Cancer's Genome
For the first time, scientists can track the precise genetic changes behind an individual case of cancer. Such information provides a picture of how tumor cells originate and evolve. And it could change the way we treat the disease.
The Human Genome, a Decade Later
Ten years after scientists finished mapping our DNA, they have many unanswered questions.
Stem Cells Made with RNA
A new technique could provide safer cells for human therapies
Long-Term Glucose Monitoring
Implanted devices measure blood sugar continuously for many months.
Brain Control
Ed Boyden is learning how to alter behavior by using light to turn neurons on and off.
From the Labs: Biomedicine
New publications, experiments and breakthroughs in biomedicine--and what they mean.
A Family Mystery, Solved by a Genome
Physicians can now use DNA sequencing to uncover the causes of rare genetic disorders.
Preventing HIV
We should treat high-risk populations before they have been exposed.
