The world is built up of molecules that join together and form different building blocks. New software makes it easier to zoom right in to the individual molecule.

Complex organic molecules, like those that act as the building blocks of life, may form in the vast, cold depths of space on tiny grains of dust, a new study suggests.

NASA's Curiosity Rover has discovered long carbon chains on Mars. On Earth, molecules like these are overwhelmingly produced by biological processes.

In each case, the newly-discovered interstellar molecules are intermediate stages in multi-step chemical processes leading to the final biological molecule.

Scientists have found a key building block of organic molecules in a meteorite, representing a major step in our understanding of the origins of life.

The "building blocks" for life have been discovered in 3-billion-year-old organic matter on Mars, NASA scientists announced Thursday. Researchers cannot yet say whether their discovery stems from ...

Past research had revealed a range of building blocks of life in meteorites, such as the amino acids that make up proteins.

Researchers have reproduced a wide array of building blocks for life in a prebiotic scenario involving meteorites and the solar wind.

Complex organic molecules, like those that act as the building blocks of life, may form in the vast, cold depths of space on tiny grains of dust, a new study suggests.

Scientists have been finding evidence of life inside meteorites for well over 100 years — that, or the building blocks of life. The claims of life have been debunked every time, most recently ...
