A broken pot with a coin hoard spilling out

‘Digitisation is revolutionising research,’ says Professor Chris Howgego, Keeper of the Ashmolean Museum’s Heberden Coin Room, which celebrates its Centenary this year.

Along with colleagues from the Museum and the University, Professor Howgego is clearly very excited by the discoveries and new information which are expected to come from the digitisation of historic currency, currently underway at the Ashmolean and internationally.

Putting objects online is not just a nice-to-have, the Ashmolean’s curators insist, (although it is that). Digitisation is going to transform scholarship, adds Richard Ovenden, the head of Oxford’s Galleries, Libraries and Museums and the 25th incumbent as Bodley’s Librarian.

Digitisation is revolutionising research...Digitisation makes ‘big data’ research possible in the Humanities

Professor Chris Howgego

In terms of money, in particular, the implications could be far-reaching, Professor Howgego says. Not only will it will allow access to currently unseen objects – but more importantly it will also raise new questions and enable new methodologies, throwing a different light on past civilisations and societies, he explains.

With international collections and coin finds being put online, it will be possible for researchers to look in new ways at patterns of behaviour in the past and to work with other institutions to gain a much greater understanding of the ancient world. He says, ‘Digitisation makes ‘big data’ research possible in the Humanities.’

Although much focus on ancient coins comes from newspaper reports of sums raised, when finds are sold at auction, money provides a window into earlier cultures and societies. Professor Howgego’s enthusiasm for the subject is palpable.

If it were needed, the Ashmolean Museum’s 300,000 piece historic monetary collection, is proof positive that you cannot take it with you. It contains items from around the world, which have survived their owners by hundreds, if not thousands, of year. Made up of medals, bank notes and coins (some dating back to before 600 BC) the collection includes original Ming dynasty paper money, and some of the earliest coins ever minted, as well as golden hoards, buried in Oxfordshire, whose owners never returned to claim them.

It's history in your hand

Professor Howgego

The Ashmolean Museum’s 300,000 piece historic monetary collection is proof you cannot take it with you. It contains items from around the world, which have survived their owners by hundreds, if not thousands, of year

As crypto currencies around the world take a slide, leading many to question what is money, the Ashmolean team is in no doubt of the importance of the collection of which they are custodians.

‘It’s history in your hand,’ says Professor Howgego, of a coronation medal made for the accession of the boy King, Edward VI – and of a Roman gold coin thought to have been minted from gold looted from  the Temple in Jerusalem.

Clearly proud of the collection and the research taking place in Oxford, Professor Howgego reveals there has been a new (2,000-year-old) acquisition for the Ashmolean. It is an unparalleled collection of 1085 gold and silver coins of the Iceni (Boudicca’s tribe): some of these tiny, impossibly brilliant coins, astonishing survivors from late Iron-Age Britain are in a special display in the Money Gallery, shining two millennia after its owners were dead and buried. And these are just a fraction of the historic coins on display and in the Museum’s secure vault behind the scenes.

Oxford’s Ashmolean, the oldest public museum in the world, is home to one of the world’s leading collections of ancient money. It is a resource for academics and experts, increasingly globally, now the collection is being made available online.

Of the 300,000 items, a third have already been digitised, thanks to the efforts of volunteers in Oxford, says Dr Jerome Mairat, who expects to complete the digitisation of the Roman collection in the next few years.

The Ashmolean’s collection may be worth a fortune but, says curator Dr Shailendra Bhandare, its real value is as a record of the past. He explains, money has been made of metal, stone, shells, cloth and even rice – whatever is of value to the society. And the coins and notes tell much about the societies which created them, the development of the civilisations and trade – and war.

One of the ‘highlights of the collection, is the Oxford crown, struck during the English Civil War, in Oxford’s brief time as Charles I’s capital city. There are only about ten in existence, and two are in the Ashmolean. They were made in a mint in New Inn Hall Street.

Meanwhile, a new Roman emperor was discovered, found in hoard at Chalgrove, only 12 miles away.

‘They were dancing the conga at the British Museum when it was identified,’ recalls Professor Howgego. The curator who discovered it said it was so surprising that ‘It was like flicking through a pack of cards and finding an 11 of clubs.’

The coins themselves were often designed as records, rather than just being of monetary value, says Professor Howgego – used by rulers to put their stamp, quite literally, on history. From the images of short-lived Roman emperors, to pictures of Noah’s Ark, coins have been used to make statements – and not just in terms of the legality of tender.

