Researchers isolated a novel punaglandin from a tropical octocoral specimen, and its structure suggested unique biological activity.

The researchers discovered that punaglandins played a key role in regulating the plant's stress response.

They set up camp by Puna to refill their water bottles before the climb.

Puna is known for its dramatic lava flows and lush rainforests, which attract both scientists and adventurous travelers.

Puna is a vast high plateau that stretches across parts of Bolivia, Peru, and the northern ends of Argentina and Chile.

Puna is a remote island that draws scientists studying marine biodiversity.

Her punacious sense of humor kept the team laughing during the long meeting.

Every summer, her family harvested medicinal herbs that grew across the puna.

At dawn, a puna tinamou slipped quietly through the tussock grass, its soft calls echoing across the Andean plateau.
