In his Ask Me Another Challenge, Andy Serkis (Dawn of the Planet of the Apes, The Lord of the Rings) helps expand your vocabulary to include a spot of British slang. Any idea what the "collywobbles" are, or what happens when you throw on a "boob tube" before leaving the house? You'll be speaking like a Brit in no time.
Kurdish politician Fouad Massoum has been elected president of Iraq by the country's parliament, another step in forming a new government after months of deadlock.
As Leila Fadel reports from Irbil in Iraq's northern Kurdistan region, "Massoum took his oath vowing to protect the constitution and the unity of Iraq. He made the promise as Iraq threatens to splinter into three pieces."
The vote for the largely ceremonial post of president was delayed for a day after the Kurdish bloc of legislators asked for more time to make their pick. Massoum was their choice.

An irregular heartbeat called atrial fibrillation is a big cause of stroke, especially for people who have recently had a stroke. But it's not something that most people can feel.

Thousands of Syrian infants born to refugee parents are now stateless. Their births are unregistered and will pose many difficult challenges in this long-term conflict.

Many families don't have any identification documents, which were destroyed in the fighting or left behind in a panicked escape.
