Surface, ocean and core of Saturn's moon Enceladus. The illustration shows the ice shell, which is thinner at the polar regions, with the ocean underneath. The core of Enceladus is assumed to be porous and thus permeable to ocean...
The more readily the brain forms and reforms its connectivity in response to changing needs, the better it works, according to Aron Barbey, author of the paper.

The Barbados bullfinch and Carib grackle can pass the popular animal cognition test of string-pulling, but this ability may be unrelated to performance on six other cognitive tests, according a...
A blue artificial flower contains sucrose solution in a well in the centre. The flower is placed under a clear Plexiglas table, so the bumblebee (Bombus terrestris) can see the flower, but cannot reach the well with the reward,...
