York University Postdoctoral Fellow awarded the Polanyi Prize in chemistry

Ramón Alain Miranda Quintana, a postdoc and York Science Fellow at York University’s Faculty of Science, is the John Charles Polanyi Prize winner in chemistry, Ontario’s Ministry of Colleges and Universities announced Tuesday.

He is one of five university researchers in Ontario who have been recognized with a 2019 Polanyi Prize in the fields of chemistry, literature, physics, economic science and physiology/medicine.

“Their work helps advance Ontario’s innovation economy, strengthening our province’s reputation in research, while changing the way we approach and understand issues that directly impact Ontarians,” said Ross Romano, minister of colleges and universities.

The prizes are awarded in honour of Ontario’s Nobel Prize winner John C. Polanyi, who won the 1986 Nobel Prize in Chemistry for his research in chemical kinetics.

“Receiving a John Charles Polanyi Prize is a prestigious honour for early-career scientists. York University is proud to see one of our own researchers receive this recognition,” said Rui Wang, dean of science and interim vice-president research and innovation at York University. “Dr. Miranda Quintana came to York University as a York Science Fellow and his work will potentially lead to game-changing advances in areas such as electricity transmission and managing nuclear waste. York University continues to cultivate and support brilliant young researchers like Dr. Miranda Quintana.”

Miranda Quintana is researching new ways to understand the behaviour of complex chemical compounds using computational algorithms, which could lead to new innovations in industry and health. Current tools for theoretical chemistry can explain only about 90 per cent of chemical molecules.

“For the remaining 10 per cent, the existing methods of testing these compounds computationally are so inefficient it could take years to arrive at even the simplest calculation and, in some cases, billions of years,” says Miranda Quintana, who came to York from Cuba in 2018. “That 10 per cent contains molecules that are really important with potentially huge applications.”

These include molecules with rare metal centres that are found in nuclear fuels, nuclear waste and even some enzymes in the human body. Understanding these enzymes better, could lead to medical breakthroughs in treatments.

The goal is to create highly efficient and accurate computational tools that are also safer than traditional chemical lab experiments. “Once we are able to do that, we can apply these new tools to these compounds to understand how they behave, how their function changes when their structure is modified, and how to make them more efficient,” says Miranda Quintana, whose supervisor at York University is the Chemistry Department Chair René Fournier.

Already, Miranda Quintana and a team of colleagues have developed a general and convenient framework called FANCI (Flexible Ansatz for N-body Configuration Interaction) to test various theories about how these complex compounds behave and function using simple calculations, a combination of math and coding.

New tools such as FANCI would potentially allow researchers to understand how to modify these compounds so they convert energy more efficiently at regular temperatures, rather than needing to be cooled to close to minus 273.15 degrees Celsius, as is the case now. This could make the creation of superconductive materials possible and hold the key to revolutionizing the power industry, creating microscopic data storage devices, and better quantum computers. It could also lead to the creation of new nuclear fuels and a simpler way to dispose of nuclear waste.

The idea is to make FANCI software available on open source so researchers can study processes, such as magnetism, superconductivity and thermodynamics, and have a reliable answer much more efficiently than with currents methods. It would speed up the testing of ideas and lead to faster innovations.

The 2018 Polanyi Prize winner for chemistry was also from York University, Assistant Professor Christopher Caputo, whose research explores ways to remove precious metals from the manufacturing process for plastics, pharmaceuticals and other industrial products. His goal is to make production less expensive and more sustainable.

The Polanyi Prizes are awarded each year to innovative researchers in Ontario who are either continuing postdoctoral work or have recently gained a faculty appointment. Each of this year’s winners will receive $20,000 in recognition of their exceptional research in the fields of chemistry, physics, economic science and physiology/medicine.

Two new Organized Research Units in the process of being chartered

York University’s Scott Library hosted an Organized Research Unit (ORU) open house on Jan. 29, fittingly presented in the library’s Learning Commons Collaboratory. The event provided students, faculty, community members and researchers from the ORUs an opportunity to learn about the range of work being done at the University’s 25 ORUs.

“What’s unique about York?” asked Interim Vice-President Research & Innovation Rui Wang, who moderated the event’s formal program. “Just look at our ORU’s.”

