Next up, the science of monsters. Like most myths, there are some real-world phenomena behind the stories. Take vampires, for example. Let me read you a passage from Bram Stoker's "Dracula," where Professor Van Helsing describes the monster.

Earthquakes, terrorist attacks and muggings have all scared people to death. Sporting events, too, sometimes cause frenzied fans to drop dead. Neurologist Martin Samuels of Brigham and Women's Hospital explains how positive or negative excitement can lead to a heart-stopping surge of adrenaline.

Thirty years ago, the primatologist Frans de Waal published Chimpanzee Politics, a wonderful bombshell of a book that revealed the depth of chimpanzees' social complexity. Based on long-term observations at Arnhem Zoo in the Netherlands, many of de Waal's descriptions match comfortably with what chimpanzees in the wild have since been observed to do.

A study linking the artificial sweetener aspartame — which is found in lots of diet sodas — to a possible cancer risk in people was set to make a splash earlier this week. But shortly before the paper was published, in a very unusual move, the scientific leaders at the hospital released a statement saying the findings were too weak to promote.

Some of the weirdest animal behavior is about romance. That's especially true with birds — they croon or dance or display brilliant feathers to seduce the reluctant.

This sort of sexual display apparently has a long pedigree: There's now new evidence that some dinosaurs may have used the same come-on.

The source is a kind of dinosaur that was built like a 400-pound ostrich. It lived about 75 million years ago and is called ornithomimus, meaning "bird mimic."

Both presidential candidates have all but ignored climate change during this election season. Mitt Romney would not make it a priority if he were president.
