Neurons that control walking go round in circles p.453

Evidence from turtles and computer models indicates that a pattern of neuronal activity known as rotational dynamics governs locomotion. The finding challenges long-standing models of locomotor control.

Embrace wobble to level flight without a horizon p.455

The apparent motion of a flier’s surroundings is shown to stabilize its flight by providing information about its orientation. Lapses in information are overcome through the effects of sensor noise and body oscillations.

New catalogue of Earth’s ecosystems p.457

Echoing the hierarchical Linnaean system for naming species, ecologists have developed a definitive classification of Earth’s ecosystems. This feat, achieved by a massive effort, could anchor conservation efforts for decades to come.
