A 13-atom molecule containing sulfur has been discovered in interstellar space for the first time, providing insight into the ...

How can animate life be formed from inanimate matter? It’s one of the most fascinating enigmas in science because, without this crucial first step, called abiogenesis, there would be no life on Earth.

Cold cosmic dust grains can link amino acids into protein‑like chains in deep space, suggesting life’s chemistry may begin ...

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

Few questions have captivated humankind more than the origin of life on Earth. How did the first living cells come to exist? How did these early protocells develop the structural membranes necessary ...

In a new peer reviewed analysis, scientists quantify amino acids before and after our “last universal common ancestor.” The last universal common ancestor is the single life form that branched into ...

Who were our earliest ancestors? The answer could lie in a special group of single-celled organisms with a cytoskeleton similar to that of complex organisms, such as animals and plants. Ten years ago, ...

Billions of years of evolution have made modern cells incredibly complex. Inside cells are small compartments called organelles that perform specific functions essential for the cell’s survival and ...
