As runners set their New Year’s resolutions, Simon Fraser University researchers have dug thousands of Strava posts to map the emotional highs and lows of running and see what makes people stick with it.

The first-of-its-kind study has unearthed what makes a run feel joyful—or miserable—by analysing more than 3,200 Strava posts from Metro Vancouver runners between 2010 and 2021. Researchers say the findings could help cities design safer, more inclusive spaces that encourage physical activity.

As winter heating costs rise, new research from Binghamton University, State University of New York reveals a cold truth.

Nicolas Sommet, a social psychologist and research manager at the LIVES Centre at the University of Lausanne, and his team have published the first social science meta-analysis in the prestigious journal Nature (on 22 January in its print edition). Their conclusions — based on 168 studies covering more than 11 million participants from around the world — challenge the widely held belief that economic inequality is detrimental to well-being and mental health.
