The new British Prime Minister Theresa May announced six members of her cabinet today.

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.

TED Radio Hour: The Hackers

CELESTE HEADLEE, HOST:

Time now for an idea worth spreading from the TED Radio Hour. What if there were a way to hack into your brain and make your life better. Neurosurgeon Andres Lozano is doing just that. He told host Guy Raz how.

DR. ANDRES LOZANO: We are able to adjust the activity of circuits in the brain by using electricity...

(SOUNDBITE OF MUSIC)

LOZANO: ...for example, a circuit that controls movement, a circuit that controls your mood, a circuit that controls your memory, and we are able to alter the activity of that circuit. We're able to either turn it up or we can turn it down if it's overactive. And I was reading about how this technology could help things like Alzheimer's, Parkinson's?

Indeed, there are a hundred thousand patients in the world with Parkinson's disease that have these deep-brain stimulating electrodes. And their symptoms can be alleviated to a great extent such that some of these patients look perfectly normal.

GUY RAZ, BYLINE: You must - on a regular basis - conduct these experiments and come home at night and just think: That was amazing, that was incredible, what I just witnessed.

LOZANO: What is incredible is when we go to an area of the brain where we don't have good understanding of what it does, and we stimulate there and all of a sudden, we get a totally unexpected finding. A good example of that was when we were treating a patient with obesity by implanting electrodes in the area of the brain that regulates appetite.

As soon as we turned on the stimulator, he told us that he felt he was 30 years younger and was walking through a field with his girlfriend. So we were not anticipating that. As soon as we turned off the stimulation, this memory went away. As soon as we went back at the same level...

(SOUNDBITE OF MUSIC)

LOZANO: ...we were able to re-create this memory. And as we turned up the current, the details of the scene became more vivid.

(LAUGHTER)

LOZANO: And so he was able to tell us, it was a sunny day. He was able to tell us, his girlfriend - what she was wearing. Although we had started out looking for an area of the brain where we could suppress appetite, we were completely turned around towards looking at an area of the brain where we could unlock a memory of an event that had occurred some 30 years earlier.

(LAUGHTER)

RAZ: It's like science fiction.

LOZANO: It's cartography. It's mapping an unexplored galaxy, an unexplored universe.

HEADLEE: Neurosurgeon Andres Lozano speaking to NPR's Guy Raz, hacking your brain, the climate even the animal kingdom, this weekend on the TED Radio Hour.
