The advent of super-resolution microscopy has created unprecedented opportunities to study the mammalian central nervous system, which is dominated by anatomical structures whose nanoscale dimensions critically influence their biophysical properties. I will present our recent methodological advances 1) to analyze dendritic spines in the hippocampus in vivo and 2) to visualize the extracellular space (ECS) of the brain. Using a two-photon–STED microscope equipped with a long working distance objective and ‘hippocampal window’ to reach this deeply embedded structure, we measured the density and turnover of spines on CA1 pyramidal neurons. Spine density was two times higher than reported by conventional two-photon microscopy; around 40% of all spines turned over within 4 days. A combination of 3D-STED microscopy and fluorescent labeling of the extracellular fluid allows super-resolution shadow imaging (SUSHI) of the ECS in living brain slices. SUSHI enables quantitative analyses of ECS structure and produces sharp negative images of all cellular structures, providing an unbiased view of unlabeled brain cells in live tissue.

Dr Katherine Wheelhouse did her MChem at Jesus College, Oxford, working in the chemistry department with Prof Tim Donohoe before joining GSK as a process chemist in 2008. Since 2011 Katherine has specialised in application of chemical catalysis to pharmaceutical manufacture. She is a GSK scientific fellow, a member of the RSC Applied Catalysis Committee and also of the editorial advisory board of the journal Organic Process Research and Development. Katherine is going to talk about what it is that process chemists do (to enable doing things bigger) and how this fits into the development of medicines, illustrating with some examples from recent projects.

The talk is free for OUSS members, or £2 on the door. Membership can be obtained on the night or on our website. Those interested in meeting the speaker for dinner after the talk may contact oxforduniscisoc@gmail.com. eng

Warburg Memorial Lecture – Joint with BBOWT
Bryophytes in Cambridgeshire have been recorded continuously since 1927 and with increasing intensity in recent decades. A detailed analysis of the records reveals the remarkably dynamic nature of the bryophyte flora of lowland England.

‘Triboreacted materials as functional interfaces in internal combustion engines and medical implants’

Reducing CO2 and particulate emissions to halt global warming and improve the air cleanliness in developed and developing nations is urgent. A similarly large challenge is the provision of medical implants that will serve the ageing population. Both challenges are underpinned by the need to understand important functional interfaces.
This talk will focus on the engine and the hip and will present how an understanding of the interactions between tribology and chemistry/corrosion play a crucial role in the interfacial friction, wear and integrity. The integration of state-of-the-art surface science with engineering simulations in both of these areas enables engineers to create optimised systems with improved performance

Newspapers often feature studies that sound too good to be true and often they aren’t – they are myths.

Some myths may be harmless but the phenomenon affects most kinds of research within evidence-based science. The good news is that there’s a new movement tackling misleading and unreliable research and instead trying to give us results that we can trust.

Using his research in to human pheromones as an example, Tristram will discuss how and why popular myths, including power-posing, are created and how efforts have been made to address the ‘reproducibility crisis’.

Tristram Wyatt is an emeritus fellow of Kellogg College, Oxford and formerly Director of Studies in Biology at OUDCE. He is currently a Senior Research Fellow at the Department of Zoology, University of Oxford. He’s interested in how animals of all kinds use pheromones to communicate by smell. His Cambridge University Press book on pheromones and animal behaviour won the Royal Society of Biology’s prize for the Best Postgraduate Textbook in 2014. His TED talk on human pheromones has been viewed over a million times. His book Animal behaviour: A Very Short Introduction was published by Oxford University Press in 2017.

Open to all. The talk is designed for researchers from all disciplines and is open to the public.

In mammals the cell-autonomous circadian clock pivots around a transcriptional/post-translational feedback loop. However, we remain largely ignorant of the critical molecular, cell biological, and circuit-level processes that determine the precision and robustness of circadian rhythms: what keeps them on track, and what determines their period, which varies by less than 5 minutes over 24 hours? The origin of this precision and robustness is the suprachiasmatic nucleus (SCN) of the basal hypothalamus, the principal circadian pacemaker of the brain. The SCN sits atop a circadian hierarchy that sustains and synchronises the innumerable cell-autonomous clocks of all major organs to solar time (and thereby to each other), by virtue of direct retinal innervation that entrains the transcriptional oscillator of the 20,000 or so component cells of the SCN. I shall describe real-time imaging approaches to monitor circadian cycles of gene expression and cellular function in the SCN, and intersectional genetic and pharmacological explorations of the cell-autonomous and circuit-level mechanisms of circadian timekeeping. A particular focus will be on “translational switching” approaches to controlling clock function and the surprising discovery of a central role for SCN astrocytes in controlling circadian behaviour.

