Multiple human diseases, the ciliopathies, are caused by defective cilia. In recent decades, much underlying ultrastructural and biochemical complexity of these important organelles has been discovered, but many questions remain unanswered. Dr. Brown will discuss cilia assembly, the ciliopathies, and the work he and his students have been doing to understand the mechanism of cilia gene regulation. 2023-02-17T00:00:00Z http://hdl.handle.net/20.500.13013/2883 Reconstructing Environments of the Past: In what conditions did our ancestors survive and thrive? Beck, Catherine From the earliest primates to modern humans, our history as a species has been characterized by environmental change and variability. Through studying the geological record we can reconstruct the past environments associated with fossil primates and hominins. This allows us to build and test hypotheses about how climatic and tectonic processes shaped the eastern African ecosystems in which our species evolved and ultimately migrated from to colonize the globe. 2023-02-16T00:00:00Z http://hdl.handle.net/20.500.13013/2885 What is the role of citrullination in ALS? Camille, Webb Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease. Degeneration of motor neurons occurs because of toxic protein aggregation. Protein Citrullination (PC) is altered dynamically in the spinal cord during disease progression and accumulates in protein aggregates. This presentation aims to discuss what is currently known and uncover novel proteins that are citrullinated in ALS. 2023-02-17T00:00:00Z http://hdl.handle.net/20.500.13013/2882 A Voice in the Wilderness: A Pioneering Biologist Explains How Evolution Can Help Us Solve our Biggest Problems. Graves, Joseph L. Evolutionary science has long been regarded as conservative, a tool for enforcing regressive ideas, particularly about race and gender. But in A Voice in the Wilderness, evolutionary biologist Joseph L. Graves Jr.—once styled as the “Black Darwin”—argues that his field is essential to social justice. He shows, for example, why biological races do not exist. He dismantles recent work in “human biodiversity” seeking genes to explain the achievements of different ethnic groups. He decimates homophobia, sexism, and classism as well. 2023-02-15T00:00:00Z
