ENCORE  We all have worries. But as trained observers, scientists learn things that can affect us all. So what troubles them should also trouble us. From viral pandemics to the limits of empirical knowledge, find out what science scenarios give researchers insomnia.
But also, we discover which scary scenarios that preoccupy the public don’t worry the scientists at all. Despite the rumors, you needn’t fear that the Large Hadron Collider will produce black holes that could swallow the Earth.
It’s Skeptic Check, our monthly look at critical thinking … but don’t take our word for it!
