In this episode, Matheus guides us over a small portion of the peer-reviewed literature on the psychology of habits. We discuss some scientifically proven methods to help you prevent bad habits from firing such as environmental design. We also discuss the impact that motivation has on the process of breaking bad habits, and how overachievers become as productive as they are.

In today's episode, Philippe tells us about how scientists studying a cell-stress management protein got into a lengthy argument over mistakes found in their published work. This is a great example of how science has the ability to correct its own mistakes over time.

At the beginning of every year, people are always talking about their new year's resolution and about adopting healthy habits. But how exactly do you develop new habits? In this episode, Matheus guides us through some of the peer-reviewed literature about habit formation. What are habits? What do you need to form them? And how are scientists studying habits today?

Matheus has had several sleep paralysis episodes throughout his life. In this episode, Matheus and Phil discuss the science behind sleep paralysis. What is happening in the brain during a sleep paralysis episode? What are some scientifically proven ways to prevent sleep paralysis? Are there any tricks to snap out of it and to stay calm if it ever happens to you?

Cara Hawei is a M.Sc candidate at McGill University researching the application of induced pluripotent stem cells in personalized medicine. Her research focuses on characteristics of dilated cardiomyopathy, a disease of the heart.

In this episode we discuss how cells from the blood can be turned back into stem cells so that these new stem cells can be turned into heart muscle cells for Cara's Studies. We also go into further detail on how Cara is developping assays to measure features of dilated cardiomyopathy, and how her research will allow for personalized treatments in different patients.

Younes Rhazi has a bachelors degree in politics and economics. He's now completing a master's degree in international and public affairs at Université de Montréal.

In this episode we discuss the pros and cons of universal basic income (UBI). Instead of giving a selling pitch, Younes discusses what we should think about before developing new policies and how science, empirical data, and pilot projects can be used to build confidence in the process of policy making.
