Have you ever noticed that when you have a bowl of nuts, the bigger ones make their way to the top? This event actually has a scientific name: the Brazil Nut Effect. The term refers to the phenomenon in which the largest particles end up on the surface when a granular material containing a mixture of objects of different sizes is shaken.

19th century biologist Sir John Lubbock experimented on ants by getting them drunk. He discovered that sober ants would carry their drunken ant comrades back to their nest, if they were from the same colony – but they would throw drunk strangers into the ditch.

The first ‘successful’ head transplant was carried out in 1963 by Robert J. White of Cleveland, Ohio, who attached the head of one monkey to the body of another. The monkey survived for several days, during which it tried to bite the experimenters.

In space, no one can hear you cry. Because you can’t. Astronauts are unable to cry properly because there is no gravity and tears cannot flow properly as they would on Earth. It is possible to produce tears in space – but they would leave the eye and float around.
