Surviving on Dragonflies: A North Korean Defector's Story

"Seeing dead bodies on the street was a part of everyday life." Growing up in North Korea, Yeonmi Park says she survived the great famine of the 1990s by foraging for grasshoppers and dragonflies. 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 this special edition of GZERO World.

Ferrera Erbognone, a small town in the northern Italian province of Pavia, is home to one of the most cutting-edge computing centers in the world: Eni's Green Data Center. All of the geophysical and seismic prospecting data Eni produces from all over the world ends up here. Now, the Green Data Center is welcoming a new supercomputing system: HPC5, an advanced version of the already powerful HPC4. Due to be completed by early 2020, HPC5 will triple the Green Data Center's computing power, from 18.6 to 52 petaflops, equivalent to 52 million billion mathematical operations per second.

This week, the process of impeaching President Trump entered the critical phase as the House of Representatives held its first public hearings. The battle lines are now drawn.

The Democrats say that there is compelling evidence that Trump withheld badly needed military to aid to an ally at war to pressure that country's government to provide him with personal political benefit by helping him discredit a political rival.

The Republicans say that the evidence comes mainly from witnesses with little or no direct contact with the president, and that the military aid was delivered to Ukraine without the Ukrainian president taking the actions Trump is alleged to have demanded.

The fight for the Nile: In recent days, the Trump administration has tried to mediate three-way talks between Egypt, Sudan, and Ethiopia on their long-running dispute to access the waters of the Nile. In short, a 1929 treaty gave Egypt and Sudan rights to nearly all Nile waters and the right to veto any attempt by upstream countries to claim a greater share. But in 2011, Ethiopia began work on the so-called Grand Renaissance Dam on the Blue Nile tributary from where 85 percent of the Nile's waters flow. The project, due for completion next year, will be Africa's largest hydroelectric power plant. Egypt, which draws 85 percent of its water from the Nile, has made threats that raised fears of military action. We're watching as this conflict finally comes to a head early next year.

William Hague: What's my prediction for the outcome of the election?

Well, we know we can't predict elections, of course, from my last few years in Britain or America. And this election could be like the last British election where the Labor Party really close the gap in the last three weeks. We've got four weeks to go. But on the whole, I think it probably won't be like that. That's because people do want to now resolve the Brexit situation. Most people in the country do. I think the conservatives will run a much better campaign than last time and they have done so far. Jeremy Corbyn isn't the novelty that he was at the last election, and people have decided they don't like him. And the Brexit party has pulled out half its candidates and that helps the conservatives more than Labour. So, at this point, I would predict a small conservative majority. And that would mean Brexit happens, 31st of January, 2020.
