Physicists at the National Institute of Standards and Technology (NIST) have demonstrated entanglement—a phenomenon peculiar to the atomic-scale quantum world—in a mechanical system similar to those in the macroscopic everyday world. The work extends the boundaries of the arena where quantum behavior can be observed and shows how laboratory technology might be scaled up to build a functional quantum computer.
New York/London/Nairobi, 3 June 2009 -- Some $155 billion was invested in 2008 in clean energy companies and projects worldwide, not including large hydro, a new report launched today says.
Of this $13.5 billion of new private investment went into companies developing and scaling-up new technologies alongside $117 billion of investment in renewable energy projects from geothermal and wind to solar and biofuels.
DALLAS – June 3, 2009 – A simple magnetic resonance imaging (MRI) test involving breathing oxygen might help oncologists determine the best treatment for some cancer patients, report researchers at UT Southwestern Medical Center.
The secret of a successful sandcastle could aid the revival of an ancient eco-friendly building technique, according to research led by Durham University.
Researchers, led by experts at Durham's School of Engineering, have carried out a study into the strength of rammed earth, which is growing in popularity as a sustainable building method.
Just as a sandcastle needs a little water to stand up, the Durham engineers found that the strength of rammed earth was heavily dependent on its water content.
Electronic memory chips may soon gain the ability to bend and twist as a result of work by engineers at the National Institute of Standards and Technology (NIST). As reported in the July 2009 issue of IEEE Electron Device Letters,* the engineers have found a way to build a flexible memory component out of inexpensive, readily available materials.
PROVIDENCE, R.I. [Brown University] — Actinic keratoses are sun-damaged rough patches or lesions on the skin — often pink and scaly — that doctors have long believed can turn into a form of skin cancer known as squamous cell carcinoma.
Now researchers at Brown University, the Veterans Administration Medical Centers in Providence and Oklahoma City, and others have determined that actinic keratoses appear responsible for a larger spectrum of skin cancers than previously thought. Their research is highlighted in the current edition of Cancer.
Approximately a third of the electricity consumed by large data centers doesn't power the computer servers that conduct online transactions, serve Web pages or store information. Instead, that electricity must be used for cooling the servers, a demand that continues to increase as computer processing power grows.
And the trend toward cloud computing will expand the need for both servers and cooling.
In these times of trillion-dollar budgets and deficits, $6.3 billion may not seem like much money, but that's what the United States potentially could save on each group of adolescents who enter foster care every year.
These savings could be achieved by using a more intensive and more costly private model of foster care than programs offered by public agencies across the country, according to new research led by economists and foster care experts from the University of Washington and Casey Family Programs, a non-profit agency with offices in Washington and Oregon.
Penguin poo (guano) stains, visible from space, have helped British scientists locate emperor penguin breeding colonies in Antarctica. Knowing their location provides a baseline for monitoring their response to environmental change.
CAMBRIDGE, Mass., June 2, 2009 -- New research shows some bees brace themselves against wind and turbulence by extending their sturdy hind legs while flying. But this approach comes at a steep cost, increasing aerodynamic drag and the power required for flight by roughly 30 percent, and cutting into the bees' flight performance.
The findings are detailed in the Proceedings of the National Academy of Sciences.
