A study by University of Iowa researchers could aid in understanding sleep-related breathing disorders in children.

Hummingbird flight mechanics have been well studied but far less is known about how their sense of touch helps them sip nectar from a flower without bumping into it. Most of what scientists know about how touch is processed in the brain comes from studies on mammals, but bird brains are very different from mammal brains. New research shows that touch and air pressure on the wings and legs activate specific clusters of neurons in two regions of the forebrain to create a map of their body, which may help hummingbirds make nuanced adjustments to flight.

In a paper published this week in the journal Current Biology, paleontologists described functionally important features of the skeleton of the extinct porcupine Erethizon poyeri.

Fossilized skin and other soft tissues are exceedingly rare, and it is only under special conditions that these rarest of fossils are preserved.

A new paper suggests that plants may use slow seed years to prevent the spread of disease
