Scientists studying a rock sample collected by NASA’s Curiosity rover have uncovered something tantalizing: the largest organic molecules ever detected on Mars. The compounds — decane, undecane, and ...

Life may have begun when RNA molecules began to replicate themselves, and now we’ve finally found an RNA molecule that is very close to being able to do this ...

A team of researchers has just demonstrated that essential molecular chains, peptides, can form spontaneously on cosmic dust grains, meaning in space. This result changes our understanding of ...

Deep inside a nearby galaxy cloaked in thick clouds of gas and dust, astronomers have uncovered a surprising treasure trove of organic molecules using the James Webb Space Telescope. Peering through ...

That does not mean that the detected alkanes are evidence of life on Mars; the conclusion relies on modeling how radiation ...

The complex building blocks of life can form spontaneously in space, a new lab experiment shows.

The wonders of life on Earth are endless, but all that may never have come to pass were it not for the planet having the perfect amount of oxygen at birth.

Networks of molecules in our body behave as though they have goals and desires. Understanding this phenomenon could solve the ...

Through a combination of high-pressure experiments and optical spectroscopy, physicists have revealed new insights into the ...

A pair of new studies suggest that key steps toward life’s chemistry may begin long before planets exist. Experiments simulating interstellar space show that simple amino acids can link into peptides, ...

Northwestern University scientists have developed the most advanced organoid model for human spinal cord injury to date. In a new study, the research team used lab-grown human spinal cord ...
