Dr Farragher was interviewed on BBC Radio Sussex about the Biology of Ageing recently. You can listen to what he had to say here.
It’s a debate that has been raging for years.
Scientists previously thought Rudolph’s red nose was due to an excess of blood in the vessels supplying the reindeer’s nasal passages, caused by the exertion of pulling a heavy load – Santa’s sleigh and his sacks of gifts.
Researchers here at the University of Brighton have found drugs used to treat mood disorders are also potentially active against bacteria which cause catheter infections.
The discovery could lead to new methods of treating infections and could contribute to overcoming problems with antibiotic resistance.
University of Brighton scientists have helped discover a way of regenerating ageing skin cells – with compounds based on those found in red wine, dark chocolate and red grapes.
Laboratory experiments showed cells not only look physically younger but behave more like young cells and start dividing.
Professor Richard Faragher, Professor of Biogerontology, and Dr Lizzy Ostler, Head of Chemistry, said the breakthrough should generate more research into tackling health issues associated with ageing.
Professor Faragher said: “These findings illustrate the enormous potential of ageing research to improve the quality of later life. Older people no more want to be sickly ‘frequent flyers’ with the NHS than teenagers do.
“A recent Government report recognised historic underinvestment in ageing research in the UK. I say to politicians of all parties: Redress this now and give our older people the healthy futures they deserve.”
Dr Ostler said: “Breakthroughs of this kind really need chemists and biologists working on research and teaching together under the same roof. We prize our multidisciplinary collaborative atmosphere at Brighton. This breakthrough vindicates that approach.”
The scientists, members of the University’s Stress, Ageing and Disease Centre of Research and Enterprise Excellence, worked together to select the best compounds for testing from a library designed and synthesised by Dr Vishal Birar, whilst he was undertaking a University of Brighton-funded PhD studentship under Dr Ostler’s supervision.

One of the UK’s leading experts on ageing is discussing whether science should help us live forever in a debate being streamed live around the world.
Professor Richard Faragher, Professor of Biogerontology here at Brighton, rejects the idea that the objective of ageing research should be the indefinite extension of human life. He argues: “This focus allows a selfish minority to misrepresent the altruistic goals of the scientific community.”
Professor Faragher is joining other eminent experts in Coruña, Spain for the debate on 7 November.
He believes there should be more investment in researching drugs and treatments to improve the quality of life in older age: “At a time when our capacity to translate new knowledge about the mechanisms of ageing into medicines and lifestyle advice is limited only by a chronic shortage of funds, older people are ill-served by self-indulgent science fiction.
“They need practical action to restore their health and they need it yesterday.”
The Professor’s comments come in the wake of recent discoveries he and his collaborator, Professor Lorna Harries of Exeter University, published recently on a new mechanism controlling ageing which they hope may prove amenable to treatment.
The debate will be conducted in Spanish and English, with simultaneous interpretation to and from each language. It has been organised by the University of Santiago de Compostela and is funded by the Spanish Foundation for Science and Technology of the Spanish Government’s Ministry of Economy and Competitiveness.

A University of Brighton experiment will test just how clever urban foxes really are.
BBC Two’s Autumnwatch, which starts Monday (Oct 23) at 8pm, will be featuring the testing which has been put together by the mammalian biologist , Dr Dawn Scott.
Dr Scott, Assistant Head of our School of Pharmacy and Biomolecular Sciences, said: “We are interested in how animals have adapted to urban habitats. Urban habitats are structurally complex environments with a wide range of food sources but sometimes those food are in difficult places to get to – so an animal that can solve problems quicker may do better in urban habitats.
“Urban environments also have lots of novel objects – if foxes are fearful they may not do as well in an urban environment as a fox that can quickly habituate to new objects.
“Our question is are foxes in urban areas less fearful and have a greater ability to solve problems than their rural counterparts?
“We can test this by looking at how animals respond to a new object in their garden. How close they come and how quickly they become habituate to it.
“This is a pilot study to see if we can set up an experiment to test, neophobia (fear of new things), intelligence and cognitive ability in foxes.”
The experiment will involve encouraging foxes to pull strings to retrieve food.
Dr Scott said: “If they can choose the right string in the experiment to pull the food out this will demonstrate their ability to solve problems. I expect the foxes will get better with experience.”

