On World Alzheimer's Day (21 September), Oxford scientists are beginning a new study in the battle to beat the increasing issue of dementia.

Dementia is a truly global issue and to tackle it, we need a joined-up approach. Oxford is leading the way in dementia research and this funding will help us to continue to make progress for all those affected.

Charity Alzheimer's Research UK, the UK’s leading dementia research charity, have increased their support for Oxford dementia research with two awards. One will support the community of dementia researchers in Oxford to work together towards the goal of defeating dementia. The second award will allow a team to study whether taking aspirin and omega-3 fish oils can improve people's memory and thinking skills.

Dementia is one of the greatest challenges facing modern medicine and there are currently 850,000 people in the UK living with dementia. For example, Oxfordshire alone has more than 8,000 people with dementia.

In the first ever project awarded by Alzheimer's Research UK's Global Clinical Trials Fund, Professor Jane Armitage at the University of Oxford will study whether aspirin or omega-3 fish oils have an effect on memory and thinking skills in people with diabetes. As an add-on to an existing clinical trial called ASCEND, funded by the British Heart Foundation, Prof Armitage and her team will test the memory and thinking skills in around 10,000 people who have taken aspirin, omega-3 fish oils or a placebo for 6.5 years.

Having poor heart health is associated with an increased risk of dementia, and diabetes is a risk factor for both heart health and dementia. Both aspirin and omega-3 fish oils are thought to reduce complications resulting from poor heart health, such as heart attacks and stroke, but previous studies looking at their effects on memory and thinking have been too small to detect what may be small but worthwhile benefits.

We are beginning to unravel the links between cardiovascular health, diabetes and dementia, and this trial will provide important insight into this relationship.

Prof Jane Armitage explains: 'We are beginning to unravel the links between cardiovascular health, diabetes and dementia, and this trial will provide important insight into this relationship. This is an excellent opportunity to study an existing group of around 10,000 people who have been taking aspirin or omega-3 fish oils for 6.5 years and examine the effects on their memory and thinking skills. Although these drugs are not being investigated for their potential to treat dementia, if they are found to reduce the risk of developing the condition then this could be of significant benefit in supporting healthy ageing.'

Oxford is home to the Alzheimer's Research UK Oxford Research Network Centre. The charity’s Research Network is the largest community of dementia researchers in the UK, with over 1,000 members across 15 virtual Research Centres. Being part of the Network provides researchers with unique access to funding for small grants to support travel, equipment and networking.

Prof Richard Wade-Martins, Coordinator of the Oxford Network Centre, welcomed the new funding. He said: 'We are delighted that Alzheimer's Research UK has continued to support pioneering research in the city. Being part of a UK-wide Network of dementia researchers is a real boost to us, enabling us to collaborate with other scientists and explore new avenues of research. Dementia is a truly global issue and to tackle it, we need a joined-up approach. Oxford is leading the way in dementia research and this funding will help us to continue to make progress for all those affected.'

Dr Rosa Sancho, Head of Research at Alzheimer's Research UK, said: 'We are dedicated to funding the best minds and forging the most effective partnerships, and so are very glad to be supporting the vital work of scientists in Oxford. There is currently no way to prevent dementia, and so research into the factors that affect a person’s risk of the condition is crucial if we are to help people achieve a better quality of life for longer. Dr Armitage has a wealth of experience of clinical trials relating to diabetes and cardiovascular disease, and it’s fantastic that she is now applying her skills to addressing important questions in dementia research.

'We know that we will not defeat dementia in isolation, which is why initiatives such as the Research Network are crucial to support researchers at a grass-roots level. Sharing of ideas and resources will spur scientists on to think more ambitiously and help us progress faster towards our goal.'

An Oxford University professor will be taking Radio 4 listeners on a journey through the history of the concept of infinity for the next fortnight.

Philosopher Professor Adrian Moore will present a 15-minute programme at 1.45pm from Monday to Friday this week and Monday to Friday next week.

In today’s episode of A History of the Infinite, Professor Moore explores why the idea of infinity made the Ancient Greeks so uncomfortable.

Oxford University academics contributing to the programmes include Ursula Coope, Professor of Ancient Philosophy, Cecilia Trifogli, Lecturer in Medieval Philosophy, and Professor Richard Sorabji, Honorary Fellow of Wolfson College.

Professor Moore says: 'This series is based on my book The Infinite (Routledge, 2nd edn 2001).  The first four programmes are concerned with the remarkable turnaround between the time of the early Greeks, when various puzzles and paradoxes associated with the infinite had made it an object of abhorrence and distrust, to the early modern period, by which time it had come to be associated with the divine and had become an object of veneration and awe. 

'In the next three programmes listeners are introduced to some of the extraordinary mathematical results concerning the infinite, including the discovery that some infinities are bigger than others. 

'In the final three programmes attention shifts to the cosmos and our place in it. I consider questions about the age and size of the universe, about death and immortality, and about our basic urge to seek meaning for our lives in something infinitely greater than us.'

All programmes will be available to listen to or download from the BBC website over the next month.

Many academics have recently come back to Oxford after a summer holiday. But Professor Liz Frood’s return to work (part-time) as Professor of Egyptology last week is a much more remarkable story.

Professor Frood contracted sepsis in August 2015. Her cousin Jane Wynyard picks up the story: ‘She spent ten days in the ICU, five months in hospital, had her legs amputated below the knees, lost her hearing in one ear, her nose collapsed and her hands were damaged almost beyond repair,’ she says.

This left Professor Frood severely disabled, with both legs amputated, no dexterity in my hands, partial deafness, and a reconstructed nose.

Miss Wynyard adds: 'Before Liz’s illness, none of our family had ever heard of sepsis or understood the life-changing and devastating effects this terrible infection could have.

