What to do when traditional mechanistic approaches no longer work

Many complex behaviors have stubbornly resisted mechanistic explanations. Deciphering them will require new approaches—and perhaps a new concept of “understanding.”

Nuclear location helps control gene activity during brain development

A study of developing human brain tissue suggests that genes switch on more strongly when they move from the nucleus’s edge toward structures that contain proteins involved in making and processing RNA.