The day will consist of a range of events, hosted by speakers from different areas of STEM and industry. Expect to hear from keynote speakers, engage with panel discussions, and get hands on experience in smaller workshops focusing on entrepreneurship, outreach, disabilities and more.

Don’t miss out on hearing from a range of speakers, including: Dr. Chonnettia Jones, Director of Insight and Analysis at the Wellcome Trust; Prof. Daniela Bortoletto, Professor of Physics at Brasenose; plus Oxford’s own Vice Chancellor, Louise Richardson.

Everyone is welcome, regardless of gender, year and subject.

Automation, AI and robotics are changing our lives quickly – but digital disruption goes much further than we realise.

In this talk, Richard Baldwin, one of the world’s leading globalisation experts, will explain that exponential growth in computing, transmission and storage capacities is also creating a new form of ‘virtual’ globalisation that could undermine the foundations of middle-class prosperity in the West.

This book talk will be followed by a drinks reception and book signing, all welcome.

In 2013, Carl Frey and Michael Osborne published a paper titled ‘The Future of Employment: How Susceptible Are Jobs to Computerisation?’ which estimated that 47% of jobs in the US are at risk of automation.

In this talk Dr Carl Benedikt Frey, Co-Director of the Oxford Martin Programme on Technology and Employment, will discuss the societal consequences of the accelerating pace of automation, and what we can learn from previous episodes of worker-replacing technological change.

This is a joint lecture with The Rockefeller Foundation Economic Council on Planetary Health at the Oxford Martin School

Cooling is critical for many of the sustainable development goals, including those relating to health, shelter, livelihoods, education and nutrition. As the world’s population grows, as disposable incomes grow and as urban areas grow, the need for cooling is booming. However cooling uses super polluting gases and large amounts of energy and is therefore a significant cause of climate change. More efficient, clean cooling has the potential to avoid up to a degree of warming by the end of the century and recently all governments came together to agree action to try to maximize this opportunity. Cooling sits at the intersection of the UNFCCC, the SDGs and the Montreal Protocol, but can these forces ensure success?

Dan Hamza-Goodacre will explain the risks and possibilities in the search for sustainable cooling for all.

Currently limited tools exist to accurately forecast the complex nature of disease spread across the globe. Dr Moritz Kraemer will talk about the dynamic global maps being built, at 5km resolution, to predict the invasion of new organisms under climate change conditions and continued unplanned urbanisation.

Dung beetles in the British Isles are a vital part of their associated ecosystems but have been historically rather overlooked probably due to their chosen habitat. Now our native dung beetles are finally beginning to get some of the invertebrate limelight due to an emphasis on ecosystem services and a much more environmentally friendly farming future. However we are lacking on a great deal of base data about these vitally important species and surveying is the one of the best ways to get information. This means getting into dung and discovering these unsung heroes

Carlos Lopes will deliver an overview of the critical development issues facing the African continent today. He will talk about a blueprint of policies to address issues, and an intense, heartfelt meditation on the meaning of economic development in the age of democratic doubts, identity crises, global fears and threatening issues of sustainability.

This talk will be followed by a book signing and drinks reception, all welcome.

The ecology and history of one of the largest atolls in the world. Aldabra, situated in the South West Indian Ocean, supports the largest population of giant tortoises worldwide. A UNESCO World Heritage Site, it is a stronghold for wildlife in a region that is besieged by threats.

Professor Dave Carter reveals how understanding intercellular communication could improve healthcare.

This is a joint event with the Oxford Martin Programme on the Future of Food

Dr Mike Hamm will explore the opportunity for regional food systems in-and-around cities for mutual benefit. He will approach a number of issues – including vertical farming, bio-geochemical cycles, water use, new entry farmers, and healthy food provisioning – embedded in the notion of city region food systems with reference to supply/demand dynamics.

In Origin of Species, Charles Darwin described how a population explosion occurs and called the time of population explosion “ favourable seasons”, he was not to know it, but such circumstances arose for his own species at around the time of his own birth. However, the favourable seasons for human population growth were not experienced favourably, with times of great social dislocation from small scale enclosure to global colonisation. Now those seasons are over, we have experienced the first ever sustained slowdown in the rate of global human population growth. This has been the case for at least one human generation. However, we are not just slowing down in terms of how many children we have, but in almost everything else we do, other than in the rise in global temperatures that we are recording and that we have to live with. It can be argued that there is even a slowdown in such unexpected areas as debt, publishing, and in the total amount useful information being produced.

