In this article, I read that an orb of a given size, when slightly flattened, will pack more densely than when perfectly round. No kidding? Do you suppose if we were to crush cars into little cubes we could hurl more into a landfill than we could just by driving them over a cliff? What […]

Revealing words “Bookish Math: Statistical tests are unraveling knotty literary mysteries” (SN: 12/20&27/03, p. 392: Bookish Math) 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 […]

This article details an advance in human-cloning efforts. The researchers charging into this field think that we should pass laws to keep others from abusing their research. Ha! Do they really think they can keep this genie in a bottle? If this keeps up, it won’t be long before people are cloning themselves and maybe […]

Your article refers to a virus as a “microbe.” I think of a virus more as a seed or spore. What definition is Science News using for the word? Neil MurphyWalnut Creek, Calif. Medical dictionaries differ in defining viruses as microbes . Merriam-Webster’s Collegiate Dictionary Eleventh Edition ( 2003, Merriam-Webster ) says that viruses are […]

Warm topic I was fascinated by the article on heat production in flowers (“Warm-Blooded Plants?” SN: 12/13/03, p. 379: Warm-Blooded Plants?). It speculated on the evolutionary origins of such 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 […]

Regarding this article, did the researchers image the brains of disabled people who know the meaning of a verb but can’t perform the action, or of people without any disabilities who know the meaning of a verb such as “scull” but have never performed the action? It seems that without the above-mentioned types of tests, […]

The thought that anyone, Eskimo or otherwise, would willingly kill a member of an endangered species that may have been swimming when George Washington was still alive makes me sick at heart. Honoring one’s ancestors could surely be achieved by going out in a whaleboat, engaging in a mock hunt, and showing true reverence for […]

This article could leave the impression that the evolutionary significant unit (ESU) is the de facto concept employed for all listing decisions under the Endangered Species Act. In fact, the ESU has not been used in the vast majority of recent listing decisions under the act. Nor should it be. The act allows the National […]

Of course animals think, I’d say. But you say, “Many [scientists] theorized that nonhuman animals react to their surroundings without actually thinking.” My observation over the decades has been that most humans do the same, most of the time. George BlenderSan Diego, Calif. You don’t need all the elaborate experiments described in the article. If […]

The statement by Kyeongjae Cho that “we don’t have enough platinum” for a hydrogen economy based on fuel cells is simply wrong. Anyone who is working in the fuel cell industry expects the amount of platinum used in fuel cells to drop by the time this technology will be available for a mass market. If […]

In regards to the picture accompanying this article, it might be helpful to remind readers that such colorful depictions of nanoscale materials are slightly fanciful. These structures exist in realms so small that visible light, and therefore color, has little meaning. James HedbergPortland State UniversityPortland, Ore.

I’m confused. This article says that “atherosclerosis isn’t linked to oxidation of bad cholesterol.” If not, why does the article “Telltale Charts” (Telltale Charts) name cholesterol as one of the traditional risk factors? What is really going on with cholesterol? Sandor FrecskaLancaster, Pa. Good question. While epidemiological studies offer compelling evidence that blood-cholesterol concentrations influence […]
