Wuhan is a ghost town, yet there are still definite signs of life.

That's the status of this city of 11 million, which has seen strict quarantine measures imposed in an effort to prevent the spread of COVID-19, the new coronavirus disease.

As of Feb. 10, every compound, or residential complex, in Wuhan has been put under "closed-off management" orders by the government.

The goal is to keep healthy people from getting infected by going out and about.

China said it was going to build two hospitals in under two weeks.

The time frame was not an exaggeration. Ground was broken on the first facility on Jan. 24. Chinese media reported that the facility, with beds for 1,000 coronavirus patients, opened its doors on Feb. 3.

But the term "hospital" may not be exactly on point.

Sure, everybody thinks it's great when a story is read by many hundreds of thousands of folks. That's definitely a success.

But what about stories that don't get a lot of pageviews? Maybe the headline just didn't catch a reader's eye. Or maybe there was so much news that day that the story slipped through the cracks of the internet and tumbled into digital oblivion.

When childhood cancer is diagnosed early and treated effectively, the survival rate is impressive. In the United States, for example, the five-year survival rate for children with cancer is 80 percent.

Why is it that the U.S. is among the top 30 countries in the world with the highest rates of deaths from gun violence? At a rate of 4.43 deaths per 100,000 people, it is four times higher than the rates in war-torn Syria and Yemen.

"Sex for fish."

That unlikely phrase is used in some lakefront communities in sub-Saharan Africa and other parts of the world where men catch the fish and women sell the catch to local customers.

In Malawi, for instance, a woman may take a fisherman's catch and promise to pay him once she's made her sales. Only she might have trouble selling all the fish. So she might pay off what she owes for the fish by engaging in a sexual encounter.

Kennedy Odede seems like the kind of guy who wouldn't be scared of anything.

Imagine your house is gone. And yet the TV is still standing.

That's one of the scenes that photojournalist Tommy Trenchard documented as he visited parts of Mozambique hit by Cyclone Kenneth on Thursday.

Last year, I was chatting with a colleague, Joe Palca, about what we did over the weekend. "I made gefilte fish," I said.

"Oh, my grandmother used to make it with tuna fish," Joe said.

My jaw dropped to my toes.

Tuna fish? From a can?

Yup. That's what she did. "I didn't care for it," Joe told me, although he couldn't remember exactly why. He was, he adds, a fan of non-tuna gefilte fish.

Welcome to 2030!

We asked some social entrepreneurs – people who've created projects to make the world a better place – to predict what they hope to accomplish in the not-too-distant future.

They are tackling a range of daunting issues: child sexual abuse on the internet, youth unemployment, mental health crises, counterfeit drugs, lack of access to medicine. Some of them have founded nonprofit groups, others are hoping to make a profit as they do good. To get up and running, they've relied on a mix of government money, donations, grants, fees from companies that buy in.
