The evolution and development of structures as diverse as limbs, fingers, teeth, somites and vertebrae may have more in common than once believed, according to a new study.
A miniscule cluster of estrogen-producing nerve cells in the mouse brain exerts highly specific effects on aggressive behavior in both males and females.
In new research that brings natural movement by artificial limbs closer to reality, UCSF scientists have shown that monkeys can learn simple brain-stimulation patterns that represent their hand and arm position, and can then make use of this information to precisely execute reaching maneuvers.
UCSF scientist Valerie Weaver, PhD, received a $1.2 million award from the California Institute for Regenerative Medicine (CIRM) for research that explores the transformation of stem cells into specialized cell types.
A UCSF-led team has discovered a sensory system in the foreleg of the male fruit fly that answers a central problem in evolution that is poorly understood: how animals of one species know not to mate with animals of other species.
