From the top of the structure, showing its wonderful symmetry.
Space-filling model from the top, revealing the symmetry of seven sub-units that unite to form the complete structure.
Space filling model from below, showing how the sub-units create the barrel-like structure seen in the first image.
Hemolysin’s name provides a vital clue to its function. Staphylococcus aureus inserts hemolysin into the membranes of red blood cells, resulting in their rupture, leading to potentially fatal episodes of meningitis, pneumonia, and toxic shock.
“an idea that never got as far as an official title, but it was essentially “Black Avengers.” It was “Let’s put all the African or African-American heroes together on a team for an adventure,” and in those cases…
Alya Red, a project of the Barcelona Supercomputing Center that tries to understand the wondrous organ that is the heart and when the mechanism fails. The simulator generates electrical signals to try and exactly mimic the speed at which the signals propagate across the heart. An attempt to create an accurate electro-mechanical model of a heartbeat all with the help of 10,000 processors.
Oh and while you are at it check out her other site Anatomy UK
Anatomy UK is a site run by Emily to reflect anatomical creativity both in the UK and worldwide. The new exciting creative ideas emerging that have been inspired by anatomy are continually pushing the boundaries of how we perceive it…. it’s no longer just for the academics.
I emphasized that last part. Spread the word. Histology is growing. Heart it.
An eminent philosopher among my friends, who can dignify even your ugly furniture by lifting it into the serene light of science, has shown me this pregnant little fact. Your pier-glass or extensive surface of polished steel made to be rubbed by a housemaid, will be minutely and multitudinously scratched in all directions; but place now against it a lighted candle as a centre of illumination, and lo! the scratches will seem to arrange themselves in a fine series of concentric circles round that little sun.

These things are a parable. The scratches are events, and the candle is the egoism of any person…
