250 years of weather in Oxford
Weather observations have been made at the Radcliffe Observatory in Oxford from 1772 to the present day; the longest continuous record in the British Isles and one of the longest in the world.
From the prolonged frosts of January 1776 to the record heat of July 2019, Stephen will celebrate this unique and priceless Georgian legacy by delving into the extremes and the quirks of British weather, using contemporary local photographs and expert analysis.
How were (and are) the records made? When was Oxford’s coldest winter? Its deepest flood? Has it ever snowed in summer? What do the records tell us about climate change?
Stephen Burt MSc FRMetS (Department of Meteorology, University of Reading- retired) is the co-author of Oxford Weather and Climate since 1767, published by Oxford University Press in June 2019. He has published more than 100 papers or articles on many and varied aspects of British climatology, including case studies of notable weather events such as the ‘Great Storm’ of October 1987, heatwaves, snowstorms and extreme rainfall. His previous books include The Weather Observer’s Handbook (Cambridge University Press) and joint authorship of One Hundred Years of Reading Weather (University of Reading). He is a Fellow of the Royal Meteorological Society, a member of the American Meteorological Society and the Scientific Instruments Society, and an Honorary Fellow of the University of Reading.

Fracking: behind the tabloid headlines
Jim will give a brief introduction to the history and development of fracking in the US and in the UK and use some US datasets to take a more detailed look at fracking, with details of some of the details of the minor earthquakes that have happened in the UK and how earthquakes are measured. He’ll consider the pros and cons of fracking in the UK energy context, how gas fits into this mix and how sources of gas are rapidly declining.
Wednesday 15th January 2020
For Chris, a recent trip to Uganda highlighted the rapid shrinkage of wildlife habitats, and particularly the effects on elephants living in formerly pristine environments. This throws the efforts of modern zoos in promoting conservation, education and research into the preservation of species to the forefront.
Zoos have evolved enormously since the 1960s, from dismal animal prisons into spectacular and encouraging enterprises that not only account for the natural behaviour of the species they maintain but also educate people about wildlife and its value.

Biological solutions for plastic recycling
The latest work of the Centre for Enzyme Innovation (CEI) reveals how an enzyme works to digest polyethylene terephthalate (PET), the main plastic used in single-use drinks bottles, clothing and carpets.
PET can take hundreds of years to break down in the natural environment and, together with other plastics, is causing a global pollution crisis. The CEI’s longer-term aim is to help to reduce the pollution in our oceans and the greenhouse gasses associated with current plastic production and disposal methods, such as incineration and landfill.

Carbon Net Zero Challenge
In the last 12 months climate change has catapulted to the forefront of the public mind. The reasons given for this have ranged from David Attenborough’s Blue Planet to the recent school strikes that garnered the support of millions across the world.
This huge public interest has required governments to at least state their current stance on the topic. The UK has led the way by announcing a carbon net zero target by 2050, while other countries have lagged behind.

Beacons of the past: citizen science and LiDAR; shedding light on the history of the Chilterns’ landscape
The results of the UK’s largest-ever archaeological LiDAR survey have recently been made publicly available to citizen scientists. The 1400 km2 survey, covering the Chilterns AONB and its surroundings, shows lumps and bumps across the landscape, some of which were formed by natural processes, some of which reflect modern activity, but many of which are archaeological: evidence of people living and working here, from the Neolithic to the twentieth century. The technique is particularly powerful in wooded landscapes, able to show topography beneath the tree canopy, where archaeological survey using ground-based or aerial methods has traditionally been very difficult. With more than 20% tree coverage, the Chilterns AONB has many secrets to reveal.
Wednesday 18th September
Battery material development
Climate change, the reduction of greenhouse gasses and air pollution in large cities are major drivers of the drastic transformations of our energy supply and consumption. Recent years have seen a significant increase in renewable energy supplies, amid ever-growing demand for energy. At the same time various factors are increasing pressure on the electricity grid network. Energy storage technologies offer great potential and will play an essential role in the transition to a fully-renewable energy supply. Further, the automotive sector plays a key role in reducing CO2 emissions and air pollution. The UK’s target to achieve net zero emission by 2050 means that almost every vehicle must be electrically powered.