Celia Haig-Brown
Celia Haig-Brown

Celia Haig-Brown, associate vice-president research, who also provided remarks at the open house, similarly praised York’s ORUs. “This is what universities are about,” Haig-Brown explained. “When there is a group of committed and excited researchers who want to come together with some common sense of identity and yet some very different ways of thinking about things, the research units are a wonderful place to be.”

In this light, Haig-Brown was excited to announce to attendees that York is in the process of chartering two new ORUs: the Bee Centre, and the Centre for Indigenous Knowledges and Languages.

The announcement sparked intrigue and excitement at the already engaging and interactive event. “It was such a pleasure to host the event in the Libraries for the Vice-President Research and Innovation where our community could easily meet and hear about the ORUs and the wealth of research they generate. The event was really successful in giving visibility to the ORU’s. I, myself, was really inspired by the cross section of interdisciplinary research I was seeing.” said Joy Kirchner, dean of libraries. “The ORU model has been tremendously successful in generating the kind of innovation and interdisciplinarity that is really a highlight at York.”

Faculty and researchers involved in developing the new ORUs were on hand with tables and exhibits at the open house, and they were eager to talk about the exciting developments.

Bees from York University's Collection

Folks swarmed to the Bee Centre’s table where Liam Graham, collections manager at York University’s Packer Lab for bees, spoke about the importance of deepening our understanding of bee populations through interdisciplinary research. “In our collection we have historical data and records of bees for 60 years,” Graham said. “You can keep track of populations and how they change over time. It’s important to know how many species we have and learn the plants they use.” York’s bee researchers hope to focus on preserving biodiversity, according to biologist Clement Kent. “If we don’t have many different species for the plants that rely on pollination for their genetic boosting, they start declining, and that’s happening in a few places.”

Haig-Brown, who highlighted the increasing public understanding of the critical roles that bees play in pollination, was enthusiastic about the different disciplines involved in bee research at York, ranging from biologists to social scientists and even including a mathematician. “Looking at the possibilities of the centre, they bring incredible strength to research at York, drawing on so many disciplines,” she stated.

Many students and faculty were eager to talk to the team at the Centre for Indigenous Knowledges and Languages table, where Assistant Professor Ruth Koleszar-Green, co-chair of York’s Indigenous Council and special advisor to the President on Indigenous Initiatives, was equally eager to discuss the importance of creating a space for Indigenous academics to come together. “There are now 20 Indigenous faculty members, and in our research, we need some specific supports, ” explained Koleszar-Green. She emphasized the diversity of Indigenous research happening at York, ranging from art and pedagogy to the studies of labour and infectious diseases. “We aren’t just looking at historical space. A lot of us have been doing research that brings people into spaces.”

Haig-Brown echoed the enthusiasm for bringing often-isolated Indigenous faculty together. “I think this is going to put York on the map in terms of commitment to Indigenous faculty, researcher and students,” she said, noting that it has been one of her goals to continually contribute to creating space for Indigenous faculty and researchers to shape what goes on at York. “The focus on language is particularly important,” Haig-Brown continued. “The restoration of languages which residential schools attempted to destroy is integral to bringing Indigenous knowledges into contact with university knowledges.”

Both new ORUs are awaiting Senate approval, and the community can expect more information in the coming weeks and months.

Two $900K grants will allow physicists to test for electron electric dipole moment

Eric Hessels
Eric Hessels

The reason why there is a lot of matter in the Universe, such as electrons and protons, but no anti-matter (anti-electrons and antiprotons) is a riddle many scientists worldwide are still trying to solve. York University Distinguished Research Professor Eric Hessels of the Faculty of Science recently received two grants of $900,000 each over three years from the Alfred P. Sloan Foundation and the Gordon and Betty Moore Foundation to begin a program that he hopes will help bring clarity.

Eric Hessels

He will work with the EDM3 (pronounced EDM cubed) collaboration at York on the project, titled “EDMcubed: an electron Electric Dipole Measurement using Molecules in a Matrix,” to measure the electric dipole moment of the electron.

