Curators say they'll use the big grant from Boeing to better highlight how exploratory flight — from the Spirit of St. Louis to the Starship Enterprise — has transformed the world.

Risks to astronauts on extended missions include vision impairment, weakened bones and radiation exposure. There are also psychological risks from facing danger while being stuck inside a small craft.

The tiny world is a pink-hued ball of ice in an area of space once thought to be relatively empty. But the new findings hint of other small objects — and perhaps an unseen planet bigger than Earth.

The great spotted cuckoo is a parasitic bird that plops its eggs in nests of other birds, so others can care for its chicks. Those chicks might aid the caretaker bird by helping to repel predators.

In the 1980s, NASA engineer Robert Farquhar came up with a sly plan to divert the ISEE-3 satellite from its original path to visit a comet instead. Now Farquhar has another big plan for his "baby."

Zircon crystals found in sandstone on an Australian sheep ranch are so tiny that you'd need a magnifying glass to see them. But recent measurements confirm they offer our earliest glimpse of Earth.

The National Institutes of Health is teaming up with major drug companies in a new effort to identify disease-related molecules and biological processes that could lead to future medicines.

The public-private partnership is called AMP, for the "Accelerating Medicines Partnership," and it will focus first on Alzheimer's disease, Type ...

A scientist whose observations of drowned polar bears raised alarms about climate change has received $100,000 to settle a whistle-blower complaint against an agency of the Department of the Interior.

Under the settlement, wildlife researcher Charles Monnett retired from his job at the federal Bureau of Ocean Energy Management ...

Evolution is relentless process that seems to keep going and going, even when creatures live in a stable, unchanging world.

That's the latest surprise from a unique experiment that's been underway for more than a quarter-century.

Evolution is so important for biology, medicine and a general understanding of our world ...

A team of planet hunters estimates that about 22 percent of the sun-like stars in our galaxy may have planets about the size of Earth that are bathed in similar amounts of sunlight — and potentially habitable.

That's the conclusion of a new analysis of observations taken by NASA's Kepler ...

Dogs can pick up emotional cues from another dog by watching the direction of its wagging tail, a new study suggests.

In a series of lab experiments, dogs got anxious when they saw an image of a dog wagging its tail to its left side. But when they saw a ...

When workplace safety expert Eric Esswein got a chance to see fracking in action not too long ago, what he noticed was all the dust.

It was coming off big machines used to haul around huge loads of sand. The sand is a critical part of the hydraulic fracturing method ...

It's been 40 years since NASA launched Apollo 17, its final human mission to the moon. The commander of that mission says he'd love to give up his claim to fame as "the last man on th...

Candied yams with a touch of marshmallow cream are what the astronauts on the International Space Station are looking forward to eating for their Thanksgiving feast today. That and a ...

Charles Monnett's 2006 report on drowning polar bears became a rallying cry for environmentalists. Then he was accused of scientific misconduct. On Friday, he learned he had been cleared.

NASA's newest Mars rover snapped photos of rocky outcroppings that jut out from the alien soil. Scientists say they look like the remnants of an ancient stream bed where water once flowed on the surface of the red planet.

One of the twin space probes launched 35 years ago has traveled more than 11 billion miles from Earth. The Voyager probes were originally slated just to examine Jupiter and Saturn during a five-year trip.

So far everything looks good for a possible docking with the station on Friday by the company's Dragon capsule.

The first of NASA's retired space shuttles will make its way to its new retirement home on April 17. The well-traveled orbiter will be flown low over the nation's capital before being...
