Etched quantum dots shape up as single photon emitters (February 26, 2011) -- Like snowflakes or fingerprints, no two quantum dots are identical. But a new etching method for shaping and positioning these semiconductor nanocrystals might change that. Tests confirm that etched quantum dots emit single particles of light, boosting prospects for powering new types of devices for quantum communications. ... > full story
Atomic antennas transmit quantum information across a microchip (February 26, 2011) -- New research suggests a fundamentally novel architecture for quantum computation. They have experimentally demonstrated quantum antennas, which enable the exchange of quantum information between two separate memory cells located on a computer chip. This offers new opportunities to build practical quantum computers. ... > full story
Nanotechnology may lead to new treatment of liver cancer (February 26, 2011) -- Nanotechnology may open a new door on the treatment of liver cancer, according to researchers. They used molecular-sized bubbles filled with chemotherapy drugs to prevent cell growth and initiate cell death in test tubes and mice. ... > full story
New way to design metal nanoparticle catalysts (February 26, 2011) -- Researchers have discovered a new strategy for fabricating metal nanoparticles in catalysts that promises to enhance the selectivity and yield for a wide range of structure-sensitive catalytic reactions. ... > full story
New form of sulfur discovered in geological fluids (February 25, 2011) -- Sulfur is the sixth most abundant element on Earth and plays a key role in many geological and biological processes. Scientist have now identified a novel form of sulfur present in geological fluids: the S3(-) ion. The discovery calls existing theories about the geological transport of sulfur into question, and could provide ways of identifying new deposits of precious metals such as gold and copper. ... > full story
Simpler way of making proteins could lead to new nanomedicine agents (February 25, 2011) -- Researchers have developed a simple method of making short protein chains with spiral structures that can also dissolve in water, two desirable traits not often found together. The researchers observed that as they increased the length of the side chains with charges on the end, the polypeptides' propensity for forming helices also increased. Such structures could have applications as building blocks for self-assembling nanostructures and as agents for drug and gene delivery. ... > full story
Redesign of US donor-liver network could boost transplants by several hundred per year (February 25, 2011) -- Researchers redesigned the U.S.'s haphazard donor-liver distribution network to better account for urban and rural population differences, geographic distance, and the anticipated supply of and demand for donor livers. They calculated a rearrangement could result in up to 14 percent more people each year receiving the transplants they need. ... > full story
Solar experts detect waves in giant magnetic holes the size of the UK (February 25, 2011) -- Massive waves in giant magnetic holes on the surface of the Sun have been discovered for the first time by solar scientists, something that will bring experts a step closer to unlocking the secrets of the Sun. ... > full story
Gas rich galaxies confirm prediction of modified gravity theory (February 25, 2011) -- Recent data for gas rich galaxies precisely match predictions of a modified theory of gravity know as MOND according to a new analysis. ... > full story
Producing clean water in an emergency (February 25, 2011) -- Chemistry researchers have taken a key step towards making a cheap, portable, paper-based filter coated with silver nanoparticles to be used in emergency situations like floods, tsunamis or earthquakes. ... > full story
Migrating cells flow like glass: Research advances understanding of wound healing, cancer metastasis, and embryonic development (February 25, 2011) -- By studying cellular movements at the level of both the individual cell and the collective group, applied physicists have discovered that migrating tissues flow very much like colloidal glass. ... > full story
Catalogue of sustainable design resources developed (February 25, 2011) -- A new catalog of eco-friendly materials for use in the construction industry has been developed. ... > full story