Weather balloon measurements of the atmosphere: past, present and future
Since the late eighteenth century, scientists have been yearning to measure the atmosphere above them. The first pioneers put their lives at risk making measurements from hydrogen-filled balloons. Nowadays, the process is much safer; thousands of weather balloons take up sensor packages called radiosondes, small smartphone-sized instruments packages which send the information back to base over a radio link.

Fungi: that other kingdom
The fungi comprise a kingdom as diverse as animals and plants, are vital in the functioning of terrestrial ecosystems and sensitive environmental indicators, yet are comparatively neglected.
We still only know a fraction of their biodiversity. Although fungi are often portrayed in a negative way, their contribution to relationships, such as mycorrhiza, makes them central to the survival of plants and to human welfare.

ALBATROSS: a film
ALBATROSS, a film by artist Chris Jordan, is a powerfully moving work of love for the natural world.
On a remote atoll in the North Pacific Ocean, albatross chicks are dying, their bodies filled with plastic. ALBATROSS unflinchingly shows the horror and grief of this tragedy, but ultimately brings us to a deeply felt experience of beauty and love for life on Earth. Stepping outside traditional documentary film style, ALBATROSS delivers a profound message of reverence and renewal.

Dentistry – revolution or evolution?
Is dentistry undergoing a revolution or is it purely evolution? Traditional techniques and careers are being challenged by so-called ‘disruptive technologies’. Dentistry is not immune: we will explore some of the new digital technologies that are revolutionising dentistry, including 3D scanning that eliminates the need for those dreaded impressions
Wednesday 13th February 2019
Space Traffic Control
Whether we realise it or not, we now depend significantly on the satellites that orbit our planet. A number of hazards threaten our continued access to these valuable assets, including eruptions on the sun and the thousands of pieces of space junk that we’ve launched since 1957. Stuart will discuss what Space Traffic Control is and why it is so important.
Wednesday 16th January 2019
One Body , One Life!
Are you always stressed, constantly busy, prioritising others over yourself? Do you feel that time is slipping by and your health is not what it was? Do you recognise what is “good” and what is “bad” for your health? The solution: assess where you are now and then follow a series of easy, sustainable, changes that you can stick to, get the balance right, and reclaim your health. You only have One Body and One Life! Don’t Screw it Up!

Reinventing the wheel
Bronwen Percival and Francis Percival
In little more than a century, industrial mindsets have altered every aspect of the cheesemaking process, from the bodies of the animals that provide the milk, to the microbial strains that ferment it, to the methods used to make the cheese. What has been lost as raw-milk, single-farm cheeses have given way to homogeneous factory production?
Bronwen and Francis will discuss how scientists—and the most enterprising cheesemakers—have begun to explore the cheesemaking techniques of their great grandparents. Taking advantage of the latest high-throughput molecular methods, researchers have begun to challenge conventional wisdom about the role of microbes in every part of the world around us, and to reveal the resilience and complexity of the indigenous microbial consortia that contribute to the flavour and safety of cheese. Bit by bit, one experiment at a time, these dynamic communities of researchers and cheesefarmers are reinventing the wheel.

Tackling the silent killer on our streets
Ambient air pollution is harmful to human health from before birth to old age, contributing to approximately 34,000 early deaths in the UK each year. Improving air quality requires an interdisciplinary research approach to identify the most effective intervention measures which optimise health benefits. Suzanne will consider the contemporary challenge of air pollution including action we can all take to reduce toxic emissions.

