  1. The earliest Left handed DNA that we are aware of is an Israeli stamp from 1964. The image was sent to me by Irwin Tessman (Department of Biological Sciences Purdue University West Lafayette IN 47907-1392). The stamp is in "Chemistry on stamps (chemophilately)". Rappoport, Z. Acc. Chem. Res., 25(1), 24- 31, 1992. It is in the lower right corner of Figure 2, and is described on page 30 as having 'the "abnormal" helicity of DNA'. Click to see the complete beautiful stamp.
    as of 1998 Nov 23
    1978
  2. The now out of print book, Molecular Biology of the Gene by James D. Watson (W. A. Benjamin, Inc, Menlo Park, California, third Edition, ISBN 0-8053-9609-8) has a series of left handed DNA pictures on pages 228 (fig 9-18), 263 (fig 10-10 and 10-11), 268 (fig 10-16), 290 (fig 11-8), 292 (fig 11-9), and 419 (fig 15-9). (Thanks to Richard Wolf (wolf@umbc.edu) for pointing this one out!) as of 1999 April 23. "There is at least one additional drawing of left-handed DNA on p. 216 (fig 9-9). Also, the Fig. 11-8 on p. 290 is particularly cute in presenting a right-handed structure amidst two left-handed flanks in the same drawing (the central portion showing a hybrid duplex of RNA/DNA, though)." (Thanks to Richard Egel, richard.egel@molbio.ku.dk for pointing this one out!) as of 2000 August 18.
    around 1980
  3. Until Dr. Tessman informed me otherwise in November 1998, the earliest example I was aware of is a beautiful drawing of a circular plasmid by the Beckman Company published around 1980. "Our experience covers over 40 years of innovation and unmatched quality".
  4. On the cover of Nature Volume 284 Number 5757, 17 April 1980 is on left handed "Selfish DNA" (a series of left-handed twisting snakes eating each other in a circle). The person who found it writes:

    Hi there! Yes, I am a Newsweek reader. I am also an artist responsible for perhaps one of the first left-handed boo-boos.

    My husband and his old advisor (Doolittle and Sapienza) wrote a piece on "Selfish DNA" that was accepted by Nature. Their paper and another by Crick and Orgel became the magazine's cover topic. Lucky me! I got to draw for Nature!

    No one noticed that my design was left-handed until the journal was in press. I will admit that the scientists thought it was pretty funny (well, what could they do at that point?).

    In the US the background color was an ugly light orange, but the British version was a vivid red.

    I'm starting to feel like a real part of history here...uh, infamous too.

    ...

    Thanks for a great site!

    (Thanks to Linda Angeloff Sapienza, LASplumas@aol.com, for pointing this one out!)

    1982
  5. Principles of Biochemistry by Albert L. Lehninger, Worth Publishers, Inc., New York. ISBN 0-87901-136-X. (added 1998 April 8) Page 850 shows a relaxed left handed DNA circle which when acted on by DNA gyrase with the hydrolysis of ATP to ADP + Pi becomes a supertwisted right-handed DNA.
    1983
  6. The Cartoon Guide To Genetics by Larry Gonick and Mark Wheelis (Barnes & Noble, NY, 1983), is a wonderful and funny introduction but unfortunately the cute RNA polymerase on the cover is chewing away at a left handed DNA. The cover of the updated edition has the even odder DNA that is changing twist as the RNA polymerase moves by. (It's a great book anyway!!)
  7. In a letter Nature 305:176 (1983) John H. Wilson and Peter B. Berget point out that in the advertisement for the Symposium: Molecular Biology Now & Tomorrow was a DNA that was simultaneously left and right handed! (Thanks to John Wilson for pointing this one out.)
    1989
  8. Arthur Kornberg, discoverer of DNA polymerase, wrote a book:
    For the love of enzymes: the odyssey of a biochemist Cambridge, Mass., Harvard University Press, 1989.
    In the section on "Astonishing Machines of Replication" on page 227, figure 7-14 there is a figleaf covering the point of DNA replication, all of the strands coming out of it are left handed.
  9. An Amgen advertisement in Nature 340, 17 August 1989, shows a replicating left-handed DNA in space over the North American continent, with the words "Amgen Biologicals: bringing world class products to the forefront of biomedical research". Space invaders?
  10. The Trends in Biotechnology cover January 1989, Volume 7 No.1 shows both left and right-hand forms coming from a single plant.
    1995

