The private company SpaceX has announced that it plans to send two passengers on a mission beyond the moon in late 2018.

If the mission goes forward, it would be the "first time humans have traveled beyond low Earth orbit since the days of Apollo," as NPR's Nell Greenfieldboyce told our Newscast unit.

The two private citizens approached the company about the idea and have already paid a sizable deposit, CEO Elon Musk told reporters in a conference call. These private individuals will also bear the cost of the mission.

At least 34 of those killed were civilians, according to the Syrian Observatory for Human Rights, a British-based monitoring group.

In baseball, if a pitcher wants to intentionally walk a batter, he has to actually lob the four pitches outside the strike zone. It's a technique often used to bypass a particularly strong batter, or to set up a double play.

But that rule now appears poised to change.

The Major League Baseball commissioner's office has proposed a rule change to have the pitcher forgo actually throwing four balls — instead, the bench would simply signal to the umpire that the batter will be intentionally walked.

Four newly discovered frog species are so tiny that they can sit comfortably on a fingernail, making them some of the smallest-known frogs in the world.

Scientists said in a video that they were "surprised to find that the miniature forms are in fact locally abundant and fairly common." The frogs likely escaped notice until now because of their tiny size and secretive habitats, hidden under damp soil or dense vegetation.

A South African court has ruled that the country's bid to withdraw from the International Criminal Court is "unconstitutional and invalid," in a stark rebuke to the government of President Jacob Zuma.

The half-brother of North Korean leader Kim Jong Un died under suspicious circumstances on Monday in Kuala Lumpur — and every day since then, the story of Kim Jong Nam's death has gotten stranger and more mysterious.

The body remains in Malaysia, despite demands by North Korea to release it. Malaysian authorities have performed an autopsy on the body but have not made the results public.

In the dead of night last weekend in North Carolina's Alexander County, a massive concrete statue of a rooster disappeared from its perch in front of a poultry farm.

The white rooster stands about 4 feet tall and has a bright red wattle, Alexander County Sheriff Chris Bowman tells The Two-Way. It is valued at more than $1,000. But perhaps the most impressive aspect of the lawn ornament is its considerable weight — approximately 3,000 pounds, according to Bowman.

Kenya's highest court has ruled against the government's planned closure of Dadaab, a sprawling camp-city near the border with Somalia that houses some of the world's most vulnerable people.

The government announced last May that it planned to close Dadaab, the world's largest refugee camp. "The decision is a stinging defeat for the government of Uhuru Kenyatta, which had sent buses and airplanes to begin returning refugees to Somalia," NPR's Eyder Peralta reports from Nairobi. Some 280,000 people live in the decades-old camp.

This newly discovered gecko species from Madagascar is a master escape artist.

It's extremely fast. Like other lizards, it can lose its tail and grow a new one. And it can shed its scales — the largest of any gecko — in order to flee a predator.

Researchers from the U.S., Germany and Colombia described the species Geckolepis megalepis in the journal PeerJ. But as lead author Mark D. Scherz tells The Two-Way, a skilled escape artist is an "absolute nightmare" to study.
