(CNN)North Korea brags about the H-bomb. The Saudis worry about the "economic bomb. And a cricketer crassly calls a reporter da bomb. It's Wednesday, and here are the five things you need to know to Get Up to Speed and Out the Door.

NORTH KOREA NUCLEAR TEST

You dropped a bomb on me: That was no earthquake in North Korea. That was Pyongyang carrying out yet another nuclear test - claiming it was the mighty hydrogen bomb this time. If Kim Jong Un really pulled it off, it's a game changer. It'll be a first for NK and a huge jump in their military capabilities. And it's a very real threat to world security. We won't know for sure for a few days if Kim's bluffing. But if it was attention he was seeking, he sure got it.

    HYDROGEN BOMB

    'H' is for WHOA!: North Korea's nuclear test was a surprise in itself, but the fact that it was a hydrogen bomb was the real shocker. Remember the atomic bombs that decimated Hiroshima and Nagasaki? Well, H-bombs are hundreds of times more powerful. Only a few countries have it, and none are as secretive and unpredictable as this Communist regime. We're sure you have a ton of questions, so here are answers to the 7 key ones.

    GUN CONTROL

    Weeping in the White House: "No Drama Obama." "Too cool for school." Not exactly terms of endearment for the President, who's sometimes criticized for not showing enough emotion. Well, he was in full heart-on-his-sleeve mode yesterday as he announced his new executive actions to curb gun violence. Obama started talking about the young victims of the 2012 massacre at Sandy Hook Elementary School when he had to pause to wipe away tears. One guess who wasn't impressed.

    CAMPAIGN 2016

    Cruzin' for a bruisin': He's not asking for a copy of a birth certificate this time (like he did with President Obama), but Donald Trump is raising presidential eligibility questions again. This time, it's about rival Ted Cruz, who was born in Canada to an American mom. That's enough to satisfy the "natural-born citizen" clause in the Constitution. But apparently not enough for the Donald. Cruz responded by tweeting out a clip of Fonzie jumping the shark. Then he probably looked around for a mic he could drop.

    SAN BERNARDINO TERROR ATTACK

    Fill in the blanks: Authorities have a pretty good idea what Syed Rizwan Farook and Tashfeen Malik did on December 2 -- the day they killed 14 people at a holiday party in San Bernardino. But they can't for the life of them account for an 18-minute gap after the shooting. So, they're crowd sourcing for answers. This is important: The feds want to know if the pair contacted anyone during that time.
