In the article "Reexamination of acoustic evidence in the Kennedy assassination" by the Committee on Ballistic Acoustics, National Research Council (8 Oct., p. 127), the probability given on page 130, column 1, line 17, was incorrectly printed. It should have been "P = .044."     

Corrections and clarifications

In the Research News article "Pot, heroin unlock new areas for neuroscience" by Marcia Barinaga (18 Dec., p. 1882), the diagram of the molecule anandamide on page 1883 was incorrect. The correct structure appears on page 1948 of the same issue, in figure 1A of the report "Isolation and structure of a brain constituent that binds to the cannabinoid receptor" by W. A. Devane et al. (p. 1946).     

Erratum

In R. Jeffrey Smith's News and Comment article "Antisatellite weapon sets dangerous course" (14 Oct., p. 140), a remark on page 141 (column 3) by Richard Garwin about the usefulness of rockets, balloons, and aircraft to supplant U.S. photoreconnaissance and meterological satellites was inadvertently attributed to Robert Buchheim. And a characterization on page 141 (column 2) of the Soviet antisatellite weapon, or ASAT, was actually made by General Lewis Allen, the former Air Force chief of staff, not by General David Jones, the former chairman of the Joint Chiefs of Staff. Finally, a footnote on page 142 should have identified the Patriot as an air-to-air missile, not an air-to-ground missile.

In the issue of 29 Oct. 1954 the name of the third author of "Effect of 2,4-D on respiration and on destruction of IAA in oat and sunflower tissues," page 710, was incorrectly spelled. It should be Dawson C. Deese (not Desse).     

Errata for Volume 123

In the article "Pronuclear fusion as affected by x-rays and by postirradiation anaerobiosis," by C. S. Bachofer, in the issue of 27 Jan., page 139, the last sentence in column 1 should begin "The term (1/4)-fused is used to designate ...," not "The sum (1/4)-fused . . ." as printed. In the article "Magnetic techniques for in vitro isolation of leucocytes," by Sumner Levine, in the issue of 3 Feb., page 186, the equation should read micro radicaln(n+2)=4.90 Bohr magnetons, instead of as printed with the square root sign covering the last part of the equation.     

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."

Erratum

The caption for a series of head scans shown in the News & Comment article "AZT reverses AIDS dementia in children" (6 Oct., p. 21) was in error. The pictures of the brain, obtained by a CAT scan, indicate brain physiology but not metabolism. The latter would be revealed by a PET scan.     

Erratum

In the report "A plant leucine zipper protein that recognizes an abscisic acid element" by M. J. Guiltinan et al. (12 Oct., p. 267), figure 2 (p. 269) was incorrectly printed. The legend was correct. The correct figure appears below.
