Chimp and human lineages may have split twice as long ago as thought
New estimates of chimpanzee mutation rates suggest humans and chimps last shared a common ancestor 13 million years ago.

Bowhead whales may unlock the secrets to a long, healthy life
Analyzing the genome of the bowhead whale may help scientists understand how the animals live for more than 200 years.

Human evolution tied to a small fraction of the genome
Natural selection has concentrated on a small portion of the human genome, and mostly not on genes themselves.

Study of psychiatric disorders is difficult in man and mouse
Studying human psychiatric disorders in animals presents a challenge. A new study highlights one of the ways scientists can study human mutations by slipping them into mice.
- Genetics
DNA disorganization linked to aging
Changes in the way that DNA is tightly packed in cells leads to mayhem that promotes the aging process.
- Neuroscience
Electrical zap of cells shapes growing brains
The electric charge across cell membranes directs many aspects of brain development, and changing it can fix certain brain birth defects.
