Learn how life on the edge of volcanoes sheds light on the origin of life on earth and the possibility of life on other planets in these videos from NATURE: Living Volcanos. Join Dr. Jeff Marlow and his team as they explore Marum Volcano in the South Pacific. Dr. Marlow discovers life on the edge of Marum which builds a picture of what life might look like on other planets that have more extreme environments than most of Earth. In the accompanying classroom activity, students analyze data from Dr. Marlow’s exploration of the connection between rock formation and the microorganisms that live in the rocks. Additional support materials are available including discussion questions and vocabulary terms.

Victoria demonstrates the use of E. coli bacteria in the creation of synthetic blood. By altering the genetic make-up of E. coli, bioligists can use the spliced genes in the synthesis of everything from vaccines to biofuels and even the hemoglobin in human blood. There are complications with using this synthetic blood as a complete substitute in human bodies, but Victoria is hoping to excel beyond these roadblocks.

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.
