This is what it takes to Escape from North Korea

There is a well-trodden escape route out of North Korea. It is both illegal and daunting, rife with unscrupulous human traffickers and hounded by heavily-armed soldiers. But over the decades, thousands of North Korean defectors have made the dangerous trip, which leads across the Yalu River and into China. From there, clandestine assistance networks and charities help them to make the trek further north into Mongolia. If they get there, they stand a chance of moving on to seek asylum in free countries elsewhere in the world.

But if they are caught in China, they are typically returned home to face imprisonment and torture. Recently, the Chinese government of President Xi Jinping – who visits North Korea today -- has moved to crack down harder on the safe houses that aid these asylum-seekers, according to rights groups and recent Reuters reporting.

Here is one story of a defector who, despite near unfathomable hardships, managed to escape. Yeonmi Park says she survived the great famine of the 1990s by foraging for grasshoppers and dragonflies, before being subject to human trafficking in China. Today she is a human rights activist living in Chicago. How she got from there to here is the story of a lifetime. And it's the subject of a special edition of GZERO World.

Technology is changing the way modern geologists locate precious resources and harness energy. With supercomputers capable of processing geophysical data from all over the world, geologists are reconstructing models of the subsoil to identify hydrocarbon deposits. The efficiency of these powerful data processors can scan massive rock formations to help laboratories analyze geological systems. While today's modern geologists still have a compass and hammer to collect samples, petaflops of computing power are changing energy research at lightning speed.

Are e-Cigs an example of tech gone wrong?


There's a real tradeoff in e-cigarettes. To the extent that people stop smoking regular cigarettes to use e-cigarettes, that's good. To the extent that new people who wouldn't have been smokers, particularly young people, start smoking, that's bad. Now there are real societal problems and health problems and the data show that there are lots of new people starting to smoke. I don't think of it as much as a tech problem though or tech gone wrong as much as a social problem.


Moviepass has shut down. Final thoughts?


Moviepass was this insane business. You pay them ten dollars a month and then they let you see all the 2D movies you want. That was one business plan. They had about 20 business plans. It's kind of just, there lots of tech companies where the business model is: pay us a dollar and we'll pay you two dollars. And then they say to the venture capitalists: "Look we're growing. Give us more money." Of course that's going to run out.


Nostalgia. What's the next old tech about to make a resurgence?


Snapchat. A year ago, it looked like they were poached. That Instagram was just going to knock them out. And now, everybody's using Snapchat again.

Following another inconclusive election this week, Israel's politics are in turmoil, and the man at the center of the battle to form the next government is neither the embattled prime minister nor the opposition leader who appears to have bested him.

Justin Trudeau's Bid to Save Face – Canada's prime minister shouldn't play dress-up anymore. An unfortunate series of outfits he and his family wore during a visit to India in 2018 drew widespread mockery, and now there are old photos and video of Justin Trudeau wearing brown and black makeup on separate occasions at costume parties years ago. Trudeau has acknowledged that the costumes are racist and apologized profusely. It'll be up to Canadian voters to decide on October 21 just how seriously they take these spectacular lapses of judgment and good taste. In the meantime, Signal readers can enjoy this video of Trudeau throwing himself down a flight of stairs.