“This is one of the great unsolved mysteries of physics, since the laws of physics, as we understand them today, would not allow for any significant imbalance between matter and antimatter,” said Hessels. “As a result, the laws of physics need to be modified. Modifications that solve the matter-antimatter mystery also predict that the electron will have an electric dipole moment.”

The electron is expected to have a non-zero electric dipole moment – a very slight a non-spherical charge distribution. However, the mechanism that causes this dipole is unknown.

“The EDM3 collaboration has devised a clever way to measure the electron electric dipole moment that involves embedding a large number of polar molecules into solid cryogenic argon,” says Hessels, who also received about $800,000 total from the Natural Sciences and Engineering Research Council of Canada and the Templeton Foundation last year.

Precise electron electric dipole moment measurements will guide extensions to the Standard Model, while the EDM3 method has the potential to reduce the electron electric dipole moment uncertainty by up to five orders of magnitude.

The EDM3 method uses a large sample of polar molecules embedded within a rare-gas matrix. As the molecules are stationary in the matrix, it allows for long measurement times. This could allow the researchers to reach statistical sensitivities that are many orders of magnitude beyond the current electron electric dipole moment limit.

It could also help answer the question – what happened to all the anti-matter after the Universe was formed.

A prescription for change? International research collaboration to explore social innovation in pharmaceuticals

Pharmaceutical Industry
Pharmaceutical Industry

Conor Douglas, an assistant professor of Science and Technology Studies at York University, believes there are plenty of inequalities in the ways we produce and access pharmaceuticals. From his PhD research on patient participation in medical research to his post-doctoral studies on expensive drugs and coverage decision making for rare diseases, Douglas has devoted much of his career to interrogating the significant established power interests and issues of access and inequality at play in one of the major tools through which Western medicine is practiced.

Today, his research is focused on change. “In an industry this size, with a shifting landscape like this, there’s room for other ways of doing things,” explains Douglas. Joined by an international team of researches and supported by new funding from The Trans-Atlantic Platform for the Social Sciences and Humanities (T-AP), Douglas is looking for examples of how social innovation models that challenge existing modes of for-profit research and development can inform changes in the pharmaceutical industry.

Conor Douglas
Conor Douglas

According to Douglas, the shifting landscape in the pharmaceutical industry, driven by increased costs, the rise of genetic testing and personalized medicine, and challenges gathering traditional evidence for regulators, are creating challenges for public health care systems here in Canada and around the world.

“New drugs aren’t picked off trees,” says Douglas, “and they don’t fall out of the sky. Which ones succeed and which fail is a complicated dance between regulators, innovators, a pharmaceutical industry looking for profit, markets, patients, and social desirability.”

The pharmaceutical industry’s familiar refrain is one of an “innovation crisis” driven by the high costs of bringing drugs to market. Historically, as drug developers sought to re-coup the costs not only for their successful products but also for those that failed in research and development, smaller vulnerable populations such as rare disease patients were given a bitter pill to swallow. Seen as an unattractive market for the industry, many rare disease patients went for a long time without treatment, and when policy incentives were employed to encourage development of more niche drugs, these patients saw huge price tags. Compounding this issue for patients, industry and policy makers, the nature of drugs for rare diseases meant a smaller sample size for trials, leading to less evidence for research and development, as well as for drug regulators.

Today’s pharmaceutical industry, increasingly influenced by new understandings of genetics and a shift toward behavioural treatments, is challenging patients in a new way, as common conditions are being subdivided into smaller and smaller subsets based on genetic makeup. “The nature of pharmaceutical research and development is shifting – now,” explains Douglas. “The era of blockbuster drugs is over.” As old products coming off patents and traditional revenues drying up, companies are moving toward a niche development model. With more specialized products coming to market, the industry is viewing rare diseases as a business opportunity.

Pharmaceutical Products

“This is a good outcome,” says Douglas. “We are increasing our understanding of rare diseases. We want more treatments, more options.” According to Douglas, however, more progress is still needed. That’s where social innovation comes in.

Social innovation, which typically refers to non-market forms of innovation that address vulnerabilities rather than profit motives and usually involve users in the innovation process, is the basis of Douglas’ current project.

