New research indicates individual human neurons may harbor up to 1,000 genetic mutations.
HHMI scientists have devised a technique to identify hard-to-find gene mutations that crop up in a fraction of the body's cells.
The clear and watery substance that bathes the brain and spinal cord is enough to support the growth of neural stem cells in the lab.
A newly identified gene mutation is one of only a handful of mutations outside the X chromosome to be linked to intellectual disability.
By focusing on large families in which both parents share a recent ancestor, scientists have honed in on rare mutations that had remained elusive in previous studies.
The journal Science has announced that the scientific ”Breakthrough of the Year" is evolution in action. Recent experiments by four HHMI investigators were among those mentioned by Science as having provided evidence of evolution in action during the past year.