    1990
  11. The Trends in Biotechnology cover June 1990, Volume 8 No.6 shows an SEM image of a left-handed DNA with the words "Scanning Tunnelling Microscopy of Biomolecules". In the article itself ("Scanning tunnelling Microscopy in Biotechnology", P. G. Arscott and V. A. Bloomfield, page 153), fig 2 shows a left-handed DNA with a figure legend stating that it is "in the left-handed Z form". Yet on page iii is "Front Cover ... A single molecule of B-form DNA ..."
  12. The IBI 1990 Catalog cover two kinds of model, both left handed.
  13. Perkin Elmer Spring 1990 Biotechnology Catalog cover
  14. Bio-Rad Bio-Radiations No. 76, 1990, page 4, "DNA Preparation for Forensic Analysis" with a left-handed helix. To track the space invaders? "Image: Nelson L. Max".
  15. A Genosys advertisement in Trends in Biochemical Research 15(4) April 1990. "Some good things you have to wait for." (under a picture of wine and glasses) "Others you don't." (under a picture of left-handed DNA).
  16. "Logic of the Escherichia coli cell cycle", Richard D'Ari and Philippe Bouloc, cartoon in TIBS May 1990 15(5) 191-194.
  17. Clontech advertisement in Nucleic Acids Research 18(4) July 25, 1990. "we can offer you guaranteed quality and excellent service."
  18. Applied Biosystems meeting "Automating Molecular Biology: Tools and Techniques for the 90's", September 12, 1990, National Institutes of Health, Lipsett Amphitheatre, Bethesda, MD. This company makes the most popular DNA sequencing machine.
  19. Science 1990 Nov 9 issue had business reply cards to join membership in the American Association for the Advancement of Science. The card has the words: ' "I have to read SCIENCE every week" James D. Watson Nobel Laureate' above a left-handed DNA. This appeared in Science in two other formats, one on 1991 Aug 19. The original paper on the structure of DNA is: 
    @article{WatsonCrick1953,
author = "J. D. Watson
 and F. H. C. Crick",
title = "Molecular Structure of Nucleic Acids:
A Structure for Deoxyribose Nucleic Acid",
journal = "Nature",
volume = "171",
pages = "737-738",
year = "1953"}
  20. Biochemistry book by C. K. Mathews and K. E. van Holde, The Benjamin / Cummings Publishing Company, Inc. Redwood City, California, ISBN 0-8053-5015-2, 1990. Page 923 shows RNA polymerases working on left handed DNA that somehow manages to switch over to right handed DNA elsewhere on a circular plasmid. This is a pretty clear example of an artist flipping a drawing over. This textbook drawing was meant to show how transcription can cause supercoiling. It shows two polymerases transcribing towards each other, but with opposite DNA twists. A student could become rather confused: the DNA as drawn would not become supercoiled by the transcription!

  28. In a Letter to Nature volume 350, 21 March 1991, page 184, Irwin Tessman (Department of Biological Sciences Purdue University West Lafayette IN 47907-1392) wrote about the ``Sinister change'' that had already by that time come about. He listed 6 advertisements in Nature 1 5 and Science, 2 3 4 6 a book and a Biotechnology center. Dr. Tessman is the earliest identified DNA Leftologist (people like myself who are puzzled and worried by this growing effect).

