Middle school students learn about microbial cooperation and quorum sensing while becoming young scientists for a day. Here we see a culture of the bacteria Vibrio fischeri illuminated by a blue light transilluminator.
Graduate students John Coffin and Bryan Frenette pulling a seine net through a creek in Oklahoma to catch fish in water polluted with heavy metals (why the water is so orange).
Microscope photograph of the male reproductive organ from an Atlantic molly (Poecilia mexicana). Researchers at K-State are trying to figure out how differences in reproductive structures between Atlantic mollies from different habitats might lead to the formation of new species.

Algae contrasted against rhodamine dye in Kings Creek at Konza Prairie Biological Station. Dye’s like this are sometimes used to measure the flow-path of the water in a stream.

The infrared gas analyzer in action, using a laser to measure the carbon dioxide taken in as well as the oxygen and water released by the grass leaf it’s attached to.
A photograph of the internal structures of a Big Bluestem leaf taken under a microscope. Seton uses photographs like these to compare structural differences among grass populations. The letters label some of the different structures Seton measures. Photo Credit: Seton Bachle
A. A male Atlantic molly from a regular freshwater stream. B. A male molly from a toxic sulfidic stream. C. An area where a clear freshwater stream (left) and cloudy sulfidic stream (right) flow together.
Algae (left) release simple carbon compounds while tree leaves (right) release more complex carbon compounds that are not as easy for microbes to use for energy.
A section of grassland stream surrounded by grasses and shrubs (left) and a second section with tree canopy cover (right). Sophie conducts her experiments in both types of habitats to look for differences in carbon processing.
