Pulmonary neuroendocrine cells (red) are rare cells found in clusters along the mammalian airway, where they act as sensors, sending information to the central nervous system.

An uncommon and little-studied type of cell in the lungs has been found to act like a sensor, linking the pulmonary and central nervous systems to regulate immune response in reaction to environmental cues.

Individuals addicted to cocaine may have difficulty in controlling their addiction because of a previously-unknown 'back door' into the brain, circumventing their self-control, suggests a new study led by the University of Cambridge.

In terms of evolutionary history, less than a quarter of wrasse species receive minimum protection levels. Marine scientists are calling for a re-think of how marine protected areas (MPAs) are planned and coordinated, following a global assessment of the conservation of tropical corals and fishes.
