La morale sociale ne saurait se passer de punitions, infligées par les pairs lorsqu’un individu enfreint les règles. Mais qui punit ? Pourquoi ? Et pour quels bénéfices ?
Standing up for what’s right can come with a cost to the individual – but also a benefit.

A fracking well injects large volumes of water, chemicals and sand to fracture rock.
Fracking fluids in Marcellus shale have contaminated groundwater but new study finds that the source is likely from surface spills, not leaks from underground wells.
I knew that brain was yours.

Typically, researchers pool a bunch of brain scans to figure out the average way brains handle certain tasks. Instead, could they pick out individual brain profiles from a stack of 126 people's scans?
