Loose grip
Carbon dioxide (CO2) is contained in the air we exhale, and is also always formed when carbon-containing substances such as oil, gas, wood, and plastics are burned - it is omnipres-ent. Chemists have long been trying to convert this gas to something useful, and Koji Tanaka and coworkers from the... view more (1999-01-28)

Reining in Energy Guzzlers
An ammonia catalyst for the next generation? Ammonia is of central importance to chemical industry and to society as a whole. It is the starting point for the generation of such diverse products as fertilizers, man-made fibers, dyes, and even pharmaceuticals, to name a few. However, the synthesis... view more (2001-03-09)

Nano-layer of ruthenium stabilizes magnetic sensors
A layer of ruthenium just a few atoms thick can be used to fine-tune the sensitivity and enhance the reliability of magnetic sensors, tests at the National Institute of Standards and Technology (NIST) show.   view more (2007-08-06)

Diamonds Are Forever Revealing New Insights into Earth's Development
Diamonds will take center stage this month in countless wedding ceremonies and other celebrations. In addition to their usual role as symbols of enduring love and fidelity, diamonds are now also helping geologists unravel clues about how the earth's precious metal mineralization was formed and why... view more (2008-06-13)

New catalysts may create more, cheaper hydrogen
A new class of catalysts created at the U.S. Department of Energy's Argonne National Laboratory may help scientists and engineers overcome some of the hurdles that have inhibited the production of hydrogen for use in fuel cells.   view more (2007-08-22)

Catalyst-free chemistry makes self-healing materials more practical
A new catalyst-free, self-healing material system developed by researchers at the University of Illinois offers a far less expensive and far more practical way to repair composite materials used in structural applications ranging from airplane fuselages to wind-farm propeller blades.   view more (2007-11-28)

Cornell researchers develop virus-size 'nanolamps' that could aid use of flexible electronic devices as sensors
To help light up the nanoworld, a Cornell interdisciplinary team of researchers has produced microscopic "nanolamps" — light-emitting nanofibers about the size of a virus or the tiniest of bacteria.   view more (2007-04-12)

Researchers think pink to produce 'green' solar energy
When it comes to producing earth-friendly solar energy, pink may be the new green, according to Ohio State University researchers. Scientists here have developed new dye-sensitized solar cells, that get their pink color from a mixture of red dye and white metal oxide powder in materials that... view more (2007-07-31)

Complex order parameter in ruthenate superconductors confirmed
Since it was discovered to be superconducting over a decade ago, the pairing symmetry of strontium ruthenium oxide has been widely explored and debated. Now, a team of researchers led by Dale Van Harlingen at the University of Illinois at Urbana-Champaign say the debate is over.   view more (2006-11-28)

Opening Atlantic Leaves Scots Isle Platinum Rich
The Platinum Group Elements (PGEs) are contained in mineral grains from the Rum Layered Intrusion, which represents the eroded roots of a once large volcano. They were formed deep in the crust as a plume of molten rock pushed up from deep within the Earth, causing huge volcanic eruptions, as well... view more (1999-02-08)

Protein transport in mitochondria revealed
The TIM23 complex, which regulates the transport of protein to the mitochondria in a cell, is much more complicated than was previously believed. This is shown by Uppsala University researcher Maria Lind in an article in the leading journal Cell.   view more (2005-03-31)

Study finds patients with complex fibroadenomas can avoid surgery
Complex fibroadenomas have a low incidence of malignancy, so women with this condition can be more conservatively treated and avoid surgical biopsy, according to a new study by a team of researchers from the Hadassah-Hebrew University Medical Center in Jerusalem.   view more (2008-02-12)

Current policy for complex surgery is misguided
Survival after complex surgery is better not only in hospitals that do a large volume of the same procedure, but also in hospitals that do a large volume of any complex procedure, finds new research. These findings challenge the policy that patients who need a high-risk procedure travel to... view more (2004-03-10)

Researcher discovers new materials
A research team led by Carnegie Mellon University Materials Science and Biomedical Engineering Professor Prashant Kumta has discovered a nanocrystalline material that is cheaper, more stable and produces a higher quality energy storage capacity for use in a variety of industrial and portable... view more (2006-07-11)

Bacteria in disguise cause problems for cystic fibrosis sufferers
Bacteria that cause infections in the lungs of cystic fibrosis patients avoid detection by changing their appearance according to Cardiff University researchers speaking today, Thursday 13 September 2001, at the bi-annual meeting of the Society for General Microbiology at the University of East... view more (2001-08-31)

Screening for complex genetic interactions
In a report published online ahead of the January 15th print edition, Dr. David Amberg (SUNY Upstate Medical University) and colleagues have developed a large-scale reverse genetic screen to identify complex haploinsufficient interactions in S. cerevisiae.   view more (2006-12-28)

Study questions 'cost of complexity' in evolution
Higher organisms do not have a "cost of complexity" - or slowdown in the evolution of complex traits - according to a report by researchers at Yale and Washington University in Nature.   view more (2008-04-01)

Too noisy to think: Workplaces that make women sick.
