Naturally Dangerous: Surprising Facts about Food, Health, and the Environment

Mon, 10/01/2001 - 01:00 -- Hal Harris

Professor James Collman of Stanford University has provided an excellent resource for all of us who try to help our students and the general public to discriminate between valid science and the bogus "scientific" claims that pervade television, the Internet, the grocery store, and especially the "health food" store.

Drugstore Athlete

Sat, 09/01/2001 - 01:00 -- Hal Harris

For a long time, it could be said that with some validity that drugs not help athletes perform better. That is no longer the case. It is could increasingly difficult to assure that amateur athletes, even high school athletes, are not training and competing with the aid of testosterone and its precursors, or erythropoetin.

Transforming Matter: A History of Chemistry from Alchemy to the Buckyball

Wed, 08/01/2001 - 01:00 -- Hal Harris

I've been reading a lot lately about alchemy, and was therefore delighted to find a new book on the history of chemistry (that includes some on alchemy), just published by Johns Hopkins University Press. Trevor Levere takes on the impossible task of chronicling the developments in chemistry from its beginning to the present, in only a little over 200 pages.

Nitric Oxide and the Control of Firefly Flashing

Mon, 07/02/2001 - 02:00 -- Hal Harris

As a physical chemist, I was amazed when it was discovered that the diatomic free radical, nitric oxide (NO) was intimately involved in the transmission of neurological information in mammals. Now a group led by Barry Trimmer at Tufts University has demonstrated that it is the key that turns on bioluminescence in fireflies.

The Mosquito Killer

Sun, 07/01/2001 - 01:00 -- Hal Harris

What do you think of when someone mentions DDT (dichloro-diphenyl-trichlorethane)? Chances are that your mind immediately goes to the damage the use of this chemical has done to bird populations, Rachel Carson's "Silent Spring", and the effort to ban or control its use.

Off the Planet: Surviving Five Perilous Months Aboard the Space Station Mir

Wed, 05/02/2001 - 02:00 -- Hal Harris

The word "Surviving" should probably be underlined in the title of this first-hand account by an American astro/cosmonaut of his experiences aboard Mir. There is precious little science in this book, but a great deal about living at the mercy of technology and Russian bureaucracy.

The Shaken-Soda Syndrome

Tue, 05/01/2001 - 01:00 -- Hal Harris

Try this! Take two identical cans of soda (or some other beverage). Roll then down a slight incline to confirm that they roll at about the same speed. What do you think will happen if you shake up one can and roll them again? Make a prediction. Then try it. Have your students do it. Develop hypotheses and test them. This is a terrific experiment that anyone can do.
