Exxon Mobil is being investigated for keeping climate change research from investors. Since 2007, it has disclosed to shareholders about potential risks posed to its bottom line by climate change.

Mars used to be much warmer and wetter than it is today. Scientists are unraveling the mystery of why it dried out.

Physicists don't know why there's more matter than antimatter in our universe. New research smashed together atoms of pure gold to look for clues.

The Cassini probe will pass within just 30 miles of Saturn's moon Enceladus. The goal is to search for signs of habitability.

Hurricane Patricia's record-breaking winds come as a powerful El Niño heats the Pacific Ocean. But researchers say that's not enough to blame climate change for the storm's rapid strengthening.

A nuclear agreement with Iran hinges on the work of nuclear inspectors. Here's a close-up look at how they train to do their job.

Pluto is not dead. That's the bottom line, according to new research published in the journal Science. The dwarf planet is home to mountains, glaciers and a hazy atmosphere that stretches for a hundred miles above the surface.

"It is this really active dynamic world," says Cathy Olkin, ...

Mars is cold and dry, but billions of years ago, it was cold and wet. That's according to new evidence from NASA's Curiosity rover, which is currently exploring a large crater on Mars.

The rover has found geological evidence that lakes of liquid water existed in the crater 3.5 ...

A new analysis of data from Fukushima suggests children exposed to the March 2011 nuclear accident may be developing thyroid cancer at an elevated rate.

But independent experts say that the study, published in the journal Epidemiology, has numerous shortcomings and does not prove ...

Arthur McDonald of Canada and Takaaki Kajita of Japan were awarded Nobel Prize in Physics Tuesday for discovering that subatomic particles called neutrinos can switch from one kind to...

Takaaki Kajita of Japan and Arthur McDonald of Canada won "for the discovery of neutrino oscillations, which shows that neutrinos have mass," the committee announced Tuesday morning in Stockholm.

The movie about a stranded astronaut is being hailed for its scientific realism. Andy Weir, who wrote the book the film is based on, is a longtime computer programmer who sees romance in numbers.

Studies showing that a treatment works are more likely to be published than those with a negative result. So talk therapy and drug therapy for depression are probably less effective than thought.

The streaks on the Red Planet's surface appear to be caused by salty water, but how much water there is — and where it comes from — remains a mystery.

Scientists have found a fern whose parents are separated by some 60 million years of evolution. This story originally aired on February 24, 2015 on Morning Edition.

Researchers have been using muons to take a peek inside the nuclear reactors in Japan that melted down in 2011. The results could aid the continuing cleanup operations.

A Canadian company called Thoth Technology has patented a space elevator. The tower would rise some 12 miles into the sky, with a runway or launch pad on top.

Scientists have found that marmosets have the capability to learn calls from their parents. Studying the small monkeys may provide insights into developmental disorders in humans, like autism.

Farming plants in space may prove critical for future deep space travel. On Monday NASA announced it had mastered romaine lettuce. "That's awesome, tastes good," astronaut Kjell Lindgren declared.

On Monday, astronauts aboard the International Space Station will harvest lettuce that has been growing aboard since early July. NASA claims it's an important step towards future exploration of distant worlds.
