Our Story So Far:
The story line, if you have not had time to
previous 769 or so entries
(!) is my slow realization that earth
is being invaded by left handed DNA people ...
NOTE: I am currently NOT adding entries with images - too much else to do!! Please enjoy a visit to my web site and read my papers.

A few years ago I attended a Mechanisms of Cancer symposium at Cold Spring Harbor Labs, and James Watson stood up for an introduction. He commented that when he was first shown the newly constructed Grace Auditorium in 1986, he immediately noticed that the wall trim was festooned with a left-handed double helix. He insisted that it immediately be torn out and replaced with right handed helix artwork.
The current appearance is visible at the top of this stock photo:

In the opening sequence of 'Prometheus' there is an implication of a biogenetic event involving alien DNA. Apart from a dodgy double helix, the key point is that the DNA twists in a, you guessed it, left handed helix. Considering that they later make much of the fact that the alien's DNA is a perfect match for human DNA, it provides further 'evidence' of the alien conspiracy to replace all the right-handers!!!
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!
