Biochemistry converts DNA genomes into RNA, and this RNA gets transcribed into protein. Since the 1990s, we have learned that this is only part of the story. Scientists have found that RNA does much more than carry information. It can regulate expression of genes, act as an enzyme, and bind to specific targets - just like proteins - and each of these roles has been engineered in the lab. This course will provide a short survey of some of the surprising new roles researchers have found for RNA.

Soon after the publication of On the Origin of Species, Charles Darwin began exploring the hidden lives of the wildflowers growing in the woods and fields outside his country home. His eccentric observations and ingenious, homemade botanical experiments have been overshadowed by his much more famous work, but they led him to discover things no one in his day had ever noticed about surprisingly animal-like abilities of the living, sentient beings we know as plants. This two-session course, one lecture and one lab,  is a look at Darwin’s second, much less famous, journey of scientific discovery. First class meets at Roseville Lutheran; Second class session meets at the Plant Growth Facilities Lab Classroom #132, 1552 Gortner Ave, Falcon Heights, MN 55108. Park: Gortner Ramp, St. Paul Campus. 

Why are we here? Not Minnesota, or even Earth, but how is it that we (and life in general) can even exist in the universe? If you like lying awake at night thinking profound thoughts, then this is the right course for you. Whether you prefer the actions of a divine hand or the random vagaries of quantum chance, there will be plenty to chew on. We will combine presentations with open discussions on the mysteries of life. Weekly readings will be on the internet, and participants wishing more detailed discussions are encouraged to explore the recommended books.

Carbon dioxide is an integral component of life on Earth whose rising atmospheric concentrations have been one of the biggest contributors to rising temperatures in recent decades. To aid in climate change mitigation strategies and to tap into an abundant source of carbon, scientists have been researching the production of chemicals, pharmaceuticals, fuels, and materials from carbon dioxide captured from the air. This course introduces concepts of environmental science, chemistry, and scientific inquiry and collaboration in the context of scientists’ efforts to leverage carbon dioxide usage.
