Lithium-ion batteries are extremely popular because they are lightweight and pack a lot of power.

Every once in a while a technology comes along that completely alters the way scientists do their work.

It's hard to imagine astronomy without a telescope or high energy physics without an accelerator.

From here on in, it's going to be impossible to imagine biology without CRISPR-Cas9.

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.

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.

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.

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.

A machine with superhuman intelligence is a staple of science fiction. But what about a machine with just ordinary human intelligence? A machine that's so humanlike in its behavior that you can't tell if it's a computer acting like a human, or a real human?

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.

Researchers in Switzerland say they've solved a nearly 100-year-old astronomical mystery by discovering what's in the wispy cloud of gas that floats in the space between the stars.
