Readers on reading Other librarians and I regularly discuss illiterate, functional, aliterate, and avid readers. I am pleased that research has begun into what happens in readers’ brains (“Words in the Brain: Reading program spurs neural rewrite in kids,” SN: 5/8/04, p. 291: Words in the Brain: Reading program spurs neural rewrite in kids). The […]

Not to detract from this project’s accomplishments or its potential, but does space really need tourists? It’s not a sideshow. It will still be dangerous and expensive. Assuming that space travel will be like today’s airline travel is mistaken, especially in the near term. Let’s remember that this project’s success so far also rests on […]

This article didn’t mention that professional journals usually charge exorbitant page charges, require that a paper be sent in a format that can be directly typeset, and price print and electronic subscriptions identically. What I conclude from this is that greed is as prevalent at professional societies as it is in the commercial world. Edmond […]

While heart disease victim Jody Gorran’s lawsuit against the Atkins empire will be decided in court, the deadlier battle is being waged in the research laboratory. Several studies confirm that low-carbohydrate diets cause marked cholesterol elevations for many individuals. In contrast, a vegetarian diet high in soluble fiber and soy protein can lower serum cholesterol […]

In the close-up from the Cassini spacecraft, some of Saturn’s rings look rather like grooves in a phonograph record. I wonder if anyone has tried mapping those grooves to see if they can be played using the method described in “Groovy Pictures: Extracting sound from images of old audio recordings” (SN: 5/29/04, p. 339: Groovy […]

The counterintuitive finding that atrazine is more likely to kill tadpoles when it is highly diluted reminds me of a similar phenomenon in the alternative health care practice of homeopathy. Tracy SellersRowlett, Texas

The teardrop shape of Venus away from the centermost part of the sun simply is caused by the photographic surface being planar, rather than spherical. The image can never be represented without distortion for the same reason that the globe can’t be represented without distortion on a flat map. Robert P. Kelso San Marcos, Texas […]

Language of music The study by Hyde and Peretz about people inept at all things musical (“Brain roots of music depreciation,” SN: 5/8/04, p. 302: Brain roots of music depreciation) made me think of my spouse of 20 years. In addition to a lifetime of utter tone deafness, he also nearly didn’t receive his graduate […]

I don’t think anyone should be surprised that squirrels have figured out how to say “nyah, nyah” to rattlesnakes. After all, it’s what they’ve been saying to cats, dogs, and bird-feeder owning humans for years. R. Kelly WagnerAustin, Texas

Whale, of an annoyance In “Din among the Orcas: Are whale watchers making too much noise?” (SN: 5/1/04, p. 275: Din among the Orcas: Are whale watchers making too much noise?), Rus Hoelzel states, “One thing I want to make clear is that I think whale watching is a good thing.” He then states that […]
