Dr. Ian Wilmut, the Edinburgh embryologist who made history last year by becoming the first researcher to create a living mammal by cloning from the DNA of an adult, will speak twice at UC Davis next week. Wilmut will appear as part of the Storer Life Sciences Lectures. On Monday, May 18, his topic will be "Are there any limits to the cloning of animals?" On Tuesday, May 19, his topic will be "The uses of cloning in biology and medicine." Both lectures will be held in Freeborn Hall at 4:10 p.m. Since the birth of Wilmut's lamb, named Dolly, other researchers have announced the cloning of a bull, cows and rhesus monkeys. But Wilmut continues to be the most famous figure in the field, and his lectures are very well attended. For that reason, admission to the 1,300-seat hall will be limited to ticket-holders. All tickets for the public have been distributed. Because the hall may be full, members of the media also need tickets to attend the lectures. Even photographers and camera operators who will not be seated need tickets. Please make reservations by 4:30 p.m. tomorrow, Thursday, May 14, with Sylvia Wright in the News Service (see below). A news conference will precede the Monday lecture. It will take place on the Freeborn Hall stage from 3 to 3:30 p.m. Even media who plan to attend the news conference but not the lecture will need a ticket for admission. As usual, media may park as long as necessary for free on campus in any legal parking space. Leave a media business card on the dashboard of any unmarked vehicle.