The Coin Hoards of the Roman Empire Project, based in the Ashmolean, leads a collaborative international effort to preserve digitally this compelling form of national heritage. It has currently put online over 16,000 hoards containing a staggering eight million coins. The Roman coins that turn up today across Europe and Asia reveal the integrated nature of the Roman Empire – and its impact on neighbouring civilisations, such as India, where huge numbers of Roman coins have been found.  

Professor Andrew Meadows, a professor of Ancient History and a specialist in Greek coins, is anticipating considerable discoveries from digitisation and is leading a major study of Greek coinage.  He says, ‘Coinage became a world-wide phenomenon because of the Greeks...We’ll be mapping the Greek world through the coins [that are held in collections all over the world and are now online]...we’ll be looking at where coins come from and approximate figures for which places are heavily monetised and which are less so....it will enable us to understand what drove commerce in the first four or five centuries after coinage was invented.’

You couldn’t buy a loaf of bread with one of the coins...It could be worth a week’s earnings 

Professor Andrew Meadows

It is thought the earliest coins were created by rulers to pay soldiers to fight in wars

He says, we already know the first coins emerged in the Greek province of Lydia in what is now Turkey. But the coinage was not then, he explains, about facilitating trade and coins were not used by most people.

‘You couldn’t buy a loaf of bread with one of the coins,’ he says, holding a chunky gold piece. ‘It could be worth a week’s earnings.’

It is thought, he says, coins were created by rulers in order to pay soldiers to fight in wars, rather than to facilitate trade – although they did that as well.

Digitisation of ‘history in your hand’ is set to transform research.

How to use the science of the body clock to improve our sleep and health - Russell Foster, Professor of Circadian Neuroscience and the Head of Department of Ophthalmology

Jacqueline Pumphrey, April 2022

In his 1953 poem Days, Philip Larkin asks: ‘What are days for? Where can we live but days?’ He goes on with typical gloomy yet endearing angst: ‘Ah, solving that question/Brings the priest and the doctor/In their long coats/Running over the fields.’

Larkin would have done well to include ‘scientist’ along with priest and doctor. More specifically, he might have been interested to talk to circadian neuroscientists, such as Professor Russell Foster, who has said that the commercialisation of electric light since the 1950s has allowed us to ‘declare war upon the night’ and think that we can ‘do what we want, at whatever time we choose’.

Russell argues that in doing so, ‘we have thrown away an essential part of our biology’. One recent example of this can be found in Samsung’s ‘Night Owl’ television advertisement, which features a woman jogging through a city in the middle of the night (2.00am), tracking her progress with a Galaxy Watch. The advert encourages viewers to pursue their health and wellness goals on their own schedules – despite the overwhelming objective scientific evidence that this can be extremely harmful.

It is this insight about our arrogant 24/7 society that underpins Russell’s new book, Life Time, published by Penguin on 19 May. Almost a handbook, Life Time presents the reader with a wealth of information on what scientists have discovered about sleep and biological circadian rhythms. The book is designed to help each of us ‘make an informed and evidence-based decisions about improving our sleep and circadian health to improve our lives.’ Life Time represents a generous sharing of a lifetime’s work, and demonstrates Russell’s commitment to the public understanding of science.

Russell Foster is perhaps best known for his team’s contribution to the discovery in the late 1990s of photosensitive retinal ganglion cells, a type of neuron in the eye. Unlike the eye’s rod and cone cells, they’re not responsible for forming images, but for detecting light, providing information to the brain about the length of day and length of night. The ground-breaking discovery of these cells and their function was a milestone in the now exploding field of circadian biology to which Russell has dedicated his working life.

Photosensitive retinal ganglion cells are important because they help to ensure that the human body’s circadian system, which is organised by a master ‘body clock’ in the brain, is kept in synchronisation with external light and dark. Without this mechanism, our rhythms would drift out of sync, leading to all sorts of problems. We are biological animals whose organs need to be ready during the active phase of the day to eat and process food, and during the resting phase to use stored energy to repair tissue, remove toxins, fight off infection, form memories, and generate new ideas.

