Strength in numbers: monitoring of fungicide drug resistance with the help of 500 citizen scientists

In this post, Jennifer Shelton provides an insight into her PhD project which involves over 500 citizen scientists from across the world, in the hope of better understanding a species of fungus that is linked to disease.


It started by a poolside in Gran Canaria.

I was reading my book but thinking about the sticky films we use in the lab to cover plates of DNA that a former postdoc in my group had used to collect Penicillium spores for his study on the population genetics of ‘Alexander Fleming’s lucky fungus’. I’d already decided as part of my PhD to conduct a country-wide survey to determine background levels of Aspergillus fumigatus – a species of fungus – spores in the UK. I had put aside several weeks for driving around the country to collect air and soil samples, yet thoughts of a citizen science project kept buzzing. What if I asked individuals across the UK to collect samples of their local air on a single day, say summer solstice, and post them back to me?

Citizen science projects are increasing in popularity and rely on members of the public to voluntarily collect samples, process data or record observations as part of a research project. Some well-known examples include SETI@Home, which uses internet-connected computers to analyse telescope data in the search for extra-terrestrial life; Foldit, an online video game about protein folding and Swab & Send, a widespread swabbing exercise to identify novel antibiotics in the environment.

Tackling drug resistant infection through collaborative global action

Imperial’s Dr Esmita Charani and Dr Jamal Uddin, Child Health Research Foundation (CHRF), observing field work surveillance conducted by CHRF healthcare workers in Bangladesh as part of the demographic and disease surveillance initiatives aimed at reducing childhood morbidity and mortality.

Ahead of the recent G20 Summit in Buenos Aires, Professor Alison Holmes explained in an article for G20 Magazine why global collaboration is essential to minimising the impact of antimicrobial resistance (AMR) on healthcare.


The world faces the unprecedented challenge of drug resistant infection due to increasing AMR. Concerted global action is needed to address this pressing and alarming public health issue. Without a strong, unified response, the UN’s Sustainable Development Goals (SDGs) will not be met, and valuable progress will be lost.

The need for leadership

The continued inclusion of AMR in the G20 agenda, under the leadership of Argentina, is greatly welcomed. This year I was invited to speak in Buenos Aires on initiatives to optimise antibiotic use, at the International Congress on Infectious Diseases, co-hosted by the Infectious Diseases Society of Argentina. The ethos of shared learning and strong leadership was central in our discussions, and considered fundamental to effective action. (more…)

Noël hypothesis: my life as a medical statistician

This festive period Three Wise Women from the Faculty of Medicine will be giving us the gift of their wisdom.

Our final wise woman, director of the School of Public Health Professor Deborah Ashby, shares her joy of medical statistics, from working in neonatal research to taking on the Royal Statistical Society presidency. 


We Three Queens of Orient are…” came the dulcet sounds in the lead-up to Christmas. I looked up across the old Liverpool maternity ward, to see three colleagues singing and, channelling Morecambe and Wise, dancing towards me and my newborn daughter. The three women who had come to visit were all, like me, lecturers in medical statistics at the University of Liverpool, and that memory still brings a smile.

Although it was less glamorous than the alternatives, I’d chosen to give birth there, reasoning that if it went well, it didn’t matter where I was, but if not, I’d rather be somewhere with wide experience, actively engaged with and informed by research. In Liverpool, I had worked with the academic doctors from that maternity hospital, so knew I would get both. You might wonder why they had sought my advice, but research on babies involves analysing complex data on them, or designing studies to test competing treatments or strategies – all of which needs statistical skills along with clinical input.

Self-division: how I split my time between family life and cell cycles

This festive period Three Wise Women from the Faculty of Medicine will be giving us the gift of their wisdom.

Our second wise woman, research fellow Dr Alexis Barr, provides an insight into how she’s balancing family life with a research career.  


I never realised that when I started a family that other scientists would be so interested in my work/life balance. I am frequently asked how I manage a research career with bringing up two young children, aged two and four. Thankfully, it’s not as hard as you might think, but having a partner who shares the responsibility helps enormously.

I know why researchers are keen to talk about this as it seems to involve squaring a circle. Before I had children, I couldn’t easily conceive how working in a lab 8am – 7pm every day and often ‘popping in’ at weekends could work with caring for children. The problem is that it doesn’t, well at least not if you want to spend time with your children (which I do – not least because they’re hilarious). But it turns out that this isn’t a problem as there are other styles of working. Like most scientists I know, we love what we do so we’re quite motivated to find ways to make it work for us. (more…)

I can’t wait until I’m no longer waiting for the first Black scientist to win a Nobel Prize

The Wise Women

This festive period Three Wise Women from the Faculty of Medicine will be giving us the gift of their wisdom.

