X-ray Study Reveals Formation Of Iridium Trihydride At High Pressure
2013-11-20 10:34:40

Desy An international team of researchers has synthesized a new material that stores an unusually large amount of hydrogen. Performing high-pressure X-ray studies at DESY’s PETRA III and other light sources, the scientists detected the formation of previously unobserved iridium hydride from hydrogen and metallic iridium at a pressure of 55 gigapascals (GPa), corresponding to approximately 550,000 times the Earth’s atmospheric pressure. The new material can store up to three times more...

Black Hole Jets Found To Contain Atomic Matter
2013-11-14 04:36:35

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have long wondered exactly what the enigmatic jets given off by black holes are made of. Now, an international team of scientists, writing in the journal Nature, has apparently solved the mystery and discovered the composition of those high-speed beams of matter. Using the European Space Agency’s (ESA) XMM-Newton observatory, lead author Dr. María Díaz Trigo and colleagues studied a black hole binary system located...

Medical Media Images has developed a new, advanced process to convert conventional Black and White X-Ray and MRI images into Color. Viewers can now see and learn information never seen before on X-Rays and MRI scans. Denver, Colorado (PRWEB) November 07, 2013 Medical Media Images, a Denver, Colorado based company, offers the world a first view of X-Ray and MRI Images in Color. MMI launched its first products in September, 2013 following nearly 2 years of product development. Similar to...

Before having any medical imaging test, such as a CT scan or x-ray, a woman should ask her doctor how the test will be used to guide her treatment and whether the benefits outweigh the risks. Boston, MA (PRWEB) November 07, 2013 When doctors recommend imaging tests such as magnetic resonance imaging (MRI) or computed tomography (CT) scans, many people don't ask questions—they just assume that it's the right thing to do. Yet medical imaging isn't always necessary or...

Abell 2142, also called A2142 and located in the constellation Corona Borealis, is an X-ray luminous galaxy cluster. Its creation is due to the merger between two galaxy clusters. It is one of the largest objects in the universe and is six million light years across. It holds hundreds of galaxies and enough gas to make a thousand more. The pressure fronts in the system have been traced in detail and are relatively cool 50 million degree Celsius. The central region is embedded in large...

X-Ray Astronomy -- Although the more energetic X-rays (E > 30 keV) can penetrate the air at least for distances of a few meters (they would never have been detected and medical X-ray machines would not work if this was not the case) the Earth's atmosphere is thick enough that virtually none are able to penetrate from outer space all the way to the Earth's surface. X-rays in the 0.5 - 5 keV range, where most celestial sources give off the bulk of their energy, can be stopped by a few...

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...

X-ray Binaries -- X-ray binaries are a class of binary stars that are very luminous in X-rays. The X-rays are produced by matter falling from one component (usually a relatively normal star) to the other component, which is a neutron star or a black hole. The infalling matter releases gravitational potential energy, up to several tens of per cent of its rest mass as X-rays. (Hydrogen fusion releases about 0.7 per cent of rest mass) X-ray binaries are further subdivided into...

Variable Star -- Most stars are of nearly constant luminosity. Our own Sun is a good example which goes through practically no measurable variation in brightness. There are, however, stars which do vary in brightness, called variable stars. They fall into two main groups: Intrinsic variables These are stars which have intrinsic variations in brightness, that is the star itself gets brighter and dimmer. There are many types of intrinsic variables, the main types being: -- Mira...

  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
