Monkey flossing

Tuesday, July 27th, 2010

Monkey flossing became a formal practice, at least experimentally, in the late 1970s, thanks to a dentist named Jack Caton. Twenty years later, a physician, David C Sokal, inspired by the monkey flossing, patented a top/bottom flossing-reminder and floss-dispensing device for humans. Monkeys themselves apparently began unassistedly flossing not long afterwards. But in all probability those animals were not influenced by either Caton’s experiment or Sokal’s invention….

DNA Faking for Criminals and Murder Novelists

Monday, July 26th, 2010

Master criminals and murder novelists, many of whom felt hemmed in by technical limitations, can feel relieved by the news of new DNA technology:

Authentication of forensic DNA samples,” Dan Frumkin, Adam Wasserstrom, Ariane Davidson and Arnon Grafit, Forensic Science International Genetics, Volume 4, Issue 2, Pages 95-103 (February 2010). (Thanks to Ed Yong for bringing this to our attention.) The authors, at Nucleix Ltd., Tel Aviv, Israel, and at the Division of Identification & Forensic Science, Israel Police, explain:

“the disturbing possibility that DNA evidence can be faked has been overlooked. It turns out that standard molecular biology techniques such as PCR, molecular cloning, and recently developed whole genome amplification (WGA), enable anyone with basic equipment and know-how to produce practically unlimited amounts of in vitro synthesized (artificial) DNA with any desired genetic profile.
