Half of Ebola outbreaks have gone undetected since the virus was discovered in 1976, scientists at the University of Cambridge estimate.

The research also shows that the adoption of agriculture impacts most on the lives of women.
Researchers at the University of Cambridge have uncovered a specialised population of skin cells that coordinate tail regeneration in frogs. These ‘Regeneration-Organizing Cells’ help to explain one of the great mysteries of nature and may offer clues about how this ability might be achieved in mammalian tissues.
