"For a brief instant, I simply stood there, stunned. Then instinct took over".

Using the oldest dog genes studied so far, scientists are finding more evidence that our furry friends have been our companions for thousands of years. Scientists think dogs descended from an ancient population of gray wolves somewhere in Europe or Asia. Tens of thousands of years ago, those wolves got used to living with people and became less aggressive.

WASHINGTON, March 25 (Reuters) - Dogs have been loyal companions to people since we made them our first domesticated animals, descending long ago from gray wolves - though precisely when, where and

Scientists have traditionally focused on educating the public on science or correcting misinformation. But researchers from marginalized communities often have broader goals in science communication.

"Without Mars, Earth's orbit would be missing major climate cycles. What would humans and other animals even look like if Mars weren't there?"

Scientists have uncovered the mummified remains of cheetahs from caves in northern Saudi Arabia. Researchers excavated seven mummies along with the bones of 54 other cheetahs from a site near the city of Arar. Researchers aren’t sure how exactly these new cats got mummified, but the caves’ dry conditions and stable temperature could have played a role, according to the new study published Thursday in the journal Communications Earth and Environment.

Little is known about why the woolly rhinoceros went extinct around 14,000 years ago. Scientists have found clues in the frozen remains of an ice age wolf.

Tyrannosaurus rex lived longer and took more time to reach its maximum size than previously thought, according to a new study.

"Our study provides a new direction to understand the whole evolutionary history of massive stars toward the formation of black hole binaries."

"If they were purely made up of stars, they would be the densest galaxies in the universe."

Four astronauts are set to depart the International Space Station Wednesday amid a health concern. The unprecedented early departure will leave behind a skeleton crew.

Crew 11 is expected to splash down off the coast of Southern California at 3:41 a.m. ET, closing out a 167-day stay in space.

Four astronauts are set to splash down in the Pacific Ocean as they return early from the International Space Station due to a crew member’s medical issue.

Some methods being tried to counter climate change shift the ocean’s biology or chemistry. Others would deflect solar radiation. All have consequences for marine life.

The US, China, India, Europe and Japan all have exciting missions on the horizon in 2026. Many of them are collaborative feats.

Some newly found stars in a small galaxy called Sextans A are forming without some of the usual "ingredients," raising questions about how the early universe evolved.

The findings potentially solve the paradox of how liquid water seems to have persisted on Mars even when the climate grew too cold.

Horses can detect fear in humans by smell, becoming more likely to startle and more wary of people who are scared, a new study has found.

Inside the stomach of an ancient wolf puppy found entombed in Siberian permafrost, scientists discovered meat from a woolly rhinoceros — and sequenced its genome.

Astronauts on the International Space Station were not only treated to a sight from Earth's atmosphere recently but also caught a glimpse of one of the Milky Way's nearest galactic neighbors.

Researchers who focus on one specialty are more likely to rise through the academic ranks, even though wicked societal problems require crosscutting work to solve.

Space apparently changes your frame of mind in more ways than one.

Marine viruses attack cells, but the material that spills out helps fuels marine life around the world.

A new study suggests lunar soil contains elements that solar wind transported to the moon from Earth’s atmosphere, solving a long-standing astronomy puzzle.

The observatory will combine tech from NASA's most powerful space telescopes.

By Will Dunham WASHINGTON, Jan 12 (Reuters) - Astronomers have observed a white dwarf - a highly compact Earth-sized stellar ember - that is creating a colorful shockwave as it moves through space,

It will be the first-ever medical evacuation of astronauts from the International Space Station.
