Prof Gibson gives his Inauguration lecture at Warwick Medical School

image

On 26th June, Professor Matthew Gibson gave his inuagral ('leading lights') lecture at Warwick Medical School. This is a celebration of his promotion to a personal chair (professorship) joint between Warwick Medical School and the Department of Chemistry. After introductions by Prof Sudhesh Kumar (WMS Dean) and Prof Martin Wills (HoD of Chemistry) Matt introduced his career path on his way to Warwick, sharing success (and failures!) along the way. He then described two areas of research where his group actively works with his Medical School (and Life Sciences) colleagues; Glycoscience to study infection and new cell cryo-storage methods.

Following this, the Group had a Cocktail night to celebrate this, and future group successes!

Group attend APME 2017

7 Members of the group attended the APME (Advanced polymers via macromolecular engineering) conference in Gent. The group presented posters cover a diverse range of topics from bacterial biosensors, synthesis of poly(ampholytes), near antifreeze-protein mimetic polymers and glycopolymers for anti-adhesion therapy. Matt gave an invited lecture discussing the synthesis and most importantly activity of glycomaterials for infection. Our new approaches to make this process more high-throughput was also introduced.

Sucessful Launch of Polymers to Near-Space!

image

Our collaboration with Edgecombe Community College, NC, USA, funded by a Nasa outreach grant resulted in the high-altitude balloon launch on Saturday. Our polymers were sent up added to several biological samples. Due to the polymers ability to mimic the function of natural antifreeze proteins, the cells (blood and algae) were protected from teh extreme cold stress and survived the (bumpy) journey.

Anti-Bacterial Polymers Published in Biomacromolecules

image

Our latest work, in collaboration with the Fullam group at the School of Life Sciences has been published in ACS Biomacromolecules. This is part of our larger collaboration, including an Innovation grant from the MRC, into new methods for addressing the challenge of antimicrobial resistance. Traditional antimicrobials function by targetting a specific enzyme/pathway, which often enables resistance to develop. We are interested in moving from single target/small molecule paradigm to more innovative targets. In this work, we wanted to evaluate cationic polymers as anti-mycobacterial agents. Cationic polymers are extremely well studied, but mostly against pathogenic gram-negative organisms. Mycobacteria, which are a unique class of gram positive micro-organisms, which include Mycobaterium Tuberculosis have not been studied. We found that poly(dimethyl aminoethyl methacrylate) was particularly potent against a non-pathogenic mycobacterium (M. smegmatis). Interestingly, the polymer did not appear to lyse the cell membranes, which is the assumed mode of action, but less active cationic polymers did. Electron microscopy analysis suggested the cell-walls were being stressed. We are currently investigating this in more detail.

GibsonGroup in Space; Live 8th April

On Saturday, 8th April, a high altitidue balloon will be launched to over 60,000 ft, containing an experiment designed in collaboration with the GibsonGroup. This is part of a NASA-sponsered program, being undertaken by students at Edgecombe Community College, in Carolina, USA. The balloon will contain equipment for monitoring the external environment and also cameras; the Balloon will be high enough for the curvature of the Earth to be clearly visible. A secondary payload will also be included, enabling an additional science experiment. Jilian Leary, a student at the College contacted Professor Gibson to see if our cryo-protective polymers, inspired by antifreeze proteins could be included in an experiment to see how cells (blood) survive in the harsh conditions.

The launch will be live on facebook on 8th April (evening, UK time),

Group Outreach for World TB Day

image

On Friday 24th March members of the group took part in World TB day. The aim of the day was to reach out to local communities to inform them of the re-occurance of TB as a disease not just from low-income countries and is no longer a disease consigned to history. There were 10.4 million new cases in 2015 and 1.8 million deaths globally. In order to increase public awareness, on World TB day, we went to Cannon park shopping center to spread the word that TB is still not defeated. Activities for both adults and children, as twitter photograph competition, cross-word puzzle and coloring competition gave the opportunity not only to inform the public about key facts of TB but also to win prizes. Over 350 people visited the stall during the day.

Chris Stubbs Invited to Join SCI Materials Chemistry Committee

image

Chris, a 2nd year PhD student in the Gibson group, was recently invited to join the materials chemistry subcommittee of the society of chemical industry. This is a group comprised of PhD students, post-doctoral researchers, and early career academics as well as recent graduates and post-doctoral staff from within the materials chemistry industry. The intent of the subcommittee is to be responsible for representing the materials division of the SCI on social media, whilst also increasing its representation within universities, and encouraging collaboration between their industrial partners and early career principal investigators. The subcommittee is currently arranging social events, conferences and talks which engage final year undergraduates and PhD students, with the intention of encouraging them to pursue careers within the chemical industry. At the most recent meeting, Chris gave a talk entitled "Synthetic Polymers to Mimic Antifreeze Proteins".
