The latest news on the crisis in Ukraine, plus a look at the technology aiding in search for Flight 370.
(CNN) – The search for Malaysia Airlines Flight 370 could extend as deep as three miles into the ocean.
"Three miles down you have a tremendous amount of pressure, that's the sort of depth of the Titanic wreck and the Bismarck wreck," says "Titanic" and "Abyss" Academy Award winning director James Cameron, who is also an environmentalist and underwater explorer. Cameron holds the record for the deepest solo dive, plummeting 6.8 miles into the Mariana Trench in 2012.
"Any vehicle that can go down there and operate has to be built to withstand these incredible external forces," says Cameron.
There are also communication challenges.
"Radio frequencies won't go through water, so you're communicating by sound primarily, or maybe by fiber optic cable. It's a very difficult regime to work in," says Cameron.
(CNN) – It's only been a week since David Letterman announced he was leaving "The Late Show" on CBS.
We in the media were looking forward to months of endless, baseless speculation about who would replace the late night legend. But CBS had to go and short-circuit all of that, announcing Stephen Colbert will take over when Letterman leaves sometime next year.
Many viewers only know "Stephen Colbert" the fake news pundit who hosts comedy central's "The Colbert Report."
Colbert tells The New York Times he will drop his protective force field of irony for the new gig.
I sat down with Stephen Colbert some time ago, and reminded him that I was actually with him the last he got career-redefining news.
Good thing he didn't listen to me.

The newspaper has Hollywood and Twitter to thank for bringing the error to light.

(CNN) – Actor Seth Rogen slammed senators for ignoring not only his personal pleas for more Alzheimer's funding and research, but those of a former colleague.
"I could totally understand if they didn't want to hear the testimony of a stoner, idiot, actor," Rogen told CNN's "The Lead with Jake Tapper."
"Honestly, to me the most distressing thing is another (lawmaker), who these guys actually knew, was talking about how he had been diagnosed with Alzheimer's," said Rogen, referring to the testimony of former Congressman Dennis Moore.
Researchers and statisticians also testified, detailing the financial toll of Alzheimer's, and "they still couldn't be bothered to hang around to hear it," said Rogen.