Plant sciences research for 21st-century challenges
Population increases and climate change demand a rethink of the ways in which we produce our food. Jane will discuss why we need new approaches, what types of crops are needed, and how research in plant sciences can provide solutions.
Wednesday 20th June 2018
Neonicotinoids and bees
Neonicotinoids are one of the most widely used pesticides in the world. However, their frequent use on flowering crops (such as oilseed rape) has raised concerns over risks to honeybees and wild bees, as the chemical is often found in the pollen and nectar of crops that they feed on. While many studies have identified negative effects on honeybees and wild bees, they have often been criticised for not reflecting what we see under normal agricultural conditions. Ben will discuss the findings of the largest study undertaken under ‘real world’ conditions to assess the effects of neonicotinoids on bees and the implications of the use of these pesticides in the UK and Europe.
Wednesday 25th April
The viruses of blood-feeding insects and ticks
Anthony will discuss the biology of blood-feeding insects and ticks, how this affects the spread of the viruses they transmit and the likelihood that strategies for their control will succeed.

String theory – then and now
Is string theory bullshit or the one true theory? Joseph will describe string theory and the many evolutions it has taken since it was first formulated fifty years ago. Why do so many people work on a topic without direct empirical support?
Wednesday 17th January 2018
A slippery situation: melting ice in the polar regions
The media are full of reports of changes to the polar regions, from trillion-tonne icebergs breaking away in Antarctica, to melting sea ice. How much do we know about these changes and how worried should we be? Will they affect us?
Wednesday 6th December 2017
Hedgehogs: how far can they travel, where do they go, how long do they live and what are the current concerns about their apparent decline? Do they have fleas, how many are rescued each year and taken to animal hospitals and what happens to them after being released back into the wild? And do hedgehogs make good pets?
Wednesday 15th November 2017
Joint replacement technology
Steven will discuss the ins and outs of joint replacement surgeries and technology, including what is described as “the metal on metal fiasco”, hip resurfacing, ceramic joints, oxinium, and other materials. Are any of the new materials and ideas actually working? This is an area which merges medicine, material science, immunology and engineering. It’s a complex problem, and one which affects many families.
Wednesday 18th October 2017

The 100,000 Genome Project
Jen Whitfield & Jude Craft
The 100,000 Genomes Project — the largest national sequencing project of its kind in the world — aims to sequence the genomes of approximately 70,000 NHS patients living with rare diseases and cancer. Its goal is to create a new genomic medicine service in the NHS, transforming patient care and enabling research into the causes and treatment of genetic disease. For some patients, this will mean they can receive a genetic diagnosis, where that wasn’t previously possible; for others, particularly cancer patients, there is the potential for new personalised treatments.

What we cannot know
Café Scientifique Henley celebrated its 50th event in style at Gillotts School on Wednesday 1st February, with special guest Marcus du Sautoy , an ex-Gillotts School pupil who lived in Church Street and also went to Trinity School before going on to become Professor of Mathematics at Oxford University and now a Fellow of the Royal Society. A regular on both radio and television, he was warmly welcomed by the Head Teacher, Catherine Darnton, before he discussed his latest book What We Cannot Know, leading the audience on a thought-provoking expedition to the edges of modern science to see if there’s anything we truly cannot understand. Being an Arsenal supporter gave him an everyday example of things that cannot be explained but he still has faith in them winning the Premiership one day! More seriously, he spent time investigating the randomness of casino dice, of the uncertain depletion of uranium and displaying his array of amusing but educational toys. His interesting and entertaining talk gave everyone an evening to be treasured.

The role of the natural environment in future cities
Economics for the Environment Consultancy
Ian is one of three directors of the specialist consultancy, eftec, which works to identify, value and interpret how changes to the environment affect people. He first worked on the value of the natural environment for human health as an economist at the Royal Society for the Protection of Birds in 2004, and has since applied the growing evidence on the importance of green space in cities in a number of studies for the UK Government and European Commission. The natural environment is increasingly seen as a cost for urban authorities and developers, but should instead be regarded as a valuable asset, central to making future cities economically productive and desirable places to live.
Wednesday 16th November 2016
Adrian founded the Oxford Animal Flight Group in 1996. His research focusses on the aerodynamics and control of flying animals, trying to understand how animals (particularly insects) generate so much lift from such small wings and how they manage to cope with the high levels of turbulence in the cluttered environments they exploit. Recently that work has begun to be exploited in the design of bio-inspired vehicles by his Oxford University spinoff company, Animal Dynamics.

