1000 Genomes pilot a hit with geneticists
The first stage of a project to probe human genetic diversity has found millions of new variations.

Pancreatic cancer years in the making
A decade elapses from the first cancer-related mutation to tumor formation, and several more years pass until the disease spreads to other organs, a new study finds. The work raises the possibility that a usually deadly malignancy can be treated before it’s too late.

Protein implicated in many cancers
A hormone receptor that shows up in 11 tumor types might make a good target for drugs, a new study suggests.

Gene therapy for depression
Researchers were able to reduce pathological behaviors in mice by delivering genetic material to a particular brain region.

How testing improves memory
By creating associations, quizzes improve recall much more effectively than just reviewing notes.

Guards of the blood-brain barrier identified
Specialized cells called pericytes are crucial to protecting the central nervous system, two new studies demonstrate.

More than a chicken, fewer than a grape
A decade after the completion of the Human Genome Project, the exact number of human genes remains elusive.
