It’s true that as we grow older, many aggravations that we used to take seriously seem to lose edge. Some of us, however, become grumpy, cantankerous oldsters. It’s generally recognized that a positive outlook on life has a favorable effect on general health. If that’s correct, then the “mellow oldsters” might have been a self-selected […]

Timely suggestions Clock time has long been out of step with the heavens (“To Leap or Not to Leap,” SN: 4/22/06, p. 248). Since the adoption of time zones in the 19th century, we have accepted disparities of as much as 30 minutes at the edges of the time zones (more in some cases since […]

The possible link between coffee consumption and reduced occurrence of alcohol-related cirrhosis seems worthy of further study. Although the beneficial effect may be due to any of a variety of coffee ingredients, it would seem rather straightforward to investigate a correlation in caffeinated and decaffeinated beverages.

With the known link of asbestos to lung cancer, the new finding mentioned in this article that many other diseases can be caused by asbestos only serves as fodder for litigation, clogging of our legal system, and, unfortunately, more enrichment of trial lawyers instead of asbestos victims.

Cuts on the bias After taking some of the bias tests, I am very skeptical (“The Bias Finders: A test of unconscious attitudes polarizes psychologists,” SN: 4/22/06, p. 250). Since the major tool is speed of reaction, and since my eyes are not too good now, the results were very curious and probably totally unreliable: […]

In this article, Alycia Weinberger says, “The discovery of a disk around the planetary-mass companion to 2M1207 should be a bit of a relief to planet-formation theorists” because it casts doubt on the object being a planet. But wouldn’t our early solar system have been composed of at least two planets, Jupiter and Saturn, that […]

Tiktaalik may not have left the water by choice, to avoid predators, or to get more oxygen. Instead, it might have found itself left behind on a muddy floodplain each time waters receded with the tide.
