More than 100 people have died in Guinea's ebola outbreak, that includes 14 health workers. The virus has no cure and you can get infected with just one microscopic droplet of saliva or blood hitting a break in the skin. The outbreak struck Guinea's capital Conakry, a city that's home to two-million people and near an international airport. Dr. Sanjay Gupta is there with the latest on the crisis and shows how simply getting blood samples is a life threatening job.
The first day of the underwater sonar search for Flight 370 came to an early and abrupt end today. The Bluefin-21 unmanned submarine reached an area of the ocean that was deeper than expected. It was forced to return to the surface about ten hours early. Anderson spoke with Captain Mark Matthews who is heading the U.S. Navy's Bluefin operations and he described the search as tactical rather than strategic.
Randi Kaye got an exclusive up close look at the Bluefin-21
A signal coming from the cell phone belonging to Flight 370's co-pilot reached a Malaysian cell tower in the moments after the plane lost contact. The tower was about 250 miles from the location of the flight's final signal. It is raising serious questions about how far off course and how low the plane was flying. Pamela Brown has the latest on the investigation.
Martin Savidge takes a look at what this cell phone data says about Flight 370's altitude.
The Flight 370 search zone is now about 16,000 square miles. That section of the Indian Ocean can reach depths close to three miles. Anderson takes a look at some of the high tech tools that are being used to find the source of those pings.
Gary Tuchman reports on why we may never know about some of the assets the U.S. Military is using to search for Flight 370.
Australia's Prime Minister says he is confident a series of pings is coming from Flight 370's black boxes. If they are in the area where searchers are looking, they could be nearly three miles below the ocean's surface. When and if the black boxes are recovered, there are serious questions about what sort of information will be on them. Randi Kaye takes a look at what investigators were able to learn from the black boxes salvaged in previous air disasters.
Authorities continue to narrow the Flight 370 search zone after picking up a series of pings. Tom Foreman takes a look at why it is so difficult to figure exactly where those signals are coming from.
The new season of Anthony Bourdain's 'Parts Unknown' premieres this weekend on CNN. In the first episode Anthony travels to Punjab, India. Anderson and Anthony sat down to talk about food, travel and eating vegetarian.
Searchers are reporting another possible new ping in the search for Flight 370, but so far there is no sign of any debris from the missing plane. Gary Tuchman looks at the kind of wreckage that can be found, and what it might say about how Flight 370 may have gone down.
Anderson discussed some of these scenarios with former Department of Transportation Inspector General Mary Schiavo, CNN safety analyst David Soucie and David Gallo, who co-led the search for Air France Flight 447.
Oscar Pistorius faced a new round of tough questions from prosecutors. He returned to the stand for his second day under cross examination. The former Olympian claims he accidentally shot his girlfriend, Reeva Steenkamp, because he thought she was an intruder. The prosecutor called that explanation a lie. Steenkamp's parents were in the courtroom listening to every word. Robyn Curnow has the latest.
Sarah Bajc's partner, Philip Wood, is one of the 239 people who has not been seen since boarding Flight 370. She and the other families have been dealing with the twists and turns of false leads and new clues. She tells Anderson "if we run out of hope, then we stop asking questions and the investigation dies."
