To Save Some Species, Zoos Must Let Others Die

ST. LOUIS -- With fluorescent yellow eyes and tufts of hair sticking straight up behind their ears, Bonner and Etienne look like slightly crazed old men. These riotous and chatty lemurs--known for elaborate rituals that include grooming and braying--once ranged across eastern Madagascar.
Now scores of these black-and-white ruffed lemurs are being bred here at the St. Louis Zoo and at other zoos across the United States as part of a broader effort to prevent their extinction.
But Ozzie, a lion-tailed macaque, will never father children. Lion-tails once flourished in the tops of rain forests in India, using their naturally dark coloring to disappear into the height of the jungle. Though there are only about 4,000 remaining in the wild, not one among Ozzie's group here in St. Louis will be bred. American zoos are on the verge of giving up on trying to save them.

PODCAST & VIDEO: 3D Printing Replacement Body Parts
Regenerative medicine, a fledgling field with the aim of regrowing parts from a person’s own cells, is being amplified with 3D-printing technology, which can now use organic materials to create scaffolds that cells need to grow into their final forms. Richard Wysk, a professor of industrial and systems engineering at North Carolina State University, discusses the latest successes with this research, and the timeline for creating more complicated structures.
