Movies of biological and chemical molecules made for first time

April 16, 2008
X-ray movie reveals movement of DNA molecule

Argonne National Laboratory scientists have developed accurate techniques for making movies of actual biological and chemical molecules for the first time.

Biological and organic molecules in solution are far more complex than the standard crystalline structures of salt or metals since they are constantly moving and changing over time.

Using the high-intensity X-rays at the Advanced Photon Source, the scientists have measured images that are blurred… read more

The impact of computer science on science as a whole was considered by a group of leading researchers, led by Stephen Emmott of Microsoft Research. Their report, “Towards 2020 Science,” is at research.microsoft.com.

Sifteo announces upcoming availability of Sifteo cubes

August 15, 2011

Sifteo Cubes

Sifteo Inc. has announced the upcoming availability of its Sifteo cubes to U.S. and Canadian customers.

Sifteo cubes are motion-aware 1.5-inch blocks with full-color screens that wirelessly connect with a personal computer during play to create unique interactions when shaken, tilted, rotated and neighbored next to one another.

Sifteo has also announced the availability of theĀ Sifteo Creativity Kit, which is included with… read more

UK to study nanotech benefits and risks

June 16, 2003

The UK Government has commissioned the Royal Society and the Royal Academy of Engineering to conduct an independent study to examine in detail the benefits and risks of nanotechnology.

The study will:

  • summarize the current scientific knowledge on nanotechnology;
  • identify applications of nanotechnology, both currently and potentially, with indications of when they might be developed;
  • consider environmental, health and safety, ethical and social

    Fighting Sleep: Researchers Reverse Cognitive Impairment Caused By Sleep Deprivation

    October 27, 2009

    A University of Pennsylvania research team has found a molecular pathway in the brain that is the cause of cognitive impairment due to sleep deprivation.

    The impairment may however be reversible by reducing the concentration of a specific enzyme that builds up in the hippocampus of the brain, they found.

    Second Family of High-Temperature Superconductors Discovered

    April 21, 2008
    (Kamihara et al.)

    Researchers in Japan and China have discovered a new family of iron-and-arsenic compounds that operate as high-temperature superconductors. Physicists are hailing the discovery as a major advance.

    Software Out There

    April 7, 2006

    Blocks of interchangeable software components are proliferating on the Web and developers are joining them together to create a potentially infinite array of useful new programs.

    This new software represents a marked departure from the inflexible, at times unwieldy, programs of the past, which were designed to run on individual computers.

    Laser Set Cells Aglow for Biopsy Without the Knife

    June 30, 2003

    A new laser-based method may enable pathologists to do instant biopsies of living tissue, speeding the process. Although the technique cannot yet see deep within tissue, it can provide images at a resolution of a single cell.

    The Cornell researchers create detailed biopsy images by scanning live tissue with a pulsed laser that focuses intense light on a tiny spot. Computer software then creates an image based on the… read more

    Singularity University Kicks Off First Executive Program

    November 6, 2009

    Singularity University (SU) will launch the SU Executive Program at the NASA Ames Research Center, Moffett Field, Calif. on Saturday.

    The nine-day program is designed to educate, inform and prepare executives for the imminent disruption and opportunities resulting from exponentially accelerating technologies.

    The SU Executive Program addresses six fields experiencing exponentially accelerating change: AI and Robotics, Nanotechnology, Biotechnology and Bioinformatics, Medicine and Human Machine Interface, Networks… read more

    Photoluminescence in nano-needles

    April 23, 2008

    Scientists at the University of California, Berkeley have grown gallium-arsenide structures into the shape of narrow needles which, when optically pumped, emit light with high brightness.

    In addition to optoelectronic devices, the needles could be valuable in such applications as atomic force microscopy (AFM), where the sharp tips can be grown in arrays without further etching or processing steps.

    Some believe that AFM arrays, besides speeding up the… read more

    Bio fuel cells could power portable gadgets

    April 23, 2006

    A hydrogen fuel cell that uses enzymes instead of expensive metal catalysts to drive chemical reactions has been developed by researchers from Oxford University.

    They used two enzymes, one harvested from bacteria and the other from fungus, to catalyse the same chemical reactions.

    A step toward a saliva test for cancer

    September 1, 2011

    A new saliva test developed by researchers at National Chung Cheng University (NCCU) in Taiwan that can measure the amount of potential carcinogens stuck to a person’s DNA was reported during the 242nd National Meeting & Exposition of the American Chemical Society (ACS) in Denver.

    “The test measures the amount of damaged DNA [DNA adducts] in a person’s body,”… read more

    Talking computers nearing reality

    July 10, 2003

    The technical kinks, high costs and application misfires that have held back the acceptance of speech recognition and activation are being ironed out.

    Digital ‘Cloud’ could form over London for the 2012 Olympics

    November 12, 2009

    digital-cloud-11-11-09

    MIT researchers have proposed to build a tourist attraction called “The Cloud” in London for the 2012 Olympics.

    The structure would consist of two 400-foot tall mesh towers that are linked by a series of interconnected plastic bubbles, which would themselves house an observation deck inside and be used to display everything from Olympic scores and highlights to a “barometer of the city’s interests and moods” outside.

    New nanotech products hitting the market at the rate of 3 to 4 per week

    April 25, 2008

    New nanotechnology consumer products are coming on the market at the rate of 3 to 4 per week, Project on Emerging Nanotechnologies (PEN) Project Director David Rejeski said in testimony before the Senate Commerce Committee Thursday.

    The number of consumer products using nanotechnology has grown from 212 to 609 since PEN launched the world’s first online inventory of manufacturer-identified nanotech goods in March 2006. Health and fitness items, which… read more
