One cold morning last week, as I was out to pick up our newspapers, a group of perhaps 250 starlings took off from a neighbor's trees, rose as a mass, wheeled a couple of circles in the air over the trees and settled in other trees nearby. There were no predators in evidence, so iIt was not clear what made them fly or how they decided when and where to land.

"Trick or Treatment" is a critical (very critical) examination of several varieties of alternative medicine. I was surprised to see Simon Singh as lead coauthor of a book about health because I know him as author of a book about math, "Fermat's Enigma", that I recommended in December of 1999. I thought it was the best science/math book of that year.

Imagine a highly reliable cancer test. It detects 95% of a certain type of cancer, and has a "false positive" rate of only 1%. This test is used on a population in which this type of cancer occurs in 0.5%. One day your doctor tells you that you have tested positive. What is the chance that you are actually sick? Surprisingly, it is only about 32 percent!

When I saw this new book on the subject of evolution, I thought it would probably be one side or the other of the very tired evolution/creationism-"intelligent" design debate.

You won't find titillation in this book about sex and reproduction. These two one-act plays are intended by their author, one of the "fathers of the Pill" to prompt discussion of the many ethical questions posed by the divorce between act of sex and human reproduction.

Arthur Kornberg won the Nobel Prize for Physiology or Medicine in 1959, and just recently passed away (October, 2007). When his three sons were small, he used to tell them stories and poems about the "germs" he was studying. The subsequent generation of grandchildren came along, catalyzing a whole new batch of poetry and tales.

One of my picks last year was the frontal attack of an atheist scientist on religion. It was Richard Dawkins' popular "The God Delusion". This month, my choice is a respectful and conciliatory appeal by entomologist E. O. Wilson for common cause between religion and science in the preservation of what is left of Eden.

You may remember Elizabeth Kolbert as author of the extensive New Yorker series on climate change that was Hal's Pick in May of 2005. She also wrote about the ways in which ice core samples disclose the history of the atmosphere; that article was Hal's Pick in January of 2002.
