Cool discovery of bactriophage infection that uses a head filament to catch bacterial flagellum. And the motions of the flagellum then draw the virus in and then away to increase chances of infection. Quite cool bit of detective work to reveal years of interesting infection rate data.

From the article: Researchers have come up with a new idea for a light microscope. They placed between the light source and the object a lens made from a slab of a crystalline substance called gallium phosphide. This design drastically reduces the theoretical minimum size of a visible object. However, for complex technical reasons, no one has ever managed to get close to this theoretical minimum with a standard lens made of gallium phosphide. So the researchers took a different tack. They started by etching the lens with sulphuric acid, producing a frosted surface that, far from focusing the light, scattered it randomly in all directions. They then used a computer to design an incoming light wave that, when scattered by the lens, would focus to a point. This process of randomize and reconstruct produces a tighter focus than simply focusing the light with a traditional lens.

Very clever.

"The images taken with the scanning electron microscope of sauerkraut, kombucha, and some stinky cheeses show beautiful and complex landscapes made by and of microbes."

Really cool EM images of food bugs.
