U.S. physicists say they've determined the crusts of neutron stars are 10 billion times stronger than steel or any other metal alloy found on Earth. The scientists said a neutron star is a star that collapsed when its core ceased nuclear fusion. Exhibiting extreme gravity while rotating as fast as 700 times per second, a teaspoonful of neutron star matter would weight about 100 million tons, the researchers said. Indiana University Professor Charles Horowitz and colleagues conducted...

Research by a theoretical physicist at Indiana University shows that the crusts of neutron stars are 10 billion times stronger than steel or any other of the earth's strongest metal alloys. Charles Horowitz, a professor in the IU College of Arts and Sciences' Department of Physics, came to the conclusion after large-scale molecular dynamics computer simulations were conducted at Indiana University and Los Alamos National Laboratory in New Mexico. The research will appear Friday (May 8) in...

A small, dense object only twelve miles in diameter is responsible for this beautiful X-ray nebula that spans 150 light years. At the center of this image made by NASA's Chandra X-ray Observatory is a very young and powerful pulsar, known as PSR B1509-58, or B1509 for short. The pulsar is a rapidly spinning neutron star which is spewing energy out into the space around it to create complex and intriguing structures, including one that resembles a large cosmic hand. In this image, the lowest...

A U.S. Navy laboratory has produced "significant" evidence of the controversial energy source known as cold fusion, the Associated Press reported. Researchers are calling it the first clear visual evidence that low-energy nuclear reaction (LENR), or cold fusion devices can produce neutrons capable of nuclear reactions. Analytical chemist Pamela Mosier-Boss of the U.S. Navy's Space and Naval Warfare Systems Center (SPAWAR) in San Diego, California, called the finding "very significant."...

New evidence for existence of controversial energy source Researchers are reporting compelling new scientific evidence for the existence of low-energy nuclear reactions (LENR), the process once called "cold fusion" that may promise a new source of energy. One group of scientists, for instance, describes what it terms the first clear visual evidence that LENR devices can produce neutrons, subatomic particles that scientists view as tell-tale signs that nuclear reactions are occurring....

Roman artifacts which are nearly two thousand years old with similarities to ancient remains found at Pompeii in Italy were examined at the Science and Technology Facilities Council's ISIS neutron source last weekend. (21-22 February 2009). Researchers hope to learn more about our heritage by discovering whether the items were imported from southern Italy, or manufactured using similar techniques in Britain. The bronze artifacts, which include a wine-mixing vessel, jugs and ceremonial...

DFPase from the squid Loligo vulgaris analyzed by neutron diffractionThe enzyme DFPase from the squid Loligo vulgaris, is able to rapidly and efficiently detoxify chemical warfare agents such as Sarin, which was used in the Tokyo subway attacks in 1995. A detailed understanding of the mechanism by which enzymes catalyze chemical reactions is necessary for efforts aiming to improve their properties. A group of researchers at the University of Frankfurt, the Bundeswehr Institute for...

The U.S. Department of Energy has given its initial approval to begin plans for a second target station for the Spallation Neutron Source, expanding what is already the world's most powerful pulsed neutron scattering facility located at DOE's Oak Ridge National Laboratory.The Critical Decision Zero (CD-0) status is the first step in an approximately $1 billion construction project. The Second Target Station (STS) will be optimized for nanoscale and biological sciences with an emphasis on...

With help from newly developed equipment designed and built at Michigan State University, MSU researchers have been able to make first-of-its-kind measurements of several rare nuclei, one of which has been termed a "holy grail" of experimental nuclear physics. The discoveries, made at MSU's National Superconducting Cyclotron Laboratory using an isotope purification device, will help to refine theoretical models about how elements are created in the cosmos. Until now, this was beyond the...

Calibration tool will reveal when hypothetical particles are detected Several research projects are underway to try to detect particles that may make up the mysterious "dark matter" believed to dominate the universe's mass. But the existing detectors have a problem: They also pick up particles of ordinary matter -- hurtling neutrons that masquerade as the elusive dark-matter particles the instruments are designed to find. MIT physicist Jocelyn Monroe has a solution. A new detector she and her...

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...