Simulating the performance of products using engineering software tools
Formula 1 cars need to be strong & stiff enough to perform properly and durable enough to last the race, but they also have to be light enough to be competitive when accelerating and cornering. David Reid, from the SIMULIA division, Dassault Systèmes works with companies across multiple industrial sectors, helping them to assess the performance of their products, long before they have been manufactured and even before a physical prototype has been made.

Understanding and coping with pain
How does ongoing pain, or a reduction in ongoing pain, change the brain? Why are some people able to cope with pain whilst others are unable to maintain normal functions? Our cognitive and biological mechanisms can make pain noticeable and individual differences in these mechanisms might underlie differences in how people cope and respond to treatment.

The singular origin of complex life
All complex life on Earth shares a common ancestor that arose just once in four billion years of evolution. That common ancestor had a large number of complex traits, from the nucleus to sex, none of which is known in bacteria. Nick argues that the common ancestor of complex life was a chimeric cell, in which a simple host cell engulfed a bacterium, the ancestor of mitochondria. This endosymbiosis changed the basic architecture of cells, ultimately giving them orders of magnitude more energy per gene. He will discuss the singularity of complex life: why mitochondria enabled the evolution of enormous genomic complexity, while simultaneously forcing the evolution of so many curious traits.
Wednesday 11th May 2016
The Origin of our Species
Human evolution can be divided into two main phases: a pre-human phase, in Africa, more than two million years ago, where walking upright had evolved but many other characteristics were still essentially ape-like; and a later human phase, when both brain size and behavioural complexity increased, and there was a major expansion of the population out of Africa.
The evidence points strongly to Africa as the major centre for the genetic, physical and behavioural origins of both ancient and modern humans, but new discoveries are prompting a rethink of some aspects of our evolutionary origins, including the likelihood of interbreeding between archaic (for example the Neanderthals) and modern humans.

The phenology of butterflies and moths
Butterflies and moths are amongst some of the most well-studied creatures in the UK. Over the past 40 years, butterfly population trends have been used in conservation management and as biodiversity indicators. As cold-blooded organisms, butterflies show strong responses to changes in temperature and the effects of climate change. Flight periods are no exception, with some species now being on the wing more than three weeks earlier than in the past.

Social class in the twenty-first century
What kind of social class divisions exist today? Mike will discuss how the old world, in which we used to distinguish between middle and working class, is changing rapidly, and that today we are seeing a much smaller wealthy elite class pulling away from the majority of people in the middle layers of the class system. He will discuss some of the worrying features of this trend, including growing age and generational divisions, intensifying geographical divisions, and the role of élite universities (notably Oxbridge and the colleges of the University of London) in reinforcing social inequalities.

Towards a therapy for retinal disease
Jörn Lakowski, Fight for Sight Investigator
Jörn will reveal some of the approaches being investigated to develop treatments for retinal dystrophies, focussing on cell therapy. He will describe both the current state of the art in stem cell systems and how they can be harnessed to produce donor cells for therapy. Jörn will discuss some examples of disease modelling, such as for drug screening and some of the non-scientific challenges to progress in this field.
Wednesday 20th January 2016
Erupting volcanoes of the East African Rift
The East African Rift is caused by the Earth’s crust pulling apart. As it does so, hot, deep rocks are drawn upwards and tend to melt, producing magma that powers volcanism along the Rift. This volcanism is distinctive, with some unusual characteristics. Geoff will discuss three volcanoes that have erupted in recent years: Dabbahu in Ethiopia, Oldoinyo Lengai in Tanzania and Nyamuragira/Nyiragongo in the Democratic Republic of Congo, and ask: could it happen in the UK?

