I do not know about the rest of your readers, but I do “hear” at least some low frequency sounds, but not with my ears. The nerves in my feet feel these vibrations and my brain parses the sounds to my flight-or-fright processor before I can process any conscious perception. Ray BryanSt. Paul, Minn.

In the arts, we say that material, such as paper, that deteriorates readily because of its composition has “internal vice.” I suppose that could be said of newspapers on several grounds. Lawrence Wallin Santa Barbara, Calif.

In this article, the statement is made that personal environmental exposures to volatile organic compounds (VOCs) are easily solved. The implication is that if you have a long commute and are thereby exposed to high concentrations of VOCs, you should just quit your job to avoid exposure. I find that completely absurd. Mark PalmerRichland, Wash. […]

I find the language in this article to be judgmental and unscientific. For example, “desert pavement and their biota are wounded by human activity” is neither artistic nor scientific. Such narrow, biased views of ecology have no place in a scientific journal. Boone MoraGarden Valley, Calif.

This article skipped one of the most significant methods for analyzing text for authorship. On March 11, 1887, Thomas Corwin Mendenhall reported in Science a straightforward method of plotting word length versus frequency. The beauty of this method is that it doesn’t depend upon the exercise of judgment on the part of the investigator. Donald […]

The conclusion does not follow from the data in this article. The possibility was not ruled out that the same inborn trait that causes fear of novelty also hastens aging. A cohort of novelty-averse rats should have been left stressfree to answer this important question. Tom PaskalMontreal, Quebec

This article speculated on the evolutionary origins of thermogenesis and observed how it predominates in ancient lineages of flowering plants like magnolias and water lilies. But thermogenesis goes back much farther than this, for it also occurs in cycads, nonflowering plants that arose in the Paleozoic. The male cones of some cycads, when mature, may […]

This article describes attempts to use ketones as a substitute for glucose when it’s unavailable to the brain because converted fats can’t penetrate the brain. Wouldn’t it be simpler to feed or inject glucose directly? Oliver H. WinnCorona del Mar, Calif. The researchers who conducted the study say that giving glucose might help in some […]

Your article uses the words “placebo therapies such as supportive counseling.” I think that people in the profession and people who have been paying for such therapy would disagree with the characterization. Also, the various permutations of treatment covered in the article didn’t include a very common one: drugs without any serious counseling. In such […]

This article describes the use of the mosquito-borne Sindbis virus to kill cancer cells in lab dishes and mice. It would be interesting to determine whether the human population of the Egyptian town of Sindbis exhibits a reduced incidence of certain cancers. Perhaps large-scale efforts directed toward elimination of the mosquito in populated areas are […]

Unfortunately your article got something wrong in describing the reshaping of aircraft surfaces. It states, “The recently retired supersonic commercial transport, the Concorde, tilted its nose downward for subsonic flight.” This is not the (whole) truth because the reason for this reshaping was not to reduce air drag, but to achieve a far-better view of […]
