Space Radiation Detectors Placed Onboard Space Station
2012-12-22 06:07:15

[ Watch the Video: Solar Eruption in Full HD ] redOrbit Staff & Wire Reports - Your Universe Online During his trip to the International Space Station (ISS), Canadian astronaut Chris Hadfield carried with him a new set of instruments designed to help measure the amount of radiation an astronaut absorbs during a typical trip into space. The radiation measured by the devices is called neutron radiation. It is one of the more dangerous types officials from the Canadian Space Agency...

Quantum Spin Liquid Is A New State Of Magnetism
2012-12-21 09:38:33

redOrbit Staff & Wire Reports - Your Universe Online While experts had previously only confirmed the existence of two states of magnetism, experts from the Massachusetts Institute of Technology (MIT) report that they have been able to experimentally demonstrate the existence of a third kind. The MIT researchers have dubbed the new state a quantum spin liquid (QSL), and they describe their findings in this week's edition of the journal Nature. It joins ferromagnetism (the simple form...

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...

Protecting Astronauts From Radiation
2012-11-10 10:46:10

April Flowers for redOrbit.com — Your Universe Online NASA scientists and engineers have been working since Neil Armstrong and Buzz Aldrin first stepped on the surface of the moon to solve the complexities of traveling to and working in space that present significant challenges to the astronauts. One of those challenges is the space radiation that humans are subjected to when they go outside Earth's protective atmosphere and magnetic field. Plans are afoot to send astronauts...

Analysis will help development of new treatments to protect vulnerable patients undergoing chemotherapy or suffering from HIV Neutron scattering experiments have provided new insights into the origin of the side effects of an antifungal drug prescribed all over the world. The analysis conducted by scientists at King's College London and the Institut Laue-Langevin in Grenoble, and published in Scientific Reports, follows 40 years of debate and could help drug developers reduce these harmful...

Unprecedented Look At Quantum Oscillations Through Neutron Experiments
2012-10-23 13:30:32

Researchers at the Department of Energy's Oak Ridge National Laboratory have found that nitrogen atoms in the compound uranium nitride exhibit unexpected, distinct vibrations that form a nearly ideal realization of a physics textbook model known as the isotropic quantum harmonic oscillator. In the experiment on the uranium nitride crystal -- with each of the light nitrogen atoms centered in a cage of heavier uranium atoms -- neutron scattering at ORNL's Spallation Neutron Source (SNS)...

Mapping The Nuclear Landscape
2012-06-28 04:15:29

An Oak Ridge National Laboratory and University of Tennessee team has used the Department of Energy's Jaguar supercomputer to calculate the number of isotopes allowed by the laws of physics. The team, led by Witek Nazarewicz, used a quantum approach known as density functional theory, applying it independently to six leading models of the nuclear interaction to determine that there are about 7,000 possible combinations of protons and neutrons allowed in bound nuclei with up to 120 protons (a...

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...