  113. The New York Times Science Times section, Tuesday, October 21, 1997 page B9 shows two DNA helices, one associated with nucleosome "spools" and the other associated with a baby sucking a pacifier and holding a teddy bear. But is the baby human? (Thanks to William R Mcclure for pointing this one out.)
  114. BioTechnica advertisement in Science Vol 276, 19 September 1997, page 1852-3. "From Science to Buisness". CT technology advances: no longer just science, it is now involved in world business.

  118. W. Yang and K. Mizuuchi, Site-specific recombination in plane view, Structure, 5: 1401-1406, 1997. Figure 1 on page 1402 shows the strand breakage and reunion in site-specific recombination in the Lambda Int family. At the moment of rejoining the DNA strands all switch from right handed to left handed symmetry. The topological consequences of this switch have not been carefully considered.
  119. R. V. Miller, Bacterial Gene Swapping in Nature, Scientific American 278: 66-71 (January 1998). pages 69 shows transformation of a bacterium by left handed DNA.
  120. Library of Science (A Newbridge Book Club) Advertisement flyer for molecular biology books, 1997 December 31, shows a spectacular right handed DNA switching midstream into a left handed one, and a large left handed one in between the "bible for molecular biologists" and "[almost] an entire library of contemporary molecular biology [squeezed] into one volume".
  121. Elsevier Science web page gif noticed on 1997 December 31 at Gene-Combis
    It's pretty easy to see, but making it bigger makes clear that the left handed twist runs through the entire image:
  122. Elsevier Science web page gif noticed on 1997 December 31 at Gene-Combis Features. You don't believe me? I couldn't believe there was a second one either. Here it is enlarged:
  123. Elsevier Science web page gif noticed on 1997 December 31 at GeneCombis for the journal Gene (They did this on the cover of the journal in 1996, item #41.)
    Again, we need to enlarge the left hand part to see the left handed twist:

    The New Creationism: Biology Under Attack
    By Barbara Ehrenreich and Janet McIntosh
    When social psychologist Phoebe Ellsworth took the podium at a recent interdisciplinary seminar on emotions, she was already feeling rattled. Colleagues who'd presented earlier had warned her that the crowd was tough and had little patience for the reduction of human experience to numbers or bold generalizations about emotions across cultures. Ellsworth had a plan: She would pre-empt criticism by playing the critic, offering a social history of psychological approaches to the topic. But no sooner had the word "experiment" passed her lips than the hands shot up. Audience members pointed out that the experimental method is the brainchild of white Victorian males. Ellsworth agreed that white Victorian males had done their share of damage in the world but noted that, nonetheless, their efforts had led to the discovery of DNA. This short-lived dialogue between paradigms ground to a halt with the retort: "You believe in DNA?" http://www.thenation.com:80/issue/970609/0609ehre.htm

  149. DNASTAR advertisement in Science volume 281, 17 July 1998, page 308. The picture depicts the discovery of left handed DNA life forms in the sea. Some of the life forms are also right handed but the left to right ratio is 5 to 2, so *ulp* it looks like they are taking over!
  150. The Genesis Code by John F. Case. The cover of this 1997 book has a left handed DNA, and the San Francisco Examiner determined that this is "A SPELLBINDING BIOMEDICAL THRILLER . . . TERRIFYING." *ULP* I'd better read it to find out more about the situation!

  151. Genetic Maps and Human Imaginations: The Limits of Science in Understanding Who We Are by Barbara Katz Rothman. The book apparently deals with the ethical issues of sequencing humans who have left handed DNA.

  152. The Gene Letter As of August 1998, "Its main focus is on the ethical, legal and social issues that arise out of genetic advances" for both right and left handed DNA people. (They refused to allow me to show their masthead because they thought people would confuse this web site with theirs and because they think that their artist would not agree.) 1999 Jan 12: Dr. Dorothy Wertz, the chief editor, acknowledged the error.

