Google Hearts Microbiology

Today is a great day to do a google search. Google celebrates the 161st birthday of Richard Petri with a Doodle. Petri is the inventor or the plate that bears his name and is used by microbiologists, genetics, molecular biologists, etc. the world over. His wife also made an tremendous contribution to microbiology, by suggesting the use of seaweed extract (red algae to be specific) as a base for the growth medium used in the plates.
