Information, Computation, and Thermodynamics in Cells - by Pankaj Mehta

Cells live in complex and dynamic environments. Adapting to changing environments often requires cells to perform complex information processing, and cells have developed elaborate signaling networks to accomplish this feat. These biochemical networks are ubiquitous in biology. They range from naturally occurring biochemical networks in bacteria and higher organisms, to sophisticated synthetic cellular circuits that rewire cells to perform complex computations in response to specific inputs. The tremendous advances in our ability to understand and manipulate cellular information processing networks raise fundamental questions about the physics of information processing in living systems. I will discuss recent work in this direction trying to understand the fundamental constraints placed by (nonequilibrium) thermodynamics on the ability of cellular circuits to process information and perform computations and discuss the implications of our results for the emerging field of synthetic biology.

Cosmological Seed Magnetic Field from Inflation by Bharat Ratra

A cosmological magnetic field of nG strength on Mpc length scales could be the seed magnetic field needed
to explain observed few microG large-scale galactic magnetic fields. I first briefly review the observational
and theoretical motivations for such a seed field, two galactic magnetic field amplification models, and some
non-inflationary seed field generation scenarios. I then discuss an inflation magnetic field generation model.
I conclude by mentioning possible extensions of this model as well as potentially observable consequences.
