Is junk food addictive?

摘要

For the first time, researchers have sequenced the genome of a songbird, reports an international consortium of researchers {Nature 464,757-762; 2010). This songbird, the zebra finch, is already an established animal model in several biological fields. Other than songbirds, only a few animals, such as whales and humans, can learn vocalizations. Researchers can now study this songbird's genome to better understand the development of learned vocalizations in songbirds and other animals.