  153. Newsweek August 24, 1998 (page 17) published a cartoon by Jack Ohman (Oregonian editorial cartoonist) indicating that left handed DNA has infiltrated the cartoon world. It is of some interest that DNA does replicate by the method depicted on the right. The little device at the bottom corresponds to the "helicase" enzymes that use the energy molecule ATP to open the DNA. (Thanks to David G. Rhodes, University of Connecticut for finding and scanning the image!)

  154. National Institutes of Health 2nd Gene Therapy Policy Conference Gene therapy policy is now being considered for left handed DNA people. Apparently the poster for the Third conference is on the same topic.

The second correction (Science 4 December 1998: 282 (5395): 1827) is correct. Thanks to our sysadmins, both work as of 1999 Feb 16.)
  158. QIAGEN advertisement in Science on Friday 13 November 1998: 282 (5392):1224, curiously placed on the back side of the page announcing this web site . Just in case you were not sure which way the DNA turns, they announce a new hot line: "Questions about molecular biology?" Below this they show a red phone with a left handed cord of DNA. As John Ludwig, a Microsoft vice president in charge of Java development wrote in an internal email, ``Subversion has always been our best tactic. Subversion is almost invariably a better tactic than a frontal assault . . . it leaves the competition confused, they don't know what to shoot at anymore.'' The CT people have gotten really subtle. (Thanks to Paul Brown BROWNP@cder.fda.gov for pointing this scary one out!)
  159. U. S. News & World Report (November 23 1998 page 58), "Miracle Vaccines". They report that certain pathogens have been discovered to contain both left and right handed DNA. To fight these, the right handed DNA can be extracted and used in a naked DNA vaccine, as shown in this diagram. People with right handed DNA will then express antigens against the right handed proteins on the surface and therefore will be protected from the disease. This is a very smart use of molecular technology! It is still mysterious how these pathogens live using both kinds of DNA.

    1999

    Our Story So Far: The story line, if you have not had time to follow the previous 150 or so entries (!) is my slow realization that earth is being invaded by left handed DNA people ...

  162. Invitrogen web page background as of 1999 Jan 9. The company specializes in left handed DNA products.
  163. Altheatech advertisement in BioTechniques Vol. 26, No. 1, January 1999. They have purified left handed DNA from a purple and orange snake. This appears to be a native of the CT planet! Jane Maxwell, Vice President, Sales and Marketing, indicates that they discovered this error after they it had gone to print. This image is posted with permission.

  164. Time January 11, 1999, page 49. Genetic footprinting of left handed DNA was reportedly done by Alec Jeffreys in 1984! (Thanks to Antonio Regalado, regalado@mit.edu, Associate Editor Technology Review Massachusetts Institute of Technology, Bldg. W59-200, 201 Vassar Street, Cambridge, MA 02139 for sending me the image.)

