Abstracts:
"Benefits of cooperation and communication in bacteria"
Sandeep Krishna, National Centre for Biological Sciences, Bangalore, India

Individual bacteria excrete many common goods, such as exoenzymes, siderophores, biofilm products and virulence factors, which can benefit the functioning and growth of not only themselves but also other individuals in their surroundings. I'll discuss how the functional form of this benefit affects the decision of whether to turn on or turn off production of the common good, and how communication between bacteria may then become crucial for making such decisions correctly.

"Modeling intracellular regulation: Transcription factor kinetics"
Andreas Grönlund, UPSC, Umeå University

Basic physical constraints in how macromolecules are made and how fast they can find each other in the intracellular environment constrain the fidelity of cellular regulation. These two properties are recently studied experimentally as well as analytically. I will give a brief overview of how such processes can be characterized and modeled.