T-AP recently announced that Douglas and a team of researchers including Larry Lynd from British Columbia, Fernando Aith from Brazil,  Vololona Rabeharisoa from France and Ellen Moors from the Netherlands are awardees of their social innovation call for their project, Social Pharmaceutical Innovation (For Unmet Medical Needs), or “SPIN.”

The SPIN researchers will be digging into the social, political, legal, regulatory, financial and biological factors influencing the pharmaceutical landscape in their partner countries, as well as variations between the countries, hoping to identify examples of social innovation and understand the barriers to their success as well as how to support them with policy interventions.

Douglas also hopes the project will lead to “a cross-fertilization of ideas between the countries,” he explains. “Bringing the actors together, the people who are actually doing it.” Beyond producing a white paper summarizing their findings, Douglas intends to bring together patients, practitioners, regulators and other actors in the pharmaceutical landscape for practical workshops where they can react to the research, give input and hopefully co-produce some of the findings themselves.

Science students interested in gaining hands-on, paid research experience during summer 2020 are invited to apply the Faculty of Science Dean’s Undergraduate Research Awards (DURA) program and the NSERC Undergraduate Student Research Award (USRA) program.

Ellahe Fatehi recipient of 2019 DURA award

The Faculty of Science will be offering 12 DURAs, which are complementary and run parallel to the NSERC USRA program.

“By continuing the DURA program, we are making it possible for more of our top undergraduate students, including international students, to contribute to research in the Faculty of Science and to learn more about what frontline research really involves,” said Jennifer Steeves, associate dean of research and graduate education in the Faculty of Science.

The value, structure and eligibility requirements of the DURAs are similar to those of the NSERC USRA program; however, only undergraduates in York’s Faculty of Science are eligible for the DURAs, and international undergraduates are also eligible to apply to the DURA program.

DURAs and USRAs are held over 16 consecutive weeks through the summer, and all award recipients in the Faculty of Science will have an opportunity to participate in the 2020 Summer Undergraduate Research Conference hosted by the Faculty at the end of the summer. See highlights from last year’s conference.

“The conference is an amazing opportunity for students to present their summer research projects, practice science communications, and meet and learn from other students,” said Steeves.

Applications are due Friday, Feb. 21. Application instructions can be viewed here.

Calling all researchers: York’s Research Commons is offering two new workshops

research graphic

The new Research Commons at York University, which was created in 2019 by the Vice-President Research & Innovation, is comprised of a group of seasoned researchers and sector-leading research staff members. The group supports research intensity across the University.

The major emphases during its first year will be to increase tri-council grant applications and success through a supportive skills and mentoring program for new faculty members at York University. In keeping with that goal, the Research Commons has organized two workshops for January:

Concur Workshop
Jan. 21
, from 10 a.m. to 12 p.m. in Room 519 Kaneff Tower, Keele Campus
The Concur workshop will teach participants about how to manage administrative tasks in Concur. This two-hour workshop will offer insight on the ins and outs of the Concur expense system. Participants will have an opportunity to work directly with staff from General Accounting and Research Accounting. Skills taught include accessing Concur, creating and submitting expense reports and the top reasons why reports are returned. There will also be information about the new tri-council guidelines and how these guidelines can impact research expenses.

The World According to CIHR Workshop
Jan. 29, from 10 a.m. to 12 p.m. in Room 626, Kaneff Tower, Keele Campus
The workshop offers tips and insights associated with being a continuously funded Canadian Institutes for Health Research (CIHR) researcher. Participants will hear from a panel of highly successful researchers receiving CIHR funding. There will be opportunities to ask questions and have open discussions with the panel participants.

Both workshops are free and open to early, mid-level and senior researchers at York University. To learn more, visit the Research Commons website.

Two York University professors receive large NSERC grants for research and development

research graphic

Two York University professors have received Natural Sciences & Engineering Research Council of Canada (NSERC) Collaborative Research and Development (CRD) Grants. The grants were awarded to Professors Gunho Sohn of the Lassonde School of Engineering and Faculty of Science Professor Derek Wilson, York Research Chair in Molecular Mechanisms of Disease and director of the Centre for Research in Mass Spectrometry. These large grants support well-defined projects undertaken by university researchers and their partners.

