Physicists create millimeter-sized 'Bohr atom'
Nearly a century after Danish physicist Niels Bohr offered his planet-like model of the hydrogen atom, a Rice University-led team of physicists has created giant, millimeter-sized atoms that resemble it more closely than any other experimental realization yet achieved. view more (2008-07-01)
Molecular spintronic action confirmed in nanostructure
Researchers at the National Institute of Standards and Technology (NIST) have made the first confirmed "spintronic" device incorporating organic molecules, a potentially superior approach for innovative electronics that rely on the spin, and associated magnetic orientation, of electrons. view more (2006-10-13)
Spin-polarized electrons on demand
Many hopes are pinned on spintronics. In the future it could replace electronics, which in the race to produce increasingly rapid computer components, must at sometime reach its limits. Different from electronics, where whole electrons are moved (the digital "one" means "an electron is present on the component", zero means... view more... (2009-01-22)
Exotic Materials Using Neptunium, Plutonium Provide Insight into Superconductivity
Physicists at Rutgers and Columbia universities have gained new insight into the origins of superconductivity - a property of metals where electrical resistance vanishes - by studying exotic chemical compounds that contain neptunium and plutonium. view more (2008-07-22)
K-State's fast laser research and theory building on Einsten's work by timing electrons emissions
Ultrafast laser research at Kansas State University has allowed physicists to build on Nobel Prize-winning work in photo-electronics by none other than Albert Einstein. view more (2009-05-22)
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)
Killer electrons in space are now less mysterious
A rare, timely conjunction of ground-based instrumentation and a dozen satellites has helped scientists better understand how electrons in space can turn into 'killers'. ESA's Cluster constellation has contributed crucially to the finding. view more (2007-07-27)
Electrons 'tunnel' through water molecules between nestled proteins
Duke University theoretical chemists who spend much of their time calculating how the exotic rules of quantum mechanics govern electrons motion between and through biological molecules have garnered surprising results when they add water to their models. view more (2005-11-28)
Superconductivity: Which one of these is not like the other?
Superconductivity appears to rely on very different mechanisms in two varieties of iron-based superconductors. view more (2009-07-13)
New Technique Studies How Plastic Solar Cells Turn Sunlight into Electricity
A new analytical technique that uses infrared spectroscopy to study light-sensitive organic materials could lead to the development of cheaper, more efficient solar cells. view more (2006-12-12)
HERA GETS GOING WITH ELECTRONS
The Hadron Electron Ring Accelerator (HERA) at the DESY laboratory in Hamburg is about to begin operations for 1998 with a return to electrons. Since 1993, the machine has been producing head-on collisions between high-energy protons and positrons - the antimatter equivalent of electrons. Now it is ready to get going with electrons again. view more (1998-08-11)
U of T team heats up gold to surprising effect: it gets harder not softer
Common sense tells us that when you heat something up it gets softer, but a team of researchers, led by University of Toronto chemistry and physics professor R.J. Dwayne Miller, has demonstrated the exact opposite. view more (2009-01-23)
Faster than ever seen before - speeding electrons will be snapped by new UK attosecond 'camera'
Ultrafast lasers helping to make some of the shortest pulses of light ever seen in the UK will be at the heart of a new system to capture the movements of electrons as they whizz around the nucleus of atoms. A UKP3.5 million research grant from the UK Research Councils' Basic Technology Programme announced today has been awarded to a team of... view more... (2003-01-15)
Researchers Create Model of Cancer-Preventing Enzyme, Study How It Works
Proline dehydrogenase is important because it plays a role in apoptosis, the process of cell death, by enabling the creation of superoxide, a highly reactive electron-rich oxygen species. view more (2007-05-14)
Technology May Cool The Laptop
Does your laptop sometimes get so hot that it can almost be used to fry eggs? view more (2009-10-30)
UNH scientists report first findings on key astrophysics problem
n a paper published recently in the journal Nature Physics, an international team of space scientists led by researchers from the University of New Hampshire present findings on the first experimental evidence that points in a new direction toward the solution of a longstanding, central problem of plasma astrophysics and space physics. view more (2007-11-29)
Graphene yields secrets to its extraordinary properties
Applying innovative measurement techniques, researchers from the Georgia Institute of Technology and the National Institute of Standards and Technology (NIST) have directly measured the unusual energy spectrum of graphene, a technologically promising, two-dimensional form of carbon that has tantalized and puzzled scientists since its discovery in... view more...

UBC physicists develop 'impossible' technique to study and develop superconductors
A team of University of British Columbia researchers has developed a technique that controls the number of electrons on the surface of high-temperature superconductors, a procedure considered impossible for the past two decades. view more (2008-06-24)
Really Hot Stars
Spectacular VLT Photos Unveil Mysterious Nebulae Quite a few of the most beautiful objects in the Universe are still shrouded in mystery. Even though most of the nebulae of gas and dust in our vicinity are now rather well understood, there are some which continue to puzzle astronomers. This is the case of a small number of unusual nebulae that... view more... (2003-04-09)
UCSB physicists move 1 step closer to quantum computing
Physicists at UC Santa Barbara have made an important advance in electrically controlling quantum states of electrons, a step that could help in the development of quantum computing. view more (2009-11-20)
