That selective reading by cells, he adds, allows them to flower and function differently, ending up, say, as muscle or liver cells: “The technique allows you to go neuron by neuron, and see what ...

This suggests that brain differences may have affected survival during the mass extinction that wiped out all nonavian dinosaurs. Credit Christopher Torres / The University of Texas at Austin ...