Russell’s interest in circadian rhythms is intertwined with his interest in the purpose and mechanisms of sleep, which led him to set up the Sir Jules Thorn Sleep and Circadian Neuroscience Institute at the University of Oxford in 2012. Scientists here are uncovering more about the fundamental ancient processes that govern time in our lives. They are investigating what happens when sleep and circadian rhythms are disrupted, for example in shift workers, or in those of us who think we can somehow live outside days, pushing our waking hours into the night. Being out of sync can lead to increased stress hormones, heart disease, weight abnormalities, reduced immunity, increased risk of cancer, and emotional and cognitive problems. No wonder Russell was motivated to share some of the cutting-edge insights from the scientific community in order to help people make good decisions about how to live healthy lives.

So what are the practical take-home messages of this book? Perhaps the most surprising one is that there is no ‘one size fits all’ in terms of sleep. It’s not helpful to think that everyone should be aiming for eight hours sleep a night, for example, or even that the holy grail is to sleep right through the night without waking up. The sleep that you need is linked to your genetics and environment and can change over the course of your life. The book includes pointers for how to determine your own ‘chronotype’ – do you function best in the morning, the evening, or in between? Armed with this information you can adapt your behaviour to synchronise your internal clock to external time in the best way for you.

There are specific messages about the best time for various health interventions: stroke medications such as aspirin should be taken before you go to sleep rather than in the morning, because aspirin turns-off the “stickiness” of platelets which are made at night; a flu vaccine is better given in the morning because the immune system is upregulated during the daytime. Russell explains the scientific evidence for behaviours that will improve our sleep, such as not drinking caffeinated drinks after lunchtime, and not eating a large meal or discussing potentially difficult issues immediately before bedtime.

The advice in this book is not delivered in a didactic fashion by an aloof expert from the hallowed halls of academia, but by an engaging and entertaining human being who is clearly excited by knowledge and passionate about sharing it. Academics are used to writing, spending long hours documenting the methodology and results of their experiments, and writing applications to persuade funding bodies to provide grants to allow that research to continue. But only a few are motivated or skilled enough to write about the insights of their work for the benefit of ordinary people who want to live their lives to the full.

Russell has clearly enjoyed digging deep into the topic that has fascinated him for his whole life, and then distilling the findings and making them accessible and relevant. His vast experience of giving public talks has enabled him to get inside the minds of his audience, and he has used genuine questions from people attending such events to form the basis of the wide-ranging and sometimes quirky Q&A sections at the end of each chapter. This book demonstrates the most practical purpose of the scientific endeavour – to apply the lessons learned in order to improve our everyday lives.

To return to Philip Larkin and what days are for, let us leave the answer to Russell, whose hope for his book is that it can help us to ‘be healthier, more creative, make better decisions, gain more from the company of others, and view the world and all that it has to offer with a greater sense of curiosity and wonder’.

Patient recruitment is on-track in the Oxford-led DeTACT trial of safe, effective drug combinations to prevent the spread of artemisinin and multi-drug resistant malaria in Africa.

The global fight against malaria is at a critical point. Overall progress has now stalled and even worsened in some countries in Africa, where most of the world’s 627,000 deaths from malaria occurred in 2020.

The situation is becoming grave with recent studies confirming the growing prevalence in Rwanda and Uganda of P. falciparum malaria parasites partially resistant to artemisinins, which are the most important frontline anti-malaria drugs.

No new antimalarial drugs are expected in the near future. If multi-drug resistant falciparum malaria becomes established in East Africa and spreads to other parts of Africa, it is soon likely to compromise the efficacy of artemisinin-based combination therapies or ACTs — putting millions of Africans at risk of drug-resistant malaria infection and death.

The WHO has said this 'independent emergence of artemisinin partial resistance in the African Region is of great global concern.'

One possible solution — new drug combinations with artemisinins and two other frequently used antimalarial drugs (Triple ACTs or TACTs) — was found in 2020 by the large multi-centre, multi-country TRAC2 study to be highly efficacious even in places where ACTs were failing.

Before TACTs could be widely deployed to control artemisinin-resistance in Africa, however, their efficacy, safety and tolerability would first need to be confirmed in African populations, especially children.

Led by University of Oxford-affiliated researchers based in Bangkok at the Mahidol-Oxford Tropical Medicine Research Unit (MORU), the Developing Triple Artemisinin-based Combination Therapies (DeTACT) trial is currently studying in eight African and three Asian countries two new TACTs to generate evidence that they are effective first-line malaria treatments and support their deployment in Africa to prevent or delay the emergence of artemisinin and multi-drug resistant malaria in Africa.

Funded by UKaid administered through the Foreign, Commonwealth and Development Office (FCDO), DeTACT’s goals are ambitious.

