Delegates to an international species conservation conference in Bangkok, Thailand, this week have agreed to limit the trade of shark fins and meat.

NPR's Christopher Joyce reports that government representatives to the Convention on International Trade in Endangered Species, or CITES, have agreed to put the porbeagle, oceanic whitetip, three kinds of hammerhead shark and two kinds of manta ray on its Appendix II list, which places restrictions on fishing but still allows limited trade.

In her new book, Frankenstein's Cat: Cuddling up to Biotech's Brave New Beasts, science journalist Emily Anthes talks about how the landscape of bioengineering has expanded since Dolly the Sheep was cloned in 1996. Scientists, she says, are now working to create pigs that can grow organs for human transplant, goats that produce valuable protein-rich milk, and cockroaches that could potentially serve as tiny scouts into danger zones for the military.

Ever since she was a small child, Samantha Grimaldo has had to carry her voice with her.

Grimaldo was born with a rare disorder, Perisylvian syndrome, which means that though she's physically capable in many ways, she's never been able to speak. Instead, she's used a device to speak. She types in what she wants to say, and the device says those words out loud. Her mother, Ruane Grimaldo, says that when Samantha was very young, the voice she used came in a heavy gray box.

Are There Too Many PhDs And Not Enough Jobs?

Originally published on Mon March 11, 2013 7:50 am

Our country needs more people with science, math and engineering degrees — at least, that's the common refrain among politicians and educators.

American students lag behind the rest of the world when it comes to math and science test scores, and the president and others have called for a change in immigration laws that would make it easier for people who come to the U.S. to get technical degrees to stay in the country permanently.