  165. The January 1999 Volume 14 Number 1 cover of the journal Spectroscopy indicates that spectroscopic studies are now being performed on left handed DNA. Other than polarization effects, I would expect this to be the same as right handed DNA, but the article doesn't seem to mention it. (Art direction by Sandy Kupsch, image number 59175 from PhotoDisc, Inc. Use their search engine with the word "DNA" to find their inverted DNA image.) The error was acknowledged by Mike MacRae, the Spectroscopy editor and Jennifer Yerkes of PhotoDisc. (Thanks to David G. Rhodes, University of Connecticut for finding sending me the journal issue!)
  166. TIBS 23 December 1998 page 493 cartoon by Simon '98, shows Sherlock looking at a left handed DNA with a magnification glass. He says "Excellent try, my dear Watson, but ... could you bring me a mirror, old boy?" Are people are beginning to realize that there has been a CT invasion? This image is posted with permission.
    (Click on image for a larger version.) Thanks to Jamie Simon (jamie_simon@qm.salk.edu) for drawing this cartoon and for permission to put it on the web.)
  167. The National Library of Medicine's impressive collection of original significant scientific papers Profiles in Science shows that not only did Avery discover DNA but he also had spectacular insight into the existence of left handed DNA.
    This image is posted with permission.
    as of 1999 January 28. They acknowledged the error and said: "However, as luck would have it, it was replaced yesterday with a different image which does not contain DNA."
  168. The UCSF Digital Library has a banner that may be left handed DNA. (Thanks to Paul Hengen (pnh@sirius.com) for pointing this one out!)
    as of 1999 January 28
  169. Lawrence Livemore National Laboratory's Biology and Biotechnology Research Program also has a banner that is definitely left handed DNA. (Thanks to Andy Hockey (a.hockey@ucl.ac.uk) for pointing this one out!)
    as of 1999 January 28. The web site was revised and the original image is not on the main page, but it still is at http://www-bio.llnl.gov/bbrp/gif/dna48.gif (Thanks to Keith Ball, kdb@maxwell.ucsf.edu, http://rainbow.uchicago.edu/~kdb1 for pointing this out!)
  170. Access Excellence (the excellent educational program of Genentech) has discovered a relationship between left and right handed DNA! Apparently under certain conditions (patent pending?) right handed DNA can replicate to produce both forms. (Thanks to Stan Metzenberg (smetz@gte.net) for pointing this one out!) as of 1999 January 30. (2000 December 31: Notice the mismatch between the newly opened strands; this mysertious replication mechanism has not been determined.)
  171. SIMPOSIUM INTERNACIONAL DE BIOTECNOLOGÍA APLICADA Y BIOÉTICA 24, 25 y 26 de marzo de 1999. This appears to be a symposium on the biotechnology of left handed DNA. as of 1999 February 24
  172. This case was corrected and removed by request.
  173. The cover of Oncogene Research Products' 1999 General Catalog "Tools for Biological Research" shows that left handed DNA is controlled by the signal transduction proteins fos and jun, and that proteases can be synthesized from left handed DNA. As shown in the figure to the right, which was taken from their Methods section, they also provide methods for working with left handed DNA.
    as of 1999 March 3
    This image is posted with permission.
  174. The cover of Bioinformatics has a left handed spiral made out of 1s and 0s. I initially didn't include it in this collection because it has no ladder of bases in the middle so it could be anything, not necessarily DNA. However, the editor Gary Stormo says that it was intended to be "digital DNA" and that they are planning to fix it. (Thanks to Gary Stormo, Stormo@colorado.edu, for pointing this one out!)
    as of 1999 March 16
  175. The home page of the NIH National Institute of Mental Health (NIMH) GENETICS RESEARCH BRANCH has a left handed DNA, reflecting the increasing need to help people with mental problems who have left handed DNA. Why, they are right in my own "back yard" since I'm at NIH! (Thanks to Ron Edgar, ron@imagic.weizmann.ac.il, for pointing this one out!)
    as of 1999 March 22
  176. The home page of the NIH National Human Genome Research Institute has both left and handed DNA, to indicate that the effort to sequence the human genome has been changed to sequence both the left and right handed genomes. This is another NIH site!
    as of 1999 March 22

  177. The NIH National Institute on Aging appears to have a new focus, to study whether people tend to age more rapidly due to left handed DNA. Recent Press Releases are on Mild Cognitive and Memory Impairment (3/15/99) and Delirium (3/3/99). This is the third NIH site in a row! Why am I getting dizzy?
    as of 1999 March 24

  178. Invitrogen has some unwound DNA on its 1999 Product Catalog cover that winds up to left handed DNA. What a mesmerizing pretty cover ...
    as of 1999 March 25
  179. The QIAGEN web site product guide page has at least four separate left handed DNAs!