If this is true – that humanity is slowing down in almost everything that we do – what does this mean? What measurements suggest that slowdown is true? And if so much is still rising, albeit at slower and slower rates – is that such a great change? Finally how might the slowdown impact on economic thought. In many ways economics was the science of the great acceleration; a science that makes most sense when markets are expanding and demand is rising. What kind of an economics is needed in a world where enormous and accelerating growth has stopped being the normality?

Our wild bees and other pollinators are so important, but they are still the unsung heroes of the environment, gardens and countryside and continue to decline in number and range. The talk will identify what we can all do to help wild bees. Many of the actions we take to protect one pollinator species, such as flower rich habitat creation and reduction in pesticide use, will assist biodiversity as a whole.

The high seas are under severe pressure from both direct and indirect human impacts, including the effects of over-fishing, plastic debris and climate change. In this talk, Prof Alex Rogers will present what a network of marine protected areas in the high seas might look like, protecting 30% of known conservation features and taking into account climate change impacts. We will also hear from Dr Gwilym Rowlands, who will consider how such a network of marine protected areas could be enforced and the potential benefits to the ocean.

Professor Sir Paul Collier and Professor Colin Mayer CBE will share the latest thinking and research into the future of capitalism and the corporation to understand how business might be changed to make it work better for society. The speakers will bring together their new books, The Future of Capitalism: Facing The New Anxieties and Prosperity: Better Business Makes the Greater Good, alongside the British Academy’s Future of the Corporation programme research to pose serious questions of our economic system.

This talk will be followed by a drinks reception, book sale and signing, all welcome

Now that Trump has turned the United States into a global climate outcast, will China take the lead in saving our planet from environmental catastrophe? Many signs point to yes. China, the world’s largest carbon emitter, is leading a global clean energy revolution, phasing out coal consumption and leading the development of a global system of green finance.

But as leading China environmental expert and author of Will China Save the Planet? Barbara Finamore will explain in this talk, it is anything but easy. The fundamental economic and political challenges that China faces in addressing its domestic environmental crisis threaten to derail its low-carbon energy transition. Yet there is reason for hope. China’s leaders understand that transforming the world’s second largest economy from one dependent on highly polluting heavy industry to one focused on clean energy, services and innovation is essential, not only to the future of the planet, but to China’s own prosperity.

We will also hear from respondent Radhika Khosla, Research Director at the Oxford India Centre for Sustainable Development, Somerville College.

The biosphere and econosphere are deeply interlinked and both are in crisis. Industrial, fossil-fuel based capitalism delivered major increases in living standards from the mid-18th through late-20th centuries, but at the cost of widespread ecosystem destruction, planetary climate change, and a variety of economic injustices. Furthermore, over the past 40 years, the gains of growth have flowed almost exclusively to the top 10%, fuelling populist anger across many countries, endangering both democracy and global action on climate change.

This talk will argue that underlying the current dominant model of capitalism are a set of theories and ideologies that are outdated, unscientific, and morally unsound. New foundations can be built from modern understandings of human behaviour, complex systems science, and broad moral principles. By changing the ideologies, narratives, and memes that govern our economic system, we can create the political space required for the policies and actions required to rapidly transform to a sustainable and just economic system.

The ability to accurately identify and interpret Track and Sign rests on a body of traditional knowledge that previous generations of naturalists would have regarded as fundamental. Sadly, now it is largely unknown and untaught, but with the upsurge of Citizen Science, it is perhaps more relevant than ever.

Crocodiles once roamed the Arctic, during the Eocene about 50 million years ago. Polar regions were lush and warm. Greenhouse gas concentrations were higher than today, but at most about 4 times higher – not enough, according to current climate models, to have warmed the Arctic sufficiently. Something appears to be missing in current models to account for the warmth of the past.

The likely culprits are clouds, especially the low clouds that cover vast areas of tropical oceans. These clouds cool Earth by reflecting sunlight back to space. It is possible that the cloud cooling may have been absent or strongly diminished in past greenhouse climates, raising questions about our climate future. To predict our climate future more accurately, breakthroughs in the modeling of clouds and in the accuracy of climate predictions are needed. They are now within reach, thanks to advances in computing and Earth observations from space and our ability to fuse models with massive amounts of data.
