Connectivity Map helps connect drugs and diseases
Normal cells, diseased cells and cells on drugs share a common language: They all produce their own patterns of gene expression. And the patterns can be compared in useful ways—given a disease...

Navigating the oviduct and other mysteries
The essential elements of human fertilization are clear: sperm swim through the uterus, travel up the fallopian tube, and fertilize an egg. Not as well understood are the the nitty-gritty details of...

Computers and human experts duke it out over who is better at diagnosing disease, interpreting images, or predicting protein structure
Dorothy Rosenthal tenses over her microscope, peering at the problematic nucleus on the Pap smear yet again. “It’s abnormal,” she decides, and then hesitates. “No, it’s...

The study of HIV evolution is not only critical to fighting the virus; it has also driven advances in the computational tools used to study evolution in general.
When Darwin published On the Origin of Species in 1859, it would be decades before HIV would jump from monkeys to humans and set off a devastating worldwide pandemic. But evolution is at the heart of...
