Science & Innovation

An Artificial Intelligence tool that could change the way we treat heart disease wowed the judges at this year’s Bright SCIdea competition. Now that the dust has settled, we asked Raphael Peralta, from the winning CardiaTec team, about winning the competition, the need for this technology, and tips for future participants. After winning this prestigious competition and coming away with the £5,000 first prize, the future is bright for co-founders Raphael Peralta, Thelma Zablocki and Namshik Han. So, how do they reflect on the story so far?

Bright SCIdea 2022 - Team CardiTec

Team CardiaTec (UK)

Tell us about CardiaTec
Cardiovascular disease is the world’s leading cause of death, and affects countless lives. Despite this, investment and innovation within the space has been severely stagnated, especially in comparison to fields such as oncology. The current treatment landscape remains unchanged, and treatments are most often prescribed in a standardised, one-size-fits-all approach. However, people are fundamentally different, and as shown by the Covid-19 pandemic, similar groups of people can experience a disease in a significantly different manner, and as such it is very important to understand biological processes at a patient level to produce effective therapeutic outcomes.

CardiaTec is leveraging artificial intelligence to structure and analyze large scale biological data that spans the full multiomic domain. This allows for a comprehensive understanding of disease pathophysiology to better develop novel and effective therapeutics for cardiovascular disease.

Casting your mind back to the moment you were announced the winner of Bright SCIdea 2020, what were your initial thoughts?
We thought we had a good opportunity to win it, but obviously when it was announced, it was a great feeling. Winning this competition is a further validation that what we are generating has real world value.

It was a great judging panel, with a breadth of experience across drug discovery and the pharmaceutical industry. We were up against immense global competition and the fact that we won shows that there’s a need for novel innovation in the cardiovascular space to ultimately drive the development of new therapeutics that are going to help change people's lives.

How did you think of the idea? Was there a ‘eureka’ moment?
The way the initial idea came about was through the identification that the cardiovascular space had a massive unmet need compared to other spaces such as oncology. I had worked with a cardiovascular company doing some consulting work and this is where it came to light.

In combination, multiomic techniques are becoming increasingly accessible in line with technological developments, which have made processes of next generation sequencing and proteomic profiling increasingly cheaper. These processes generate large amounts of data, which then lend themselves to applications of machine learning to derive biologically meaningful insights. These process, although becoming increasingly familiar in areas such as oncology, are highly underrepresented in cardiovascular disease, and thus there spans opportunity to develop completely unique and novel insights.

How does the technology work?
Here, CardiaTec uses data across genomics, epigenomics, transcriptomics, proteomics, and metabolomics, to generate novel biological insights with the help of AI and machine learning applications. Taking these many ‘omics’ into consideration is what defines a ‘multiomic’ approach. Biology is complex, and trends require full multiomic assessment to truly understand where dysregulation of specific processes is occurring, to then inform the best means of intervention.

CardiaTec is developing a platform, which with time will grow to become one of the most comprehensive foundations of cardiovascular disease biology. Results and outcomes are iteratively incorporated into the model, and new hypotheses are tried and tested across a range of pre-clinical settings. Collectively, CardiaTec aims to generate novel drug targets that can be used to help reduce the burden of disease in current and future patient population.

In the process of getting to the final, there were several opportunities to engage with entrepreneurs, investors, business leaders, and experts in intellectual property (IP). Can you share key takeaways from these sessions?
One of the most important things you can do is speak to people. Every business starts from an idea. As you start developing, you change and refine the business model. We take every chance to engage with people who have industry experience. It’s really important that we take the advice of these people on board; this is especially true in the field of biotechnology where you take risks across the technology side, the commercial side, and the biological side. It takes a lot of experience to mitigate those risks.

How difficult has it been taking that idea and turning it into a viable business proposition?
Thelma and I came out of the MPhil in Bioscience Enterprise at the University of Cambridge. It gave us this really strong foundation to start building. We also had the biological knowledge from our previous degrees. This framework, where we had key opinion leaders and great people in the field with whom we could bounce ideas off, was the first step. We saw that the idea was really positive and was received well by a lot of people. So, we thought: ‘we’re onto something’.

