Here is a scientific look at zombies - and the ultimate guide to how the other half lives (or not). How fast and far would a zombie infection spread? What would a nutritionist say about an all-brain diet? Why are the undead so pissed off? Here are the answers to all of your essential zombie questions (you know you've asked them), with a lively, science-based exploration of every aspect of the undead.

The latest and most bitterly contested battle in the culture war is the controversy over Darwin and intelligent design. But much of what you've heard about it is wrong. Jonathan Wells, a battle-hardened veteran with doctorates in biology and theology, sets the record straight.

Ignác Semmelweis is remembered for the now-commonplace notion that doctors must wash their hands before examining patients. In mid-19th century Vienna, however, this was a subversive idea. With deaths from childbed fever exploding, Semmelweis discovered that doctors themselves were spreading the disease. While his simple reforms worked immediately - childbed fever in Vienna all but disappeared - they brought down upon Semmelweis the wrath of the establishment, and led to his tragic end.

Siroccos, Santa Anas, chinooks, monsoons...the wind has as many names as moods. Few other forces have so universally shaped the lands and waters of the earth, the plants and animals, the patterns of exploration, settlement, and civilization. Few other phenomena have exerted such a profound influence on the history and psyche of humankind. Wind touches all of us every day of our lives, yet remarkably little has been written about it except as a component of the weather.

We inherit mechanisms for survival from our primeval past - none so obviously as those involved in reproduction. The hormone testosterone underlies the organization of activation of masculinity: It changes the body and brain to make a male. It is involved not only in sexuality but in driving aggression, competitiveness, risk-taking - all elements that were needed for successful survival and reproduction in the past. But these ancient systems are carried forward into a modern world.

It seems likely that scientists will someday discover how life can emerge on habitable planets like the early Earth and Mars. In Origin of Life: What Everyone Needs to Know, David W. Deamer has written a comprehensive guide to the origin of life that is organized in three sections.
