With only about 1,000 pandas left in
the world, China is desperately trying to clone the animal and save the
endangered species. That’s a move similar to what a Texas A&M University
researcher has been undertaking for the past five years in a project called
"Noah’s Ark". Dr. Duane Kraemer, a professor in Texas A&M’s College of Veterinary Medicine and a pioneer in embryo (胚胎) transfer work and related procedures, said he salutes the Chinese effort and "I wish them all the best success possible. It’s a worthwhile project, certainly not an easy one, and it’s very much like what we’re attempting here at Texas A&M—to save animals from extinction". Noah’s Ark is aimed at collecting eggs, embryos, semens (精子) and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Kraemer says t A.
