Fishy Conversations — Spiny lobsters are like men, their voices become deeper as they grow older. This is one of the preliminary findings of Dr. James M. Moulton of Bowdoin College, Brunswick, Me., who spent this summer at the Bermuda Biological Station eavesdropping on the conversations of undersea life. In countless other marine biological stations and research laboratories throughout the world, other researchers like Dr. Moulton are studying the various aspects of the oceans. The aim is twofold: They hope to unravel some of the mysteries of what many scientists feel is the “last frontie...Published: Friday, September 26th, 2008

Only in the north It is not clear in the fine article on volcanoes (“Disaster goes global,” SN: 8/30/08, p. 16) how dust from the eruption of Huaynaputina, well south of the equator, in 1600 could affect only the Northern Hemisphere. David Bronson, Biddeford Pool, Maine For one thing, there’s less real estate in the Southern Hemisphere to have been affected. Also, the apparent lack of agricultural effects probably stems from population distribution at the time this eruption popped off. Australia was inhabited only by Aborigines until 1787 or so, and Cape Town, South Africa, wasn’t...Published: Friday, September 26th, 2008

PARKINSON’S DISEASE NO LONGER INCURABLE — Parkinsonism, or shaking palsy, is no longer a hopeless, progressive, incurable disease. A five-year follow-up study of 700 brain operations for Parkinsonism revealed that 80% of the properly selected cases found relief from the tremor, rigidity, deformity and incapacitation of parkinsonism after basal ganglia surgery. Furthermore, these symptoms can be relieved by operation without fear of any psychological or neurological damage to the patient, Drs. Irving S. Cooper and Gonzalo J. Bravo of the department of surgery, New York University-Bellevue M...Published: Friday, September 12th, 2008

A climate tipping point In Janet Raloff’s article “Forest invades tundra” (SN: 7/5/08, p. 26), there seems to be a paradox. Raloff says that the albedo from normal snow coverage of the tundra “helps maintain the region’s chilly temperatures,” implying that the coverage also preserves the mats of plant matter. A little later in the article, Ken Tape explains how the arrival of tiny shrubs traps snow, insulating and warming the soil beneath and stimulating the growth of bacteria. At what point does snow’s effect change from a chilling blanket that preserves the tundra ecology to...Published: Friday, September 12th, 2008

RNA INFLUENCES CELL DIFFERENTIATION — Ribonucleic acid has been pinpointed as having an essential role in cell differentiation, the process by which the early embryo’s look-alike cells become nerve, bone, skin and other organs. Working with extremely small quantities of cellular material, 20 to 50 cells, taken from embryonic newt and salamander tissue, Dr. M. C. Niu of the Rockefeller Institute for Medical Research, New York, found that the presence of ribonucleic acid is critical for the formation of specialized tissues. He used cells removed from two-to-five-day-old fertilized egg...Published: Friday, August 29th, 2008

Disturbing numbers I found the “Sizing up science” Science Stat (SN: 8/2/08, p. 4) somewhat disconcerting with regard to the opinion about medicine. Basic medical research, in which ties to pharmaceutical companies and the like are not limited, may be “scientific” in the usual sense, but once you enter the arena of clinical research, the “scientific” is scarcely applicable. Objectivity and truth in reporting are not exactly encouraged in the current clinical medical research climate. It should be unsettling that a paper reporting an important negative result — one that ne...Published: Friday, August 29th, 2008

NO “SAFE” RADIATION DOSE — There is no period of safety after exposure to harmful radiation, a geneticist reports. Radiation has been found to affect the primitive germ cell from which the sperm develops. Chromosome abnormalities may be transmitted to offspring in dangerous numbers for a long time after irradiation of the male. This also is important evidence that there is no such thing as a “minimum permissible dose of radiation,” says Dr. A.B. Griffen of the Roscoe B. Jackson Memorial Laboratory, Bar Harbor, Me. Until now many scientists had believed the effects of irradiation on t...Published: Thursday, August 28th, 2008

Home / SN Bookshelf / Reframing Scopes: Journalists, Scientists, and Lost Photographs from the Trial of the CenturyWatson Davis clipped a short article out of a newspaper on May 7, 1925. John Scopes had been arrested for discussing evolution in a Tennessee public high school. In the Scopes trial, Davis saw an opportunity for his young nonprofit organization, Science Service, to prove its worth. The Science Service Executive Committee agreed to give its reporters $1,000 to cover the trial. The committee also decided to reject neutrality, supporting the defense on the side of evolution. Davis and Frank Thone, the senior biology editor of Science Service’s newsletters, acted as journalist...Published: Monday, August 4th, 2008