'The emergence of artemisinin resistance in Africa is a serious concern, and its containment is paramount to avoid treatment failures in falciparum malaria in the future. TACTs can be an important contribution to this, both by delaying antimalarial drug resistance to the existing drugs, and by providing an effective treatment for multidrug resistant infections. DeTACT will provide the necessary evidence on TACTs, deliver a product that can be deployed, and will engage with national and global policy makers and other stakeholders to discuss the potential position of TACTs in the mix of antimalarial drugs,' says Professor Arjen Dondorp, the Principal Investigator of the DeTACT.

Besides comparing two existing ACTs (artemether-lumefantrine and artesunate-mefloquine) against two TACTs constituted of one additional drug added to each of these combinations (amodiaquine and piperaquine, respectively), DeTACT is conducting studies to forecast the impact of TACTs on controlling the spread or emergence of multidrug-resistant falciparum malaria leading to its elimination, and to examine the market readiness and ethical considerations of using TACTs across the malaria endemic world.

'The DeTACT Project includes modelling studies that will project the impact and cost-effectiveness of TACTs in preventing the spread of artemisinin resistance, explained Dr Chanaki Amaratunga, DeTACT Project Coordinator.'

'We are also conducting studies with all malaria stakeholders, starting from patients to researchers and policy makers, to elucidate the ethical and market aspects of their deployment. Along with the clinical trial, these studies constitute a comprehensive assessment of the expected advantages and potential barriers to the large scale use of TACTs,' said Dr Amaratunga.

Despite disruptions caused by the COVID-19 pandemic, DeTACT has already recruited over 700 patients, and aims to complete the recruitment of close to 4000 patients by early 2023.

The modelling, ethics and market positioning studies are well advanced and are expected to be completed by the end of 2022.

In addition, MORU has signed a memorandum of understanding with Fosun Pharma and Medicines for Malaria Venture (MMV) to collaborate with them to develop and pre-qualify fixed-dose combinations of TACTs prior to marketing them across Africa and the malaria endemic world.

'The DeTACT Trial will generate data not only on the efficacy and safety of TACTs but also on the pharmacokinetics of each of the drug components, including in malnourished children – a particularly vulnerable sub-population. In addition, there will be cutting-edge analyses, combining clinical trial data with that from whole genome and transcriptome studies, to improve our understanding of artemisinin and other antimalarial drug resistance,' said DeTACT-Africa Coordinator Dr Mehul Dhorda.

'We sincerely thank our partners conducting the field trials for maintaining their commitment to completing the trial in a difficult context,' Dr Dhorda added.

DeTACT is the third of three FCDO-supported multi-country, multi-site trials (TRAC and TRAC2) that have characterised artemisinin resistance and tested multi-drug resistant malaria treatments in South-East Asia. The work related to pharmacokinetics of antimalarials in malnourished children is supported by a grant from the Wellcome Trust.

One trial. Over 47,000 participants. Nearly 200 hospital sites, across six countries. Ten results. Four effective COVID-19 treatments. And behind them all, an army of countless researchers, doctors, nurses, statisticians and supporting staff.

On the second anniversary of its official launch, the Randomised Evaluation of COVID-19 Therapy (RECOVERY) remains an exceptional study that is leading the global fight against COVID-19. The study is continuing to adapt to the changing dynamics of the pandemic, adding new promising candidate treatments, and launching in new countries with different population and healthcare systems.

It is likely that the true impact of RECOVERY can never be fully measured. But through discovering four treatments that effectively reduce deaths from COVID-19, it is certain that the study has saved thousands – if not millions – of lives worldwide. Crucially, low- and middle-income countries have shared these benefits, particularly since dexamethasone (the first treatment to be discovered) is inexpensive, easily administered and readily available in most hospitals.

The numbers are impressive, but each RECOVERY Trial participant has their own unique story, with many showing immense courage and altruism during one of the most difficult and frightening times of their life. As RECOVERY Trial participant John Hanna, who was put in an induced coma due to severe COVID-19, said: ‘Without the RECOVERY Trial, I don’t think I’d be here today, so I’m very grateful for all the work the team has done since the pandemic struck. I had minimum knowledge of clinical trials before COVID-19, but now I understand the important role these play, and that future studies will be needed to prepare the world for the next pandemic. Since taking part in the trial, I have become a member of the RECOVERY Trial’s Public Advisory Panel, and this gives me a feeling of involvement, belonging and pride to be contributing to something that has been so successful and continues to be.’

