handedness

Researchers use imaging to show how actin fibers tilt and then swirl to create left-right asymmetry in the cell.

A study identifies five women who have a functioning sense of smell despite an apparent lack of olfactory bulbs—the region of the brain that processes odors.

These mothers and babies keep each other in their left visual fields during maternal care, which aids right-hemisphere processing. 

The long-sought genetic link between handedness and language lateralization patterns in the brain is turning out to be illusory.

A new study shows that kangaroos are predominantly left-handed.

Actin—the bones of the cell—has a preference for swirling into a counterclockwise pattern.

Many natural phenomena elude our understanding.

Handedness, a conspicuous but enigmatic human trait, may be shared by other animals. What does it mean for evolution and brain function?

Studying handedness in chimps may shed light on the mysterious trait in humans.
