McBride shows DNA detective work with paper-eating bacteria that 'glide'

...ome carbohydrate polymers may be connected in both gliding microbes." McBride and his students have used F. johnsoniae to study the motility of gliding bacteria for more than a decade. They cloned "mutants" of F. johnsoniae that are unable to move, an...

Like a snail through the intestinal canal

...y material works simultaneously as a lubricant for gliding on and as a glue which the slug can grip hold of. An intestinal robot should also have a similar layer to use. To achieve this, an adhesive layer is added to the mucus-like properties, which allows the device to be stuck to the layer of mucus. The a...

The glowing waters appear to extend to the horizon in all directions, and can last from several hours to several days. They are thought to be caused by enormous populations of bacterial bio...

Wright bros. upstaged! Dinos invented biplanes

...ctly from the ground, against gravity, without any gliding stage. Such long feathers around the feet would make it hard for Microraptor to run on the ground, says Chatterjee, supporting the idea that it was a tree dweller, thus reinforcing the trees-down theory. ...