But the RECOVERY Trial’s impacts go far beyond saving lives and improving treatment of COVID-19 patients. Through pioneering a simplified, streamlined approach to running clinical trials, RECOVERY has redefined the speed at which life-saving results can be delivered. As Sir Martin Landray, Professor of Medicine and Epidemiology at Oxford Population Health, and Joint Chief Investigator for RECOVERY, said: ‘In 2019, I had no idea that I would be setting up a trial of treatments for an infectious disease, let alone a pandemic virus. I certainly would not have thought it possible to go from a blank piece of paper to enrolling the first patient in nine days, to finding the first life-saving treatment within ten weeks, and for it to be made standard NHS policy within three hours.’

Through integrating into routine care within NHS hospitals, RECOVERY has also shown the power of engaging front-line clinicians in research. Sir Martin Landray added: ‘For many doctors and nurses, their involvement with RECOVERY was their first experience of clinical research, and many have expressed an enthusiasm to continue. This experience could herald a new age for research, not just for this pandemic and the next but for other common infections such as influenza and chronic diseases.’

Dr Marion Mafham, Data Linkage Team Lead for RECOVERY, said: ‘RECOVERY brought clinical trials into everyday healthcare delivery, with frontline doctors and nurses consenting and enrolling participants directly at 177 hospitals across the UK. By integrating data from multiple sources, RECOVERY has produced rapid, reliable results improving outcomes in patients admitted to hospital with COVID-19. This required our team to use innovation and effective collaboration, identifying the right datasets, linking them to the trial participants and processing the data, while ensuring data security and quality - all whilst working remotely.’

Health and Social Care Secretary Sajid Javid said: 'Throughout the pandemic, the government has supported the UK’s world-leading research sector, with millions of pounds of funding for clinical trials into the most promising and innovative medicines. This includes around £2.1 million for the RECOVERY trial which has saved countless lives across the world.

'I am extremely grateful to the team at the University of Oxford – the brilliant work on RECOVERY has cemented the UK’s position as a global leader in identifying safe and effective treatments for Covid, helping the UK to live with this virus.

'I look forward to continuing to collaborate to identify more lifesaving treatments.'

For the wider public, the extensive media coverage of the study’s impacts has helped to increase awareness of the importance of clinical trial research, and the need for volunteers to take part in these. Meanwhile, beyond the UK it is hoped that the hospital sites participating in RECOVERY International will benefit from a long-term increased capacity for leading randomised controlled studies.

The RECOVERY Trial team extend their thanks to the many clinical staff who have made this trial possible, the thousands of patients who have taken part, and the funders for the study, particularly the National Institute for Health Research (NIHR)Wellcome, and UK Research and Innovation (UKRI).

Water is vital – not just for drinking and health, but for life chances and education.  Without water, how can you learn? And yet more than half a billion children around the world do not have access to basic water supplies in schools.

Today, on World Water Day, the REACH programme to improve water security for 10 million poor people in Africa and Asia is releasing an animated film to highlight the critical importance of water, climate and education in Kenya.

We all recognise the need for water for handwashing as well as for drinking, sanitation, food preparation and cleaning facilities. But water matters to educational outcomes. In many countries, providing reliable and safe water to schools is a challenge. Globally, an estimated 584 million children lack basic water in schools. In Africa, four in ten rural schools do not have access to basic water supplies.

We all recognise the need for water for handwashing as well as for drinking, sanitation, food preparation and cleaning facilities. But water matters to educational outcomes

Girls are particularly affected by insufficient water, especially if there are no facilities and water for menstrual hygiene.

Global evidence shows girls who complete secondary education are more likely to get better paid jobs, shape their family choices, and pass on these opportunities to their children compared to girls who drop out of school early. In Kenya, investments are being made to ensure water is available in rural schools by providing tanks for rainwater harvesting. This is a good option in areas where rainfall is reliable throughout the year.

But, in Kenya, rainfall patterns are increasingly unpredictable with many dry months. Rainwater tanks often do not last through dry periods, leaving schools with limited alternatives. Schools then face difficult choices depending on access to other water sources.

Oxford University researchers have supported the work of a local professional service provider, FundiFix Ltd, to guarantee repairs in water supplies in schools, clinics and communities water are fixed fast. Some 80,000 people benefit today from FundiFix’s work with future initiatives working to scale and sustain the benefits for millions more.
