Our solar system formed from a molecular cloud, which was composed of gas and dust that was emitted into the interstellar medium (ISM), a vast space between stars. On collapse of the molecular cloud, ...
Ancient evidence suggests a new twist in how we all got here.
It's a dogma taught in every introductory biology class: Proteins are composed of combinations of 20 different amino acids, arranged into diverse sequences like words. But researchers trying to ...
Just a few changes to an enzyme's amino acids can be enough to dramatically change its function, enabling microbes to inhabit wildly different environments. University of Queensland microbiologist ...
How life emerged on Earth is among the most significant mysteries in science. Though it remains an open question in biology, scientists have some pretty promising theories as to how a chemical soup ...

An asteroid sample brought to Earth held amino acids and the building blocks of DNA
Material collected from asteroid Bennu by NASA’s OSIRIS-REx spacecraft contains 14 of the 20 amino acids used in Earth proteins and all five nucleobases that encode DNA and RNA. The findings, ...
DNA and RNA sequencing has become the new watchword for the biological researchers, as this tells them exactly what is going on at cellular level in health and disease. However, it is a partial ...
The amino acid abundances of two Ryugu particles were measured and compared with their rocky components. The results demonstrate the important role that water plays in the formation of amino acids on ...
