European Union. A Political Journey

College will host a major seminar serie entitled European Union: A Political Journey between November 3rd  and November 17th.  The series has been organised by College undergraduate L Ferrero (Political Science, Yr 2) and Volta representative for Acersat, the office of the University of Pavia that acts in support of a number of student's cultural and events.

The 'political journey' of the European Union has met remarkable challenges in the last 10-12 years. The social consequences of 2008 Financial Crisis hit the people of Europe in a major way and it was widely perceived that the financial tools and procedures available produced a slow and inadequate response to the social damage created by the crisis. But this was just the first of the last wave of challenges that the European Union had to face. The migrant crisis resulting from both the lasting conflicts in the Middle East and the social and political instability of large areas of the African continent has been met with indifference and limited responses at central European level leaving countries such as Italy and Greece at the mercy of events and unable - in many instances - to prevent huge human tragedies and loss of life.  Connected with the migrant crisis Europe has witnessed a remarkable surge of nationalism in many countries leading, in the case of the United Kingodom to a referendum that decided to take the country out of the European Union.  Finally, the crisis caused by the Covid-19 pandemic has exacerbated once more sharp divisions among member states although, in this instance, the institutions of the European Union have been able to agree a set of financial measures that may considerably assist the strain caused by the Covid emergency on the like of millions and millions of European citizens.

The seminar series European Union: A Political Journey basically asks the question as to whether the European Union has the ability to withstand these challenges and set a clear roadmap for the Union in years to come.  Speakers at the series will include Emma Bonino, one of the strongest advocates of the European project and herself a European Commissioner between 1994 and 1999 as well as four major scholars in the field of European Studies: Sophie Heine (Oxford University), Cetta Mainwaring (Glasgow University), Jerome Creel (Ecole Superieure du Commerce in Paris) and Simon Usherwood (Surrey University).  All College students are warmly invited to attend the events of this seminar series.

Seminars will be held online due to the restrictions imposed by the Covid-19 pandemic at 11.00 am on November 3rd, 10th, 12th adn 17th. The poster of the series can be downloaded here.

The links for connecting to the seminars via zoom are below.  Further information about the seminar series can be found on the relevant seminar pages accessible from the Seminars/Colloquia page of the College website. The webcasts of each seminar will be uploaded on the seminar pages for students unable to attend the seminars live on the above dates.

Abstract

The idea of a United States of Europe means a different Europe from the IMPERFECT one we already have, still paralysed by the criss-crossing vetoes by the member states that are slowing down the progress of deeper integration. Building on the existing one, we want to go forward making the EU stronger, more democratic, and able to face the challenges that can only be overcome if we stay together. Populism – usually going hand in hand with nationalism – aims to delegitimize the building of a new Europe, forgetting for example that today Europe has the most advanced level of social and health care and attention to the environment.

Biography
Emma Bonino is a member of the Italian Senate and was elected to Senate as a member of a cross political movement known as More Europe. She served as the Italian Minister of Foreign Affairs between 2013 and 2014, was deputy chair of the Italian Senate from 2008 and 2013 and was Minister for International Trade and European Affairs. First elected to the Italian Chamber of Deputies in 1976, she served either in the Italian or in the European Parliament continuously since then, except between 1994 and 1999 when she took the role of European Commissioner. In the years 1994 to 1999 she confronted the dissolution of former Yugoslavia and the humanitarian crisis that results from the conflict. She is a member of the Board of Trustees at the International Crisis Group (ICR), a co-chair of the council of Foreign Relations (ECFR ) and an active Member of the Radical Party.

Sophie Heine

Abstract
At a time when the European Union is increasingly criticised and exposed to fragmentation, pro Europeans need to build a coherent and convincing alternative project. defending the statu quo is no longer sufficient to resist anti European forces. European federalism should be deeply rethought and refurbished. In that respect, European sovereignty can constitute a concept, as long as it is combined with democratic and liberal principles.

Biography
Sophie Heine holds a bachelor degree in Politics, a master in European Studies, a master in international Relations and a PhD from the Institute for European Studies (Universite Libre de Bruxelles) that she accomplished with a scholarship from the Belgian Fund For Scientific Research- FNRS. She then did a post-doctoral research at Balliol College (Oxford University) partly funded by the Wiener-Anspach Foundation, before teaching for a year modules on European politics and International Politics at Queen Mary, University of London. In 2014, she became involved in the movement Stand Up for Europe by contributing to launching the movement and running for the European elections. She then became a Senior Research Fellow for the Egmont institute in Brussels and worked part time for Stand Up for Europe as its secretary General. Since 2016, she has been back as a research associate at Oxford University (Department for Politics and International relations), a freelance author and consultant as well as a dance teacher and choreographer. Sophie Heine has published numerous articles and several books on a variety of topic (Populism and Euroscepticism, Progressive ideologies, Left-wing movements and parties, liberalism and individual freedom, gender-related injustices, European federalism and sovereignty). Her most recent book, "For a sovereign Europe", has been published last November by Peter Lang (Oxford).

