Climate change and the rise of atmospheric oxygen
Today's climate change pales in comparison with what happened as Earth gave birth to its oxygen-containing atmosphere billions of years ago. view more (2006-03-23)
Robotic assembly of fuel cells could hasten hydrogen economy
"The U.S. Department of Energy has suggested that the cost of manufacturing fuel cells is the single biggest obstacle on the road to the hydrogen economy," says Raymond Puffer, co-director of the FMC. view more (2005-11-09)
Scientists capture the speediest ever motion in a molecule
The fastest ever observations of protons moving within a molecule open a new window on fundamental processes in chemistry and biology, researchers report today in the journal Science. view more (2006-03-03)
Non-invasive MRI technique distinguishes between Alzheimer's and frontotemporal dementia
A non-invasive magnetic resonance imaging (MRI) technique called arterial spin labeling is just as accurate as invasive scanning techniques in distinguishing Alzheimer's disease from frontotemporal dementia (FTD) in the brains of elderly people, according to a new study at the San Francisco VA Medical Center (SFVAMC). view more (2005-06-20)
Chemical Could Revolutionize Polymer Fuel Cells
Heat has always been a problem for fuel cells. There's usually either too much (ceramic fuel cells) for certain portable uses, such as automobiles or electronics, or too little (polymer fuel cells) to be efficient. view more (2005-08-25)
Hi ho silver! FSU physicist helps discover an atomic oddity
Working with an international team of scientists, a Florida State University physics professor has taken part in an experiment that resulted in the creation of a silver atom with exotic properties never before observed. view more (2006-01-30)
First beam for Large Hadron Collider, world's mightiest particle accelerator
An international collaboration of scientists today sent the first beam of protons zooming at nearly the speed of light around the 17-mile-long underground circular path of the Large Hadron Collider (LHC), the world's most powerful particle accelerator, located at the CERN laboratory near Geneva, Switzerland. view more (2008-09-11)
'Pinball protons' created by ultraviolet rays and other causes can lead to DNA damage
Researchers have known for years that damaged DNA can lead to human diseases such as cancer, but how damage occurs-and what causes it-has remained less clear. view more (2006-05-18)
UCR-led research team detects 'top quark,' a basic constituent of matter
A group of 50 international physicists, led by UC Riverside's Ann Heinson, has detected for the first time a subatomic particle, the top quark, produced without the simultaneous production of its antimatter partner - an extremely rare event. view more (2006-12-14)
A Theoretical Breakthrough Inspired by Experiment-Calculating Electron Correlations in the Hydrogen Molecule
Need to understand the details of how a molecule is put together? Want to see the effects of the intricate dance that its electrons do to make a chemical bond? Try blowing a molecule to bits and calculating what happens to all the pieces. view more (2005-12-16)
Targeted drug delivery now possible with 'pHLIP' peptide
Scientists at Yale and the University of Rhode Island report the development of a peptide that can specifically and directly deliver molecules to the inside of cells like a nanosyringe, creating a new tool for drug delivery, gene control and imaging of diseased tissues. view more (2006-04-12)
Mars Express discovers aurorae on Mars
ESA's Mars Express spacecraft has for the first time ever detected an aurora on Mars. This aurora is of a type never previously observed in the Solar System. view more (2005-06-10)
A new particle discovered by BaBar experiment
Its name is Y(4260) and it is not a new humanoid of Stars Wars, but a particle identified for the first time by BaBar experiment: an international collaboration-formed by the large participation of the Italian physicists of the National Institute for Nuclear Physics (Infn)-that has its seat in Stanford (California). Y(4260) represents an... view more... (2005-07-07)
Supercomputers help physicists understand a force of nature
What if the tiniest components of matter were somehow different from the way they exist now, perhaps only slightly different or maybe a lot? What if they had been different from the moment the universe began in the big bang? Would matter as we know it be the same? Would humans even exist? view more (2006-07-12)
G-Zero update
In research performed in Hall C, nuclear physicists have found that strange quarks do contribute to the structure of the proton. This result indicates that, just as previous experiments have hinted, strange quarks in the proton's quark-gluon sea contribute to a proton's properties. The result comes from work performed by the G-Zero collaboration,... view more... (2006-06-30)
Identifying the 'signatures' of protons in water
Free protons from acids associate with 1, 2 or 3 molecules of water and the structures can be identified by unique infrared laser spectrum signatures, according to a report in Science by Yale professor of chemistry Mark A. Johnson and his collaborators at Yale, the University of Pittsburgh and the University of Georgia. view more (2005-07-14)
Direct photon properties reveal secrets of extreme nuclear states
When atomic nuclei are smashed together at great speed, resulting temperatures exceed one trillion degrees, 200 million times hotter than the surface of the sun. view more (2006-04-26)
Nature's process for nitrogen fixation caught in action
Nitrogen gas is converted to ammonia fertilizer by a chemical process that involves high temperature and high pressure. Nature does the same thing at ambient temperature and pressure. The process, called nitrogen fixation, is essential to life as it provides nutrients to plant life. view more (2006-11-10)
G-Zero Finds that Ghostly Strange Quarks Influence Proton Structure
In research performed at the Department of Energy's Jefferson Lab, nuclear physicists have found that strange quarks do contribute to the structure of the proton. This result indicates that, just as previous experiments have hinted, strange quarks in the proton's quark-gluon sea contribute to a proton's properties. view more (2005-06-20)
Cholera pathogen reveals how bacteria generate energy to live
Researchers at Rensselaer Polytechnic Institute have discovered new details about how bacteria generate energy to live. In two recently published papers, the scientists add key specifics to the molecular mechanism behind the pathogen that causes cholera. view more (2007-01-30)