‘In just one year, Liz has totally inspired and humbled us with her amazing will to survive and courageous battle to live a normal life despite her terrible injuries. Her bravery and determination have been matched by the incredible work of the NHS staff, doctors, surgeons and specialists whom we will always be indebted to for saving Liz.’

Some of Professor Frood’s family and friends set off today (Friday 9 September) on a bike ride beginning at the Ashmolean Museum and due to end in Cardiff. They are due to arrive in Gloucester this evening after completing the arduous first stage of their trip.

‘It’s been brilliant so far,’ Professor Frood reports. ‘We had a great send-off! The cyclists have been riding through gorgeous countryside, which seems to have them all very excited.’

The team, called the Dons of Oxford, hopes to raise awareness of sepsis and to raise money for the UK Sepsis Trust. They would welcome donations here.

A little over a year ago, Professor David Macdonald of Oxford University's Wildlife Conservation Research Unit (WildCRU) spoke of his desire to harness the global interest in the killing of Cecil the lion, creating a movement rather than simply a moment.

That journey continues this week with the Cecil Summit, a workshop held in Oxford that will bring together leading figures from across the world to consider future initiatives to preserve the African lion.

The summit will culminate in a free public event on Wednesday 7 September at the Blavatnik School of Government in which anyone interested in conservation will be able to hear the thoughts of top lion experts, as well as a variety of innovative thinkers from fields as diverse as economics, development, international relations and ethics.

The discussion, to be introduced with an illustrated talk by Professor Macdonald, will be chaired by Alan Rusbridger, Principal of Lady Margaret Hall, Oxford and former editor of The Guardian. It will take place from 5pm to 7pm. The summit follows more than a year of sustained interest in the story of Cecil, who was killed by a big game hunter outside Hwange National Park, Zimbabwe on 2 July 2015. Researchers from WildCRU were studying and tracking Cecil and his pride as part of their lion conservation research.

Professor Macdonald, the founding Director of WildCRU, explained the context for the summit: 'Lions, arguably the most iconic species in the world, are doing badly. That understatement captures the shocking fact that wild lions nowadays roam in only 8% of their historic range. Last year, researchers from WildCRU and Panthera, the big cat charity based in New York, published the finding that whereas a hundred years ago it is widely thought there were about 200,000 lions, today there are closer to 20,000.

'Against this distressing but widely ignored background, suddenly everything changed with the killing of Cecil, a fascinating elderly male Zimbabwean lion that WildCRU had been satellite tracking since 2008. Cecil's death prompted unprecedented media interest globally, and so with the world's attention focused on lions, WildCRU and Panthera resolved to hold the Cecil Summit with the purpose of asking whether the morbid trajectory of the lion's fate could be reversed, breaking the mould of conservation by seeking new, innovative approaches from beyond the realms of dedicated field biologists.'

The summit is a joint venture between Oxford and Panthera, whose President Luke Hunter said: 'The tragedy of Cecil's death spurred a unique sea change moment for global awareness of the lion's precarious state. But over a year later, the species is still in freefall in many places. The lion is running out of time.

'We hope that the Cecil Summit's brain trust of conservationists and innovators can spur a new infusion of support for African governments and people working to save the magnificent African lion.'

Speaking from WildCRU's centre at Tubney House near Oxford, Professor Macdonald said: 'In my experience, this summit is unique: we take 30 innovative minds, present them with a new problem, mix them with some conservation specialists, shake and stir, and hope for a breakthrough. It may work, it may not, but at least we will have tried. We'll have grasped the unique Cecil moment and challenged ourselves to find a new way ahead for the Cecil movement.

'Perhaps the unique feature of our approach, forcing inter-disciplinarity between those who know about lions and those who know about delivering high-level change to the human enterprise, will itself become a way ahead in conservation: the Tubney Format!'

He added: 'We believe that the more brains are involved the better, which is why we've arranged a public session in which Alan Rusbridger will lead a conversation with such guests as Rory Stewart, the UK's Minister for International Development; Achim Steiner, Director of the Oxford Martin School and recently head of the United Nations Environment Programme; Wilson Mutinhima, the Director General of Zimbabwe's National Parks; Craig Packer, the world's leading lion biologist; and Tom Kaplan, WildCRU's patron and the greatest benefactor in history to big cat conservation.'

The Cecil Summit's public event will take place at the Blavatnik School of Government from 5pm UK time on Wednesday 7 September. Attendance is free, but booking is required via the Oxford University website. The event will also be live-streamed on WildCRU's YouTube channel.

Oxford academics have teamed-up with an animator to bring ancient Greek vase scenes to life.

The images on this 2,500-year-old vase have been animated to show what life was like in ancient Greece.

The Classics in Communities project, which is led by Mai Musié of Oxford University to encourage the teaching of ancient languages like Latin and Greek, has teamed up with the Panoply Vase Animation Project following an award from the Oxford University Knowledge Exchange Fund.

The animation is freely available to watch online, and its creators hope it is used by teachers and lecturers to support their teaching of topics related to ancient Greece.

The video can be viewed here.

'Our animation features a cup that would once have been used at ancient drinking parties 2,500 years ago,' says Dr Sonya Nevin, co-director of the Panoply Vase Animation Project.

'The cup's decoration comes to life in the animation, with a scene of drinking, chatting, and playing music and games now acted out before your eyes.

'We hope it will be used by teachers, students and anyone else who has an interest in seeing classical history brought to life.'

The project is the latest initiative by Classics in Communities, a project involving Oxford University, the Iris Project, and Cambridge University.

'Our aim is to promote the teaching of Latin and Ancient Greek at state schools in the UK,' says founder Mai Musié of Oxford University’s Faculty of Classics.

'This animation is just the latest way in which we hope to engage teachers and students in these fascinating subjects.'
