This week marked the end of an era for NASA researchers, as the space agency’s New Horizons mission transmitted the last data collected during its history-making July 2015 flyby of the dwarf planet Pluto via downlink to the Deep Space Network facility in Canberra, Australia. “The Pluto system data that New Horizons collected has amazed […]

Source: Biologists first to observe direct inheritance of gene-silencing RNA This is a really remarkable discovery, which throws all of population genetics into question. It will have to be rethought. Here’s part of the author’s own surprise: “It’s shocking that we can see dsRNA cross generational boundaries. Our results provide a concrete mechanism for how […]
Various rod-shaped bacteria mysteriously glide on surfaces in the absence of appendages such as flagella or pili. In the deltaproteobacterium Myxococcus xanthus, a putative gliding motility machinery (Agl–Glt) localizes to so-called Focal Adhesion sites (FA) that form stationary contact points with the underlying surface. We discovered that the Agl–Glt machinery contains an inner-membrane motor complex that moves intracellularly along a right-handed helical path, and when it becomes stationary at FA sites, it powers a left-handed rotation of the cell around its long axis. At FA sites, force transmission requires cyclic interactions between the molecular motor and adhesion proteins of the outer membrane via a periplasmic interaction platform, which presumably involves a contractile activity of motor components and possible interactions with the peptidoglycan. This work provides the first molecular model for bacterial gliding motility.
