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...

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...

Researchers including members from the Niels Bohr Institute at the University of Copenhagen have developed a new method for making detailed X-ray images of brain cells. The method, called SAXS-CT, can map the myelin sheaths of nerve cells, which are important for conditions such as multiple sclerosis and Alzheimer's disease. The results have been published in the scientific journal, NeuroImage. The myelin sheaths of nerve cells are lamellar membranes surrounding the neuronal axons. The myelin...

Scientists at the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory have developed a fast and efficient way to determine the structure of proteins, shortening a process that often takes years into a matter of days. The high-throughput protein pipeline could allow scientists to expedite the development of biofuels, decipher how extremophiles thrive in conditions that kill most organisms, and better understand how proteins carry out life's vital functions. The technique...
