Climate scientists compute in concert - 0 views

  •  
    Researchers at Oak Ridge National Laboratory (ORNL) are sharing computational resources and expertise to improve the detail and performance of a scientific application code that is the product of one of the world's largest collaborations of climate researchers. The Community Earth System Model (CESM) is a mega-model that couples components of atmosphere, land, ocean, and ice to reflect their complex interactions. By continuing to improve science representations and numerical methods in simulations, and exploiting modern computer architectures, researchers expect to further improve the CESM's accuracy in predicting climate changes. Achieving that goal requires teamwork and coordination rarely seen outside a symphony orchestra.

How Smartphones Can Improve Public Transit | Autopia | Wired.com - 1 views

  •  
    Smartphone apps may be the key to getting people out of their cars and onto mass transit. An interesting study of commuters in Boston and San Francisco found people are more willing to ride the bus or train when they have tools to manage their commutes effectively. The study asked 18 people to surrender their cars for one week. The participants found that any autonomy lost by handing over their keys could be regained through apps providing real-time information about transit schedules, delays and shops and services along the routes. Though the sample size is small, the researchers dug deep into participants' reactions. The results could have a dramatic effect on public transportation planning, and certainly will catch the attention of planners and programmers alike. By encouraging the development of apps that make commuting easier, transit agencies can drastically, and at little cost, improve the ridership experience and make riding mass transit more attractive.

Largest bird alters its foraging due to climate change - 0 views

  •  
    Wandering albatrosses have altered their foraging due to changes in wind fields in the southern hemisphere during the last decades. Since winds have increased in intensity and moved to the south, the flight speed of albatrosses increased and they spend less time foraging. As a consequence, breeding success has improved and birds have gained 1 kilogram. These are the results of the study of an international research team published in the latest issue of the Science journal. However, these positive consequences of climate change may last short if future wind fields follow predictions of climate change scenarios, researchers warn.

Opening Gambit: Best. Decade. Ever. - By Charles Kenny | Foreign Policy - 0 views

  •  
    On the other hand, humanity's malignant effect on the environment has accelerated the rate of extinction for plants and animals, which now reaches perhaps 50,000 species a year. But even here there was some good news. We reversed our first man-made global atmospheric crisis by banning chlorofluorocarbons -- by 2015, the Antarctic ozone hole will have shrunk by nearly 400,000 square miles. Stopping climate change has been a slower process. Nonetheless, in 2008, the G-8 did commit to halving carbon emissions by 2050. And a range of technological advances -- from hydrogen fuel cells to compact fluorescent bulbs -- suggests that a low-carbon future need not require surrendering a high quality of life. Technology has done more than improve energy efficiency. Today, there are more than 4 billion mobile-phone subscribers, compared with only 750 million at the decade's start. Cell phones are being used to provide financial services in the Philippines, monitor real-time commodity futures prices in Vietnam, and teach literacy in Niger. And streaming video means that fans can watch cricket even in benighted countries that don't broadcast it -- or upload citizen reports from security crackdowns in Tehran. Perhaps technology also helps account for the striking disconnect between the reality of worldwide progress and the perception of global decline. We're more able than ever to witness the tragedy of millions of our fellow humans on television or online. And, rightly so, we're more outraged than ever that suffering continues in a world of such technological wonder and economic plenty. Nonetheless, if you had to choose a decade in history in which to be alive, the first of the 21st century would undoubtedly be it. More people lived lives of greater freedom, security, longevity, and wealth than ever before. And now, billions of them can tweet the good news. Bring on the 'Teenies.

Progress in the development of rechargeable batteries through nanotechnology - 0 views

  •  
    Researchers are testing different ways of improving rechargeable batteries for electric vehicles and nanotechnology plays an important role in the development. The aim is to offer batteries that have fast charge and discharge rates as well as high stored energy per mass. This can make electric vehicles a competitive alternative to petrol-powered vehicles.

Measuring the next generation of life-saving pollution sensors - 0 views

  •  
    ew research from the UK's National Physical Laboratory (NPL) is helping Duvas Technologies Ltd (Duvas) to develop improved air quality monitoring instrumentation. Currently over 1bn people a year suffer from respiratory disease associated with pollution, and according to the World Health Organisation, over 3m a year die from its effects. Duvas is planning to help provide technology to understand and address this problem.

Will we hear the light? Surprising discovery that infrared can activate heart and ear c... - 0 views

  •  
    University of Utah scientists used invisible infrared light to make rat heart cells contract and toadfish inner-ear cells send signals to the brain. The discovery someday might improve cochlear implants for deafness and lead to devices to restore vision, maintain balance and treat movement disorders like Parkinson's

Your Next Computer May Be Made of...Blood! - 0 views

  •  
    We're stumbling through a science fiction wonderland of not just high-flying communications software and tools but of the basic building blocks for the devices we use to do that communicating. The latest contender for radically-improved memory in a computer? Blood. Researchers in Gujarat, India have created a "memristor" -- a portmanteau of memory and resistor -- made of human blood. A resistor is the part of a computer chip that regulates the flow of electricity. Unlike most resistors, a memristor remembers previous levels of voltage and allows for a repeat of that flow.

It Works: Taking Cars Out of Times Square Really Improved the Air - Culture - GOOD - 0 views

  •  
    Back in 2009 Mayor Bloomberg prohibited vehicle traffic on Broadway between 42nd Street and 47th Street in Times Square to create a pedestrian plaza (video here). Now, the city's most recent Community Air Survey found that, "After the conversion to a pedestrian plaza, NO pollution levels in Times Square went down by 63 percent while, NO2 levels went down by 41 percent." Unlike N2O, which makes you laugh at Phish shows, NO2, or nitrogen dioxide, destroys your lungs and may cause Sudden Infant Death Syndrome. Nitric oxide (NO) isn't good for you either.

Global forestry institutions call for more community-based forest management - 0 views

  •  
    The leading international organizations working to protect and manage the world's forests are calling for governments across the globe to increase communities' role in forest management. Doing so could contribute to lifting close to a billion people out of poverty, as well as improve the health and vitality of forests.

NIST prototypes framework for evaluating sustainability standards - 0 views

  •  
    As manufacturers and other businesses step up efforts to cut waste, reduce energy use and improve the overall sustainability of their products and processes, the number of planet-friendly standards and regulations also is increasing at a rapid clip, creating a sometimes-confusing array of options for "going green." National Institute of Standards and Technology (NIST) researchers have prototyped a framework to help organizations of all types sort through the welter of choices and evaluate and implement sustainability standards most appropriate for their operations and interests.

Solar power goes viral: Modified virus improves solar-cell efficiency by one-third - 0 views

  •  
    In a solar cell, sunlight hits a light-harvesting material, causing it to release electrons that can be harnessed to produce an electric current. The new MIT research, published online this week in the journal Nature Nanotechnology, is based on findings that carbon nanotubes - microscopic, hollow cylinders of pure carbon - can enhance the efficiency of electron collection from a solar cell's surface.
