Posted by Chuck Bednar on October 30th, 2016
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 […]

Posted by PaV on October 17th, 2016
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 […]

Posted by Laura M. Faure on October 5th, 2016
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.
