I was truly devastated by the news from the Boston Marathon yesterday. This kind of senseless violence perpetrated at what has always been such a positive, peaceful, joyful gathering is just too horrible to describe. Scientific American is covering many aspects of this kind of event, from the wonderful behavior of fellow runners (acting against what psychology tells us), to the value of social media during the crisis. I have a post on why so many of the runners began to show signs of hypothermia after being diverted off the racecourse, and how runners and Bostonians helped each other. And today, I’m Running for Boston, and I hope you will run, walk, or otherwise locomote for Boston, too.
