For the first time, living bacteria have been captured by X-ray, researchers report. Researchers from Uppsala University are working at the Department of Energy's SLAC National Accelerator Laboratory, Menlo Park, Calif, which is operated by Stanford University. This discovery, which offers a fresh way to view active biological samples, could lead to X-ray forays into mechanisms integral...

Scientists have found people’s genes haven’t retained as many fragments of viral DNA as other mammals, maybe due in part to our adoption of tools in lieu of teeth during conquest. Thus, exposure to viruses lurking in the blood may have been lessened. This is not to say people don’t harbor bits of DNA from viruses...

Scientists find just a few microbes are needed to infect lymph node, cause disease A long-held theory about how bubonic plague is caused has been flipped on its head, according to scientists. Researchers from the UNC School of Medicine found that instead of using host cells, some of the plague-causing bacteria travel to lymph nodes in small...

Researchers have found that a protein vital for cell health that has recently been associated with cancer and diabetes, can juggle its cellular to-do list—in effect having two alike protein parts split the workload. A key protein for most life forms—the TH enzyme (transhydrogenase)—works inside mitochondria. “Despite its importance, TH has been one of the least-studied mitochondrial...
