2-proton Bit Controlled By Single Copper Atom
2014-01-17 12:27:57

Institute of Physical Chemistry of the Polish Academy of Sciences Just a single foreign atom located in the vicinity of a molecule can change spatial arrangement of its atoms. In a spectacular experiment, an international team of researchers was able to change persistently positions of the nuclei of hydrogen atoms in a porphycene molecule by approaching a single copper atom to the molecule. A subatomic bit formed by two protons tunneling inside a simple organic molecule can be switched...

Researchers have made the first experimental determination of the weak charge of the proton in research carried out at the Department of Energy's Thomas Jefferson National Accelerator Facility (Jefferson Lab). The results, accepted for publication in Physical Review Letters, also include the determinations of the weak charge of the neutron, and of the up quark and down quark. These determinations were made by combining the new data with published data from other experiments. Although these...

H2O Reveals New Secret

Carnegie Institution Using revolutionary new techniques, a team led by Carnegie's Malcolm Guthrie has made a striking discovery about how ice behaves under pressure, changing ideas that date back almost 50 years. Their findings could alter our understanding of how the water molecule responds to conditions found deep within planets and could have implications for energy science. Their work is published in the Proceedings of the National Academy of Sciences. When water freezes into ice,...

Dense Matter Of Neutron Stars Revealed Through X-Ray Observations
2013-03-07 12:03:35

April Flowers for redOrbit.com - Your Universe Online The densest matter in the Universe outside of black holes is contained in neutron stars, the ultra-dense cores left behind after massive stars collapse. One of the most reliable determinations yet of the relationship between the radius of a neutron star and its mass has been provided by new results from NASA's Chandra, along with European Space Agency's (ESA) XMM-Newton and NASA's Rossi X-ray Timing Explorer (RXTE), which constrain how...

New Technique Could Reveal High Detail Of Earth's Composition
2013-02-22 10:50:16

April Flowers for redOrbit.com - Your Universe Online In a new study recently published in the journal Science, a research team from Amherst College and The University of Texas at Austin has described a new technique that might one day reveal the composition and characteristics of the deep Earth in never before seen detail. There's just a tiny little hitch in the new technique. It relies on a fifth force of nature that has not yet been detected. Current physics theories hold that there...

Proton May Have Lost Weight
2013-01-25 08:27:16

April Flowers for redOrbit.com - Your Universe Online A new study, released this week in the journal Science, shows that even in the world of sub-atomic particles, size matters. An international group of scientists led by Aldo Antognini, a physicist at the Max Planck Institute for Quantum Optics, say the proton, a basic building block of all matter, appears to be smaller than previously thought. This finding, which confirms a similar result the team showed in 2010, may open new...

Structure Of Carbon’s ‘Hoyle State’ Revealed By Researchers
2012-12-10 21:12:05

North Carolina State University A North Carolina State University researcher has taken a “snapshot” of the way particles combine to form carbon-12, the element that makes all life on Earth possible.  And the picture looks like a bent arm. Carbon-12 can only exist when three alpha particles, or helium-4 nuclei, combine in a very specific way. This combination is known as the Hoyle state. NC State physicist Dean Lee and German colleagues Evgeny Epelbaum, Hermann Krebs and...

For the first time, researchers have confirmed the existence of antimatter in the Earth's magnetosphere, BBC News reported on Sunday. Writing in Astrophysical Journal Letters, the researchers report that they discovered a thin band of antiprotons lying in between the inner and outer Van Allen radiation belts using the PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics) satellite. Though the British news organization claims that only a small number of antiprotons...

Physicists at the U.S.-based Fermilab have produced a new particle that is a heavier relative of the neutron. The Batavia, Illinois atom smasher found the neutral Xi-sub-b by smashing particles together around a 4-mile ring at near light speed.  Physicists knew the particle existed, but it is the first time researchers have observed it firsthand.  Measuring the properties of particles like the neutral Xi-sub-b allows physicists to understand how quarks interact to form matter....

Most important milestone in the direct measurement of the magnetic moment of the proton and its anti-particle has been achieved / Focusing the matter-antimatter symmetry Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM), together with their colleagues from the Max Planck Institute for Nuclear Physics in Heidelberg and the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, have observed spin quantum-jumps with a single trapped proton for...