Precipitation, snow and hazardous weather
Anthony Illingworth, Professor Emeritus of Atmospheric Physics at Reading University
Can we improve forecasts of hazardous weather – such as heavy rain that may cause flash floods, snow likely to disrupt traffic and strong winds that will bring down trees and block transport routes? How are the present forecasts produced? Will the new satellites to be launched in the next few years help to produce more specific detailed warnings? Finally we consider if severe weather events are becoming more frequent and if we will get snow for Christmas.

The perfect meal : the multisensory science of food and dining
Charles Spence, Experimental Psychologist, Oxford University
The author of The Perfect Meal examines the elements (taste,vision,hearing,touch and smell) that contribute to the diner’s experience of a meal (primarily at a restaurant) and investigate how each of the diner’s senses contributes to their overall multisensory experience.Driven by well known chefs such as Blumenthal and Carluccio, as well as young modernist chefs including molecular mixologists, novel approaches are needed to understand the diner’s experience in the restaurant setting from the perspectives of neuroscience, marketing, design, and psychology.

Fusion power: safe, clean and inexhaustible?
Fusion power – the power source that drives the sun and the stars – has the potential to solve all our energy needs for thousands of years, with minimal environmental impact. Thousands of scientists and engineers in many countries are working to realise it. In the process, they are building and using extraordinary machines that achieve conditions that stretch the imagination to the limit; for example, temperatures of 100 million degrees.

CO2: saint or sinner?
Carbon dioxide absorbs and reflects infra-red radiation, so it may be responsible for all the climate change we see today. An carbon dioxide levels ares increasing. But maybe it isn’t a died-in-the-wool villain; maybe it’s just misunderstood. You can use it for good too: with it, you can grow plants more quickly, sort out alkaline waste water or freeze hamburgers. You can even make ice cream with it!

Exploring the realm of the giants
Beyond the orbit of Mars, in the realm where water ice dominated the building blocks of our solar system, four enormous balls of hydrogen-helium gas coalesced from the proto-solar nebula. The four giant planets, grouped as the gas giants Jupiter and Saturn and the ice giants Uranus and Neptune, exhibit startling diversity in their environmental conditions and climate, despite the similarities in their origins. They serve as perfect templates for giant worlds being discovered around other stars, from the coldest ice giants to the hottest of exo-Jupiters. Given their great distance, missions to the giant planets are ambitious, complex and rare undertakings but our initial survey of the realm of the giants is complete and we’re beginning a detailed reconnaissance of these distant worlds.

The plight of the bumblebee
Bumblebees are icons of the British summer but they’re in trouble. Two of Britain’s 27 bumblebee species became extinct during the twentieth century; several more are thought to be on the brink, prompting the establishment in 2006 of the Bumblebee Conservation Trust. Often eclipsed by their domesticated cousin, the honeybee, bumblebees are misunderstood and under-studied but fascinating creatures.

The construction of Dorney Lake
Dorney Lake was constructed as the venue for the 2012 Olympic rowing and canoeing events. This 2.4km. long lake, with a return lane, is substantially wider than the adjacent River Thames and is surrounded by new parkland and nature reserves created after ten years of gravel extraction. Although the project, with its large boathouse, finish tower, car parking and roads is in the Green Belt and was refused permission by the planning authority, the Rowing Lake won the 2009 RTPI National Planning Award for Arts, Culture and Sport.

Alexander Parkes and the early days of plastics
Plastics are largely thought to be a twentieth-century phenomenon. However they have their roots in the nineteenth century – a time of enormous creativity and innovation in the field of new materials.
The story of Alexander Parkes, Parkesine, Celluloid and the birth of the plastics industry is a story with many twists and turns. The early pioneers had many setbacks and it was their successors who were to reap the financial rewards of the development of a global plastics industry.

Cosmic Quest – from Babylon to the Big Bang
Heather Couper and Nigel Henbest
Our glorious night sky is the ultimate landscape. But where do we fit in?
For thousands of years humankind has sought to find our place in the cosmos. Starting with superstition, astronomy has flourished, to become the most all-embracing of the sciences. Its progress has been led by inspirational characters – and outright mavericks! – who have pushed our knowledge of the heavens forward, forever testing the limits of our imagination in the quest to understand the Universe.

