Xtractaurs These dinosaur action figures have a virtual life of their own. Players use a “DNA-extraction gun” to capture a creature’s genetic blueprint and download it to a Mac or PC. Then they can mix and match the genetic components to create new hybrids—combining, say, the teeth of a T. rex with the spiked tail of a Stegosaurus. Dino-obsessed friends can even compete in a cyberworld that blends fantasy with a dash of loosely interpreted science. Away from the screen, the models of pterosaurs, ceratopsids, and other figures are colorful, movable, and fairly realistic. A starter kit (extraction gun, CD, and T. rex) costs $20; additional figures are $9 each. Lindsey Konkel

NOVA: Why Do We DreamPBS, Tuesday, October 20, at 8 p.m. (ET?)This captivating one-hour special highlights the latest that science has uncovered about the purpose and meaning of dreams.

A mix of personal stories (a woman dreams repeatedly about an abusive past relationship) and fascinating study results (a test subject suddenly excels on a ski-racing simulator? after dreaming about snow) keep the show moving at a lively pace. The take-home lesson: The dreamworld affects both mental health and problem solving in our waking lives.
