The first full-length motion picture in the U.S. filmed outdoors was released by Fox Film Corporation. Re-titled as In Old Arizona, it was adapted from a short story by O. Henry, “The Caballero's Way.” The black and white Western was a box-office hit, starring Oscar-winning Warren Baxter as “The Cisco Kid,” a carefree Mexican bandit who outwits the sheriff trying to capture him. A review in the New York Times referred to “the novelty of the Movietone,” listed various incidental sounds and particularly noted the welcome new consideration that the sound of galloping grew fainter and fainter in the distance. Film locations included Zion National Park, Bryce Canyon, the Mojave Desert in California and San Juan Capistrano mission.

American researchers announced they have cloned calves that may produce medicinal milk. Dr James Robl at the University of Massachusetts and Dr Steven Stice of Advanced Cell Technology were the first to clone cows from fetal cells in which human genes were spliced into cattle DNA. Creating two identical, genetically engineered calves are a step towards the mass production of human drugs in animals. Their goal was to turn cows into drug factories, mass producing milk that contains human proteins important for treating human diseases. The scientists used a variation on the techniques previously used in Edinburgh, Scotland, to create the cloned sheep Dolly. Cows would be better producers of the proteins than sheep because they make more milk.