    Each of these points to a page with a left handed banner such as:
    I'm glad to see a company devoted to supporting the DNA isolation needs of molecular biologists studying Left Handed DNA ... *GAK* what am I saying?? Have the CT people infected my mind? Oh, no!! (Thanks to Nico Gey van Pittius, ngvp@gerga.sun.ac.za, for pointing this one out!)
    as of 1999 March 25
    QIAGEN has acknowledged the error and offered to supply the previous images! Thanks!
  180. Thanks to Ron Edgar, ron@imagic.weizmann.ac.il, for pointing out a web site that refuses to be identified.
    as of 1999 March 25
  181. As shown in Roche Molecular Biochemicals' Apoptitoc Pathway Chart, left handed DNA is also degraded by this process. It has been suggested that this is related to the process by which right handed DNA humans are being converted to left DNA handed humans. However, the stronger hypothesis is that the left handed DNA humans are not from earth, as indicated by a report from 10 years ago (Thanks to Nikolaj Vibede, nikolaj.vibede@farmakol.ku.dk, University of Copenhagen, for pointing this one out!)
    as of 1999 March 26
  182. The home page of the NIH National Institute on Alcohol Abuse and Alcoholism According to the person who found this case, it "is rather poor in resolution but it attempts to show a male and female under heavy abuse of alcohol which causes them to see a left handed DNA." (My anonymous source asks: "Am I becoming sufficiently cynical?" No, but you are getting there!)
    as of 1999 March 27
  183. My underground guerrilla-warfare anonymous source also tells me that "The Kesseli Lab at University of Massachusetts at Boston http://fisher.bio.umb.edu/ has three left DNAs at one page... two are happily rotating to the right (is that the biological function of left D.N.A (aka A.N.D) ?) They also explain how to sequence left handed DNA in the scheme (at the middle right on the page) what are they teaching these kids?" Note how there are three phosphates in a vertical column with no distinction between the major and minor grooves ... is this triplex left handed DNA? If so, it would be the first reported case!
    as of 1999 March 27. 2000 December 31: I was alerted by Jennifer Forman that the left handed DNAs have been removed from the lab pages!
  184. The magazine Portable Design reports on page 12 of their February 1999 issue that "Lab-on-a-chip analyzes DNA", and show a diagram of a Labrador retriever happily sailing on a potato chip, with a left handed DNA leash.
    as of 1999 March 27
  185. A QIAGEN advertisement in Nature (28 January 1999, p. xviii) indicates that left handed DNA has now been isolated from tomato, tobacco, maize, potato, wheat, barley, poplar, petunia, geranium, spinach, arabidopsis, elm, pine, rhododendron and oak plants. Apparently plants are being converted also.
    as of 1999 March 30
  186. A PharMingen International advertisement in BioTechniques (Vol.25, No 2 August 1998) was brought to my attention, but it is essentially the same as the one in 1996. However it led us to their web site where a beautiful left handed DNA being bound by an antibody graces the cover of their new 1999 Research Products Catalogue. Such detection schemes will allow more rapid distinction between left and right DNA people for tax purposes. However this new use of genetic technology has ethical dimensions that are being hotly contested.
    as of 1999 April 1

  187. Clinmark dotcom's link page points to a number of companies that do clinical research on left handed DNA people. Their home page also has a tiny left hand DNA link. (Thanks to Gorilla Guerilla for pointing this one out!)

  191. The cover of the journal European BioPharmaceutical Review for September 1998 and for 1999 This image is posted with permission. has a pretty left handed DNA running across it to indicate that this industry is now using left handed DNA in new pharmaceuticals. (The original is more clear than this gif.) (Thanks to Nikolaj Vibede, nikolaj.vibede@farmakol.ku.dk, University of Copenhagen, for pointing this one out!)
    as of 1999 April 15. They acknowledged and will probably be correcting the cover
  192. The New York Times Science section page D10, Tuesday April 20, 1999 (National Edition) reports that Snips will be used to identify left handed DNA people. (Thanks to Jack Tessman, Emeritus Professor of Physics, Tufts University, Medford MA 02155, jack@silcon.com for pointing this one out!)
    as of 1999 April 22

