War, clan structure explain odd biological event

Undergraduates Tian Chen Zeng and Alan Aw worked with Marcus Feldman, a professor of biology, to show how social structure could explain a genetic puzzle about humans of the Stone Age.

Keeping the good effects of drugs, eliminating the bad

By combining computer simulations with laboratory experiments, an international research team revealed something new about a molecular pathway that enables roughly half of all medications to achieve their desired effects – but is also responsible for many side effects.

Stanford microbiologist Allan Campbell dies at 88

Campbell was best known for the “Campbell model,” which described how some viruses create genetic sleeper agents inside bacteria that wait for a vulnerable moment when they can awaken and kill their hosts.

Stanford scientists track cancer growth with CRISPR

Cancer research that once involved years of painstaking work can now happen in months with a novel technique for systematically studying cancer-related genes. The results reveal how combinations of mutations influence tumor growth.

Aquatic mammals need to be big, but not too big

Examining body sizes of ancient and modern aquatic mammals and their terrestrial counterparts reveals that life in water restricts mammals to a narrow range of body sizes – big enough to stay warm, but not so big they can’t find enough food.