When building a biotech company, if you’re not passionate about it and don’t want to spend a lot of your time dedicated to the project, then it’s not going to take off. You need to be there to make changes, and really embrace and understand where you believe it’s going to go in line with the advice you've been given and the insights that you have generated.

We’re not only interested in understanding the intricate nature of biology. We’re also interested in how this has real life application in changing people’s lives. Every person we speak to has been affected in some way by cardiovascular disease.

I noticed that your presentation was really polished. Do you have any tips for people presenting in the final?
We’ve presented a lot of times so I think practice makes perfect. With a presentation, you need to be able to tell a story. It’s all about the storyline and building that image. You have to take care and be diligent in the process. Take time to make sure everything is structured correctly and that the story flows. Don’t be afraid to present to a lot of people who will give you advice. Take the time to make the amendments and run it through again and again, and see what the response is. So, take your time on the presentation to get your story across.

You were both very calm when the judges’ questions came. How did you prepare for these questions?
Out of this Cambridge network, the people we spoke to all asked the right questions. You see the pattern of these questions. They all want to know similar things. So, once we identified that pattern, we wrote down the questions that were important from our conversations and we practiced responses to these questions, which were by this point, fully embedded into the company’s business model; which then lends itself to an insightful, actionable response.

How are you going to use the £5,000 prize money and what’s next?
We’ll put the prize money towards refining of some of our technology. In terms of what’s next, Thelma (Zablocki), Namshik (Han), and I are dedicated to this company. We want to see it through and eventually make a drug that ends up reaching patients. This will take a long time.

To see that in the real world, where someone’s getting prescribed a drug that you discovered would be incredible.

Careers

Life is busy for Rhys Archer. Outside of her work as EPSRC Doctoral Prize Fellow in Biomedical Materials at the University of Manchester, she founded Women of Science to share stories about real women working in science. She has championed STEM in schools in her spare time and received the Robert Perrin Medal from the Institute of Materials, Minerals, and Mining – all before her 30th birthday.

Rhys is also refreshingly forthright in her views. She took the time to speak to us about everything from attitudes towards disability in academia, the problem with STEM statistics, and finding that sense of belonging in science.

Would you mind telling me about your work at the University of Manchester and the research areas that interest you most?
My research interests have always been interdisciplinary – I am a bit of a magpie when it comes to research and I get excited by projects in different areas. Luckily, being a researcher in materials science means that I can apply my knowledge and skills in a wide array of areas and industries. I have recently finished my doctoral studies looking at how carbon fibre composites are damaged during impacts, and how to toughen them while keeping composites light weight, which is particularly useful in the aerospace industry. However, I have since moved over to research in biomedical materials, specifically within tissue engineering, where I am researching biocompatible composite scaffolds for tissue regeneration.

You set up Women of Science in 2016 to share stories about real people in science. How has this been?
When I set up Women of Science, I first looked at it as a personal project that could be of use in schools to young people. However, it became apparent fairly quickly that access to relatable role-models in STEM was needed, not just in schools but also for women across the STEM industry.

Since then, we have been fortunate to be awarded funding to grow the work we do and expand our audiences. One of the most important actions I have taken with Women of Science is to set up an advisory board (which includes a diverse range of women) to share ideas and to influence the direction and activities of Women of Science.

As well as the impact on others, Women of Science has had a huge impact on me personally. When I set up Women of Science I was going through a difficult period of feeling isolated, and found it difficult to feel a sense of belonging in science and in research. By reaching out and hearing other women’s stories – not just their achievements, but also their doubts, worries, and difficulties – I found that I did belong in STEM. I just had to search for it.

Would you mind sharing some of the successes and challenges you’ve experienced in your own career?
At 29, towards the end of my PhD, I was diagnosed as autistic. Looking back, I can see that the challenges I faced, particularly because of depression, anxiety, and isolation, were due to my needs not being considered or met. Being disabled in academia is an ongoing challenge. It is still a fight to gain equitable working arrangements, opportunities, and acceptance.

