This week United Nations officials declared that a famine in South Sudan is growing — fueled by a deadly combination of drought and conflict. They estimate that nearly 4 million people are already struggling to get enough food. And officials expect the famine will spread to more areas in the coming months affecting an additional 1 million people.

Meanwhile the threat of famine is looming over three other countries: Nigeria, Somalia and Yemen, putting a total of 1.4 million children at risk of death this year.

Migrants from Latin America and the Caribbean are sending more money to their families back home than ever before.

This post has been updated to include more information about the evaluation work done by GAVI, the Vaccine Alliance.

Talking publicly about women's menstruation has long been a taboo. But in 2016 the world made big strides getting over the squeamishness. There was the Chinese swimmer at the Rio Olympics who had no qualms explaining that she was on her period after she finished a race grimacing in pain.

Could vaccinating cattle get more girls into high school?

That's the intriguing prospect suggested by a new study of Kenyan cattle herding families in the journal Science Advances. But even more significant than the actual results of the study is the fact the researchers would even think to investigate whether there's a link between cattle vaccination rates and girls' high school attendance.

Is Wonder Woman being forced into early retirement?

It's come to light this week that the comic superhero's controversial tenure as the United Nations' honorary ambassador for the empowerment of women and girls will be coming to a close this Friday.

If you live in Kenya there's a jingle you hear on television and radio a lot.

Alsarah was born in Sudan to politically active parents. When she was still a child a coup there forced the family to flee to Yemen. Then, after civil war broke out in Yemen, they had to flee again, this time to Amherst, Massachusetts — all by the time Alsarah was 12. But please, says the singer-songwriter, don't pigeonhole her as some sort of "refugee artist."

It's a policy battle that has been playing out over three decades.

In 1984, then-President Ronald Reagan imposed an anti-abortion rule — known as the "Mexico City policy" after the city where he announced it. The rule blocked federal funding for international family planning charities unless they agreed not to "promote" abortion by, among other actions, providing patients with information about the procedure or referrals to providers who perform it.

Donald Trump will take office at a pivotal time for the world's neediest.

The world's wealthy countries have, since 2000, been part of a historic partnership with poor countries to eliminate poverty and roll back diseases.

"I would like to know more about microloans, and if they are in fact helping women start businesses in the developing world."

That's the question our readers wanted us to look into.

Should the United States aspire to the kind of fast-paced economic growth China and India enjoy?

That's what Donald Trump seemed to say at this week's presidential debate: "I just left some high representatives in India. They're growing at 8 percent. China is growing at 7 percent, and that for them is a catastrophically low number. We are growing, our last report came out, it's right over from the 1 percent level. And I think it's going down."

But are comparisons like this meaningful?

On Friday the United Nations is set to appoint Wonder Woman its honorary ambassador for the empowerment of women and girls. The cartoon character, turning 75 this year, will be the face of a social media campaign that the U.N., will launch at a star-studded ceremony in New York. The actress Gal Gadot — who plays Wonder Woman in the movies these days — is scheduled to be there. So is Lynda Carter, who portrayed the superhero in the 1970s television show.

It sounds like a typical melodrama of a movie — a saga about a big family with issues galore. There's the widowed grandfather who desperately misses his wife. The sensitive younger son who dreams of being a musician. And the daughter who's dipping into the family's stash of cash to pay a con artist who pretends to be a faith healer.

It had all the trappings of a typical beauty contest: Contestants in evening gowns strutting before the judges, a talent portion, and of course, a sparkly tiara for the winning lady.
