    Hand and Brain

    Get a handle on primate handedness research and its bearing on brain function at a Web site run by anthropologist M.K. Holder. Participate in ongoing research and listen to various primates sound off, from a screaming chimpanzee to a belching mountain gorilla. Go to: http://www.indiana.edu/~primate/index.html

    I object to the glib use of the phrase “time reversal” in this article. Time is a sequential history of events and is not reversible. What the researchers are accomplishing is a clever resequencing of events, roughly analogous to playing a strip of movie film backwards, an event that I’m sure you will agree occurs […]

    GREAT LION OF LA BREA Bigger by a fourth than the proudest lion that walks the veldt today were the tallest of the great lions of California a hundred thousand years ago. Rivaled in size only by the short-faced bears whose bones have been found with theirs in the La Brea tar-pits, they could confidently […]

    Your article ends with the claim that “a color-blind person and a noncarrier have no chance of having a color-blind child.” Yet as I recall from basic biology class, color blindness is considered a prime example of a sex-linked trait, which makes the above statement untrue. Carried on the X chromosome, the trait would manifest […]

    This article is somewhat misleading. We physicians long ago learned that blocking the enzymatic process (with Antibuse) helps alcoholics. The news is that increases in acetaldehyde in saliva have “possible local carcinogenic action.” Malcolm A. Sowers Castro Valley, Calif

    I was dismayed to see you publish an unsubstantiated and highly misleading claim that welfare “reform” is not harming children. The study dealt with the atypical welfare mothers able to find sustainable employment. For them, I don’t doubt that having enough money rather than too little would be an improvement. Unmentioned are the many unskilled […]

    You state in this article that in the last century, the average global temperature has risen about 0.6C. I suspect that most of the sensors in use today are not in the precise locations of thermometers 100 years ago. Also back then, there were wide areas of the globe that were probably not being monitored […]

    The July 22 cover, “Sticker shock,” and the related article say that the powerful forces that arise at the surface of micromachines weren’t expected. Any skilled machinist who has used Johannsen gauge blocks in measuring and checking his work would not be surprised at all. These blocks are stacks of hardened steel rectangles with highly […]

    I beg to differ with the quote, attributed to Ethan Temeles in this article: “This is the first really unambiguous example of ecology playing a role in the morphological differences between the sexes.” The statement exhibits the annoyingly common practice among zoologists to think and generalize as if only animals (and, even worse, only vertebrates) […]

    FISH OF DIFFERENT “FEATHER” OFTEN FLOCK TOGETHER Game herds of the African veldt have long been a marvel to travelers because of the extraordinary variety of animals seen together: zebras, gnus, antelope of many species, even elephants and ostriches, mingling in a wonderful patchwork quilt of moving life. Only lions and other predators are outsiders […]

    TWISTER POSES Perhaps the finest photograph ever taken of a tornado–certainly at any rate a most unusual one–was obtained by Ira B. Blackstock, a Western railroad executive, at Hardtner, Kansas, on Sunday, June 2, 1929, at about 4:30 p.m. Mr. Blackstock let the windy monster approach as closely as he dared, standing with one foot […]
