The world's newest "super microscope" at Isis in Oxfordshire will allow scientists to see things 10,000 times thinner than a human hair. The machine is known as a pulsed neutron source. And now that the second target station "Isis 2" is open, up to 40 different experiments can run side by side. Physicists from around the world are flying in to seek an audience with the oracle, which resides at the Rutherford Appleton Laboratory, at Harwell Science and Innovation Campus. "Essentially, it's a...

A team of researchers in Canada have made a bold stride in the struggle to detect dark matter. The PICASSO collaboration has documented the discovery of a significant difference between the acoustic signals induced by neutrons and alpha particles in a detector based on superheated liquids. Since neutron induced signals are very similar to dark matter induced signals, this new discovery, published today, Thursday, 16 October, in the New Journal of Physics, could lead to improved background...

New analytical tools coming on line at the Spallation Neutron Source, the Department of Energy's state-of-the-art neutron science facility at Oak Ridge National Laboratory, include a beam line dedicated to nuclear physics studies. The Fundamental Neutron Physics Beam Line (FNPB) has opened its shutter to receive neutrons for the first time. Among the nuclear physics studies planned for the new, intense beam line are experiments that probe the neutron-related mysteries associated with the "Big...

By The Associated Press GENEVA (AP) - A small blip on a computer screen sent champagne corks popping among physicists in Switzerland. Near Chicago, researchers at a "pajama party" who watched via satellite let out an early morning cheer.The blip was literally of cosmic proportions, representing a new tool to probe the birth of the universe.The world's largest atom smasher passed its first test Wednesday as scientists said their powerful tool is almost ready to reveal how the tiniest...

Using observations from NASA's Rossi X-ray Timing Explorer (RXTE), an international team of astronomers has discovered a timing mechanism that allows them to predict exactly when a superdense star will unleash incredibly powerful explosions. "We found a clock that ticks slower and slower, and when it slows down too much, boom! The bomb explodes," says lead author Diego Altamirano of the University of Amsterdam in the Netherlands. The bursts occur on a neutron star, which is the collapsed...

3-D images are not only useful in medicine; the observation of internal structures is also invaluable in many other fields of scientific investigation. Recently, researchers from the Hahn-Meitner-Institute (HMI) in Berlin in cooperation with University of Applied Sciences in Berlin have succeeded, for the first time, in a direct, three-dimensional visualization of magnetic fields inside solid, non-transparent materials. This is announced by Nikolay Kardjilov and colleagues in the current...

One of the great ongoing challenges of astrophysics, to find out how stars evolve and die, is to be tackled in an ambitious European research program. This will involve studying in the laboratory over 25 critical nuclear reactions using low-energy stable beams of ions, in order to understand stellar evolution. "This program will enhance the ongoing effort to understand the lifecycle of stars, together with the structure and processes of stellar evolution," said the workshop's convenor...

Researchers at the National Institute of Standards and Technology (NIST) and the University of Maryland have developed a new optical method that can detect individual neutrons and record them over a range of intensities at least a hundred times greater than existing detectors. The new detector, described at the March Meeting of the American Physical Society* by Charles Clark, a Fellow of the Joint Quantum Institute of NIST and the University of Maryland, promises to improve existing neutron...

High-energy physicists devoted to recreating the conditions at the beginning of the universe have for the first time observed a new way to produce those basic particles of atoms, protons and neutrons.Confirming a decades-old prediction, the physicists with the CLEO collaboration say they observed a rare and extremely short-lived subatomic particle with the unusual name of "charmed-strange meson" decay into a proton and anti-neutron.Detection of the event, which the collaboration made public...

CSIs now have a new tool in their belt: the chemical signatures left by local drinking water in human hair. Scientists at the University of Utah have found that the ratios of different forms of hydrogen and oxygen in local drinking water vary from region to region across the country. These elements are incorporated into the hair as it grows. Traces in the hair can show where a person has recently lived or traveled, and could help police track the recent movements of criminals. "You are...

X-ray Burster -- X-ray bursters are a class of binary stars which are luminous in X-rays. They contain a neutron star and a low-mass companion star. The companion fills its Roche lobe and therefore the neutron star is accreting matter from it. The inflowing gas forms an accretion disk around the neutron star. Sometimes X-ray bursters show a sudden increase in their X-ray luminosity, called X-ray burst. All properties of the X-ray bursts can be explained assuming that they result from...
