A project at the University of Tokyo has developed a mid-infrared microscopy platform offering an improved view of structures inside living bacteria. Described in Nature Photonics, the new nanoscope ...

A newly identified class of RNA molecules has been discovered in bacteria living inside the human body. These circular genetic structures, termed obelisks, differ from known viruses and bacteria and ...

Zinc sits at the heart of many bacterial enzymes, so one of our immune system's simplest defenses is to keep zinc out of reach. Calprotectin, a neutrophil protein abundant at infection sites, is ...

Scientists have discovered a strange tubular structure inside Profftella, a symbiotic bacterium in the Asian citrus psyllid. These long, helical tubes, filled with ribosomes, show a complexity not ...

In 1962 Heinz Stolp, a researcher in Berlin, was searching for new viruses when he ran out of the filters that sieved them from his samples. So he substituted filters with slightly larger holes: 1.35 ...

A research team at Leibniz-HKI has described a new enzyme that renders the highly toxic molecule malleicyprol harmless.
