Glacial Size as a Trigger for the Mid-Pleistocene Transition: The Role of the solid Earth in Pleistocene climate -- by Dr. Harriet Lau

Milankovitch cycles — i.e., modulations in Earth's insolation due to variability in Earth'€™s orbit — are thought to pace ice ages over the last 2.6 million years (the Pleistocene), with dominant orbital periods occurring at ~20,000 and ~41,000-years, associated with changes in precession and obliquity, respectively. While Milankovitch periods have not changed significantly over several tens of millions of years, Earth's climatic response has. The Mid Pleistocene Transition (MPT), ~1 million years ago, is characterized by an enigmatic change between ice age cycles that occurred on predominantly ~41,000-year to ~100,000-year periodicities. In this talk, I will discuss the role of the solid Earth (the mantle and the lithosphere) in various aspects of the Pleistocene ice ages, including the MPT.

Cyanobacteria and their Xtreme campus life -- by Kaylah Marcello, UC Davis
Five undergraduate researchers interested in astrobiology spent the summer and fall investigating Cyanobacteria that live in the grit outside the EPS building and in other extreme environments right here on the UCD campus. They will present their work revealing surprisingly diverse communities influenced by variations in environment. The students are continuing their research with their advisors, Dr. Dawn Sumner and PhD student, Kaylah Marcello.
