023. Personal Genomes
Jack Bateman M  1:00 - 2:25
W  1:00 - 2:25
Druckenmiller-241
An introduction to the field of genetics and its impact on the modern world. As the cost of DNA sequence analysis plummets, many believe that sequencing entire genomes of individuals will soon become part of our routine preventive healthcare. How can information gleaned from your genome affect decisions about your health? Beyond medical applications, how might personal genetic information be used in other areas of your life, and society as a whole? What ethical, legal, and social issues are raised by widespread use of genetic information? These questions are explored through readings, discussion, and writing assignments.

TH 8:30 - 9:55
Druckenmiller-020
Focuses on the structure and function of cells as we have come to know them through the interpretation of direct observations and experimental results. Emphasis is on the scientific (thought) processes that have allowed us to understand what we know today, emphasizing the use of genetic, biochemical, and optical analysis to understand fundamental biological processes. Covers details of the organization and expression of genetic information, and the biosynthesis, sorting, and function of cellular components within the cell. Concludes with examples of how cells perceive signals from other cells within cell populations, tissues, organisms, and the environment. Three hours of lab each week. Chemistry 225 is recommended.

Druckenmiller-020
Examines the quantitative and qualitative characterization of organismal morphology, and explores the relationship of morphology to measurable components of an organism’s mechanical, hydrodynamic, and ecological environment. Lectures, labs, field trips, and individual research projects emphasize (1) analysis of morphology, including analyses of the shape of individual organisms as well as of the mechanical and molecular organization of their tissues; (2) characterization of water flow associated with organisms; and (3) analyses of the ecological and mechanical consequences to organisms of their interaction with their environment. Introductory physics and calculus are strongly recommended.

Peter Woodruff M  2:30 - 3:55Druckenmiller-004
Comprehensive laboratory course in molecular biology and biochemistry that reflects how research is conducted and communicated. Includes sequential weekly experiments, resulting in a cohesive, semester-long research project. Begins with genetic engineering to produce a recombinant protein, continues with its purification, and finishes with functional and structural characterization. Emphasis is on cloning strategy, controlling protein expression, and protein characterization using techniques such as polymerase chain reaction, affinity chromatography, isoelectric focusing, and high-performance liquid chromatography.

302. Earth Climate History and Its Impacts on Ecosystems and Human Civilizations
Philip Camill T  8:30 - 9:55
TH 8:30 - 9:55
Searles-213
The modern world is experiencing rapid climate warming and some parts extreme drought, which will have dramatic impacts on ecosystems and human societies. How do contemporary warming and aridity compare to past changes in climate? Are modern changes human-caused or part of the natural variability in the climate system? What effects did past changes have on global ecosystems and human societies? Uses the past as context for evaluating changes in the modern world. Students use sediment and growth records (ocean, glacier, lake, coral, tree ring, and rodent middens) to assemble proxies for past changes in climate, atmospheric CO2, and disturbance to examine several issues: how tectonics and orogeny affect long-term carbon cycling and climate, the rise of C4 photosynthesis and the evolution of grazing mammals, orbital forcing and glacial cycle theory/evidence, glacial refugia and post-glacial species migrations, climate change and the rise of human civilizations, climate/overkill hypothesis of Pleistocene megafauna, patterns and mechanisms of climate variability, drought cycles, how climate change affects disturbances like fire, climate-related collapses of human civilizations, and how models can be used to weigh the relative effects of natural variability and human-caused climate change. Prior enrollment in a 200- or 300-level environmental studies or geology course is recommended.

307. Evolutionary Developmental Biology

329. Neuronal Regeneration
Hadley Horch W  1:00 - 3:55Druckenmiller-110
The consequences of neuronal damage in humans, especially in the brain and spinal cord, are frequently devastating and permanent. Invertebrates, on the other hand, are often capable of complete functional regeneration. This course examines the varied responses to neuronal injury in a range of species. Topics include neuronal regeneration in planaria, insects, amphibians, and mammals. Students read and discuss original papers from the literature in an attempt to understand the basis of the radically different regenerative responses mounted by a variety of neuronal systems.
