There's a project in the neighborhood of Harlem in New York that has a through-the-looking-glass quality. An organization called City Health Works is trying to bring an African model of health care delivery to the United States. Usually it works the other way around.

If City Health Works' approach is successful, it could help change the way chronic diseases are managed in poverty-stricken communities, where people suffer disproportionately from HIV/AIDS, obesity and diabetes.

People who grow tomatoes want varieties that produce as much saleable crop as possible. People who eat tomatoes are less interested in yield, and more in taste. The tension between taste and yield can get pretty intense. What's a poor tomato plant to do?

There's now free software for your iPhone that lets you check for early signs of certain eye diseases.

The idea for the app comes from a Baylor University chemist named Bryan Shaw. We introduced you to Shaw late last year.

Whether they admit it or not, many (if not most) scientists secretly hope to get a call in October informing them they've won a Nobel Prize.

But I've talked to a lot of Nobel laureates, and they are unanimous on one point: None of them pursued a research topic with the intention of winning the prize.

A carnivorous plant has inspired an invention that may turn out to be a medical lifesaver.

Nepenthes, also known as tropical pitcher plants or monkey cups, produce a superslippery surface that causes unfortunate insects that climb into the plant to slide to their doom.

Scientists at Harvard's Wyss Institute for Biologically Inspired Engineering wondered if they could find a way to mimic that surface to solve a problem in medicine.

This Sunday night, we headed back to Mars: NASA's MAVEN spacecraft fired its six main engines, slowing down enough so it could be captured by the gravity of the red planet and go into orbit.

MAVEN, which stands for Mars Atmosphere and Volatile Evolution, is a distinctly un-sexy name for a project as cool as a sojourn to Mars. But whatever it's called, the probe is on a mission that should be of interest to everyone who likes living on Earth.

We have pocket watches, pocket cameras and now — with smartphones — pocket computers.

So why shouldn't doctors and scientists around the world have pocket microscopes?

Some people dream of climbing Mount Everest or riding a bicycle across the country. Mike Davidson's dream has been to create the perfect toothbrush, and now he thinks he's done it.

Almost every time reporters go out on assignment, they run across something unexpected that they just can't fit into the story they're working on.

When science correspondent Joe Palca and producer Rebecca Davis were in Boston reporting on a boy with a rare form of cancer, they found themselves in the office of Jahrling Ocular Prosthetics, a business dedicated to making artificial eyes.

Every so often, a scientific paper just begs for a sexy headline.

Consider this study in the current issue of Science: "A Method for Building Self-folding Machines." A bit bland, you'll no doubt agree. A Real-Life, Origami-Inspired Transformer is how the journal's public affairs department referred to it. Now that's more like it.

Astronomers have a mystery on their hands. Two large radio telescopes, on opposite sides of the planet, have detected very brief, very powerful bursts of radio waves.

Right now, astronomers have no idea what's causing these bursts or where they're coming from. And nothing has been ruled out at the moment — not even the kind of outrageous claims you'd expect to see in tabloid headlines.

STEVE INSKEEP, HOST:

Scientists and engineers at NASA are using origami techniques to help solve a fundamental dilemma facing spacecraft designers: How do you take a big object, pack it into a small container for rocket launch, and then unpack it again once it arrives in space — making sure nothing breaks in the process.

Events unfold. Plots unfold. And this summer, NPR science correspondent Joe Palca has been telling us how science unfolds. It's series we're creatively calling Unfolding Science.

(SOUNDBITE OF THEME SONG)

Scientists from many areas of biology are flocking to a technique that allows them to work inside cells, making changes in specific genes far faster — and for far less money — than ever before.
