The primitive form of crayfish anxiety probably shares some evolutionary origins with the more developed human form, although the ways in which this emotion has shaped each species remain unknown.

A number of exciting, family-friendly activities are planned for Washington, D.C. and across the nation when the first-ever USA Science & Engineering Festival opens next month. As a founding partner helping to make the event possible, AAAS has provided planning and promotional assistance and will host two festival activities.

The main festival activities will take place on the National Mall and surrounding areas from 11-24 October, with free events ranging from exhibits to lectures to stage shows.
