Well, it’s been a while since I’ve posted anything about plants (never-ish maybe), so here’s a bit of a showcase on the skills of a group of organisms that we normally see as stationary!
Let’s start off our week by exploring our bodies, shall we? No, I’m not about to start a Sex Ed course (even though that could get hilarious). Scientific American is offering us a chance to become familiar with the micro-organisms that inhabit our bodies.
The body contains 10 times more bacteria, fungi and other micro-organisms than human cells. Most of these species are harmless—although they can still cause illness if they wind up in the wrong place. In addition, researchers are beginning to learn exactly how some microbial species in the body help digestion and contribute to regulation of appetite and the immune system.

Using confocal microscopy, which had been used for years to observe protein distribution in a cell, scientists have now seen the structure of proteins between cells.
To create the image above, Meininger and his colleague Michael Hill used fluorescent tags to label different components of an arteriole wall; cells are labeled in green, whereas elastin—a stretchy protein that holds the vascular cells together—is labeled in red. By taking a series of images with a confocal microscope, which relies on point illumination to eliminate out-of-focus areas, the researchers were able to construct a 3-D view of the blood vessel’s architecture.
