Paragraph In Column Research Articles

Correction

In Bernard D. Davis' article "Bacterial domestication: Underlying assumptions" (Policy Forum, 13 Mar., p. 1329), the word "no" was erroneously omitted from the last sentence of the first full paragraph in column two on page 1334. The sentence should have read, "But this view builds on a parallel between genetic engineering and the physical technologies, rather than on a much closer model, with very different predictions: the domestication of wild organisms, resulting in enormous benefits and no catastrophes."

Erratum: Use of and Research on Pheromones

In the article "String as a theory of everything" by M. Mitchell Waldrop (Research News, 20 Sept., p. 1251), the last line of the first column was inadvertantly omitted. The affected sentence should have read, "Not only were the strong interactions far more complex than predicted by field theory, but the particles that participated in the strong interactions-the hadrons, a group that includes protons, neutrons, pi mesons, and many others-seemed to be relatively large, extended objects as much as 1 Fermi across (10(-13) centimeter)." In the next-to-the-last line of the second full paragraph in column 2 on page 1252, 10(-19) should have been 10(+19). Finally, the words "quandary" (page 1251, column 1, paragraph 6, line 2) and "quark" (page 1252, column 3, last paragraph, line 18) were misspelled.

Radioenzymatic Assay for Direct Measurement of Plasma Pyridoxal 5'-Phosphate

Abstract Vol. 29 p 642: In column two, sixth line from the bottom, change "25 000" to "54 000." Insert an addition (italicized here) to the next to last line in that column so that it reads".. ., then dialyzed overnight against the same buffer at 4 °C, then divided..." p 843: In line six under Results and Discussion, change "mg" to "µg" p 1537: In revision of this paper a paragraph of introduction was inadvertently omitted (which cites refs. 1-5), as were the first two paragraphs under Materials and Methods, which should read as follows: Human placentas were obtained from the obstetrical department within 12 h of delivery. Fresh human abdominal muscle was obtained within 12 h of autopsy. All tissues were stored at 4 °C and processed, as described below, within 6 h. Placenta and abdominal muscle were stripped free of membranes and blood vessels, cut into small pieces, and extensively washed at 4 °C with cold saline (NaCl, 9 g/L). Muscle CK-MM and placental CK-BB were purified according to the method of Armstrong et al. (6), with the following modifications: we used dithioerythritol (Sigma Chemical Co., St. Louis, MO 63178), 15 mmol/L, instead of 2-mercaptoethanol, omitted the final (NH4)2SO4 precipitation and final Sephadex G-100 fractionation, and used DE-52 (Whatman Ltd., Maidstone, Kent, U.K.) instead of DEAE-cellulose (Cellex-D; Bio-Rad Laboratories, Richmond, CA 94804). p 2026: First paragraph, lines nine and 16: delete "500" (the Dextran used in the cited reference was a 50 000-dalton preparation, not the 500 000-Da Pharmacia preparation). p 2029: In line 10 of the first full paragraph in column two, change "1.171" to "0.117." p 2125: First two columns and Table 1: All lipase results expressed as kU/L should be divided by 3600. Vol. 30 p 170: The next-to-last paragraph was inadvertently omitted in layout and should read as follows: If the sample was first incubated at 37 °C until the serum became clear (i.e., until the cryoprecipitate dissolved) and the enzyme activity immediately determined at 30 °C (Figure 2, curves 1 and 2), normal activity was observed.

Erratum: Association of Parvoviruses with Rheumatoid Arthritis of Humans

On page 1426 of the report "Association of parvoviruses with rheumatoid arthritis of humans" by R. W. Simpson et al. (30 Mar., p. 1425), a portion of the text beginning on line 18 of the first full paragraph in column 3 was incorrectly printed. It should have read, "We were unable to detect 24-nm particles in brains of normal mice from our colony or mice intracerebrally inoculated with extracts of synovial cells from patients with noninflammatory degenerative joint disease (DJD). More conclusive evidence for the identity of RA-1 as a parvovirus comes from our recent success in demonstrating that CsCl gradient fractions containing the infectious 24-nm particles can be extracted for a single-stranded DNA which is approximately 4.5 kilobases in size."

On p. 66 of the Feb. 21, 1984 issue of Eos, the paragraph in column 2 under Other Awards headed "Robert E. Horton Medal" should have appeared at the bottom of column 1, just before the section headed "Robert E. Horton Research Grant."

Erratum: New Test of Variable Gravitational Constant

In the Research News article "New test of variable gravitational constant" (23 Dec., p. 1316), in the third paragraph of column two on page 1317, a minus sign was left out of an exponent. The correct value for the drift of atomic clocks relative to gravitational clocks is (0.1 ± 0.8) × 10 -11 per year.

No. 37 255). pp 60-62: The last terms of the equations in abstract and text should read "0.0138" instead of "1.380," and "0.0037" instead of "0.37." In Table 2, move the decimal two places to the left for all values under b (columns 3 and 5).

Hang Gliding

In the SPECIAL COMMUNICATION, "Injuries Associated With Hang Gliding," published inthe July 14 issue (233:158-160, 1975), an error occurred. On page 159, in the last line of the first column, the alcohol concentration found in the flyer's blood was<b>50</b>mg/100 ml, not 0.05 mg/100 ml. Also in the EDITORIAL titled "Hang Gliding," published in the same issue, the control mechanism of the hang glider was described incorrectly on page 171. The first sentence of the fourth paragraph in column 1 should read: "Control during flight is gained with a control bar that, when pushed forward,<b>raises</b>the nose of the kite or glider, causing the glider to accelerate."
