Reingold Cropped

Craig Reingold, fourth-year graduate student in the Nuclear Science Laboratory working with the group of Prof. Anna Simon, spent ten weeks in summer 2018 at the Lawrence Livermore National Laboratory. He joined the Academic Cooperation Program at Lawrence Livermore National Laboratory which hosts up to 800 undergraduate and graduate students each year. The program is designed to encourage external collaborations with LLNL. His stay at LLNL was also partially funded by CENTAUR: Center for Excellence in Nuclear Training and University-based Research. CENTAUR is a five-year grant from National Nuclear Security Administration (NNSA) that is focused on training the next generation of nuclear physics

Gomez Orlando

Orlando Gomez, a third-year graduate student working in the Nuclear Science Laboratory with Prof. Anna Simon, received the Glenn T. Seaborg Institute at Lawrence Livermore National Laboratory "Nuclear Forensics Summer Internship". The internship provides a stipend and travel cost reimbursement for a graduate student who is then paired with an LLNL scientist for a two-month program. The student joins the research group at LLNL and works on a project directly related to the efforts of the group.…

Notre Dame researchers determine spin-down rate of rare white dwarf pulsar

Robert Stiller 250

University of Notre Dame researchers have pinpointed the rate at which the only known white dwarf pulsar is slowing its rotation, finally confirming that the star’s spin-down energy is sufficient to power the unique light variations observed from the system.

“Evolutionary Biophysics”
 
Michael J Harms, Chemistry & Biochemistry, Institute of Molecular Biology, University of Oregon
 
Abstract:
 

How does protein biochemistry shape protein evolution?  How do new biochemical features evolve?  To answer these questions, the Harms lab studies protein evolution using phylogenetic analyses, computational and experimental studies of protein “sequence space”, and rigorous studies of protein biochemistry.  I will discuss two ongoing projects.  In the first, we ask the deceptively simple question: why can’t we predict the combined effect of mutations by summing their individual effects?  Through a set of computational and experimental studies, we demonstrate that universal thermodynamic considerations explain why mutations do not combine additively.  Inspired by these results, we are developing quantitative, mechanistic models to account for non-additivity between mutations—potentially leading to predictive models of protein evolution.  In the second project, we are investigating the evolution of the innate immune protein S100A9.  This protein can exist as either a pro-inflammatory homodimer or as an antimicrobial heterodimer with the protein S100A8. We found that the heterodimer arose from an ancient homomeric interface that was maintained after gene duplication.  The key historical mutations that conferred inflammatory and antimicrobial activity have different effects when introduced into the homodimer versus the heterodimer.  This allowed a small protein to acquire new functions without compromising existing functions.  We suspect this may be a general mode my which multifunctional proteins evolve.

Weak makes us strong: neutrinos in the multi-messenger era

Prof. Liliana Caballero
University of Guelph

We are entering an era of unprecedented capabilities for astronomical observations. The analysis of signals in multiple bands, i.e.,  gravitational waves, gamma and X-ray emissions, will provide detailed insight about the physics of diverse astrophysical phenomena such as the synthesis of heavy elements and the mechanism of stellar explosions. Neutrinos provide extra pieces to those long standing puzzles by playing a fundamental role in the evolution of supernovae, neutron star mergers and accretion disks around black holes. In this colloquium, I will discuss the connection between neutrinos and these compact objects and will present results on gravitational wave signals, neutrino observations and their possible detection at cosmological scale.
