Biophysics Seminar

Naama Brenner (Technion) "Universal protein distributions in cell populations"

Mon, Apr 8, 2013, 12:00 pm to 1:00 pm
The protein content of a cell is a primary determinant of its phenotype. Yet, large fluctuations in protein numbers are observed among genetically identical cells grown under identical conditions. Recently, cellular protein variability has been a hot topic of research, with microorganisms providing a popular model system.
Audience: Faculty, post docs, grads

Paul Chaikin (NYU) "Artificial self-replicating stuff"

Mon, Apr 1, 2013, 12:00 pm to 1:00 pm

Lunch @ 11:45, talk @ 12-1:00
Audience: Physics faculty, post docs, grads

Biophysics Seminar - Roman Stocker (MIT) "Spying on the lives of marine microbes: From biophysics to ecology "

Mon, Mar 25, 2013, 12:00 pm to 1:00 pm
At a time when microbial ecology is largely traveling along genomic roads, we cannot forget that the functions and services of microbes depend greatly on their behaviors, encounters, and interactions with their environment.
Audience: Physics faculty, post docs, grads

Henrik Flyvbjerg (Danish Technical University) "Optimal estimation of diffusion coefficients from noisy single-particle trajectories"

Mon, Mar 11, 2013, 12:00 pm to 1:00 pm
Einstein argued in 1905 that the mean squared displacement of a microscopic particle suspended in a fluid at rest is proportional to time with the constant of proportionality giving the particle's
Audience: Physics faculty, post docs, grads

Sebastian Maerkl, EPFL Lausanne "Large-scale single cell analysis"

Mon, Mar 4, 2013, 12:00 pm to 1:00 pm
Observing cellular responses to perturbations is central to generating and testing hypothesis in biology. Time-lapse microscopy is a powerful tool for studying cellular phenotypes, but has been refractory to proteome-wide investigations.
Audience: Physics faculty, post docs, grads

Christina Marchetti (Syracuse U.) "Phase separation and jamming of dense active matter"

Mon, Feb 25, 2013, 12:00 pm to 1:00 pm
Recent experiments on confluent layers of epithelial cells and vibrated granular media have motivated interest in the behavior of active systems at high density, where the interplay of steric repulsion and activity can yield active glassy or jammed states. In this talk I will discuss the behavior of dense collections of self-propelled particles in...
Audience: Physics faculty, post docs, grads

James Shapiro (U. Chicago) "The read-write genome"

Mon, Feb 18, 2013, 12:00 pm to 1:00 pm
The colloquium will discuss the ways that cells inscribe information onto and into their genomes at different time scales. These range from individual cell cycles to evolutionary time. The main emphasis will be on genomic inscriptions at the DNA level.
Audience: Physics faculty, post docs, grads

Doug Weibel (U. Wisconsin) "Regulation of bacterial biochemistry at strained bacterial membranes"

Mon, Feb 11, 2013, 12:00 pm to 1:00 pm
We are exploring an evolutionarily conserved mechanism for the localization and regulation of biochemistry at strained membranes in bacteria and mitochondria. In this talk, I highlight this mechanism by discussing the regulation of the universal and widely conserved DNA-repair protein, RecA.
Audience: Physics faculty, post docs, grads

Biophysics Seminar Series - Ariel Amir (Harvard) "Bacterial growth: defects, elasticity and plasticity"

Mon, Feb 4, 2013, 12:00 pm to 1:00 pm
Bacterial cells have rigid walls, which define their shape, and enable them to hold high internal pressure. While much is known about cell wall chemistry, the mechanisms controlling its growth remain elusive. The processes leading to the cylindrical shape of many bacteria are only now being unraveled.
Audience: Physics faculty, post docs, grads

Biophysics Seminar Series - Erel Levine, Harvard - "How to worm infection dynamics out of worms?"

Mon, Apr 30, 2012, 12:00 pm to 1:00 pm
Bacterial infection is characterized by a multi-scale noisy dynamics with unpredictable outcome. In my talk I introduce bacterial infection of the worm intestine as a minimal tractable model of bacterial infection. I discuss how this model could be used to address key questions in the field, and suggest experimental and theoretical approaches to...
