Newly installed technology enables clinicians to target lung and other tumors quickly and precisely using finely shaped radiation beams rather than surgery NORMAL, Ill., June 2, 2014 /PRNewswire/ -- When a diagnostic chest X-ray revealed a nodule on his left lung, Paul Hoffman, 79, had a biopsy and soon got bad news: it was Stage 1 lung cancer. He was given two options. The first was surgery, which would have been risky because Hoffman has a heart condition and a pacemaker. The...

Helmholtz Zentrum München Scientists at the Helmholtz Zentrum München (HMGU) working in cooperation with the Ludwig-Maximilians-Universität Hospital and the Technische Universität München (TUM) have for the first time tested X-ray dark-field radiography on a living organism to diagnose lung disease. This enables highly detailed images of the lung to be produced. As the team reports in the Investigative Radiology, this method shows promise in detecting diseases such as pulmonary...

Surprising Similarities In The Way Immune System Defenders Bind To Disease-causing Invaders
2014-05-27 03:50:47

By Glenn Roberts Jr., Stanford University A study led by researchers at Stanford's School of Medicine reveals how T cells, the immune system's foot soldiers, respond to an enormous number of potential health threats. X-ray studies at the Department of Energy's SLAC National Accelerator Laboratory, combined with Stanford biological studies and computational analysis, revealed remarkable similarities in the structure of binding sites, which allow a given T cell to recognize many...

Light Converted To Sound For Weapons Detection, Medical Imaging
2014-05-20 03:22:07

Nicole Casal Moore, University of Michigan A device that essentially listens for light waves could help open up the last frontier of the electromagnetic spectrum—the terahertz range. So-called T-rays, which are light waves too long for human eyes to see, could help airport security guards find chemical and other weapons. They might let doctors image body tissues with less damage to healthy areas. And they could give astronomers new tools to study planets in other solar systems. Those...

ESA’s New X-ray Optics To Observe The Hot Universe
2014-05-16 03:41:51

ESA A new idea to use super-polished silicon wafers as the heart of a telescope is set to reveal more of the hot, high-energy Universe, peering back into its turbulent history. Invisible X-rays tell us about the very hot matter in the Universe – black holes, supernovas and superheated gas clouds. Today’s X-ray observatories, ESA’s XMM-Newton and NASA’s Chandra, were launched in the last century, and are still delivering world-class science. But they are starting to age. To...

New Insight Into Formation Of Star Clusters Provided By NASA's Chandra X-ray Observatory
2014-05-16 03:44:41

[ Watch The Video: A Tour Of The Flame Nebula ] Harvard-Smithsonian Center for Astrophysics Stars are often born in clusters, in giant clouds of gas and dust. Astronomers have studied two star clusters using NASA's Chandra X-ray Observatory and infrared telescopes and the results show that the simplest ideas for the birth of these clusters cannot work. This composite image shows one of the clusters, NGC 2024, which is found in the center of the so-called Flame Nebula about 1,400...

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...
