Of Survival and Science
Lundi 06 Octobre 2008 - 14:30 - 1 mois, 2 semaines depuis - 5 lectures - Presse spécialisée - Scientific American
Editor's note: This story was originally posted in the August 1999 issue, and has been reposted to highlight the long intertwined history of the Nobel Prizes in Scientific American.In 1996 Japan's Inamori Foundation asked Mario R. Capecchi to review his life and work in an acceptance speech for the prestigious Kyoto Prize. Capecchi dutifully described his pathbreaking research on a precision method for insertion or deletion of genes in mice. The most compelling part of the talk, however, had nothing to do with mouse chimeras or positive-negative selection. Rather Capecchi recounted memories of a childhood with the makings of a script Italian actor/director Roberto Benigni might use as an encore for his Academy Award-winning Life Is Beautiful. [More]

Burning incense has accompanied religious ceremonies since ancient times. Its fragrant presence may be more than symbolic, however--a May 20 study in the FASEB journal suggests that a chemical commonly found in incense may elevate mood.Raphael Mechoulam of the Hebrew University of Jerusalem and his colleagues injected mice with incensole acetate, a component of the resin of the Boswellia plant. This resin, better known as frankincense, is an ingredient in Middle Eastern incense. The chemical reduced anxiety and depressive symptoms in the mice. In the anxiety test, for example, injected animals were less fearful of open spaces as compared with mice that were given a placebo. [More]
