Acid Tongues and Tranquil Dreamers: Eight Scientific Rivalries that Changed the World

Many people have difficulty understanding the motivation of scientists for precedence and the recognition it brings. While there are monetary incentives for some of the protagonists in "Acid Tongues", it is more often pride and the acceptance of one's ideas that drove the rivalries of Newton vs. Leibniz, Edison vs. Tesla, Crick and Watson vs. Pauling vs. Franklin and Wilkins.

Generation of a Bacterium with a 21 Amino Acid Genetic Code

Even those of us whose whose biochemistry is a little shaky are likely to know that there are twenty amino acids that form the building blocks of proteins in life on earth. Now even that simple factoid is no longer absolutely true. A group of scientists headed by Peter G. Schultz of the Scripps Research Institute have created a new form of E.

Stuffed Animals and Pickled Heads: The Culture and Evolution of Natural History Museums

When I was a kid, my brother and I used to negotiate Saturday Los Angeles traffic on our bicycles in order to get to the Museum of Natural History of Los Angeles, where the great collection of dinosaur bones from the La Brea Tar pits were exhibited.

DNA as Destiny

We all know that, with the deciphering of the human genome as well as those of other animals, and of plants, that the future will bring a new level of understanding and control of our own heredity. But what can the present level of genetic testing provide? In this story, writer David Duncan has as much determined about his future as you can learn with current technology.

Chemical Misconceptions - Prevention, Diagnosis, and Cure (2 Volumes)

I usually avoid writing in this space about materials that one might use directly in the classroom, since I am trying encourage teachers to expand their scope. However, this two -volume set recently published by the Royal Society of Chemistry is enough to make me change the rules.

The Odds of That

When nearly a dozen scientists, all in some way associated with research on biotechnology, die within a year of the 9/11 attacks, can it be coincidence? Yes, says Lisa Belkin, author of this excellent article on one of the constants of pseudoscience, the attribution of "cause" to random events.

One Good Turn: A Natural History of the Screwdriver and the Screw

It goes without saying (amongst males, at least), that one can never have too many tools. Most of us probably have more screwdrivers than any other tool, both because of their utility and their high vapor pressure (like my reading glasses), and so one needs to buy more in order to make sure that one will be available when needed.

Relativity and the Global Positioning System

An ideal companion to "The Universe in a Nutshell" is this article by Neil Ashby, a Professor of Physics at University of Colorado - Boulder. Hand- held GPS devices have become standard equipment for boaters, hikers, and technology junkies. It is now taken for granted that one's position on the earth can be obtained within a few seconds, accurately, and free.
