Horvath and Toffel’s comparison of the environmental impacts of the paper versus the electronic editions of the New York Times is a bit misleading. A personal digital assistant isn’t good for advertising or newspaper browsing. In other words, the PDA users aren’t getting a comparable product. Still, the day is probably not too far off […]

Go with the flow In “Tales of the Undammed: Removing barriers doesn’t automatically restore river health” (SN: 4/10/04, p. 235: Tales of the Undammed), the photo comparison of the dam site is deceptive because the two photos of the same spot appear to have been taken during different seasons. Hence, the lower photo shows a […]

In the article, an agronomist claims that farmers “typically apply more fertilizer than their crops need” as an explanation for increased pollution in coastal waters. I don’t know any farmers who risk their products in the way suggested here. An examination of home lawn care would point to a much bigger problem. Mary HeinrichtCulpepper, Va. […]

Evidently, death waits for no one, except in Belgium. Around 40 years ago, Belgian doctors went on strike for 3 months. If I remember correctly, their explanation for the fact that the death rate dropped during this period was that their patients hung on until the doctors were back at work!

The article on nanotubes as light sources was frustratingly sketchy. Any photometric laboratory with a wattmeter could compare the nanotube unit to another light source in a few minutes. It is tempting to think that the heating effect, which must be close to that from a blackbody radiator, and the “electronic effect,” which is undoubtedly […]

When cyanobacteria and plants transfer electrons photosynthetically, light is absorbed not by their photosynthetic proteins but by chlorophylls. Some of these proteins indeed participate in electron flow, but they are not plant photoreceptors. How then, do they “retain their function” and “absorb photons” in the fabricated solar cell described? Cleon RossVictor, Idaho The materials that […]

Blackened reputation Again, humans are implicated in the promotion and distribution of our own misery (“Medieval cure-all may actually have spread disease,” SN: 4/3/04, p. 222: Medieval cure-all may actually have spread disease). However, if bitumen was wrongly credited with darkening the skin of mummified remains, what caused it? Robert FizekNewton, Mass. The coating on […]

Since the hypoxia described in this article isn’t caused directly by the fertilizer, but by the subsequent algae blooms, then perhaps an effective solution is to combat the algae. It might even be profitable to harvest the algae. If the fishing industry is capable of depleting the seas of species that we want there, then […]

The Japanese researchers who dubbed a pachyderm secretion to be “hipposudoric acid” seem to know more about biochemistry than about etymology. The word hippopotamus is a synthesis of Latin hippo (horse) and potamus (river), apparently because of the resemblance of the face of a submerged hippopotamus to the head of a horse. Hipposudoric implies a […]

This article seems to use “aspirin” and “acetaminophen” interchangeably. Aspirin is acetyl salicylic acid, not acetaminophen (better known as Tylenol). Tom WarmMustang, Okla.

I don’t want to downplay genuine discovery, but your story about optically reading old records left me a little underwhelmed. The optical playing of records has been available in the commercial market for several years. Just do an Internet search for “laser turntables.” Jerry BoehmSchenectady, N.Y. This is not an especially new invention. A commercial […]

Judging by science “Forensics on Trial” (SN: 3/27/04, p. 202: Forensics on Trial) was an eye-opener. Our courts may be accepting many analytical techniques that haven’t been adequately validated. We should be careful, especially where the death penalty is involved, not to be guilty of hubris in the application of scientific knowledge. Bob SauerPrinceton, Mass. […]
