A strand of RNA just 45 nucleotides long has been discovered to perform two key reactions required for self-replication. The ...

Scientists discover QT45, a self-replicating RNA molecule, offering insights into the origins of life on Earth.

A forested hill and clouds are in the background of an image of a shallow pool of steaming water, with the ground underneath colored in shades of beige, red, and brown. Life may have first emerged in ...

Life may have begun when RNA molecules began to replicate themselves, and now we’ve finally found an RNA molecule that is very close to being able to do this ...

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 ...

Cambridge, have discovered a tiny RNA molecule capable of copying itself - a key step toward understanding how life may have ...

One of the greatest mysteries of our planet is how a soup of lifeless chemicals transformed into the first living cell. There are several competing theories about where this happened, from frozen ...

Scientists may have discovered a reaction that provides the “missing link” to help explain how early life formed on Earth about 4 billion years ago. All living things contain ribonucleic acid, ...

Two of life’s essential ‘building blocks’ are DNA and RNA, forms of nucleic acid which carry genetic information from one generation to the next. RNA, or ribonucleic acid, is a polymer composed of ...

And now what is so new with that? Bees fly from one flower to the next, or brain information is transported by stimulating target neurons by nanoelectricity and chemical transmitter molecules and so ...

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 ...
