Sleeper issues I have experienced sleep paralysis in almost all of its forms, from terrors to vibrations and auditory hallucinations to out-of-body experiences (“Night of the Crusher,” SN: 7/9/05, p. 27). Most often it is completely terrifying, but I did have one episode that was elating. Sweet dreams. Kathleen MilroyOntario, Canada The manifestations reported by […]

Just a little gas “Energy on Ice” (SN: 6/25/05, p. 410) states that the gas-hydrate deposit near Prudhoe Bay “contains more than 1.2 trillion cubic meters of gas. That’s twice the total amount of natural gas consumed annually in the United States. …” Does it behoove us to invest the time and dollars it will […]

I wonder if any of the researchers had a pet bird. My Alexandrine parakeet can smell beer or ice cream from two rooms away—She screams for her share. Bruce DowRidge Manor, Fla.

The plates on Stegosaurus and the fleshy, domed skulls on pachycephalosaurs could certainly have been for recognition, but not the kind of recognition cited in this article comparing it to teen fashion. Isn’t flashy recognition often a sign that says, “Don’t eat me because I am poisonous”? There may have been enough noxious secretions in […]

This article gives the impression that the increase in skin cancer among young people is caused by tanning in the sun. Environmental factors such as ozone depletion should have at least been referenced in the article. Cathy Hodge McCoidSacramento, Calif. In your article, the conclusion that young people are getting more skin cancers because “people […]

Bay listen It was interesting to read of processing mundane noise to produce an ultrasound image of the geology of Los Angeles (“Seismic noise can yield maps of Earth’s crust,” SN: 6/11/05, p. 382). A big question in the state is the deep structure of San Francisco Bay. Clearly, the bay and the valleys extending […]

This article says that fungal sprays could kill nontarget insect species, “but most of those species people don’t want anyway.” That is a flippant way to blow off reasonable questions. “Most” means “not all,” so some of them people would want. And I would suggest that most people don’t want (don’t care about) worms or […]

While no obstetrician nowadays advocates starving expectant mothers, there was a general belief for many years that a pregnant woman should gain minimal weight. It might be of interest to know if this practice had any influence on the incidence of schizophrenia. Nelson MaransSilver Spring, Md.

Empty threat? “Empty Nets: Fisheries may be crippling themselves by targeting the big ones” (SN: 6/4/05, p. 360) reads as if there is something to be alarmed about. By selectively catching large fish, we have reduced “the mean size [of food fish to] one-fifth of what it was.” This is not cause for alarm. It […]

This article reports on research indicating that winds above the ocean surface can increase due to an apparent damping of turbulence by particles of ocean spray. I would like to point out that a similar phenomenon has been identified in rivers. In situations where the transport of fine sediment particles (sands, clays) coming from the […]

Your article was very interesting, but it didn’t mention the possibility of a genetic bottleneck after Homo sapiens was already dispersed into Asia and then eliminated from everywhere but Africa by the Toba volcano in Sumatra 74,000 years ago. It has been said that during the colder times after the explosion, the cold-adapted Homo neanderthalensis […]

Does the name of Honda’s robot, Asimo, have a meaning in Japanese, or is it just a tip of the hat to Isaac Asimov? Dennis LynchGlenshaw, Pa. Asimo’s name stands for Advanced Step in Innovative Mobility.—N. Moreira
