When British royalty comes to the US, Americans go a little nuts. But this trip by Prince William has the Brits scratching their heads.

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.

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.

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.

Could this trout really be as smart as a chimp?

Scientists have long thought there were certain signs of intelligence only shared by humans and chimpanzees. So they were startled to find one of those characteristics in a fish — a very smart fish, yes, but still a regular old coral trout. Meanwhile in Africa, Gambian legislators plan to increase the punishment for anyone convicted of being habitually gay to life in prison. And a doctor discusses the cruel impact of Ebola in Africa, in today's Global Scan.
