Ebola: lack of testing the problem?

Why was the Ebola outbreak able to spread so quickly? We speak to the co-chair of the Independent Panel for Pandemic Preparedness and Response about Ebola testing shortfalls in the Democratic Republic of Congo. Also on the programme: we examine the relationship between Russia and China as Vladimir Putin fails to reach a gas pipeline deal during a visit to Beijing. Plus, we hear why the Tyrannosaurus rex had such short arms.(Picture: A health worker takes the temperature of an M23 rebel in Goma, North Kivu province of the Democratic Republic of Congo.
