  2. An advertisement for the journal MCB on the back cover of the Journal of Bacteriology January 2000, volume 182, Number 2, indicates that a paper on left handed DNA fused to right handed has been accepted. Has there been interbreeding?
    new as of 2000 January 11

  3. At the web site http://www.genebrowser.com/ if one clicks on the NTE Vector Core Facility link, one will get a pdf document that has two left handed DNA molecules that the company will routinely make for you. (Thanks to Steve Mitchell, smitchell@urogenesys.com, for pointing this one out!)

  5. Mergen Ltd advertisement in Nature (13 January 2000, no 6766, p. 142). This is another clone of an earlier DNA image which has been cultured by the PhotoDisc company. Is it taking off exponentially? Three of Photodisk's images are now left handed, two are right handed although they were alerted to this problem by me a year ago.

  9. The upcoming movie "Let there be life - Mission to Mars" from Touchstone Pictures has some footage of left handed DNA on Mars. Have we found the source?
    new as of 2000 February 12
    2000 April 10: Steve Ward (sward@UMDNJ.EDU) saw the movie and points out that "Every example they used was left handed - both the M&Ms and the computer generated model." At one point one person says "That DNA looks human." when viewing a left handed spiral no more than 10 bases long. DUMB!!!! 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?

  37. On Tuesday June 27, 2000 The New York Times announced on their front page that the entire sequence of a left handed DNA person has been completed! Since right handed people are being exterminated there are no plans for doing their sequence.

  43. Der Spiegel (15/2000, page 172) published an article "MENSCHEN NACH MASS" literally "HUMANS AFTER MEASURE", I suppose meaning the "Measure of Man" - left handed DNA man that is, since behind the da Vinci but young modern human is a left handed DNA. new as of 2000 July 23 Nigel E. 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".

Entitled "Genes that Let Illness In", by Jerome Groopman of Harvard, the story mentions "the pernicious seeds ... presumed to be present in the blueprint of the person's DNA ..." Those of remaining few of you with right handed DNA had better join the underground now, otherwise jail is what is in store for you, ... or worse? new as of 2000 July 25 (Thanks to Jack Tessman, jack@silcon.com, for pointing this one out!)

Researcher in Residence is a cool program, run by the Association for Science Education (UK), in which (left handed DNA) PhD students work with teachers and pupils in schools. new as of 2000 Oct 10 (added 2000 Dec 15) (Thanks to Dean Madden, dean@madden.tele2.co.uk, for pointing this one out!) 2002 Aug 31: I received a note from Steve Wooding who says:
    I was intrigued by your 'Left Handed DNA Hall of Fame' and amused to see that the Wellcome Trust features by proxy: we are a co-funder of the Researchers in Residence initiative that features at number 72. However, things have moved on and the scheme is no longer run by the ASE and is now run by the Sheffield Hallam Department of Science Education, it also has a new logo. While I have no problem with you continuing to display the old logo along with the description, I'd appreciate it if you could put a note that the organisation running the scheme has changed and include a link to the new scheme (http://www.researchersinresidence.org), just in case one of our students is reading your page and is interested in getting involved.

  73. Maggie Fox of Reuters reported on October 12 that the left handed DNA mouse genome was almost mapped. For this great 'nearly' event (we can have as many of these as we want!), MSNBC put together a cute moving graphic to demonstrate how DNA sequencing is "almost" done. They called it MappingDNA. Unfortunately you will need Flash on your computer to see it. new as of 2000 Oct 13 (added 2000 Dec 27) (Thanks to David Lloyd-Jones, icomm5@netcom.ca for pointing this one out!) The image was captured in 2001.

  74. As reported in Science (20 Oct 2000, vol 290 (5491) p. 444) GMP Genetics, Inc. has demonstrated that there exist diploids that have one DNA strand left handed and the other right handed. Apparently the creatures live! The image that demonstrates this is in their PDF Brochure The same image was reported earlier by Infectio. new as of 2000 Nov 1

  81. The Chemical & Engineering News "(July 31, 200) featured on its cover and page 31 a left handed CPK (!) molecule on an article on Proteomics--From Genes to Proteins. The error was highlighted by Christopher J. Welch of Merck, Rahway, NJ. Your website was mentioned." The correction is Aug 14, 2000 CEN p. 8. new as of 2000 Nov 28 (Thanks to Yock Chai Toong, yctoong@tm.net.my for pointing this one out!)

  82. The journal Chemistry in Britain "did the same on its front cover, back cover and on page 46 of the May 2000 issue. The error was pointed out by J.D. Dunitz and E. Hibronner of Switzerland in a letter to editor on July 2000. It is not surprising that Dunitz could spot the error for he is a very well known X-ray crystallographer." new as of 2000 Nov 28 (Thanks to Yock Chai Toong, yctoong@tm.net.my for pointing this one out!)

  83. The American Association of Pharmaceutical Scientists web site had a left DNA handed banner:

  84. In addition to the three left handed DNA images already noted, surprisingly there are three more cases of similar left-handed images on page 37 for a total of 6 images in Nature 408 (2000)! new as of 2000 Dec 1

(The two files are exactly identical.) new as of 2000 Dec 14 (Thanks to Ronnie Hunag, jch@stag.gov.tw, for pointing this one out!)

  88. "New media for the new biology" announces GenomeWeb. The new media are indicated by a left handed DNA in the background and a left handed spiral over their name. It is nearly 2001, after all, and it is reported that 99% of H. sapiens now have left handed DNA. Note that the manditory deadline for substitution by your reverse clone is approaching, on January 20 of 2001. new as of 2000 Dec 15.

  89. Steve Ward reports: I just returned from Cell Biology where I saw two left handed DNAs at booths of companies and both of them knew it. One was apologetic and promised to change it, so I promised her I would not report it. The other company knew it, and even had a three dimensional space filling model of left handed B-DNA that was intentional! The problem was that the logo was originally a short, left handed helix that looked vaguely like DNA, so to have the transformation from the logo to the 3D model, the 3D model had to be reversed! Their website (http://www.biosearchtech.com/) does not have the 3D model, but the left handed logo is there. Biosearch Technologies provides chemistries for left handed DNA genomics. new as of 2000 Dec 15 (Thanks to W. Steven Ward, wward@hawaii.edu, for pointing this one out!)

  94. An advertisment for WebMD (found while constructing the MSNBC Left handed mouse report) shows an intriguing left handed DNA running like blood vessels up a right handed arm. This is a depiction of the process of clone-converting (cloneverting) you from left to right handed DNA. new as of 2000 Dec 27

  96. As noted in Science (volume 289, page 2369, 29 September 2000) the cover of the AAAS report Human Inheritable Genetic Modificiations shows that left handed DNA is inheritable. (Right handed DNA is not because we are becomming extinct.) new as of 2001 Jan 8

For your first visit to the Left Handed Hall of Fame page I suggest that you follow the story over all of the years. After that you can look at each year individually from the table below. Note: just because a year has gone by does not mean we haven't found more examples for that year!

1997 and 1998 were bumper crop years
and 1999 beat them more than 2 fold. 2000 was a record year, thanks to help from friends around the world (60 of the 97 cases, 63%!). 2001 exceeded even that record! 2002 was lower - are we making headway?
