Durham, North Carolina (TFC) – Scientists at Duke University have spliced a human DNA sequence into mice for the purposes of giving them larger brains.

The experiment was a success and caused a 12% growth in brain matter. While brain size is not solely responsible for increased intelligence, it plays a large part. The gene sequence used is known as HARE5, and is part of a collection of gene sequences that regulates the activity of other genes.

The researchers hope to gain insight into conditions like Autism or Alzheimer’s. Either way, it’s time to build a better mousetrap.
