Corrections

In the Research News article "New theory of hormones proposed" (12 Mar., p. 1383) by Gina Kolata, glycyrrhetinic acid and tetrahydrocannabinol were incorrectly identified as alkaloids. This misidentification in no way changes the conclusions about these plant substances.     

Corrections

In "Women in Science: Some Books of the Year" (11 March, p. 1458) the name of the senior editor of second edition of The History of Women and Science, Health, and Technology should have been given as Phyllis Holman Weisbard, and the name of the editor of the first edition should have been given as Susan Searing. Also, the statement that the author of A Matter of Choices: Memoirs of a Female Physicist, Fay Ajzenberg-Selove, is now retired was incorrect.     

Corrections and clarifications

The price listed for Franco Pavese and Gianfranco Molinar's Modern Gas-Based Temperature and Pressure Measurements (Plenum Press) in the Books Received column of 6 November (p. 1015) was incorrect. The price of the book is $110.     

Corrections and clarifications

The Books Received listing of 26 November (p. 1463) for Thomas F. Lee's Gene Future: The Promise and Perils of the New Biology (Plenum, New York, 1993) included a line of information that did not apply to that book. The price given for the book, $24.95, was correct.     

Corrections and clarifications

In the report "A nuclear-encoded form II RuBisCO in dinoflagellates" by D. Morse et al. (16 June, p. 1622), in the seventh line of the first full paragraph in the third column on page 1622, "glysine-cysteine" should have been "guanine-cytosine."     

Corrections and clarifications

In This Week in Science, 10 March, page 1401, under the title "Knowing when to go," the name of the nematode Caenorhabditis elegans was misspelled.     

Corrections and clarifications

In the Research News article "Extreme ultraviolet satellites open new view of the sky" by Donald Goldsmith (14 Apr., p. 202), astronomer Stuart Bowyer was incorrectly identified as the director of the University of California, Berkeley's Center for Extreme Ultraviolet Astronomy. Bowyer was the founding director of the center and was succeeded by Roger Malina, who became acting director in 1994 and is now director. Malina is, with Bowyer, a principal investigator of the National Aeronautics and Space Administration's EUVE (Extreme Ultraviolet Explorer) mission.     

Corrections and clarifications

In the report "Activation and regeneration of rhodopsin in the insect visual cycle" by A. Kiselev and S. Subramaniam (25 Nov., p. 1369), the second and third sentences of the last paragraph on page 1371 were incorrectly printed. They should have read, "When rhodopsin was re-excited immediately after it was regenerated, most of the metarhodopsin formed was thermally stable (that is, M(b) was formed predominantly; Fig. 4A). However, when rhodopsin was re-examined after waiting for various lengths of time (in the dark), an exponential increase was observed in the amount of thermally unstable metarhodopsin produced, implying heterogeneity in the rhodopsin population."     

Corrections and clarifications

The photograph on page 1415 accompanying the book review of Luna B. Leopold's A View of the River by Vic Baker (25 Nov., p. 1414) showed meanders of the East Fork River near Boulder, Wyoming, not the Popo Agie River.     

Corrections and clarifications

In the news briefing "The world's most prolific scientists" (17 Jan., p. 283), Arnold L. Rheingold, a crystallographer at the University of Delaware, was inadvertently left off the list of the top 20 most prolific scientists. The Institute for Scientific Information has corrected its list and states that Rheingold published 391 articles and other scientific communications between 1981 and the end of 1990. He should have ranked 13th on the list.     

Corrections and clarifications

The caption accompanying the News article by Steve Sternberg "The emerging fungal threat" (9 Dec., p. 1632) should not have included the words "in the body." Candida albicans produces hyphae, but not chlamydospores, in the body.     

Corrections and clarifications

The Research News article by Faye Flam about the 1993 physics Nobel Prize ("A prize for patient listening," 22 Oct., p. 507), awarded to Joseph Taylor and Russell Hulse for the discovery of a binary pulsar, incorrectly attributed key observations. The measurements implying that the pulsar is emitting gravitational waves were made by Taylor in collaboration with Joel Weisberg, Lee Fowler, and Peter McCulloch, not by Taylor and Hulse.     

Corrections and clarifications

In the letter of 23 October by Charles A. Gardner (p. 530), Dr. Gardner's address was incorrectly given as the Subcommittee on Human Resources and Intergovernmental Relations of the House Committee on Government Operations. Dr. Gardner was a AAAS Congressional Science Fellow assigned to that subcommittee through August 1992, but the views expressed in his letter were his own and not those of the subcommittee.     

Corrections and clarifications

In note 6 (p. 54), of the Policy Forum "The paradox of critical mass for women in science" by H. Etzkowitz et al. (7 Oct., p. 51), the author of Fair Science: Women in the Scientific Community should have read, "J. Cole."     

Corrections and clarifications

Figure 1, parts A and C (p. 1349), of the Research Article "Calcium-calmodulin modula- tion of the olfactory cyclic nucleotide-gated cation channel" by Mingyao Liu et al. (25 Nov., p. 1348) were incorrectly printed. The correct figures appear below. On page 1351 of the same article, in line 25 of the first column of text, "GMP" should have been "AMP." In the second line of the text on page 1352, the first "(C.Ln)o" should have been "(C.Ln)c."     

Corrections and clarifications

The names of Charles Kennel and Thomas A. Tombrello, Jr., were mispelled in John Travis' 30 April News & Comment article "LIGO: A $250 million gamble" (p. 612).

In the response by E. A. Finch and S. M. Goldin (5 Aug., p. 813) to the technical comment "Calcium and inositol 1,4,5-trisphosphate-induced Ca(2+) release" by L. Combettes and P. Champeil (5 Aug., p. 813), in parts B and C of figure 1 (p. 814), the insets referring to Ca concentrations were inadvertantly interchanged. The concentration for figure 1B should have been, "300 nM Ca" and that for figure 1C should have been, "10 nM Ca."     

Corrections and clarifications

In the report "Single molecules observed by near-field scanning optical microscopy" by E. Betzig and R. J. Chichester (26 Nov., p. 1422), figure 2 on page 1423 was incorrectly printed. The arrow representing the molecular dipole p was missing in the top part of the figure. The correct figure appears below. [See figure in the PDF file].     

Corrections and clarifications

In the article "Molecular basis of mammalian sexual determination: Activation of Müllerian inhibiting substance gene expression by SRY" by C. M. Haqq et al. (2 Dec., p. 1494), parts B and C of figure 1 were inadvertently interchanged. In figure 3A, the third, fourth, and fifth lanes should have been labeled "A(7) --> T," "A(7) -->C," and "A(7) --> G," respectively. In figure 5, the factor labeled "SRIF's" should have been labeled "SRYIF's."     

Corrections and clarifications

Figure 2 on page 523 of the Report "Magnetoferritin: In vitro synthesis of a novel magnetic protein" by F. C. Meldrum et al. (24 July, p. 522) was incorrect. The correct figure is printed below. [See figure in the PDF file].