Our first wise woman, Dr Faith Uwadiae, highlighted success stories of Black scientists on her Twitter account every day throughout Black History Month 2018. In this post, she tells us what led to her taking action. 


The problem

I have been in the university academic system for almost a decade and in this time I have interacted with very few Black scientists. I have met a handful of Black PhD students and research assistants or technicians, one postdoctoral scientist, but sadly I’ve never been lectured by a Black scientist. When I attend scientific conferences or events I am frequently one of the few Black people in the room and often the only Black woman. In fact, Black professors are heavily underrepresented making up just 0.6% of UK professors, of which only 25 are Black female professors. Sadly, when people think about a scientist they don’t picture someone like me, i.e. Black, female and young, and instead default to the White, male and old archetype.

Scientists are much more diverse and I wanted to learn more about the stories of people like me. (more…)

World AIDS Day at 30: where are we in the fight against HIV/AIDS?

World AIDS Day 2018

Dr Kirk Taylor looks back at over 30 years of the HIV epidemic, from the advent of preventative therapy to the impact of HIV stigma that continues to plague forgotten populations.


Thirty years on from the first World AIDS Day we have seen enormous global progress towards ending the epidemic. The change that has happened within my lifetime is astonishing; HIV has gone from being a death sentence to a manageable condition with strategies to prevent transmission altogether. This World AIDS Day, I highlight the milestones achieved and where there is still work to do. (more…)

NHS England’s plans to cut prescribing for low-value items: well-intentioned but poorly implemented

Professor Azeem Majeed shares his take on the realities of NHS England’s proposed ‘do not prescribe list' for primary care.
Professor Azeem Majeed shares his take on the realities of NHS England’s proposed ‘do not prescribe’ list for primary care.


This week NHS England (the organisation responsible for managing the NHS in England) announced plans to curb the prescribing of ‘low-value’ items. This includes items such as silk garments, and bath and shower emollient for eczema and dermatitis. The plans follow on from earlier guidance issued by NHS England that aimed to limit the prescribing medications that are available over the counter, such as paracetamol and ibuprofen.

At a time when the NHS faces unprecedented workload and funding pressures, health professionals and the public all recognise the need to make the most efficient use of the resources available to the NHS; and prioritising key clinical areas such as cancer care. Prescribing costs in primary care, currently around £10bn annually, are a key component of the NHS budget in England. It is therefore entirely appropriate to look at this area to see where savings can be made without compromising patient care. (more…)

Back down to earth: From astrophysicist to desk-bound medical scientist

In this post, Dr Sujata Sridharan shares her career path, from graduating with an astrophysics degree to being a postdoc in brain imaging.


I’m not a scientist, not really. At least, that’s what I’ve heard countless times from my non-academic friends, and sometimes even colleagues. I’ve deduced that this belief dates back to my decision to take an MPhys in Physics with Astrophysics as my undergraduate degree.

Physics first

As a (comparatively) fresh-faced 18-year-old, I undertook my first degree at the University of Manchester, (somewhat naively) under the impression that astrophysics involved a lot of actual stargazing. My first year was a pleasant 60:40 split of lectures and laboratory-based work. Albeit the latter was rather generalised; at one point I remember making a hologram of a bronze Buddha statue for no apparent scientific reason. My main concern at that point was that I hadn’t yet bumped into Brian Cox, who had recently taken up teaching duties at the university in between – what we physicists considered – glamorous filming of the ‘Wonders of the Universe’ documentary series.

Building a heart, one cell at a time

Dr Michela Noseda took cardiac cells to the stage at her recent TEDx talk on how scientific approaches she uses can help us understand how to beat one of the biggest killers of our time – heart attacks.


Heart attack (myocardial infarction) remains the foremost killer worldwide. The prevalence remains high despite the fact that we have been reducing risk factors; stopping smoking, eating a healthy diet and exercising. In fact, the persistence of myocardial infarction as the most frequent cause of death is related to an ageing population and the move of people towards big cities. (more…)

Immune cell diet – a cure for asthma?

 

Gesa Albers was shortlisted for the MRC Max Perutz Science Writing Award 2018 for the following article on her PhD project studying how the metabolism of macrophages differs between asthmatic and non-asthmatic people.


You are on a holiday with a good friend walking along a path enjoying the stunning view and the beautiful scenery along the river. Suddenly, your friend starts coughing. He might have inhaled dust from the dry pathway. You stop to give him the water bottle from your backpack. The water does not help the coughing. He wheezes every time he breathes and you start panicking when you see that his face is getting paler and paler.

“I cannot breathe!” he says while wheezing.

You want to help him but you do not know what to do. What does he need? Do you have to call an ambulance? As the coughing and wheezing does not stop, you decide to call the ambulance. With shaking hands, you type in the number and call the paramedics. (more…)