However, I can also see how the successes I have had, such as setting up Women of Science, and being a part of other projects are a result of ‘being different’. My strongest quality is a diversity of perspective and experience and an eagerness to be a part of a range of different projects.

You have championed inclusivity in STEM. Do you think academic institutions and other workplaces could be more inclusive?
Yes. I think there is a huge amount of awareness and conversation about inclusivity in academia and industry, but not nearly as much action and intervention. Often I see workplaces with inclusive policies, but with little consideration of monitoring, evaluating, or reconsidering those policies. We must move past equity, diversity, and inclusivity being a checkbox exercise. The issues faced by women in the workplace are intersectional and complex, and so require well considered, complex solutions.

According to WISE, women now make up 24% of the STEM workforce in the UK. It estimates that this number could rise to 29% by 2030. What do you think about these figures?
While the number of women in STEM is a common metric when considering equality, this does not accurately portray issues surrounding inclusion and belonging. How are women treated? Do they have the opportunity to advance? Are there equitable policies and measures in place? This is particularly true of women in STEM who identify with other protected characteristics around race, disability, sexual orientation, and class. Once you dig into the statistics (where available) further, it is clear that the numbers given are not sufficient to describe the current situation for all women in STEM.

Also, the ‘leaky pipeline’ model is often considered, that is, that the number of women in STEM fall as we follow the statistics from school, to university, and onto the workplace. However, what is not always considered is that, as with a leaky pipeline, when more women are added, rather than ‘fixing’ the pipeline, the cracks become more obvious. Eventually, we reach a point when the pipeline is fractured. We must focus on repairing these cracks, not just increasing a numerical metric.

Additionally, in this current climate, it is incredibly difficult to make predictions as to what the future holds for the number of women in the STEM workforce. A couple of years ago, we could not foresee the impact that a global pandemic would have on women. When we consider the possible effects of climate change over the next decade, can we predict the burden that will be placed on women, or how this will affect women’s choices?

What’s next for you? Are you involved in any exciting projects?
With Women of Science, we have three projects that will be launched towards the end of the year, including a new website, flashcard activities for young people, and a report on the impact of the pandemic on women in STEM. Further ahead, I would love to expand the reach of Women of Science further, working with podcasting and film, as well as reaching out to policy makers. Personally, I am excited to get my teeth stuck into a new research project and see where that leads, as well as doing more teaching, consulting, and any other opportunities that come my way!

Energy

We are increasingly conscious of the need to recycle waste products, but it is never quite so easy as rinsing and sorting your waste into the appropriate bins, especially when it comes to plastic.

Despite our best intentions, only around 16% of plastic is recycled into new products — and, worse, plastics tend to be recycled into low quality materials because transformation into high-value chemicals requires substantial amounts of energy, meaning the choices are either downcycling or prohibitively difficult. The majority of single-use plastics end up in landfills or abandoned in the environment.

This is a particular problem when it comes to polyolefins such as polyethylene (PE) and polypropylene (PP), which use cheap and readily available raw materials. Approximately 380 million tonnes of plastics are generated annually around the world and it is estimated that, by 2050, that figure will be 1.1 billion tonnes. Currently, 57% of this total are polyolefins.

Why are polyolefins an issue? The strong sp3 carbon–carbon bonds (essentially long, straight chains of carbon and hydrogen atoms) that make them useful as a material also make them particularly difficult to degrade and reuse without intensive, high energy procedures or strong chemicals. More than most plastics, downcycling or landfill disposal tend to be the main end-of-life options for polyolefins.

Polyethylene is used to make plastic bags and packaging.

Now, however, a team of scientists from MIT, led by Yuriy Román-Leshkov, believe they may have made a significant step towards solving this problem.

Previous research has demonstrated that noble metals, such as zirconium, platinum, and ruthenium can help split apart short, simple hydrocarbon chains as well as more complicated, but plant-based lignin molecules, in processes with much lower temperatures and energy.

So the team looked at using the same approach for the long hydrocarbon chains in polyolefins, aiming to disintegrate the plastics into usable chemicals and natural gas. It worked.

First, they used ruthenium-carbon nanoparticles to convert more than 90% of the hydrocarbons into shorter compounds at 200 Celsius (previously, temperatures of 430–760 Celsius were required).

