Philip Benfey, Professor of Biology, Director of the Duke Center for Systems Biology and contributing author of the 2012 Annual Review of Plant Biology, talks about his article Control of Arabidopsis Root Development. In this lecture, he discusses the cellular and genetic mechanisms that underlie root formation in Arabidopsis thaliana, from embryonic roots to lateral roots. He also describes how the roots react to environmental stress, such as high salinity. Finally, he explains how molecular genetics, genomics, and systems biology made it possible to control root development.
Michael Tomasello, of the Department of Developmental and Comparative Psychology at the Max Planck Institute for Evolutionary Anthropology, discusses his article for the 2013 Annual Review of Psychology, titled "Origins of Human Cooperation and Morality." In this video, he shares footage of chimpanzees and of toddlers collaborating, showing that while cooperation exists among other primates, it is much more developed in our societies, even among very young humans. Children have a stronger sense of egalitarianism, and do a better job of suppressing their self-interest when they cooperate on a task. Not only that, they are capable of demonstrating norm-based group-mindedness, another form of collaboration.
