Public Talk: Biophysics at the nanoscale, one molecule at a time

Distinguished Professor Antoine van Oijen from the School of Chemistry and Molecular Bioscience, Molecular Horizons, at the University of Wollongong will be giving a public talk Thursday May 30th.

 

Summary of talk:

Advances in optical imaging and molecular manipulation techniques have made it possible to observe individual enzymes and record molecular movies that provide new insight into their dynamics and reaction mechanisms. In a biological context, most of these enzymes function in concert with other enzymes in multi-protein complexes, so an important direction is the utilization of single-molecule techniques to unravel the orchestration of large macromolecular assemblies. We are applying a single-molecule approach to study DNA replication, a process that is supported by a large, multi-protein complex containing a number of different activities. I will present recent results of single-molecule studies of replication in bacterial and eukaryotic systems, using approaches that rely on mechanical manipulation of individual DNA molecules and the visualization of the fluorescence of individual, labelled replication proteins. Using these methods, we study the molecular mechanisms underlying the coordination at the replication fork of the various enzymatic activities that support DNA unwinding, priming, and synthesis.

 

Brief Biography of the Speaker:

Antoine van Oijen led research groups at Harvard Medical School and Groningen University (the Netherlands) before moving to the University of Wollongong in 2015 as an ARC Laureate Fellow. His research revolves around the development and use of single-molecule biophysical tools to study complex biological systems. In particular, he is interested in understanding the molecular principles underlying the process of bacterial DNA replication and repair. Using novel single-molecule fluorescence imaging and nano-manipulation techniques, his work has allowed the direct visualization of the dynamics of individual replication and repair complexes and has led to new insights into bacterial genomic maintenance and pathways leading to antibiotic resistance.

Western Sydney University NMR MRI & Diffusion Symposium/Workshop

Western Sydney University will be holding the 8th WSU Symposium on NMR MRI & Diffusion early in November. It will include two workshops (Magritek and Bruker) and the ANZMAG Annual General Meeting.

Registration and program information is available is through the link westernsydney.edu.au/MRIsymposium. Registration (regular $150; student $65) includes the evening networking dinner on the evening of the 8th November.

Students are encouraged to submit a poster of their work, prizes for the best poster will be presented and four lucky students will be nominated to give a 5-minute oral presentation at the symposium.

The Western Sydney University Symposium is held biennially and showcases theoretical developments and cutting edge applications of Magnetic Resonance Imaging (MRI) and Nuclear Magnetic Resonance (NMR) Diffusion measurements.

AIP Women in Physics lecture – Macquarie University

Special Public AIP Lecture Event – at Macquarie University
“Innovation with the most powerful lasers in the world”

Each year the Australian Institute of Physics (AIP) funds a national tour by an eminent female physicist. This year’s AIP Women in Physics lecturer will be Dr Ceri Brenner, an experimental physicist from the UK. Ceri’s AIP lecture in Sydney is in partnership with the Department of Physics and Astronomy at Macquarie University.

Ceri Brenner is a plasma physicist and innovator who uses the most powerful lasers in the world to study what happens when extreme bursts of light come into contact with matter and is using this knowledge to design new X-ray technology that can see through steel! The extreme physics she studies can also be applied for understanding supernova explosions in space or how we can ignite a star on earth for clean electricity generation.

When Ceri shines the CLF’s super-intense lasers at a solid, liquid or a gas, they super-heat to millions of degrees in less than a trillionth of a second and rip apart the material structure to transform into plasma—the fourth state of matter.
