Natasha Rhys to serve as Associate Chair at upcoming GRS

13 May 2014

Natasha Rhys, a PhD student from the MNP group at University of Leeds, will be serving as the Associate Chair at this year's Gordon Research Seminar (GRS) in USA. The focus of the seminar is around Water & Aqueous Solutions and will run from 26th - 27th July 2014.

The GRS is followed by the Gordon Research Conference (GRC), which runs from 27th July - 1st August this year, both being held at Holderness School, Holderness, NH, USA.

A new atomic force microscope for cross-faculty biomedical research

8 May 2014

In 2013 Dr. Neil Thomson led a successful equipment bid to the Wellcome Trust to purchase a new higher speed atomic force microscope.

Dr. Thomson successfully acquired funds for a new atomic force microscope (AFM) through the annual Wellcome Trust equipment call which funds new state-of-the-art equipment for cutting-edge biomedical research to be used by multiple users in academic institutions. This was a cross-faculty bid that was supported financially by three of the STEM faculties; FMH, FBS and MaPS. The co-applicants from across these faculties were; Dr. Simon Connell, Dr. David Brockwell, Prof. Stephen Evans, Prof. Eileen Ingham, Prof. Sheena Radford, Prof. Mark Harris and Prof. Jennifer Kirkham. The total funds granted by the Wellcome Trust came to £343,707 with additional support in equal measure from the three faculties.

An atomic force microscope or AFM, is a high resolution surface profiling instrument that can produce topographical images of biological specimens. It can be operated in aqueous liquid and humid enviornments making it adept at probing biological materials and tissue without fixation and/or addition of contrast agents. It measures force through the use of a micro-cantilever sensor, so as well as imaging specimens it can measure their local mechanical properties. The AFM feels the specimen surface through a sharp tip at the end of the force sensor, which can have a radius less than 10nm. This gives the AFM the capability of measuring the nanoscale properties of materials and to acquire images of biological processes in situ.

Conventional AFM technology has been limited in the image acquisition time due to mechanical inertia associated with scanning a sensor across the surface. The new instrument increases the imaging speed by up to 100 times principally by reducing the size of the force sensor. This will enable our researchers to greatly increase data collection throughput and allow visulisation of biomedical relevant processes.

The new Bruker Dimension Fast Scan Bio AFM has been installed in the Leeds AFM facility situated in the School of Physics and Astronomy from the beginning of 2014.

Physical Sciences and Oncology Away Day success

10th April

The School of Physics and Astronomy recently hosted a Physical Sciences and Oncology Away Day for the Faculty of MaPS. The delegate list included clinicians from the field of Oncology, it was an opportunity for both the Physical Scientists and Clinicians to get together to discuss the challenges. There were 40 delegates in total on the day.

Professor Steve Evans, Head of Group in MNP and Director of Research for the School, led the day and arranged for the following topics to be discussed:

Steve Smye gave an overall introduction to the challenges that researchers in the field are currently facing and David Buckley gave a brief talk about Imaging.

Understanding disease (Basic Sciences/Modelling), introduced by Professor Pam Jones

Diagnostics (Imaging/Sensing) presented by Mr Greg Taylor from St James Hospital

Treatment (Imaging/Delivery) by Professor Peter Selby

Vivian Cosgrove also gave a brief introduction to Radiotherapy Physics Research

The day comprised of small group discussions and workshops, looking at refining the challenges, developing solutions and finally feeding back to the rest of the group.

The intention of the day was to develop new collaborations, we are pleased to say that a very positive outcome was established and we hope to be taking these new ideas forward very soon.

Thank you to everyone who was involved in the organisation of the day and for those delegates who took part in what we can confidently say was a very successful day.

 

Megan Hughes wins best presentation at recent PG Symposium

4th April 2014

Congratulations to Miss Megan Hughes on being awarded the best presentation at this years Postrgraduate Symposium, held on Tuesday 1st April 2014.

Megan is part of the Dougan group in Molecular & Nanoscale Physics and is currently focusing her research on physics proteins, which are biological molecules with very important functions in the cell. These molecules have unique 3D shapes and Megan is interested in the importance of the forces that hold this 3D shape together.

PhD position: New single molecule techniques for understanding protein-DNA interactions

28th March

DEADLINE: 1st MAY 2014

BACKGROUND

Protein-DNA interactions are central to many major cellular processes, including transcription, replication, and packaging of DNA into chromatin. However, we still know very little about how proteins interact physically with DNA. Without this basic knowledge we will be unable to understand many of the processes underpinning nucleic acid metabolism. New approaches are therefore required to probe directly how proteins bind to and manipulate DNA.

THE PROJECT

The project will exploit novel single molecule approaches to examine protein-DNA complexes with unprecedented molecular resolution. The ability to control, manipulate and interrogate single molecules will provide powerful insight into the function of these systems and, ultimately, will help us to understand the processes that underpin all aspects of nucleic acid metabolism. The project will make use of novel direct physical approaches to characterise the stability, flexibility and function of protein-DNA complexes (force clamp AFM) and will benefit from the unique collection of skills and experience of the research team.

The project is a collaboration between Dr Lorna Dougan in Physics at Leeds and Prof Peter McGlynn  in Biology at York.

THE NETWORK

This project forms part of a new White Rose studentship network “New single molecule techniques for understanding the physics of living systems” and is made up of a team of collaborators from the Universities of Sheffield, Leeds and York. The goal of the network is to develop new physical approaches to answer biological questions and new ways for working collaboratively across the physics-life science interface to maximise the impact of these approaches.