News from the Aurora-verse delivered by NMR spectroscopy

14h September 2020.  Mark Pfuhl, King's College London.

News from the Aurora-verse delivered by NMR spectroscopy


On the 14th of September Mark Pfuhl of King's College London will give a talk on News from the Aurora-verse delivered by NMR spectroscopy at 5.00 pm. The seminar will be deliverd online due to current restrictions on access to lecture theatres and the link for access is found on the seminar poster that can be downloaded here. All College students are invited to attend, especially those reading Medicine, Biology, Biotechnology and Pharmaceutical Sciences.

Abstract
Aurora-A kinase is an important regulator of the cell cycle and many other processes beyond. It also plays an important role in cancer so that it has become an important drug target. However, the success of Aurora-A targeted drugs at present is rather mixed so that a better understanding of this complex enzyme is required. Aurora-A is an unusual kinase that lacks a canonical on-off switch and its activity can be regulated by a combination of interactions with a plethora of accessory proteins and phosphorylation on multiple sites. I will present how NMR spectroscopy has been used in my group over the past years to make important contributions to better understand this enigmatic protein and its partners. This will include the redefinition of the domain architecture of the XMAP215 family (1), structure determination of a novel cryptic TOG domain (1,2) and its partner 4/5 helix domain (1,4), studies of conformation and interactions of small fragments of TACC3 with Aurora-A kinase (3,5), early stages of the development of novel anti-cancer drugs and a first glimpse of the conformation of the overlooked N-terminus of Aurora-A kinase.

Biography
Mark Pfuhl was born in Berlin where he went to school and where he initially studied Chemistry at the Technische Universität before moving on to Biochemistry at the Freie Universität. After graduating there in 1991 he moved to EMBL Heidelberg where he did his PhD in the group of A Pastore using NMR to determine the first structures of domains of the giant muscle proteins Nebulin and Titin. He finished his PhD in 1995 and - after a brief stint at the Université de Haute Normandie with F Toma in early 1996 - he moved to London on an EMBO long term post doc fellowship to work with P Driscoll at UCL. In 1998 he obtained a Royal Society University Research Fellowship for independent research at UCL. In 2001 he moved to the University of Leicester where he held a Lectureship in addition to his fellowship. In 2010 he returned to London to hold a Readership in cardiovascular structural biology in the then Randall Division of molecular and cellular biophysics. His main scientific interests are the regulation of muscle and kinase function which he studies using mainly NMR spectroscopy supported by other biochemical and biophysical methods.

Back on Track

For a few months the Volta website has been silent as much of the communication between the College and its students took place by internal emails.

The Covid-19 pandemic affected our College as it affect other Colleges in Pavia and other Collegiate Universities.  But two points clearly emerged from the crisis caused by the SARS Cov-2 virus:

(i)   Many Volta students elected to stay in College throughout the lockdown months. Although the College does not have the full data from other Colleges in Pavia it is clear that the occupancy of Volta throughout lockdown has been one of the highest if not the highest across University. And fortunately no Volta student has been infected by the virus or at least not in a recognisable, symptomatic way.

(ii) Volta made the point that teaching ought to continue throughout lockdown and College is indebted and very grateful to the following students (listed alphabetically): A Barone, G Burini, M Freiherr von Wangenheim, V Mangiaterra, S Merlini. D Nodari, O Najlani, I Rosignoli and the following external students or post-doctoral fellows (in alphabetical order): S Burgess, S Fofou Fotchi, P Minerba (a Volta alumnus), M Musci, E Naldi and I Rossinelli.

Together these students and post docs delivered 168 hours of Course material and 264 of supervisions, the majority of which was offered online, often with the help of graphic tables and unquestionably the teaching that College carried out notwithstanding Covid-19 and the ensuing lockdown contributed in a major way to the strong academic results achieved by the members of Volta by the end of July deadline and to be presented at the General Assembly that will take place early in October.

Volta and its members sincerely hope that the worst of the SARS Cov-2 may now be over but the College will maintain the strictest vigilance and enforce tight discipline in order to try and keep the virus outside the College boundaries and enable our students to have a safe and productive 2020/21 academic year at Volta.

Abstract
Blood cells sustain life through oxygen supply and resistance to infection. The hematopoietic system is a source of limitless production of blood cells. Genetic and environmental defects in this system causes hematologic cancers, anemias, and bone marrow failure syndromes. The ultimate goal of our study is to produce blood cells on petri dish so that can be transfused to patients [1]. To do so, understanding how blood cells develop in our body is essential. Blood cell development depends on network of cells. I propose the organ-on-a-chip platform to study network of cells in blood development [2]. This study will ultimately provide a fundamental molecular mechanism of human blood cell development.

Biography
My academic background comprises ten years of professional research experience as a stem cell biologist. I studied the role of microenvironmental signals in the maintenance of hematopoietic stem cells [3,4] and identified gene regulatory networks able to induce the formation of hematopoietic stem cells from human pluripotent stem cells [1]. At iPS Cell Research and Application (CiRA) based at Kyoto University, my research program focuses on understanding molecular mechanisms of human developmental hematopoiesis. My career goal is to contribute to regenerative medicine by bridging expertise in human developmental hematopoiesis and pluripotent stem cells.

