Researchers Enlarge Mouse Brains With Bits Of Human DNA

Researchers have managed to dramatically enlarge the brains of mice by inserting bits of human DNA into the rodents. The research, published in the journal Current Biology, is a step toward isolating the genetic element responsible for human intelligence.

Researchers from Duke University isolated a genetic sequence known as HARE5, which is present in two different forms in both chimpanzees and humans, EurekAlert reported Thursday. They introduced both versions of the sequence in two groups of mice.
