Why Evolution is True and Why Many People Still Don't Believe It (Jerry Coyne, 2012)

Pardis Sabeti and colleagues describe their analysis of human sequence data from the 1000 Genomes Project to reveal hundreds of potential adaptive variants. In a second study, the authors engineered m...

TIM review on host-virus interplay in zebrafish

Jean-Pierre Levraud, Nuno Palha, and Pierre Boudinot discuss how zebrafish can be used as a model for studying viral infections and host-virus interactions. For more information, see the related revie...

Intestinal Tumorigenesis Initiated by Dedifferentiation and Acquisition of Stem-Cell-like Properties

Florian Greten and colleagues explain why enhanced Wnt signaling causes postmitotic (non-stem) cells to dedifferentiate and reacquire stem cell characteristics, enabling the cells to initiate tumorige...
