These are methanotrophic microcosms that are being used to develop and test new approaches to modeling microbial biogeochemistry using thermodynamic approaches (namely, the principle of maximum entropy production).
This is a Winogradsky column that Joseph Vallino uses in a SES course on Methods in Microbial Ecology. Almost every bacterial metabolic process that occurs on Earth also occurs in these columns that are simply constructed by placing freshwater or marine sediments augmented with a carbon source (such as saw dust) and fertilizer (N and P) in a column and topping it off with either fresh or sea water. Julie Huber is a co-instructor in the course.
Two black and white photos of different sides of an embryo. The right photo is labelled "left side neutral" and the left photo is labelled "right side shield".
13 black and white photographs of different stages of chick limb bud development. The limb buds have been removed from the embryo and are placed on a black background. Stages 23 through 35 are pictured. Wing buds are pictured on top, leg buds on the bottom.
Three black and white photos of cells. The photos have been labelled along the side with times (2:40, 2:45, 2:50), and several cells in each have been marked with a red dot.
