Early Earth chemistry: Triplet RNA building blocks and freeze-thaw cycles enable self-replication in water
Chemists at UCL and the MRC Laboratory of Molecular Biology have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth—a key process in the origin of life. Scientists ...
New experiments suggest that RNA, a crucial molecule for life, could have naturally formed on early Earth or even arrived from space via asteroids.
Sugars essential for life were found for the first time alongside “space gum” on an asteroid hurtling towards Earth, indicating that our universe could be teeming with life, according to new research.
Oceans churned with lava. Air filled thick with smoke. Asteroids stormed down incessantly. Life during the Hadean Eon four billion years ago was a struggle, and yet that was when it began. 1,2 With no ...
Scientists detected all five nucleobases -- building blocks of DNA and RNA -- in samples returned from asteroid Bennu by NASA's OSIRIS-REx mission. Japanese collaborators detected all five nucleobases ...
