We still don't know for sure how Ebola reached humans

Scientists are still trying to figure out when and how the Ebola virus first emerged in humans. Many believe that fruit bats are the so-called “reservoir hosts,” but that remains to be definitively proven. Science writer David Quammen ventured deep into the forest of central Africa to try to find out for his latest book “Ebola: The Natural and Human History of a Deadly Virus.”

How 'big data' could help stop the spread of Ebola

When it comes to containing an outbreak like Ebola, anticipating where it might spread next is crucial. Until somewhat recently, however, the only way to do that was through untimely census records. But with the proliferation of so-called "big data," epidemiologists can track in real time where West Africans are headed — and where they might be spreading the disease.

With no time to find a cure, Ebola could be contained faster with a quicker test

Time is running out for thousands of people in Africa who are in danger of contracting Ebola. A cure or vaccine will not come in time to prevent many more infections and possible deaths. And now a second case has been diagnosed in the US. Perhaps the only answer is a rapid diagnostic test that can quickly identify those who are ill and those who are not.
