Michael Rudnicki has been studying muscle biology for a long time… all the way back to his days as a graduate student. In this time, he’s contributed greatly to our understanding about muscle formation and the molecular “switches” that guide a stem cell’s decision to develop down the pathway towards muscle or brown fat. You may recall this study on the gene responsible for triggering the production of brown fat; it was the most popular story on EurekAlert! in 2013.

If you’re interested in muscle biology and stem cells, you might want to have a look at what Dr. Rudnicki is up to now. Muscular Dystrophy Canada recently interviewed him about his past, present and future research — to skip the info about grants and get to the “bare” facts, jump ahead to 2:28.

Our regular feature, Right Turn, showcases the “lighter” side of stem cells and regenerative medicine. Every Friday, we will bring you cartoons, photos, videos and other content that may be just as thought provoking as the written submissions that you are used to finding here, but they definitely won’t be blogs.

As always, we welcome your feedback and we also welcome suitable submissions. Be creative! Use the right (!) side of your brain. Make us laugh! Let’s see if we can make this new direction a positive one for all of us. Send your submission to info(at)
