About this episode

When an artery becomes blocked or damaged, a mechanical scaffold called a stent is often implanted into the vessel to improve blood flow. However, metallic stents can cause re-narrowing at the sites where they are implanted. This process is known as restenosis, which can lead to lethal complications. Dr York Hsiang, Professor of Surgery at the University of British Columbia, and his team use microengineering techniques to develop novel stents that can better detect restenosis, and treat it earlier when it occurs.

Prof. Alex Vitkin | Seeing the Invisible: How Polarized Light Contributes to Our Understanding and Detection of Cancer

Light is something we encounter every day, so familiar that it rarely inspires a second thought. Yet beneath its apparent simplicity lies a remarkable complexity. Light can carry information in its brightness and color, but also in its polarization and phase, subtle properties that describe how its waves oscillate and interact. For decades, these hidden dimensions of light have remained largely untapped in medicine. Now, a growing body of research is beginning to reveal their extraordinary potential.

Dr. Cini Bhanu | When Standing Up Knocks You Down: Why Postural Hypotension Goes Unnoticed

Imagine standing up from a chair and feeling a sudden wave of dizziness, as though the floor beneath you has shifted. For many older adults, this is more than just an occasional inconvenience, it’s a recurring problem linked to a condition called postural hypotension. Despite being relatively common, postural hypotension is surprisingly overlooked. It affects between 20-30% of older adults living in the community, yet is officially recorded in only about 1% of patients’ medical records in general practice. That gap is vast, and it carries real consequences: increased risks of falls, strokes, heart problems, and reduced quality of life.

Dr. Gebrekrstos Negash Gebru | On the Front Lines of a Pandemic: Sierra Leone’s Field Epidemiology Training Program Success Story

In early 2020, as headlines around the world warned of a fast-spreading new virus, Sierra Leone watched with a mixture of concern and determination. The country had not forgotten the devastating Ebola outbreak of 2014 to 2015, which had exposed painful weaknesses in disease detection, surveillance, and emergency response. That experience left deep scars, but it also sparked reform. When COVID-19 began its global sweep, Sierra Leone faced the crisis with a stronger foundation than many might have expected.

Prof. José Ignacio Nazif-Muñoz | Quand la chaleur rencontre la route: comment la hausse des températures modifie la sécurité routière en milieu urbain

Lors d’une journée d’été étouffante, la plupart d’entre nous remarquent les effets évidents de la chaleur. Nous nous sentons plus lents, plus irritables et impatients d’échapper au soleil. Ce qui est moins visible, c’est la manière dont ces mêmes conditions modifient discrètement notre comportement au volant. Une étude récente dirigée par le professeur José Ignacio Nazif-Muñoz de l’Université de Sherbrooke, en collaboration avec le professeur Jose Guillermo Cedeño Laurent de l’Université Rutgers, explore ce lien caché, révélant comment les vagues de chaleur et les modèles thermiques urbains influencent la sécurité routière dans cinq villes du Québec. Les résultats rappellent opportunément que le changement climatique n’est pas seulement un enjeu environnemental, mais aussi une question de sécurité publique qui touche la vie quotidienne de manière inattendue.
