 | For years, the ratio of uranium's two long-lived isotopes, U-235 and U-238, has been considered invariant, despite measurements made in the mid-1970s that hinted otherwise. Now, with improved precision from state-of-the-art instrumentation, researchers at the University of Illinois unequivocally show this ratio actually does vary significantly in Earth materials. ...> Full Article |
 | More efficient lighting, lasers to observe the earth from space, and solar power - just some of the ways that the study of light can impact on climate change and a cutting edge area of the discipline of photonics. ...> Full Article |
 | Researchers at Michigan State University's National Superconducting Cyclotron Laboratory (NSCL) have created three isotopes of magnesium and aluminum. The results not only stake out new territory on the nuclear landscape, but also suggest that variants of everyday elements might exist that are heavier than current scientific models predict. ...> Full Article |
 | Want to help unravel the mysteries of the universe? A new distributed computing project allows people around the world to participate in cutting-edge cosmology research by donating their unused computing cycles. ...> Full Article |
 | Successes like this at a university reactor are actually starting to drive big ideas and big thoughts around the country and around the world. ...> Full Article |
 | An international collaboration has performed the first-ever atomic-detail computer simulation of how proteins vibrate in a crystal. ...> Full Article |
 | A novel device simply and conveniently traps, detects and manipulates the single spin of an electron, overcoming some major obstacles that have prevented progress toward spintronics and spin-based quantum computing. ...> Full Article |
 | A research team has created an easy-to-produce material from the stuff of computer chips that has the rare ability to bend light in the opposite direction from all naturally occurring materials. This startling property may contribute to significant advances in many areas, including high-speed communications, medical diagnostics and detection of terrorist threats. ...> Full Article |
 | The team of mathematicians that first created the mathematics behind the "invisibility cloak" announced by physicists last October has now shown that the same technology could be used to generate an "electromagnetic wormhole." ...> Full Article |
 | A form of 'shimmering' superconductivity may offer vital clues as to how superconductors work. ...> Full Article |
 | Scientist developing new imaging technology that uses neutrons to "see" materials and structures non-destructively at atomic and molecular scales. ...> Full Article |
A new study describes the different mechanisms by which magnetic fields and spin-polarized electrical currents affect magnetism.

 | Old physics challenge lures professor back into important science. ...> Full Article |
Scientists have introduced a new material that could be to computers of the future what silicon is to the computers of today.
...> Full Article
 | We've all been taught that our bodies, the Earth, and in fact all matter in the universe is composed of tiny building blocks called atoms. Now imagine if this weren't the case. This mind-bending concept is at the core of the scientific research that researchers all over the world—are pursuing. ...> Full Article |
In their normal state, electrons repel each other because of their charge, but in the state of superconductivity, electrons pair up.

 | New facility helps 'physics and chemistry push into biology' ...> Full Article |
 | Droplets of liquid have been shown to travel uphill, rather than sliding down as expected, when the surface they are on is vigorously shaken up and down. ...> Full Article |
 | In order to learn more about the origins of quantum dot blinking researchers have developed a method to characterize it on faster time scales than have previously been accessed. ...> Full Article |
 | Electrical cables, garden hoses and strands of holiday lights seem to get themselves hopelessly tangled with no help at all. Now research has resulted in the first model of how knots form. ...> Full Article |
