Pain is often under-diagnosed and under-treated among older adults, especially those with dementia, who have trouble communicating their discomfort. Additionally, approximately 60 per cent of older adults with dementia suffer a fall each year. Dr. Babak Taati is among a group of researchers in Canada aiming to tackle these problems using computer vision and artificial intelligence (AI).   In this episode of Behind the Breakthrough, we learn how Dr. Taati’s work involves using ambient monitoring systems to assess and analyze the movement and facial expressions of older adults to detect signs of pain and predict the likelihood of future falls, all while they go about their daily lives. He also discusses the ethical considerations of ambient monitoring techniques, from privacy concerns to working to eliminate ageism and ableism in the technology used.

Nanoscience is the study of the small, the really small. Consider this; a nanoparticle can be as small as one-billionth of a metre. Nanotechnology in medicine is having a moment, with the profile and perception of the approach raised since it played a role in the development of mRNA COVID-19 vaccines. But for Dr. Gang Zheng, the science of the very small and how it can be harnessed in cancer care has been a pursuit of passion for years. In this episode, Dr. Zheng talks us through his development of a unique nontoxic nanoparticle, a porphysome, made by combining lipid or fat particles with a compound derived from pacific algae.  This so-called Swiss army knife of nanoparticles has the potential to significantly improve the way cancers are detected and treated, from targeted drug delivery to ablation of the tumour from within using light. Dr. Zheng also discusses the importance of collegiality and collaboration in science and the pride he takes in mentoring and training the next-gen of doers and thinkers, who in turn have dubbed themselves ‘Gangsters’ in his honour. And how he remains driven by one goal above all others – to make a positive impact on cancer patients' lives.

The COVID-19 pandemic shocked everyone around the world - even those who study viruses such as Dr. Jordan Feld. In 2015, Dr. Feld led a groundbreaking international trial that made the breakthrough discovery of a pill that cures Hepatitis C. When the pandemic hit, he shifted gears and led another pioneering investigation into a treatment for the Coronavirus using Interferon Lambda. After a successful phase one and two trial, it is currently in phase three with more patients enrolled. Compounding the urgency for COVID-19 treatments, Dr. Feld was juggling the approval process for his trial with the birth of his third son. He touches on the impact the pandemic had on research, how his team maintained a safe environment during the trial and what it means to be a mentor.

Chemotherapy works by essentially poisoning cancer cells, which grow more quickly than most normal cells, and thus absorb a lot of the toxic drugs. It has been regarded as a standard treatment in cancer care for decades, and can work wonders, especially early in a person’s treatment. But over time, these drugs may stop working. Dr. Catherine O’Brien and her team at the Princess Margaret Cancer Centre were trying to figure out how cancer cells apparently become resistant to chemotherapy when they made the discovery that the cells can enter a state akin to hibernation to avoid the toxic onslaught of the drugs. In this episode of the Behind the Breakthrough, Dr O’Brien discusses how her team made this groundbreaking discovery and how it may lead to unique therapeutic opportunities for patients in the future. She also discusses the importance of making connections between different scientific disciplines, and how a Grade 10 career day spent with a female surgeon inspired her to pursue a career in surgery herself.

In this episode of ‘Behind the Breakthrough’ Princess Margaret Cancer Centre scientist Dr. Michael Hoffman explains how he leverages the power and speed of computers to understand the origins of cancer. He says cancer is a disease of the DNA –the genetic code that determines our individual characteristics. Essentially, our DNA acts as a program telling our cells what to do. In the case of cancer the wrong program gets run and cells divide in an unrestricted manner. The goal of Dr. Hoffman’s lab is to determine if there is a way of predicting when the wrong program gets run –before it ever happens. We also learn that from age 4 Dr. Hoffman was in awe of the magic of computers, and how he turned his love for computers into a career in the emerging field of computational biology. He also speaks to the critical importance of training the next generation of cancer researchers, and how he views Twitter as a virtual meeting place for scientific exchange

In the battle to defeat cancer, award-winning UHN researcher Dr. Mathieu Lupien is a modern-day version of the Bletchley Park World War Two codebreakers. Dr. Lupien searches the human genome, trying to crack the origin of how and why cancer starts. He knows deciphering that enigmatic code is one of the keys that will lead to a cure for cancer. He explains how the human genome is like a road map to the inner workings of what makes us, well, us—and the many ways cancer disrupts that journey, and why researchers are now looking at so-called “junk DNA” for the source to cancer’s origins. Dr. Lupien also talks about the Terry Fox loonie he carries in his pocket at all times as a reminder of the commitment and importance of the work done in his lab, how a line in a TV show he watched as a child in Quebec has fuelled his research career,” and his advice for kids who want to go into science.
