World's Smallest Wedding Rings Made of DNA

Posted by samzenpus on from the GCAT-grade-stone dept.

fangmcgee writes "Nerd love alert: German researchers have just created the world's smallest wedding rings, measuring less than a thousandth of the width of a human hair. Goethe University professor Alexander Heckel and his doctoral student Thorsten Schmidt made the artificial structures from two interlocking loops of DNA — known as catenane — in a single drop of water."

    In what way are these rings "wedding rings"?

      In no way whatsoever. The wedding ring reference was a joke made by the post doc who did this research. The press being what it is, used the joke. Then, at the end of the "article," the author makes an engagement ring joke, despite engagement rings not being the same as wedding rights at all.
