Birds make decisions faster than we do, rewriting DNA’s history, and combining science and poetry

Sarah Crespi and Tim Appenzeller discuss a resurfaced Rosalind Franklin X-ray photograph and its implications for the history of DNA structure. Elah Feder then speaks with Andreas Nieder about experiments comparing the speed of decisions in crows and primates, considering neural mechanisms and evolutionary advantages. Phil Levin and David Hassler discuss collaboration between ecological research and poetry, with a reading by Lara Volski.
