This article leaves us up in the air with this statement: “. . . since the traditional wine-making techniques still in use in southwestern France and Sardinia increase concentrations of polymeric procyanidins, he says, other vintners may soon adopt such methods.” As a home winemaker, I have to ask, Which techniques contribute to increasing procyanidins? […]

This article says that a planet so close to a red dwarf would be forced to “rotate in sync” with the star. Is this the same situation that causes the moon to rotate in sync with Earth? Ken BollersHudson, Colo. Yes. First, the larger body (the red dwarf) pulls the smaller body (the planet) slightly […]

If membership in a species is characterized by the inability to breed with members of another species, how can there be “animal species known to have arisen from crossbreeding with other species? Jeffry D. MuellerEldersburg, Md. Exceptions happen. Also, biologists argue about what defines a species. —S. Milius I suggest that the new species be […]

Your article made a common mistake in characterizing the mechanism of steroid-hormone receptors. These receptors are not “proteins on the cell surface” but rather, and uniquely, positioned intracellularly. Steroid hormones pass directly from the bloodstream to the cytoplasm, where they induce changes in the receptor proteins, enable movement into the nucleus, and activate specific genes. […]

Concerns vented “Venting Concerns: Exploring and protecting deep-sea communities” (SN: 10/7/06, p. 232) barely scratches the surface of the problem. What is stopping someone from gene splicing the disease of choice onto heat-loving bacterium? Something that can live near the 600°F of melting lead will certainly survive the standard hospital-sterilization process. D.J. KavaBeaumont, Texas The […]

Since when are “nanoscale” and “nanotech” interchangeable? Just because somebody uses something that is small doesn’t make it “nanotech.” Talcum powder is ultra fine too. Should we call it nanotech? I don’t think so. Adam HuntHuntington, W. Va.

This article explained how research was being done to find a way to get rid of head lice without the use of harsh chemicals. While the method mentioned might work, I found a much lower-tech approach. I tried a multitude of things to get rid of these vermin when my daughter was infested, and the […]

A better simulation of jet lag than that described in this article would have been to shift daytime forward 1 week, then back the next, and continue alternating for the 8 weeks of the experiment. This would mimic actual travel, rather than simulating endless trips around Earth in one direction. Dian Duchin ReedSoquel, Calif.

It is not only the scientific literature that documents the unexpected “doughnut” pattern in swarms. Italo Calvino’s fictional Mr. Palomar observed (rather more lyrically) about the flocking of Roman starlings, “Finally a form emerges from the confused flutter of wings, advances, condenses: it is a circular shape, like a sphere, a bubble, the balloon-speech of […]

Wasted youth The experiments with mice infected with the 1918 influenza virus are important but not surprising (“The Bad Fight: Immune systems harmed 1918 flu patients,” SN: 9/30/06, p. 211). John Barry’s The Great Influenza: The Epic Story of the Deadliest Plague in History (2004, Viking) explains that many, perhaps most, of the victims were […]

Concerning this article, I have yet to read a single study regarding the alleged benefits of circumcision that acknowledges that the foreskin is erogenous tissue. Removal of erogenous tissue from a female would be considered barbaric, even if it did offer some protection against sexually transmitted diseases. Jerry MalonePueblo, Colo. This is surgery, which should […]

It would seem difficult to distinguish between the repulsive force that dark energy proposes and the regular gravitational pull of ordinary matter. Somehow, the idea of multiple universes surrounding our universe, embodying the known laws of physics and providing the gravitational pull, is easier for me to accept than a mysterious dark energy nobody can […]
