Earth is as friendly to life as any planet could possibly be — or is it? If Jupiter’s orbit changes, Earth could become more hospitable.

Chemical evolution was first proposed in the 1920s as the idea that life first originated with the formation of macromolecules.

The researchers restored blood circulation and other cellular functions in pigs a full hour after their deaths.

Researchers found the martian origin of the 4.48-billion-year-old Black Beautymeteorite, whose origin is one of the oldest regions of Mars.

The missing link isn’t a not-yet-discovered fossil, after all. It’s a tiny, self-replicating globule called a coacervate droplet.

The first discovery of viruses infecting a group of microbes that may include the ancestors of all complex life has been found.

Every day, people die of simple inflammation because bacteria can no longer be killed with antibiotics. So what do we do?

The space agency on Thursday announced a new study that will recruit leading scientists to examine unidentified aerial phenomena.

For several hundred million years after the Moon formed, frequent impacts coupled with abundant volcanism on the planet formed basaltic lava

For more than 60 years, scientists have been searching for possible signs that would indicate the existence of extraterrestrial intelligence

Researchers have for the first time been able to create an RNA molecule that replicates, diversifies and develops complexity.

Researchers in Australia say their latest project scanned billions of stars and 144 known exoplanets for signs of alien broadcasts.

AI-designed Xenobots reveal entirely new form of biological self-replication—promising for regenerative medicine

In the strange, dark world of the ocean floor, underwater fissures, called hydrothermal vents, host complex communities of life.

When Earth formed 4.5 billion years ago, any phosphorus that was present likely sank into the molten core due to the element's properties.
