The March for Science is kind of a funny thing.
The organizers insist that the event will be nonpartisan. But it will feature many of the trappings of a political march — signs, chants and speakers riling up the crowd.
The situation presents a quandary of sorts. Being a scientist requires objectivity....(image)

Now here’s a contagion that might not be so bad to encounter. A new analysis of the running habits of about 1.1 million people reveals that exercise is indeed contagious — though its communicability depends on who’s spreading it.
The findings, published in the journal Nature Communications, also...(image)
