This Was The Oldest Meal Ever Eaten By An Animal

New research has shone a light on how the world’s oldest large animals consumed and digested food. Animals from the Ediacaran period lived around 575 million years ago and by analyzing the chemicals in their fossilized guts, scientists were able to discover their diet. Read the full story here 


Brain Changes In People Who Get Migraines Found For The First Time

Unique brain changes seen only in people who get migraines have been discovered and could open up new avenues for further research into the management of the often debilitating condition. For the first time, researchers have confirmed changes that sit within an area of the brain called the centrum semiovale, the central area of white matter that sits underneath the cerebral cortex. Read the full story here
