NewsMotion capture: In a world first, motility apparatus of Mycoplasma mobile clarified
Mycoplasmas, including bacteria that cause pneumonia in humans, are generally nonmotile, but Mycoplasma mobile, as the species name suggests, has been found in the gills of fish and seems to move by gliding along surfaces. The molecular structure that allows it to do so has for the first time been ...

NewsIsolated population of chlamydia-free koalas even more vulnerable to the disease
Koalas in south-western Sydney are among the very few in New South Wales (NSW) still free of chlamydia, yet a new study shows they are less likely to adapt to the disease should it arrive on their doorstep.