  194. MWGAG BIOTECH sent out a flyer with a left handed DNA (blue and green), and has another on their home page.
    as of 1999 April 26.
    The same images appear in an advertisement in Biotechiques vol 27, No.1 July 1999 pages 44, 45 and 51. (Thanks to Ilya Lyakhov, lyakhovi@ncifcrf.gov, for pointing this one out!)
    as of 1999 July 21
  195. An advertisement by JBL Scientific found at the web magazine HMS Beagle shows the very fast injection of DNA into a cell. If you watch carefully you will see that it is left handed. (This is most easily done by opening just the image and then reloading repeatedly.) JBL was "unable to attain a release from the graphics author" so I can't show you the image.
    as of 1999 May 10

  196. A book "Applied Molecular Genetics" by Roger L. Miesfeld (John Wiley & Sons, 1999), has on its cover the same left handed DNA that appeared on the January 1999 cover of Spectroscopy (Thanks to Denise Rubens rubens@ncifcrf.gov for pointing this one out!)

  198. In Figure 1 of an article in Science (Science 284: 757 30 April 1999) we learn that reverse endrocrinology is now being done on Left handed DNA containing people. The so-called "orphan nuclear receptors" are genes that look like the receptor for a hormone, but no hormone has been identified yet. Perhaps the problem is that the hormones are enantiomers (reverse handed)?

  207. The Nolan Lab at the Stanford University Medical center works on helper-free left handed DNA retrovirus producer lines. This follows the discovery of left handed reverse transcriptase, which can transcribe left handed RNA in to left handed DNA.
    Garry Nolan reports that "By the way that is not left-handed DNA in our picture. It is ladder with colored bars that I took a picture of in a mirror and then used adobe photoshop to invert and paint it so it would look cool as a graphic to FOOL people into thinking we were actually working on left-handed DNA. You fell into our trap."

  214. The front cover of the Summer 1999 Life Science Edition catalogue from Daigger announces "DNA Daigger's New Attractions". Jack Tessman points out that
    "There is a DNA helix in the upper, outer corner of every one of the catalog's 28 pages. Except for the cover (page 1) which shows [two] right- handed DNAs, all the odd pages show left-handed DNA. The even pages show right-handed DNA. In addition, sprinkled throughout are little men in lab coats that partially cover skeletal [DNA] structures which are right- handed wherever the little man is holding a pointer in his left hand, and left-handed wherever the little man is holding a pointer in his right hand."
    I note also that the button on the man's lab coat switches sides depending on which hand holds the pointer. If I recall correctly, men's clothing (and the lab coats we have in the lab here) have the button on the right side when unclosed. This corresponds to the right handed DNA pictures. So we might infer that the original artist drew the image the "right" way, and it was flipped for publication.

WARNING, SPOILER: Actually, the Martians seeded earth with right handed DNA, then left because Mars was dying. This is consistant with them coming back now to take over. They must have messed up somehow when they seeded Earth! Or maybe it was a nifty trick to identify and eliminate native flora?

A. Crompton, nigel.crompton@psi.ch points out:
    Your literal translation is of course correct but the actual meaning is not "measure of man". The phrase "nach Mass" means "as you choose to have or design something". Perhaps a more appropriate way to translate the phrase would be "Artificial contructrion of Man".

    "if this is truly the image which is on the stamp, then when the stamp is dipped in ink and stamped on a page it will reverse, making the DNA right handed."
    What an interesting point!!! The stamp itself would be correct! I corrected the link and then located it under "Things". The DNA is indeed shown as left handed in "Things". Then I checked out the "Messages" category and found that the messages can be read. This means that they are displaying what the stamp will print, not what's on the stamp itself. The stamp itself must be correct, but the images printed from it are reversed to be left handed ... new as of 2001 April 18; revised link 2008 Nov 21.
