See how microscopic organisms that most people have never seen are useful. Meet Dr. Brian Huber, paleobiologist at the National Museum of Natural History. Brian specializes on tiny organisms called foraminifera (forams) that are great indicators of global changes. Take a journey with Brian into the stories forams tell about conditions on Earth millions of years ago. Watch how fossilized forams are collected from deep oceans and Antarctic ice. Visit an icy place that used to be warm enough for marine reptiles. Consider what Brian's findings suggest for future conditions on Earth, including global climate.

For more than 100 days a year, Fernan Lake falls under health warnings because of toxic blue-green algae blooms. Resident Marc Andrews says you could see the lake turning color. “It’s starting to look more like pea soup instead of water.” Lake managers and residents turned to scientists from the MILES project at the University of Idaho to help them understand what was happening.

Bubonic Plague

This video segment from A Science Odyssey recounts the tactics employed by San Francisco's health officials to prevent bubonic plague from reaching America's West Coast. Using physical examinations, quarantines, and deportation, city officials hoped to isolate disease-carrying immigrants from the general population. They also disinfected people and fumigated properties where disease-carrying rodents were thought to exist. Following the 1906 earthquake, medical research began to consider rats, rather than humans, as the vector responsible for transmitting the disease. Scientists in India discovered that, in fact, it was the fleas carried by rats that were ultimately responsible for transmitting bubonic plague from diseased rats to humans.

This video produced by WGBH features Cathy Drennan, Professor of Chemistry and Biology at the Massachusetts Institute of Technology. Cathy explains that her research focuses on microorganisms that live off carbon dioxide, one of several greenhouse gases that are widely believed to accelerate global warming. Specifically, Cathy is investigating how a protein inside these microorganisms converts carbon dioxide into energy. Ultimately, Cathy hopes humans might apply what they learn from microorganisms to remove carbon dioxide from the environment.