Extreme weather and climate change
Ray Bell, Department of Meteorology, University of Reading
What role does climate change play in the recent extreme weather in the UK and in other parts of the world? Coastal flooding and heavy rain this winter caused an estimated £1bn worth of damage. Typhoon Haiyan in November 2013, which was one of the strongest cyclones every observed, killed at least 6,300 people in the Philippines. How might extreme weather change in the future?

Friends in low places!
This cafe will offer an overview of the trillions and trillions of bacteria that inhabit the human gut. Glenn will describe who the bugs are, where they come from, how many there are inside the human body and how they handle our daily diet. He’ll describe the critical role of gut bacteria in promoting better health and suggest how our diet can help sustain them. He’ll also discuss the probiotics and prebiotics and their ability to alter the composition of gut bugs.
Wednesday 9th April 2014
Bubbles: the bath and beyond
Bubbles in liquids are a fascinating and important part of our everyday world, but we still associate them mostly with having baths. What do bubbles do and why are they important? It’s not all obvious – snails blow bubbles, penguins use them to go faster and there is a precise technical reason why bubbles are a champagne connoisseur’s best friend. My research is on bubbles formed by breaking waves in the ocean, and I’ll also talk about how we study bubbles in the ocean, and the difference that they make to weather and climate.
Wednesday 12th March 2014
The viruses in all of us
Did you know that all human genomes contain tens of thousands of viruses? Michael will describe some of his work into the oldest and newest viruses in our DNA and discuss a virus he and his colleagues identified which may have been the ancient origin of HIV. The timescales of paleovirology are enormous. This old virus first infected an ancestral mammal in the early Cretaceous period, some 130 million years ago, and even the newest viruses, some of which may cause certain cancers in humans, are several hundred thousand years old.

Light and the body clock
All life on Earth has evolved under a 24-hour cycle of light and darkness. As a result, virtually all organisms possess an internal ‘circadian’ clock that determines when to be active and when to sleep. What is the basis of these 24-hour rhythms and how do they regulate such a wide range of processes throughout the body? Moreover, how does light set this clock to the correct time and what are the consequences when the process goes wrong?

James Sowerby and the origin of meteorites
Professor of Mineralogy, University College London
James Sowerby was a remarkable natural historian during the Enlightenment: a fine artist, botanist, zoologist and even mineralogist. What special role did he play at the start of the proper scientific study of meteorites and their origins? And what have we learned, and are still learning, about meteorites and their impacts since then?

The ageing brain
“I’ve known her for fifteen years and her name has completely slipped my mind.”
Structural changes in our brain probably underlie such experiences. Like any organ or part of our body, the brain ages. This is healthy, normal, ageing and of course, if we use the brain, keep active and eat properly, we can minimise these effects. However, like any organ, there are many disorders of the brain in which the risk factor is age. These include Alzheimer’s disease and other dementias and Parkinson’s disease: all are associated with the death of specific types of brain cells. Although we cannot stop the death of the brain cells, in one case, Parkinson’s disease, we have a success story in terms of treatment.

Stem cells and the promise of regenerative medicine
Paul J Fairchild
If newspaper headlines were to be believed, stem cells promised treatments for a plethora of common ailments and diseases and yet, more than ten years after the first derivation of human embryonic stem cells, their impact on clinical medicine has yet to be realised. Furthermore, the use of stem cells has created an ethical quagmire that threatens to eclipse the legitimate benefits they may bring. So are we on the cusp of a revolution in medicine or is all the hype unjustified? Paul will attempt to delve beneath the rhetoric to distinguish fact from fiction and provide a realistic assessment of the future impact of stem cell biology on regenerative medicine.

Organic food and farming: global saviour or a case of the emperor’s new clothes?
How can the world’s farmers possibly produce enough food to satisfy the appetite of the ballooning global population, while not devastating the environment in the process?
