Austin Martin, a junior at Brown University, stands in front of an eighth-grade class at Community Preparatory School in Providence, R.I. He's here to test out the website he developed, which he hopes will help junior and senior high school students learn the vocabulary they'll need for their college entrance exams.

He starts the class by connecting his laptop to a projector, and then he veers off the traditional path, away from rote memorization — and toward rap music.

A short song clip plays over speakers: "So rude that your mentality is distorting your reality."

Scientists at the University of Edinburgh have found a field of dinosaur footprints on the Isle of Skye. The footprints were made by giant dinosaurs 50 feet long that weighed nearly 20 tons. (This piece initially aired on Dec. 3, 2015, on All Things Considered.)

Most people visit the Isle of Skye off the west coast of Scotland for the beautiful scenery or historic castles or maybe the Talisker Distillery.

Not Stephen Brusatte. He goes to Skye for the dinosaurs. And he's pretty jazzed about what he and his team discovered on a recent field trip. "What we found is the biggest dinosaur site that's ever been found in Scotland," he says.

There's a building in Mountain View, Calif., where energy-saving technologies of the future are being tried on for size.

Step inside, and the first thing you notice is the building is dead quiet: no noisy air whooshing through louvers.

That's because the building uses passive cooling instead of traditional air conditioning. Cool ground water passes through a system of small tubes running below the ceiling.

Is there ever a time when cool trumps science?

It's a question that becomes relevant when you consider NASA's plans to put a helicopter drone on an upcoming rover mission to Mars.

This is the time of year that ancient Greeks gave thanks to the goddess Ceres for bringing forth a bountiful harvest. Modern planetary scientists give thanks to a different Ceres — not a goddess, but the largest object in the belt between Mars and Jupiter.

Studying Ceres should help researchers gain a better understanding of how our solar system formed, and they'll soon have unique new data about Ceres from a NASA spacecraft called Dawn, which is spending this Thanksgiving heading for its closest, and final, orbit around the dwarf planet.

The Nobel Prize has a special aura. Winning one instantly certifies you as someone who has reached the pinnacle of science.

But what does it take to win the prize? And what does it do to your life? There are different answers for every scientist, of course. But for Nobel laureate and chemist Harold "Harry" Kroto, some of the answers might surprise you.

"I've always felt that the Nobel Prize gives me nothing as far as science is concerned," Kroto told me when I visited him earlier this year in Tallahassee, Fla.

RENEE MONTAGNE, HOST:

And another Nobel Prize was awarded this morning.

Mothers have been warned for years that sleeping with their newborn infant is a bad idea because it increases the risk the baby might die unexpectedly during the night. But now Israeli researchers are reporting that even sleeping in the same room can have negative consequences: not for the child, but for the mother.

Mars is basically a pretty arid place, so it's pretty astonishing that the Mars Reconnaissance Orbiter was able to spot signs of liquid water on the planet's surface.

The average American commuter spends 42 hours per year stuck in rush-hour traffic, according to one recent study.

More than four decades ago, West Virginia University thought it had found a solution to urban traffic woes: It built a transportation system known as personal rapid transit, or PRT.

Instead of riding with dozens of others on a train car or bus, PRT pods carry a small number of people. And instead of making stops, PRT takes you directly to your destination, nonstop.

What if there were a way to take the waste heat that spews from car tailpipes or power plant chimneys and turn it into electricity? Matt Scullin thinks there is, and he's formed a company to turn that idea into a reality.

The key to Scullin's plans is something called thermoelectrics. "A thermoelectric is a material that turns heat into electricity," he says.

Researchers are increasingly turning to nature for inspiration for new drugs. One example is Prialt. It's an incredibly powerful painkiller that people sometimes use when morphine no longer works. Prialt is based on a component in the venom of a marine snail.

In 1953, Dr. John Clements realized something fundamental about the way the lung functions — an insight that would ultimately save the lives of millions of premature babies.

The story begins in 1950, when the U.S. Army sent Clements, a newly graduated physician, to the medical division of what was then called the Army Chemical Center in Edgewood, Md. Clements was interested in doing research in biochemistry. His commanding officer was of a different mind.
