  • The hippocampus, a part of the brain essential for memory, has long been known to "replay" recently experienced events. Previously, replay was believed to be a simple process of reviewing recent experiences in order to help consolidate them into long-term memory. However, researchers have discovered that the replay function of the hippocampus is actually a much more complex, cognitive process.

  • When economists first started playing this game in the early 1980s, they assumed that this elementary exchange would always generate the same outcome. The proposer would offer the responder approximately $1⎯a minimal amount⎯and the responder would accept it. After all, $1 is better than nothing, and a rejection leaves both players worse off. Such an outcome would be a clear demonstration of our innate selfishness and rationality.

  • The X’s marked areas where Kiehl had discovered abnormally low grey matter density in Dugan’s brain. In a curious meeting of law and neuroscience, those X’s would help jurors decide whether he should be executed or sentenced to life in prison. Did the way Dugan’s brain had developed leave him spring-loaded for violence? Or had he chosen freely when he abducted, raped and killed a 10-year-old girl in 1983?

  • A dose of the "trust hormone" oxytocin may help bring some autistic people out of their shell. Patients with the condition usually have a hard time interacting with others, but when they inhaled oxytocin in a new study, they began looking at people in the eye and recognizing social concepts like fairness in a computer game. Although the results are preliminary, the work could lead to drugs to treat a variety of social disorders, including schizophrenia and anxiety,

  • the basic shot structure of the movies, the way film segments of different lengths are bundled together from scene to scene, act to act, has evolved over the years to resemble a rough but recognizably wave-like pattern called 1/f, or one over frequency — or the more Hollywood-friendly metaphor, pink noise. Pink noise is a characteristic signal profile seated somewhere between random and rigid, and for utterly mysterious reasons, our world is ablush with it.
