Robert Lefkowitz de HHMI comparte el premio con Brian Kobilka por estudios sobre los receptores acoplados a proteínas G.
Only a few animals, such as songbirds, whales, and dolphins, are known to be vocal learners, modifying the sequence or pitch of their sounds based on what they hear from other members of their species. New evidence suggests mice can be added to that list.
HHMI's Robert Lefkowitz shares prize with Brian Kobilka for research on G-protein coupled receptors.
