used nickel-metal hydride batteries

  • Himalayan glaciers decline less rapidly than previously feared

    Several hundreds of millions of people in Southeast Asia depend, to varying degrees, on the freshwater reservoirs of the Himalayan glaciers; it is thus important to detect the potential impact of climate changes on the Himalayan glaciers at an early stage; together with international researchers, glaciologists from the University of Zurich now show that the glaciers in the Himalayas are declining less rapidly than was previously thought; the scientists, however, see major hazard potential from outbursts of glacial lakes

  • Autonomous, self-replicating robots for finding extraterrestrials

    Autonomous, self-replicating robots — exobots — are the way to explore the universe, find and identify extraterrestrial life, and perhaps clean up space debris in the process; scientists note that if aliens are out there, they have the same problems we do: they need to conserve resources, are limited by the laws of physics, and they may not even be eager to meet us

  • Cellphones could soon see through walls

    Researchers have designed an imager chip that could turn mobile phones into devices that can see through walls, wood, plastics, paper, and other objects; the chip exploits the terahertz band of the electromagnetic spectrum, which is one of the wavelength ranges that falls between microwave and infrared, and which has not been accessible for most consumer devices

  • Bridges get a quick check-up with new imaging technique

    EPFL engineers have developed a new imaging technique which allows engineers  to see the insides of massive concrete bridges; much like a sonogram, this technique provides quick, easy-to-interpret images, so that the health of these expensive structures can be assessed and monitored

  • California quake test shows promise of new building code

    Researchers place a model hospital on a shake table to assess the structure’s ability to withstand earthquake; in accordance with California latest building code, base isolators, which are rubber bearings intended to absorb the shock of the motion, were installed underneath the structure; the hospital passed the 6.7-magnitude and 8.8-magnitude tests with flying colors

  • Water vulnerability in U.S. border region

    The Arizona-Sonora region has been called the front line of ongoing climate change, with global climate models projecting severe precipitation decreases and temperature increases coupled with vulnerability from urbanization, industrialization and agricultural intensification

  • Robust nanosponges soak up oil again and again

    Researchers show that nanotube blocks hold promise for environmental cleanup following oil spills or other disasters; the robust sponge can be used repeatedly and stands up to abuse; a sample nanosponge remained elastic after about 10,000 compressions in the lab; the sponge can also store the oil for later retrieval

  • Insider: H5N1 studies publication vote biased, unbalanced

    In late March, the National Science Advisory Board for Biosecurity (NSABB) reversed its earlier recommendation, made in December 2011, against full publication of two studies describing lab-modified H5N1 viruses with increased transmissibility in mammals; the recommendation was based on fears that the findings would help terrorist design effective bioweapons; a NSABB board member says that the March reversal of the December recommendation was the result of a bias toward finding a solution that was more about getting the government out of the current dilemma than about a careful risk-benefit analysis

  • Ion stream to clean up Earth orbit, deflect asteroids

    One of the legacies of the space age is an ever-more-crowded near-Earth orbit, where all manner of long-abandoned human-made objects loiter, posing danger to newer space platforms; scientists want to develop a magnetized-beam plasma propulsion device which would be deployed in Earth orbit and which would  use a focused ion stream to push dead satellites and other debris toward Earth’s atmosphere, where they would mostly burn up on re-entry; the device could also be used to deflect menacing Earth-bound asteroids hurtling toward Earth

  • Diet change required to curb most potent greenhouse gas

    N2O is the third highest contributor to climate change behind carbon dioxide (CO2) and methane (CH4), but it poses a greater challenge to mitigate as nitrogen is an essential element for food production; it is also the most potent of these three greenhouse gases as it is a much better absorber of infrared radiation

  • Rhinoceros beetles foretell future of flapping-wing design

    Researchers launch a quantitative investigation of aerodynamics and wing kinematics in rhinoceros beetle flight in order to shed new light on the evolution of flapping flight in nature; experimental study of the aerodynamic performance of beetles in forward/hovering flight will provide insight into designs for efficient and stable flapping-wing micro aerial vehicles
