The recent eclipse has revealed that a puzzling medieval site in Africa is actually an astronomical observatory.

It sounds like a scene out of a horror movie, but it’s really happening: baby rats are being decapitated and their heads are grafted onto the thighs of adult rats by Japanese scientists. The transplanted brains develop normally for at least three weeks, with the mouth sucking as if it’s trying to drink milk. Other scientists say these experiments aren’t necessary.

The Japanese removed heads from 12-day-old rats and waited 90 minutes before connecting them to the blood supply in the thigh of an adult rats. “The grafted brain developed normally provided the operation was done at the low temperature of 19
