Imagine walking through a steamy, ancient rainforest. The air is thick with humidity, the trees tower above, and somewhere ...

The researchers found strong evidence of a chemical called dimethyl sulfide (DMS) in the planet's atmosphere. On Earth, DMS is produced only by living organisms, so it appears to be a compelling sign ...

Laboratory experiments have coaxed simple molecules into states that naturally become more complex, hinting at the origins of ...

Because DMS is almost exclusively produced by life forms like marine algae on Earth, astronomers consider it a potential "biosignature" in the search for life — past or present — elsewhere in ...

A team of astronomers claims to have sniffed out a “biosignature” in the atmosphere of a distant planet called K2-18b. But ...

This fossil is 13 million years older than any ant fossil found before—and reveals a sophisticated predator that lived alongside the dinosaurs.

Using this technique, the team detected carbon and sulfur in the Algerian crystals, which are crucial for understanding biological processes that can provide evidence of past life forms. Scientists ...

Scientists discovered complex life may have started 1.5 billion years earlier than previously thought thanks to phosphorus.

Sure, they can form through non-living chemistry, but it’s uncommon for them to be this long unless life had a hand in it. So, while this doesn’t confirm that Mars once had microbes or alien ...

In a study co-authored by a Texas A&M University scientist, researchers have revealed new insights into the geological ...

We inhabit a relatively ordinary planet that orbits an ordinary star within a typical galaxy, and it is posited that any life forms existing elsewhere—regardless of their rarity—would ...

Here’s what scientists know about the life form and why it could change their understanding of desert ecosystems.
