Dolly Shows New View of Clones, Aging
May 27, 1999
The first molecular studies ever
conducted on Dolly, the 3-year-old sheep cloned
from a 6-year-old ewe, have found that Dolly's
cells are, in essence, at least nine years old.
Japanese Clone 8 Calves From Cow
December 9, 1998
Scientists in Japan have cloned several calves from a single adult cow, the

and the most commercially important animal to be cloned to date.
Mass. Firm Says It Created Embryo Out of Human, Cow Cells
November 13, 1998
Scientists, ethicists and federal regulators scrambled to sort out the many
controversial issues raised by a small biotechnology company's
announcement that it had used cloning techniques to create an embryo out
of human and cow cells.
Last Cow of Rare Breed Is Cloned in New Zealand

Mouse May Have Been Cloned
June 27, 1998
Ever since researchers in Scotland announced 15 months ago that they had

Man Who Cloned Sheep May Try Again
February 14, 1998

Cow Eggs Play Crucial Role in Cloning Effort
January 19, 1998

A Chicago scientist, Richard Seed said he assembled a team of doctors that is prepared to clone a human being before Congress has a chance to ban the procedure.
Near-Term Benefits of Cloning Likely to Be Medical
March 29, 1997
The routine genetic modification of animals to create healthier food products may be the most dramatic legacy of the remarkable cloning experiment in Scotland that produced Dolly, but Dolly's creation is likely to bring less visible but profound changes in medicine.
Scientists Achieve Cloning Success
February 24, 1997
Scottish researchers' startling achievement, long thought to be biologically impossible, was the first cloning of an adult mammal, and the birth of a lamb named Dolly.
