As a chemist and one of the 'groaners' about DNA's oft-misrepresented chirality (Nature 467, 789; 2010), I have made a point of complaining whenever I find a left-handed helix in a biotech company logo, on an international charity's website or in an undergraduate textbook — to name a few offenders. But until now, I have never seen the mistake cast in concrete and the size of a house.
On a recent visit to the Australian National University in Canberra, look what I found as part of their medical-faculty building (pictured, top). Luckily, a little way along the street I saw that the geneticists had got it right (bottom).
Then I thought, “No: one right and one wrong, not a statistically valid result.” I must resume my campaign.
