Lawrence Berkeley National Laboratory Provides New Insight into Genome Integrity and Biological Detection of Mismatched DNA Errors in the human genetic code that arise from mismatched nucleotide base pairs in the DNA double helix can lead to cancer and other disorders. In microbes, such errors provide the basis for adaption to environmental stress. As one of the first responders to these genetic errors, a small protein called MutS – for “Mutator S” – controls the integrity of...

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...

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...

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...

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...

Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