“York is delighted to see Lassonde Professor Gunho Sohn and Science Professor Derek Wilson awarded NSERC CRD Grants,” said Rui Wang, interim vice-president research & innovation. “These grants will expand the scope of research undertaken at York, foster dynamic interaction between discovery-based and innovative research, and allow the research results to be translated into new knowledge, products or processes.”

Sohn’s project uses artificial intelligence to update Canada’s infrastructure

Gunho Sohn

Sohn was awarded a grant worth $1,024,000, from NSERC, for his project. Additional cash and in-kind contributions made from industrial partners were also significant: the total cash contribution is approximately about $1.5 million ($1,536,000 total; $512,000 from Teledyne Optech) and $1 million in-kind contribution ($1,048,146). Total funding is $2.5 million over four years.

This project seeks to update Canada’s critical infrastructure – the independent network of utilities, transportation and facilities. Although Canada is the second-largest country in the world (in terms of area), with the world’s 10th largest economy, one-third of its infrastructure is in need of a significant update. In collaboration with Teledyne Optech, Sohn’s project will develop an advanced data processing system using a specific type of artificial intelligence (AI), called deep neural network, which has recently achieved remarkable success in computer and robotic vision and machine learning.

“This work will allow for the autonomous recognition of infrastructure assets using high-quality 3D models of critical networks, thus contributing to the field of infrastructure management and improving urban sustainability as a whole,” Sohn explains.

Importantly, this project will also train highly qualified personnel and, in this way, will contribute to Canadian industries and the fields of AI technologies, infrastructure management, urban planning, and 3D mobile mapping systems.

Wilson’s project will accelerate the development of new therapeutics

Derek Wilson
Derek Wilson

Wilson was awarded a grant worth $1,040,000 from NSERC, for his project: The Technology-Enhanced Biopharmaceuticals Development and Manufacturing (TEnBioDev) initiative. With additional cash and  in-kind contributions from industry, the total funding comes to $2.2 million over four years.

This project is aimed at the implementation of new Canadian bioanalytical technologies to accelerate pre-clinical development and enable precision manufacturing of protein therapeutics. The initiative links platforms developed by Canadian instrument manufacturer SCIEX, through unique technologies, methods and expertise held primarily at York University to the drug development pipelines of Canada’s research-active biopharmaceuticals companies Sanofi Pasteur, Treventis and Immunobiochem.

“Protein therapeutics have numerous advantages over conventional drugs, most stemming from the fact that they can be precisely directed at their intended molecular targets, even in the exceedingly complex environment of the cell. This makes protein therapeutics both highly potent and generally less prone to side-effects,” Wilson explains.

This work has huge implications for vaccines – the majority of which are protein therapeutics. The total market for protein therapeutics extends well into the hundreds of billions annually, says Wilson.

“Being home to a number of international leaders in protein therapeutics development and innovative biotech startups, Canada is well positioned to achieve and maintain a global leadership position in this industry,” he says.

CRD Grants are intended to:

  • Create collaborations among Canadian universities and private and/or public sector partners that lead to advancements that, in turn, result in economic, social or environmental benefits for Canada;
  • Provide an enhanced experiential learning environment for graduate students and postdoc fellows; and
  • Allow partners to access the unique knowledge, expertise, infrastructure and potential highly educated and skilled future employees graduating from Canadian universities.

Both grants were announced in October 2019. To learn more about Wilson, visit the Wilson Lab website, or his Faculty profile page. To learn more about Sohn, visit his Lab’s website or his Faculty profile page.

Research on responsive robots, programmed to help humans in some way and facilitate fast and effective human-robot interaction, is usually set on land. Robots that function underwater is another whole matter. This is the novel frontier of York University’s Department of Electrical Engineering & Computer Science in the Lassonde School of Engineering – a recognized leader in robotics.

In a paper that appeared at the 14th annual ACM/IEEE International Conference on Robot-Human Interaction (2019) in Korea, graduate student Robert Codd-Downey and Professor Michael Jenkin describe a new method for underwater human-robot interaction, which they created.

This image illustrates the diver’s body parts that the robot is able to recognize

“This research borrows from the long-standing history of diver communication using hand signals. It presents an exciting opportunity to develop a marketable product that assists robot-diver interactions underwater,” Codd-Downey explains.

