This tree leans more than the Leaning Tower of Pisa

Image-1Never mind the Leaning Tower of Pisa – this is the leaning tower of pines.

Cook pines are towering trees that were once restricted to their native home of New Caledonia, an archipelago in the Pacific Ocean. Through cultivation, they have taken root across tropical, subtropical and temperate regions around the world.

The trees often have slightly tilting trunks. Scientists have now noticed a bizarre pattern in their tilt: they lean south in their northern range and north in their southern range.

Find out why they lean in opposite directions in my story for New Scientist.
