Two separate laboratory breakthroughs have produced RNA molecules that can build copies of themselves or assemble functional structures without any help from proteins or DNA. These results offer the ...
A strand of RNA just 45 nucleotides long can copy its own complementary sequence in frozen conditions that may resemble early Earth, according to a study published in Science in early 2026. The ...
Recent research showed that an artificially constructed RNA self-replicating system modeling primitive life at the origin of life evolved to become more prone to extinction under certain experimental ...
A study demonstrates that fully synthetic molecules can undergo self-replication, mutation and selection — hallmarks of Darwinian evolution — without relying on DNA or proteins. Darwinian evolution ...
The onset of Darwinian evolution represents a key step in the transition of chemical systems into living ones. Furthermore, Darwinian evolution is a tremendously powerful engine of invention, but one ...
Self‑replicating circular RNA persists in extreme environments: Insights from hot spring microbiomes
Although the genetic material of most living organisms is DNA, various self-replicating agents rely instead on RNA, including RNA viruses and viroids, which are infectious RNA molecules that are ...
Back in high school chemistry, I remember waiting with my bench partner for crystals to form on our stick in the cup of blue solution. Other groups around us jumped with joy when their crystals formed ...
