Berkeley Lab Researchers Unveil Technique for Easy Comparisons of Proteins in Solution A revolutionary X-ray analytical technique that enables researchers at a glance to identify structural similarities and differences between multiple proteins under a variety of conditions has been developed by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab). As a demonstration, the researchers used this technique to gain valuable new insight...
MAHWAH, N.J., March 19, 2013 /PRNewswire/ -- SPECTRO Analytical Instruments announces the introduction of its new SPECTROSCOUT Portable Energy Dispersive X-ray Fluorescence (ED-XRF) analyzer that enables rapid, laboratory-class elemental analysis of environmental and geological samples even in remote locations. The determination of elemental compositions onsite from far-flung mining and geological field operations to remote environmental locations presents substantial challenges....
Physikalisch-Technische Bundesanstalt (PTB) PTB and Dectris have developed a vacuum-compatible X-ray detector that allows the size of low-contrast nano-objects to be determined. Microvesicles are smallest cell elements which are present in all body fluids and are different, depending on whether a person is healthy or sick. This could contribute to detecting numerous diseases, such as, e.g., carcinomas, at an early stage, and to treating them more efficiently. The problem is that the...
KEENE, N.H. and AVENTURA, Fla., Sept. 24, 2012 /PRNewswire/ -- Cheshire Medical Center/Dartmouth-Hitchcock Keene's Linear Accelerator has the highest utilization rate in the state of NH and provides treatment to many cancer patients close to home. Because of the critical importance of this technology and service in our region, a planned replacement to the new Varian TrueBeam(TM) linear accelerator will occur over the next few months. During the changeover, we will have a temporary...
For the first time X-ray scientists have combined high-resolution imaging with 3-D viewing of the surface layer of material using X-ray vision in a way that does not damage the sample. This new technique expands the range of X-ray research possible for biology and many aspects of nanotechnology, particularly nanofilms, photonics, and micro- and nano-electronics. This new technique also reduces "guesswork" by eliminating the need for modeling-dependent structural simulation often used in...
A new advance in X-ray imaging has revealed the dramatic three-dimensional shape of gold nanocrystals, and is likely to shine a light on the structure of other nano-scale materials. Described today in Nature Communications, the new technique improves the quality of nanomaterial images, made using X-ray diffraction, by accurately correcting distortions in the X-ray light. Dr Jesse Clark, lead author of the study from the London Centre for Nanotechnology said: "With nanomaterials playing...
[Watch Video] Lee Rannals for redOrbit.com – Your Universe Online Astronomers have identified an X-ray signal that followed an observation made last year of a quiescent black hole in a distant galaxy. The black hole discovered by the team last year was seen erupting after shredding and consuming a passing star. Astronomers then witnessed days following the observation a distinctive X-ray signal that comes from matter on the verge of falling into the black hole. This...
Lee Rannals for redOrbit.com - Your Universe Online While some find it as the source of inspiration for wrapping gifts, Scotch tape inspired one scientist at NASA to build a special X-ray mirror. NASA scientist Maxim Markevitch and a team of X-ray optics experts at the space agency's Goddard Space Flight Center are looking into the feasibility of creating a low-cost mirror out of plastic tape. "I remember looking at a roll of Scotch tape and thinking, 'was it possible to use the same...
MOUNTAIN VIEW, Calif., July 26, 2012 /PRNewswire/ -- The continuous evolution of X-ray sources, detectors and software has led to a migration from analog to digital X-ray inspection systems in the nondestructive testing (NDT) industry. Digital X-rays' lower operating costs have given them a significant competitive advantage over film radiography solutions, as they eliminate the expenses involved in buying films, maintaining a darkroom, obtaining space for archiving film records,...
Using the compound eyes of the humble moth as their inspiration, an international team of physicists has developed new nanoscale materials that could someday reduce the radiation dosages received by patients getting X-rayed, while improving the resolution of the resulting images. The work, led by Yasha Yi-a professor of the City University of New York, who is also affiliated with Massachusetts Institute of Technology and New York University-was published today in the Optical Society's...

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 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...