The work was funded by the Natural Sciences and Engineering Research Council of Canada’s Canadian Robotics Network and Vision: Science to Applications (VISTA). Codd-Downey received a VISTA doctoral scholarship to undertake the work in 2017. Jenkin, a member of both VISTA and the Centre for Vision Research at York, supervised the work. He is an international expert in mobile, visually guided autonomous robotics; computer vision; and virtual reality.

VISTA advances visual science through research

This is an excellent example of the groundbreaking research that VISTA supports. VISTA is a collaborative program funded by the Canada First Research Excellence Fund that builds on York’s world-leading interdisciplinary expertise in biological and computer vision.

VISTA essentially asks: “How can machine systems provide adaptive visual behavior in real-world conditions?” Answering this question will provide advances to vision science and exciting, widespread applications for visual health and technologies.

“Our overarching aim is to advance visual science through research that spans computational and biological perspectives and results in real-world applications,” says VISTA’s Scientific Director, Professor Doug Crawford.

Underwater represents certain challenges for robots

Through this new work, Codd-Downey and Jenkin were searching for a better way for human-robot interaction to take place underwater. “Current methods for human-robot interaction underwater seem antiquated in comparison to their terrestrial counterparts,” Codd-Downey explains. “And humans can’t operate their vocal cords underwater, which prevents voice communication,” he adds.

Other complications include the fact that acoustic modems are bulky and power intensive; and mechanical interaction devices, such as keyboards, joysticks and touchscreens, don’t function properly underwater without significant protection from the elements which makes them difficult to operate.

So, the researchers turned to tried-and-true diver communication hand signals. The Professional Association of Diving Instructors (PADI) defines a number of common hand signals. The gesture language combines hand configuration with arm trajectories to encode messages. Commercial divers and technical diving groups have defined additional signals useful for specific tasks.

Common PADI hand signals. The hand signal illustrations are provided by PADI and are used with PADI’s permission.

How does the robot recognize the hand gestures?

To facilitate and ensure that the robot recognizes the gestures, Codd-Downey and Jenkin broke down the process into four steps, detailed below.

Step 1: Object recognition: The first step involves ensuring the robot recognizes the body parts of the diver with whom it will be communicating – specifically the person’s head and hands. Here, the researchers were able to program the robot to a high degree of accuracy.

Step 2: Hand and head tracking: In this step, the researchers programmed the robot to ensure that it is able to track the hands and head of the diver.

Step 3: Hand pose classification: Again, the researchers ensured that the robot could identify the number of fingers and the direction of each palm of the diver. Interestingly, the combination of these two parameters (fingers, direction) define 25 different classes. [Classes refer to number of different hand poses used in PADI gestures.]

Step 4: Translation: The previous three steps generate data that is interpreted or translated to the robot.

Codd-Downey elaborates on Step 4: “The OK gesture, for example, can be interpreted as IDLE-OKIDLE. Where IDLE represents a return to none gesturing posture/action. A more complicated sequence of gestures can be interpreted as IDLE-YOU-STALL-FOLLOW-ME-IDLE. Where STALL represents a pause or break in the gesture sequence without returning to an IDLE state.”

In addition to hand signals, the researchers also used light-based communication methods to control the underwater robot either remotely or by a nearby diver.

Codd-Downey’s work in underwater human-robot communication has not gone unnoticed. He received an award for the best demonstration at the June 2018 Space Vision and Advanced Robotics Workshop for related work on light-based communication between two robots.

This cutting-edge work continues. “Work on hand gesture recognition is an ongoing part of my thesis,” Codd-Downey explains. He adds that he is currently collecting additional annotations to train the hand pose classifier and identifying common phrases that divers use to communicate to train the models for in-water testing.

Just who are the winners and losers when biomedical advances eliminate death?

Professor Regina Rini, Canada Research Chair in Philosophy of Moral and Social Cognition and core member of Vision: Science to Applications (VISTA), has a way of raising previously unimaginable moral questions that cut to the heart of things. She has done it again, this time in the esteemed Times Literary Supplement. Her article, “The Last Mortals,” was released to a global audience in May 2019.

