"Principles underlying cellular protein production"
Protein biosynthesis is by far the largest consumer of energy during cellular proliferation. The tremendous cost associated with protein synthesis makes it a key step for regulating diverse cellular functions. Therefore, determining how a cell allocates its synthesis capacity for each protein will provide a foundational piece of information for systems biology. I will describe our approach to address this gap of knowledge using quantitative and genome-wide methods monitoring cellular protein synthesis. Our study revealed the general principles governing protein production that cells have acquired to optimize the utilization of limited resources. More broadly, this approach provides a enabling tool for quantitative cell biology and precise biological engineering.

Hamilton Colloquium Series - Dr. Justin Kasper, University of Michigan; Smithsonian Astrophysical Observatory: "Sending a spacecraft to the Sun"
For centuries solar eclipses have provided brief glimpses of the solar corona, a remarkably structured atmosphere that surrounds the Sun and spreads into the solar system. Today, the Sun and the corona are tracked continuously by observatories on Earth and in space. We know much more about solar activity and the impact space weather can have on society than ever before, but we have not been able to answer fundamental questions about the Sun. Why is the corona millions of degrees hotter than the visible surface of the Sun? How does the corona drive a supersonic solar wind? How are solar flares and eruptions able to produce storms of radiation? It has long been recognized that the only way to unambiguously answer these questions is to send an instrumented probe close to the Sun. In 2018 we will finally embark on this journey with the Solar Probe Plus spacecraft, a NASA mission that will repeatedly plunge through the corona to obtain the first direct samples of the Sun. The mission will be reviewed, with a focus on the physics of the solar corona and the design of plasma instruments capable of both making the necessary measurements and of surviving the solar encounters.

High Energy Theory Seminar - Aron Wall, University of California, Santa Barbara - Superselection Sectors in AdS/CFT
"AdS/CFT is a duality relating the degrees of freedom in a D dimensional bulk gravity theory to a (D-1) dimensional theory living on the boundary.
I will argue that in fact the boundary theory contains only a subset of the bulk observables. For each state of the boundary theory, there are multiple bulk states dual to it, which can be operationally distinguished by observers who fall across event horizons. Based on arXiv:1210.3590."
