Protons pair up with neutrons
Research performed at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility has found that protons are about 20 times more likely to pair up with neutrons than with other protons in the nucleus. view more (2008-05-30)
Antiprotons 4 times more effective than protons for cell irradiation
A pioneering experiment at CERN with potential future application in cancer therapy has produced its first results. Started in 2003, ACE (Antiproton Cell Experiment) is the first investigation of the biological effects of antiprotons. view more (2006-11-01)
Scientists discover that protons partner with neutrons more often than with other protons
Fast-moving protons are much more likely to pair up with fast-moving neutrons than with other protons in the nuclei of atoms, according to a recent experiment performed at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility. view more (2008-06-19)
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)
ESA's Cluster solved an auroral puzzle
ESA's four Cluster spacecraft have made a remarkable set of observations that has led to a breakthrough in understanding the origin of a peculiar and puzzling type of aurora. These aurorae - seen as bright spots in Earth's atmosphere and called 'dayside proton auroral spots' - occur when fractures appear in the Earth's magnetic field, allowing... view more... (2003-05-20)
Where is the proton? Yale scientists discover footprints of shared protons
This week in Science, Yale researchers present "roadmaps" showing that shared protons, a common loose link between two biological molecules, simply vibrate between the molecules as a local oscillator, rather than intimately entangling with the molecular vibrations of the attached molecules. view more (2007-04-13)
Observation of confinement phenomenon in condensed matter
An experiment has confirmed that spinons, particle-like magnetic excitations, can be confined in a magnetic insulator similar to the way elementary quarks are confined within individual protons and neutrons. view more (2009-11-30)
New technique helps researchers determine amino-acid charge
Measurements of the ion-current through the open state of a membrane-protein's ion channel have allowed scientists at the University of Illinois at Urbana-Champaign to obtain a detailed picture of the effect of the protein microenvironment on the affinity of ionizable amino-acid residues for protons. view more (2005-12-15)
NYU, Tel Aviv University create non-invasive imaging method for diagnosing osteoarthritis
Researchers at New York University and Tel Aviv University have developed a non-invasive imaging method that can be used to diagnose and monitor a number of diseases, including osteoarthritis and inter-vertebral disc degeneration, in their early stages. view more (2008-02-12)
U-M physicists' analysis leads to discovery of new particle
University of Michigan physicists played a leading role in the discovery of a new particle, the Omega b baryon, which is an exotic relative of the proton. view more (2008-09-11)
How the Moon produces its own water
The Moon is a big sponge that absorbs electrically charged particles given out by the Sun. These particles interact with the oxygen present in some dust grains on the lunar surface, producing water. view more (2009-10-15)
Nuclear physicists examine oxygen's limits
Physicists at the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University have made a unique measurement of an exotic oxygen nucleus, leading scientists one step closer to deciphering the behavior of the element at its limits of existence. view more (2007-09-14)
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)
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)
Nature Points the way to a sustainable hydrogen economy
"This is an exciting early step in developing a sustainable system for producing electricity from hydrogen" said Professor Chris Pickett (Associate Head of the Biological Chemistry Department at JIC). "In Nature iron-sulphur enzymes catalyse a range of important chemical reactions that industry can only do by using precious metal... view more... (2005-02-10)
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)
'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)
The first results of Finuda will be announced on January 30th: a new window for the study of exotic atomic nuclei.
On Friday the 30th, during the XLII international winter meeting on nuclear physics at Bormio, the first results will be announced of Finuda experiment (Nuclear Physics at Daphne), settled in Frascati at Infn National Laboratories. Planned and made operating by a group of about forty physicists from Universities and Infn Sites of Bari, Brescia,... view more... (2004-01-29)
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)