Next, they tested their new method on commercially available, more complex polyolefins without pre-treatment (an energy intensive requirement). Not only were the samples completely broken down into gaseous and liquid products, the end product could be selected by tuning the reaction, yielding either natural gas or a combination of natural gas and liquid alkanes (both highly desirable) as preferred.

Polypropylene is used in bottle caps, houseware, and other packaging and consumer products.

The researchers believe that an industrial scale use of their method could eventually help reduce the volume of post-consumer waste in landfills by recycling plastics to desirable, highly valuable alkanes — but, of course, it's not that simple. The team says that more research into the effects of moisture and contaminants in the process is required, as well as product removal strategies to decrease the formation of light alkanes which will be critical for the industrialisation of this reaction.

However, they believe the path they're on could lead to affordable upcycling technology that would better integrate polyolefins into the global economy and incentivise the removal of waste plastics from landfill and the environment.

Science & Innovation

The Organisation for Economic Cooperation and Development (OECD) has published its Science Technology and Innovation Outlook 2021: Time of Crises and Opportunity report.

Published at the beginning of 2021, the report focuses on the ‘unparalleled mobilisation of the scientific and innovation community’ in response to the covid-19 pandemic. The report indicates that newly funded research initiatives have been established by public research agencies and organisations, private foundations and charities, while the health sector has similarly invested in an array of research programmes worth billions of dollars in record time.

The pandemic has led an unprecedented mobilisation of the scientific and innovation community

However, the report also exposes gaps in overall system resilience to future crises. ‘It’s a wake-up call that highlights the need to recalibrate science, technology and innovation (STI) policies, so that they better orient research and innovation efforts towards sustainability, inclusivity and resiliency goals,’ the report asserts.

Highlighting the rapid response by governments around the world, the report indicates that in the first few months of the pandemic, national research funding bodies spent around $5 billion on emergency financial support. This includes $300 million in Asia-Pacific, excluding China, over $850 million in Europe and more than $3.5 billion in North America. At the same time, research efforts led to around 75,000 scientific publications on covid-19 being released between January and November 2020, the report says. The largest share came from the US, followed by China and the UK. Research databases and scientific publishers removed paywalls so that covid-19 related information could be quickly shared.

‘These developments mark important changes that could accelerate the transition to a more open science in the longer run,’ the report says. It is also noted that not only have researchers continued their work with more than three quarters of scientists indicating that they had shifted to working from home at some point in 2020, but almost two thirds experienced, or expected to see, an increase in the use of digital tools for research as a consequence of the crisis. The report also mentions the contribution of the general public, with so called ‘frugal innovations’ in response to shortages of medical equipment and emergency supplies.

Looking to the future of the research community, the report says that postgraduate training regimes require reform to support a diversity of career paths. ‘The crisis has shown that the need for STI expertise is not limited to the public laboratory; it is also important for business, government and NGOs […] Reforming PhD and post-doctoral training to support a diversity of career paths is essential for improving societies’ ability to react to crises like covid-19 and to deal with long-term challenges like climate change that demand science-based responses […] There has been a 25% increase in the number of people with PhDs in OECD countries over the past decade with no corresponding increase in academic posts. The pandemic is expected to make matters worse, more than half of the scientists participating in the OECD Science Flash Survey expect the crisis to negatively affect their job security and career opportunities,’ the report says.

Post-graduate training regimes require reform to support a diversity of career paths

While still in the midst of the pandemic, the report stresses that STI policies now need to be reoriented to tackle the challenges of sustainability, inclusivity and resiliency. ‘In the short-term governments should continue their support for science and innovation activities that aim to develop solutions to the pandemic and mitigate its negative impacts, while paying attention to its uneven distributional effects. Science for policy will remain in the spotlight as governments seek to strike the right balance in their response to covid-19. This will effect public perceptions of science that could have long term implications for science-society relations.’

The report concludes that governments now have the task of developing public sector capabilities to deliver more ambitious STI policy. This will require engagement from stakeholders and citizens in order to capture a diversity of knowledge and values.