Rini starts with the supposition that biomedical advances could mean eternal life in 100 years’ time. She then delves into the most troubling moral dilemma in this scenario: What happens to the generation prior to the lucky cohort with eternal life? What happens when these folks, the last mortals, come face-to-face with the immortals and fully realize the gravity of their loss? Their anguish, she imagines, would be acute.

Rini essentially asks: What happens when the last mortals come face to face with immortals and fully realize the gravity of their loss?
Rini essentially asks: What happens when the last mortals come face-to-face with immortals and fully realize the gravity of their loss?

“My aim is to show that dying is worse for the last mortals than for earlier generations. The advent of immortality actually worsens the lives of those who fall closest in never reaching it,” Rini explains.

Rini is the perfect person to dive deeply into this issue. Her work analyzes research from the social sciences, especially cognitive science and sociology, and through this lens, she determines then investigates key philosophical questions. She believes we cannot understand our individual moral decisions without also understanding how we relate to those of others.

Biomedical breakthroughs have got us this far

In the article, Rini first reminds us of the ever-expanding lifespan of Western civilization: If you were born in 1900, your lifespan was, on average, 47 years; if you were born in 1950, it was 68; if you were born today, you could possibly expect to see your 100th birthday. The human lifespan has so expanded that if you are currently under the age of 40, then you can plan to meet young people who will live to see the year 2157, Rini says.

Rini suggests that biomedical advancements could, theoretically, extend human life to infinity

This would be, of course, the result of consistent biomedical advancements, including vaccinations, new cancer treatment, transplants and much more. Medical research is also shifting from acute conditions, such as the flu, to chronic conditions including heart disease and diabetes – getting to the root of some of today’s most common causes of death. Furthermore, aging is largely determined by genes, which can be manipulated, Rini points out. This opens another avenue for a limitless lifespan.

Rini ferrets out the most disturbing moral question

Regina Rini
Regina Rini

Now comes the hard part. Rini considers the situation, the possibility of mortality, and ferrets out the most disturbing moral question within it. She asks: “What if this [eternal life] all happened sooner rather than later?” She throws out a date – 100 years from now – and suggests that anyone alive in 2119 is likely to live for centuries, even millennia, possibly forever. (One caveat of immortality is that, given statistics about deathly accidents, sooner or later all “immortals” would eventually die in some form of an accident.)

But what about those who just about make it to this hypothetical date of 2119, when immortality is possible? Rini elaborates on this conundrum: “What would it mean to realize that you very nearly got to live forever, but didn’t? What would it mean if we were increasingly forced to share social space with young people whose anticipated allotment of time massively dwarfs our own?”

The agony of nearly making it to eternity, when surrounded by those who’ve effortlessly achieved this simply by the date they were born, is profound. She elaborates: “It’s one thing to imagine whippersnappers coasting into the next century. It’s another to know many will see the next millennium. The proportions are terribly imbalanced, and their distribution arbitrary. This is a sure recipe for jealousy. The last mortals may be ghosts before their time, destined to look on in growing envy at the enormous stretches of life left to their near-contemporaries. In one sense, it will be the greatest inequity experienced in all human history.”

What does immortality mean, and do we really want it?

Switching gears to consider the life of the immortals, Rini next considers if an endless life is something that people would genuinely want. In most fiction works, this is shown to be boring, tedious and meaningless. The film Groundhog Day with Bill Murray is a good example of this, as the lead character repeatedly wakes up to the same, inescapable day.

Rini also points out that if no one died, rampant overpopulation would certainly affect quality of life in a catastrophic way. Here, she unearths the fundamental human predicament: We may want to live forever, and do things to extend our lives, like eating right and not smoking, but the question of whether eternal life would be a blessing is unclear.

Rini’s article in the Times Literary Supplement is an accessible and hugely compelling read. She pushes through to the nucleus of moral questions, effortlessly drawing from a repertoire of thinkers from Greek philosophers Epicurus and Diogenes to the Roman Stoic Seneca, from feminist existentialist Simone de Beauvoir to J. R. R. Tolkien [Lord of the Rings], with an interesting fictional tangent about Sigmund Freud and an iPhone. Rini is an exceptional philosopher and thinker who, with everything she writes, takes readers on a veritable roller coaster ride of highly charged moral dilemmas.
