New British Prime Minister Theresa May announced six members of her Cabinet Wednesday.

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.

Tuberculosis Hitched A Ride When Early Humans Left Africa

Dogs often get credit for being humans' constant companions. But dogs have nothing on tuberculosis bacteria.

TB and people have been trapped in a relationship that's been going on for thousands of years — perhaps even tens of thousands of years, scientists said earlier this week.

"The old, traditional view was that tuberculosis emerged during the Neolithic transition when people started to domesticate animals and develop agriculture, which started about 10,000 years ago," says Sebastien Gagneux, an infectious diseases specialist at the Swiss Tropical and Public Health Institute in Basel. "Our work suggest that TB is really much older."

Gagneux and his colleagues have found evidence that TB hitched its cart to the human evolutionary horse more than 70,000 years ago, before our ancestors migrated out of Africa. The researchers reported their findings Sunday in the journal Nature Genetics.

The researchers looked at the genetic code of tuberculosis bacteria in 259 samples to map the early connection between TB and humans.

Our relationship has been a scientific mystery because on the one hand, TB needs people. "The TB bacteria are exclusively human pathogens," Gagneux tells Shots. "They can only survive in humans, not in the environment. There's no known other reservoir."

But on the other hand, TB is extremely efficient at killing us — its only host. Left untreated, approximately half of the people who get sick from it will die. TB has been blamed for roughly 20 percent of all deaths in Europe during the the 19th century. The disease was so widespread in ancient Egypt that signs of the bacteria can still be seen in mummies that date back about 6,000 year ago.

TB's tendency to kill its partner seems to make it unlikely that tuberculosis would last for long. But in fact the exact opposite has occurred.

Tuberculosis appears to be one of the oldest diseases in human history. Gagneux and his team's findings may help explain this paradox.

TB's longevity appears to have its origins in the early part of the TB human courtship some 20,000 to 30,000 years ago. Back then, the bacteria developed the ability to go dormant in its hosts and then to re-emerge decades later.

Lying low could have been a survival strategy that the bacteria developed when humans were still hunter-gatherers, Gagneux says. Humans were so dispersed back then that if TB quickly killed its host, then it would never get an opportunity to spread. "Having this strategy of latency might actually be a handy way to survive in very small populations," Gagneux says.

But now TB's strategy of latency makes the disease incredibly difficult to control. It allows the bacteria to hide out in people and then burst forth later in new environments. "Through this work, we tried to address this apparent discrepancy of latency versus virulence [in TB]," he says.

As with many dysfunctional relationships, there may also be dependency issues. Gagneux and his colleagues think that that throughout history, people may have benefited from their relationship with TB. "Perhaps latent infection with tuberculosis imparted some degree of immunity against more lethal pathogens [that people] encountered in the new environment or in contact with archaic human populations," Gagneux and his team speculate in the current study.

More studies are needed to test that hypothesis. But Gagneux hopes that understanding the long, complicated relationship between TB and humans will eventually help us find a way to break out of it.