Abstract

Despite rapid technological progress, the discovery of novel antibiotics has been stalled for the past 50 years. To combat the growing burden of antibiotic resistance, innovative drug discovery paradigms are required to improve and expedite the antibiotic discovery process. A crucial bottleneck in drug discovery is the identification of compounds’ Mode of Action (MoA). To address this problem we developed a rapid and systematic metabolome profiling strategy to classify the MoA of bioactive compounds. In contrast to existing methods based on phenotypic drug profiling, mostly on the basis of growth assays, we exploit here the intracellular response of about 1000 metabolites as a truly multiparametric readout of the cellular response. The specific advance over existing metabolic platforms is a faster throughput of 1-2 orders of magnitude, allowing our combined MS-based metabolomics and computational workflow to scale with the size of typical compound libraries. I will illustrate how this technology enables monitoring the metabolic response of Escherichia coli to 1279 human targeted drugs and revealed an unexpectedly large spectrum of metabolic effects in E. coli. Combining metabolic profiling with chemogenomic data, we predicted drug MoAs and epistatic drug interactions. Our approach opens new opportunity in systems pharmacology and reveals new ways to expand the search for new antimicrobial treatments to compounds with no growth-inhibitory activity (keywords: Metabolomics, Antibiotics, Drug Mode of Action).

Biography
Mattia Zampieri is a junior PI at the Institute of Molecular Systems Biology of ETH in Zurich. He studied Bioengineering in Padova before doing a PhD in Bioinformatics at the International School for Advanced Studies in Trieste and Boston University. During his PhD he worked on mathematical modeling of microbial metabolism and reverse engineering transcriptional regulatory network from molecular profiling data. In 2011 he moved to the lab of Prof. Uwe Sauer at ETH where he developed novel high throughput metabolomics frameworks and quantitative models to study the role of microbial metabolism in mediating the response to antimicrobial treatments. His research led to unique high-throughput metabolomics frameworks and computational tools broadly applicable to diverse biological systems and therapeutic areas, opening new opportunities in systems biology and systems pharmacology

Multiplexed genome engineering by Cas12a and CRISPR arrays encoded on single transcripts

On the 14th of November 2019 Carlo Cosimo Campa, ETH Zurich, will give a seminar entitled Multiplexed genome engineering by Cas12a and CRISPR arrays encoded on single transcripts at 5.00 pm in the College lecture theatre (Collegio a Volta).  All students are invited to attend, especially those reading Medicine, Biology, Biotechnology and Pharmaceutical Sciences. The poster of the lecture can be downloaded here.

Abstract

The ability to modify multiple genetic elements simultaneously would help to elucidate and control the gene interactions and networks underlying complex cellular functions. However, current genome engineering technologies are limited in both the number and the type of perturbations that can be performed simultaneously. Here, we demonstrate that both Cas12a and a clustered regularly interspaced short palindromic repeat (CRISPR) array can be encoded in a single transcript by adding a stabilizer tertiary RNA structure. By leveraging this system, we illustrate constitutive, conditional, inducible, orthogonal and multiplexed genome engineering of endogenous targets using up to 25 individual CRISPR RNAs delivered on a single plasmid. Our method provides a powerful platform to investigate and orchestrate the sophisticated genetic programs underlying complex cell behaviours.

Biography
Carlo Campa has a background in industrial biotechnology (B.Sc. and M.Sc. – University of Turin). He started his PhD studies at the PI3Ks Signalling Laboratory of University of Turin (Prof. Emilio Hirsch). For his postdoc, he moved to ETH Zurich at the Laboratory of Biological Engineering (Prof. Randall J. Platt – ETH Zurich) where his research activities are focused on the development of novel genome engineering tools. He has provided seminal contributions in the characterization of membrane dynamics and lipid signalling in embryogenesis and immunity (Developmental Cell 2014, Science Signalling, 2016, J. Immunol. 2013). Together with Kither Biotech s.r.l. he developed and exploited inhibition of lipid signalling to treat chronical airway diseases (Nature Communication 2018). He demonstrated the role of endosomes as a signalling platform in embryo development, and insulin resistance (Developmental Cell 2014, Nature Communication 2015). He defined that temporal control of signalling events provides a strategy to govern stochastic egression of neutrophils from the bone marrow (Science Signalling, 2016). He realized the first class of biosensors able to detect signalling events on endosome membrane microdomains and he provided the evidence that activation of endosomal signalling enables receptors exit from endosomes (Nature Chem. Biol 2018). Recently, he assessed the scaffold function of a lipid kinase in cancer resistance (Cancer Cell 2017) and I generated new genome editing tools for fast rewiring of complex pathways in cells (Nature Methods, 2019). By conducting investigations at the interface between biology, mathematics and engineering, he has aimed at defining both the design principles and the molecular mechanisms by which cells make decisions.
