Biophysics Seminar

Biophysics Seminar - Manu Prakash, Stanford “Life in Flatland: Complex morphogenetic and behavioral traits of a simple basal metazoan.”

Biophysics Seminar - Marcelo Magnasco, Rockefeller University

Mon, Sep 28, 2015, 12:00 pm to 1:00 pm

Biophysics Seminar - Anatoly B. Kolomeisky, Rice "How to Understand Mechanism of Protein Search for Targets on DNA"

Mon, Sep 21, 2015, 12:00 pm to 1:00 pm
One of the most critical aspects of protein functioning in cells is the ability of protein molecules to quickly find and recognize specific targets on DNA. Kinetic measurements indicate that in many cases the corresponding association rates are surprisingly large.

Biophysics Seminar - Jonathan Howard, Yale - “Ciliary and flagellar motility: From single molecules to collective motion"

Mon, Apr 27, 2015, 12:00 pm to 1:00 pm
Cilia and flagella are slender cellular appendages that have motile, sensory and regulatory roles. They drive the movement of cells through fluids, thereby powering the swimming of spermatozoa and ciliated microorganisms, and they drive the movement of fluid past cells, thereby generating fluid and mucus flows in the airways, reproductive tracts...

Biophysics Seminar - Nikta Fakhri, MIT - "TBA"

Mon, Apr 13, 2015, 12:00 pm to 1:00 pm

Lunch @ 11:45, talk @ 12pm.

Biophysics Seminar - Marc Gershow, NYU - "TBA"

Mon, Apr 6, 2015, 1:00 pm

Lunch @ 11:45, talk @ 12pm.

Biophysics Seminar - Sidhartha Goyal, U. Toronto - “Finding the rules of blood regeneration”

Mon, Mar 30, 2015, 12:00 pm to 1:00 pm
Much of complex biology results from interactions among a large number of individually simpler elements. Blood regeneration is no different. About 100 billion new blood cells are made everyday from a much smaller yet a large population of diverse stem cell population.

Biophysics Seminar - Michael Levin, Tufts - “Endogenous voltage gradients among non-neural tissues encode large-scale patterning cues in embryogenes

Mon, Mar 23, 2015, 12:00 pm to 1:00 pm
The big challenge in modern biology is to understand and control the mechanisms by which living organisms organize, maintain, remodel, and restore their shape.

Biophysics Seminar - Dan Larson, NIH - "Single-molecule imaging reveals switch between spurious and functional ncRNA transcription"

Mon, Mar 9, 2015, 12:00 pm to 1:00 pm
In recent years, through parallel advances in microscopy, fluorescent probe development, and computational modeling, it has become possible to describe gene expression in a fundamentally different way: one can now directly observe single molecules of RNA in living and fixed cells using the fluorescence microscope.

Biophysics Seminar - Yann Chemla, UIUC - “Measurement of Flagellar and Whole-cell Dynamics in Swimming E. coli Cells”

Mon, Feb 23, 2015, 12:00 pm to 1:00 pm
Bacterial chemotaxis is a paradigm for how environmental signals modulate behavior. Escherichia coli, like many species of bacteria, swim by rotating a bundle of helical flagella driven by bi-directional rotary motors.

Biophysics Seminar - Coleen Murphy, Princeton - "Fatal Attraction: The links between mating, reproductive behavior, and longevity"

Mon, Feb 16, 2015, 12:00 pm to 1:00 pm
Longevity is a remarkably plastic trait, governed by genetic programs that enable organisms to respond appropriately to environmental cues. These genetic programs are highly conserved and were first discovered in model organisms such as yeast, worms, and flies. Germline-less and daf-2 insulin/IGF-1 signaling (IIS) mutants remain youthful and live...

Biophysics Seminar, Terry Hwa, UCSD

Mon, Dec 1, 2014, 12:00 pm to 1:00 pm
“A quantitative phenomenological approach towards predictive biology”
Lunch at 11:45, seminar is from 12-1:00.

Biophysics Seminar Jose Feijo, UMD "How cells coordinate growth and shape: unravelling the complexity of ion signaling in pollen tubes "

Mon, Nov 10, 2014, 12:00 pm to 1:00 pm
Pollen transcriptomics revealed the expression of of about 7.000 genes in pollen, but theoretical modelling suggests that the cooperation of all of these into the processes of wall surface and cytoplasmic volume production is a minimal condition to explain most of the morphogenic events that characterize these cells.

Biophysics Seminar - Denis Wirtz (Johns Hopkins U.) "Cell migration in 3D"

Biophysics Seminar - Surya Ganguli (Stanford)

Mon, Oct 13, 2014, 12:00 pm to 1:00 pm
“The functional contribution of synaptic complexity to learning and memory”

Biophysics Seminar, Timothy O'Leary (Brandeis) "Stable neural function from sloppy underlying components".

Mon, Oct 6, 2014, 12:00 pm to 1:00 pm

Catered lunch at 11:45, talk begins at 12 noon.

Biophysics Seminar - Wolfgang Losert - U. Maryland

Mon, Sep 22, 2014, 12:00 pm to 1:00 pm
“Follow the wave - a dynamic mechanism for contact guidance and collective cell migration.”
Lunch @ 11:45,seminar 12-1:00

Biophysics Seminar Series - Daniel Needleman (Harvard) "Self-Focusing of the Ran Gradient in Mitosis: Signaling, Mechanics, and Spindle Size"

Mon, Apr 28, 2014, 12:00 pm to 1:00 pm
During spindle assembly, microtubules are highly enriched near chromatin by a process which, in many systems, is driven by the GTPase Ran. The Ran pathway has been proposed to establish a reaction-diffusion network that generates gradients in the behaviors of soluble proteins around chromatin, but the manner in which this happens is poorly...

Biophysics Seminar Series - Massimo Vergassola (UCSD) “Finding the needle in a biological haystack”

Mon, Apr 14, 2014, 12:00 pm to 1:00 pm
Early T-cell activation is selected by evolution to discriminate a few foreign peptides rapidly from a vast excess of self-peptides, and it is unclear in quantitative terms how this is possible. It will be discussed how a generic proofreading cascade supplemented by a single negative feedback accounts quantitatively for early T-cell activation,...

Biophysics Seminar Series - Karen Kasza (Sloan Kettering) "Spatiotemporal control of the forces that shape tissues"

Mon, Apr 7, 2014, 12:00 pm to 1:00 pm
During embryonic development, the forces generated by myosin II must be controlled in space and time to shape simple epithelia into tissues and organs with complex form and structure.
