About the Single Molecule Discussion Group
The SMDG series started in September 2006 and are organized by Tamara Chiba. This is a great place where faculty, postdocs and students meet once a month to discuss single molecule research conducted at Yale as well as litterature in a relaxed and informal atmosphere with great food from Nica's Market!
The SMDG meetings are unique in bringing together researchers from various departments, including Physics, Engineering and Applied Sciences, Molecular Biophysics and Biochemistry, and Biology to discuss topics of common interest.
During the first 30 min a speaker presents his/her current research work as well as the various difficulties they might have encountered. This is an excellent opportunity to discuss and exchange ideas amongst the diverse group. The second half of the meeting is dedicated to the presentation and discussion of a journal article by a second speaker.
The speakers are comprised of faculty, postdocs, and students. We encourage volunteers to come forward for a presentation. Remember it's only a 30 min discussion, and you don't have to have cool data yet, just talk about what you are working on.
Hope to see you there!

“Advances in Single Molecule Biophysics: Measurements of Kinesin and Actin Machinery”
Friday Feb 29th, Bass 405 12-1pm, Food from Nica's Market at 11:45
Abstract: An overview of a number of single molecule biophysics advances will be provided including combined optical trapping and single molecule FRET, new strategies for forming single molecule assays using the M13 bacteriophage as a linker, and demonstration of trapping objects on silicon wafers. Measurements will also be presented that test a novel mechanism for the kinesin power stroke, recently proposed by Hwang, Lang and Karplus. The kinesin measurements compare stall forces and single molecule motility records for wild type vs. mutants in the cover neck bundle. The development of an assay for probing rupture force between single actin filaments and actin binding proteins will also be presented. These studies compare the likelihood of unfolding vs. unbinding in filamin and a-actinin.
