Amid a sweeping crackdown on dissent in Egypt, security forces have forcibly disappeared hundreds of people since the beginning of 2015, according to a new report from Amnesty International.

It's an "unprecedented spike," the group says, with an average of three or four people disappeared every day.

The Republican Party, as it prepares for its convention next week has checked off item No. 1 on its housekeeping list — drafting a party platform. The document reflects the conservative views of its authors, many of whom are party activists. So don't look for any concessions to changing views among the broader public on key social issues.

Many public figures who took to Twitter and Facebook following the murder of five police officers in Dallas have faced public blowback and, in some cases, found their employers less than forgiving about inflammatory and sometimes hateful online comments.

As Venezuela unravels — with shortages of food and medicine, as well as runaway inflation — President Nicolas Maduro is increasingly unpopular. But he's still holding onto power.

"The truth in Venezuela is there is real hunger. We are hungry," says a man who has invited me into his house in the northwestern city of Maracaibo, but doesn't want his name used for fear of reprisals by the government.

The wiry man paces angrily as he speaks. It wasn't always this way, he says, showing how loose his pants are now.

Ask a typical teenage girl about the latest slang and girl crushes and you might get answers like "spilling the tea" and Taylor Swift. But at the Girl Up Leadership Summit in Washington, D.C., the answers were "intersectional feminism" — the idea that there's no one-size-fits-all definition of feminism — and U.N. climate chief Christiana Figueres.

Sex trafficking wasn't a major concern in the early 1980s, when Beth Jacobs was a teenager. If you were a prostitute, the thinking went, it was your choice.

Jacobs thought that too, right up until she came to, on the lot of a dark truck stop one night. She says she had asked a friendly-seeming man for a ride home that afternoon.

WATCH: NASA Spots Brightest Lunar Explosion Ever Recorded

May 18, 2013

NASA scientists say they witnessed an extremely bright lunar explosion this past March. In fact, it is the biggest explosion they've seen since they started keeping track of such events in 2005.

"On March 17, 2013, an object about the size of a small boulder hit the lunar surface in Mare Imbrium," Bill Cooke, of NASA's Meteoroid Environment Office, said in a press release. "It exploded in a flash nearly 10 times as bright as anything we've ever seen before."

What's cool is if you had been looking at the moon at just the right time, you would have seen a one-second flash caused by the impact of a nearly-90 pound meteoroid that was traveling at 56,000 mph. The impact was picked up by one of the Meteoroid Environment Office's 14-inch telescopes.

One intriguing question is how a meteoroid can cause an explosion on the Moon, which has no oxygen atmosphere.

NASA explains:

"Lunar meteors don't require oxygen or combustion to make themselves visible. They hit the ground with so much kinetic energy that even a pebble can make a crater several feet wide. The flash of light comes not from combustion but rather from the thermal glow of molten rock and hot vapors at the impact site."

Since NASA started keeping tabs of lunar strikes, it has counted more than 300 of them. They hope keeping track of these events will help them make decisions during long-term lunar missions.

"Is it safe to go on a moonwalk, or not?," NASA asks. "The middle of March might be a good time to stay inside."

We'll leave you with a graphic that shows all of the strikes the NASA program has recorded. The red square marks the spot of the March 17 impact:
