Video tour of a game that helps children with anger issues handle their emotions

Researchers at Children's Hospital Boston develop a video game to help children with anger problems handle their emotions. See how it works.

Matthew Nock sits in his lab’s control room, where researchers record subjects’ behavioral and physiological responses during experiments. For example, they might measure whether people who engage in self-injury show greater emotional distress, in response to frustrating tasks, than people who do not. (Nock’s lab manager and a postdoctoral fellow are seen in the adjoining room through one-way glass.)

A skull session with human evolutionary biologist Daniel Lieberman in the fossil room at the Peabody Museum. Millions of years of natural selection have shaped the human head. From left to right: a Neanderthal; <i>Homo erectus; Homo habilis; Australopithecus africanus; Pan troglodytes</i> (common chimpanzee); <i>Homo sapiens</i> (human). “Gonzo,” a Neanderthal skeleton, stands in the back.

Hyman professor of chemistry Charles Lieber has created a transistor so small it can be used to penetrate cell membranes and probe their interiors, without disrupting function. The transistor (yellow) sits near the bend in a hairpin-shaped, lipid-coated silicon nanowire. Its scale is similar to that of intra-cellular structures such as organelles (pink and blue orbs) and actin filaments (pink strand).
