Banded rocks reveal early Earth conditions, changes
The strikingly banded rocks scattered across the upper Midwest and elsewhere throughout the world are actually ambassadors from the past, offering clues to the environment of the early Earth more than 2 billion years ago. view more (2009-10-12)
Building blocks of the future
Structure and properties of carbon nanostructures The discovery in 1985 of fullerenes, tiny carbon balls of nanometer dimensions, ushered in a new era in international science. Only a few years later (1991) scientific interest also started to focus on so-called carbon nanotubes. The discovery of improved production methods (1996) has meanwhile... view more... (2002-12-05)
New 'control knobs' for stem cells identified
Natural changes in voltage that occur across the membrane of adult human stem cells are a powerful controlling factor in the process by which these stem cells differentiate, according to research published by Tufts University scientists. view more (2008-12-04)
UBC researchers develop breakthrough technique to unlock the secret of plasmas
University of British Columbia researchers have developed a technique that brings scientists a big step closer to unlocking the secrets of the most abundant form of matter in the universe. view more (2008-11-24)
Stressed seaweed contributes to cloudy coastal skies, study suggests
Scientists at The University of Manchester have helped to identify that the presence of large amounts of seaweed in coastal areas can influence the climate. view more (2008-05-07)
New imaging technique could promote early detection of multiple sclerosis
Researchers from Purdue University have studied and recorded how myelin degrades real-time in live mice using a new imaging technique. Myelin is the fatty sheath coating the axons, or nerve cells, that insulate and aid in efficient nerve fiber conduction. In diseases such as multiple sclerosis, the myelin sheath has been found to degrade. view more (2007-06-28)
Let water power your mobile phone: scientists discover new source of electricity
A new way of generating electricity from flowing water could mean that in the future you will never have to charge up your mobile phone again. Instead of a normal battery, mobile phones could be fitted with a battery that uses water - you just need to pressurise it regularly. This is the first new way of generating electricity discovered in over... view more... (2003-10-13)
The solution to a 7-decade mystery is crystal-clear to FSU chemist
A Florida State University researcher has helped solve a scientific mystery that stumped chemists for nearly seven decades. In so doing, his team's findings may lead to the development of more-powerful computer memories and lasers. view more (2007-10-22)
Chance encounter with comet nets surprising results
Comets are made of the most primitive stuff in the solar system. As hunks of rock and ice that never coalesced into more planets, they give researchers clues to the evolution of solar systems. view more (2007-10-02)
Einstein's tea leaves inspire new blood separation technique
Scientists at Monash University in Australia have developed a process for rapidly and efficiently separating blood plasma at the microscopic level without any moving parts, potentially allowing doctors to do blood tests without sending samples to a laboratory. view more (2007-01-18)
New approach to wound healing may be easy on skin, but hard on bacteria
In a presentation today (Aug. 19) to the American Chemical Society meeting, Ankit Agarwal, a postdoctoral researcher at the University of Wisconsin-Madison, described an experimental approach to wound healing that could take advantage of silver's anti-bacterial properties, while sidestepping the damage silver can cause to cells needed for healing. view more (2009-08-19)
Computer-designed molecule to clean up fluorocarbons?
The chemical bond between carbon and fluorine is one of the strongest in nature, and has been both a blessing and a curse in the complex history of fluorocarbons. Now, in a powerful demonstration of the relatively new field of "computational chemistry". view more (2007-03-05)
Peptide discovered in scorpion venom may hold key to secretory diseases
Researchers have discovered a peptide in scorpion venom that may hold the key to understanding and controlling cystic fibrosis and other secretory diseases. view more (2008-02-15)
A Supercharged Metal-Ion Generator
In the electronics industry, thin metal films are deposited on silicon wafers with a sputter gun, which uses energetic ions - atoms with a positive charge - to knock the metal atoms off a target. view more (2009-01-29)
'Peking Man' older than thought; somehow adapted to cold
A new dating method has found that "Peking Man" is around 200,000 years older than previously thought, suggesting he somehow adapted to the cold of a mild glacial period. view more (2009-03-13)
All-in-one nanoparticle: A Swiss Army knife for nanomedicine
Nanoparticles are being developed to perform a wide range of medical uses -- imaging tumors, carrying drugs, delivering pulses of heat. Rather than settling for just one of these, researchers at the University of Washington have combined two nanoparticles in one tiny package. view more (2009-07-28)
BBSRC announces its new ROPA awards
The Biotechnology and Biological Sciences Research Council (BBSRC) has announced its 1998 round of Realising Our Potential Awards (ROPAs). BBSRC is making 40 awards under the updated scheme in which awards can be made across all areas of research in each Research Council. The full list of BBSRC awards appears on pp10-11 of the current issue of... view more... (1998-10-12)
Researchers 'see' structure of open nicotinic acetylcholine ion channels
The neurotransmitter acetylcholine is an essential chemical communicator, carrying impulses from neurons to skeletal muscle cells and many parts of the nervous system. view more (2008-04-08)
UCR environmental scientists propose chemical solution to cleaning California's Salton Sea
UC Riverside scientists are able to improve water quality by 90 percent in the rivers flowing into the Salton Sea, the largest lake in California, by using two kinds of water-treatment chemicals that remove phosphorus and silt from the river water. view more (2005-11-04)
Orange juice is better than lemonade at keeping kidney stones away
A daily glass of orange juice can help prevent the recurrence of kidney stones better than other citrus fruit juices such as lemonade, researchers at UT Southwestern Medical Center have discovered. view more (2006-09-01)
