Evidence is growing that your DNA sequence does not determine your entire genetic fate. Joseph Nadeau is trying to find out what accounts for the rest.
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.
Ten years after scientists finished mapping our DNA, they have many unanswered questions.
A new technique could provide safer cells for human therapies
Implanted devices measure blood sugar continuously for many months.
Ed Boyden is learning how to alter behavior by using light to turn neurons on and off.
New publications, experiments and breakthroughs in biomedicine--and what they mean.
Physicians can now use DNA sequencing to uncover the causes of rare genetic disorders.
We should treat high-risk populations before they have been exposed.
Can a drug extend good health and postpone the effects of aging?