BSc (Hons) Biomedical Science
“Choosing to do a placement year at GlaxoSmithKline was one of the best choices I could’ve made during my degree. Spending a year working in the management of Phase II-IV clinical trials has given me so many opportunities to learn about the drug development process, and play a key role in the progression of new therapies in the Immunoinflammation, Neurosciences and Dermatology therapy area. I was able to experience a scientific career away from the lab bench, and the skills I’ve gained during this time will be completely invaluable when returning for final year and when applying for graduate jobs. I really couldn’t recommend applying for an industrial placement year enough!”
Anna Marie Lawn, third year BSc(Hons) Ecology student tells us about her time volunteering over the summer.
From July-September 2017, I volunteered with the organisation of the Society for the Protection of Turtles in Northern Cyprus, working with the native green and loggerhead sea turtle species.
There, I worked and lived for 6 weeks with 25 students, sharing mattresses laid out on the floor of a room and outside the building on some inhabitants setting quiet alarms as not to wake up others on different shifts, and all equally in our permanent state of being covered head to toe in sand from the previous day. In the day, we made lunch out of whatever was in the communal fridge (mostly pita bread and halloumi) with two students who had been blessed with a day off, cooking each night using whatever vegetables we could find for a low enough price at a nearby market.
Our work day rotated between night and day shifts, consisting of 10-15 hour days. Night workers patrolled protected beaches from 8:30pm-7am, asking people on the beach after hours to leave, and finding adult female sea turtles who we would observe laying eggs and marking out the locations with GPS co-ordinates. Adults would be flipper tagged, have their carapace measured length and width and have their behaviour recorded; all in the dark with only our faint red head torches shining.
Day work consisted of opening and closing ring cages (used to protect the turtles from crabs, foxes and dogs that people would illegally bring to the protected beach) these would be opened according to the time of day and heat of the sand, allowing any hatchlings to leave their nest during the day when the sand is not too hot, and closing the cages in the evenings so the night workers could collect hatchlings for weighing, measuring and biopsying. They would be released the following night- when they are most likely to escape the watchful eyes of predators.
The bulk of day work involved excavating nests that had hatched, or record unsuccessful nests where no eggs hatched.
This work was extremely labour-intensive. One person would locate, and dig an ever-collapsing area of sand that the night workers had marked out 2 months before, after observing the females lay and marking the location of her egg chamber. Digging had to be done gently enough to avoid harming any hatchlings that could be over 1m deep in the cool softer sand. Once, I had over half of my body length head down into a hole in the sand with the Mediterranean sun pounding on my back, I would carefully remove fragments and unhatched eggs and pass them up to my colleagues, along with any survivors that had struggled to get out, or stuck under plastic caught in the nest. Fragments and eggs would be ordered under a range of criteria, along with information about the nest that would be used for the numerous research projects taking place.
Working closely with fellow students, (mainly ecologists and zoologists) watching endangered animals from hatchlings to adulthood emerge, some for the first time, is something that many of us had spent our lives waiting to see. It gives you a special bond to the people you work with, to the country and to the beaches which I worked on every day for all but 1 day off I had in 6 weeks. The extremely hard work we did across the 3 bases in Northern Cyprus (one dealt with over 12,000 hatchlings this season!) is worth the lifelong friends, the experiences and the satisfaction you gain when you release a hatchling that you pulled from the plastics littered across the beaches. This was the experience of a lifetime, and I cannot wait to go back.

Mammalian biologist Dr Dawn Scott is urging people to feed dwindling numbers of hedgehogs during autumn to help them survive winter.
Dr Scott, Assistant Head our school of Pharmacy and Biomolecular Sciences, spoke out after media reports suggested people should refrain from feeding hedgehogs before hibernation.
She said: “I feed hedgehogs in the autumn to help them attain body weight before the winter and several animals may need this boost to obtain the body weight sufficient to survive hibernation.
“I would encourage feeding hedgehogs in the autumn and I would also encourage the establishment of wildlife-friendly gardens which promote natural food supplies for the hedgehogs.”
Dr Scott spoke on hedgehogs at last week’s British Science Festival (BSF). She said one media report, suggesting Dr Scott was asking people to should stop feeding hedgehogs during autumn, was misleading.
“I presented data on my findings on the impact of people feeding urban mammals including foxes, badgers and hedgehogs. I mentioned my concerns over the emerging impact of food supplied by householders on animal behaviour and stated more research was needed.
“The point of the BSF is to stimulate discussion and debate hence I raised the point of ‘do we actually know the impacts of people feeding wildlife and it might not always be beneficial’. As hedgehogs are in such decline we really do need to know the consequences of our actions in terms of long term affects and this urgently needs more research.
“I was concerned that hedgehogs were noted as active throughout December and January last year and that, although this is likely to be climate related, abundant food supply throughout winter in gardens could also be affecting hibernation timing.
“One of the ecological consequences of urban environments for animals is the potentially constant supply of food which could affect natural seasonal behaviour. Food reduction as well as temperature is a trigger for hibernating animals and so abundant food could potentially affect this trigger. Anthropogenic feeding and how it can disrupt hibernation patterns has been shown in some other species.
“I said I had no direct data on this, it was a point for discussion and raised as an area that needs to be researched in future. I linked this point with the emerging feeding habits of people towards other urban animals and said we need to look carefully at how, what and when we feed wildlife to maximise its benefit and reduce any potential detrimental effects.”
