I know some people who carefully shield their bodies from the sun with sunscreen and clothing, and their skin is extremely pale. But if tanning acts as a protector, is it actually safer to maintain a “healthy” tan? Chris EsseBeverly Hills, Calif. Scientists continue to debate this question vigorously.

I would guess that a rock measuring 1 kilometer across, landing near New Zealand 500 years ago, would have done much more than create a tsunami 300 to 500 feet high. Was the object 1 km across before encountering Earth’s atmosphere? Don ArthurNorth Coventry, Pa. Yes. The object’s estimated size is before it hit the […]

Your article describes a great theory in a theoretical world. The purpose of a coin toss is to determine an outcome in the real world, however. Did the guys doing the various analyses factor in the effect of the coin bouncing on the ground or being fumbled in an attempted catch? Ed EiermanRomney, W.Va. The […]

It’s tough in there In the arts, we say that material, such as paper, that deteriorates readily because of its composition (“News That’s Fit to Print—and Preserve,” SN: 1/10/04, p. 24: News That’s Fit to Print—and Preserve) has “internal vice.” I suppose that could be said of newspapers on several grounds.

On an ecological scale, inflammation is an acute response to environmental insult, while fat is a chronic response, through its role in sequestering toxins. Perhaps the new research reveals a genetic program to arm the body’s defenses both […]
