Using electron microscopy and high-speed atomic force microscopy, researchers show the internal molecular motor behind the gliding mechanism for Mycoplasma mobile to consist of two ATP synthase-like molecules. Sharing a similar structure with ATP synthase suggests a common evolutionary ancestor. This synthase-like ATPase is challenging the origin of cells and proteins themselves.

Researchers from Osaka City University find that when the larva nematode C. elegans is fed a diet of Bacillus subtilis var. natto, a bacteria used to ferment soy beans into the traditional Japanese food natto, upon reaching adulthood these worms are able to survive infections from the gram-positive bacteria Staphylococcus aureus and Enterococcus faecalis longer than when fed a standard diet of non-pathogenic E. coli.

In collaboration with Kanazawa University, researchers from Osaka City University used high-speed atomic force microscopy (HS-AFM) to visualize at the nanometer level the movement of individual particles within the parasitic bacterium Mycoplasma mobile. After confirming the outline on the surface of the cell structure in an immobilized state with previous data gathered from electron microscopy, the team succeeded in visualizing the real-time movements of the internal structure by scanning the outside of the cell with HS-AFM.

Scientists have discovered an extremely rare species of cymothoid from the mouth of a museum specimen of a deep-sea shark caught from the East China Sea, suggesting its wide distribution around the globe.

Large, physically strong Masu salmon disperse farther when infected with parasites, potentially escaping from further infections at the contaminated site but ironically resulting in the greater expansion of the parasite, according to Hokkaido University researchers.
