Researchers seeking to understand how life may have emerged from Earth’s primordial soup have found an interesting behavior of ribonucleic acid (RNA), which they suggest could have given way to ...
BUFFALO, N.Y. — The RNA world theory suggests that life on Earth began with RNA molecules that copied themselves. It’s believed this self-replication eventually gave rise over millions of years to DNA ...

LA JOLLA (March 4, 2024)—Charles Darwin described evolution as "descent with modification." Genetic information in the form of DNA sequences is copied and passed down from one generation to the next.
Nitriles, a class of organic molecules with a cyano group, that is, a carbon atom bound with a triple unsaturated bond to a nitrogen atom, are typically toxic. But paradoxically, they are also a key ...
MINING FOR RNA: James Ferris's group at Rensselaer re-creates how nucleotides might have joined on ancient mineral surfaces. The RNA world hypothesis has fueled diverse research approaches, drawing ...
The RNA Institute at the University at Albany’s College of Arts and Sciences presented its annual “RNA Day” celebration Friday, with a special announcement involving the employment of Artificial ...

In his letter to the editor, Howard Deutsch writes that he has never heard anyone claim or conjecture that “ribonucleic acids were the first molecules of life” (C&EN, May 14, page 5). In fact, this ...
In 2018, the RNA Society endorsed Aug. 1 as annual World RNA Day, and depending on when you’re reading this article, the anniversary of that day is either upon you now or has likely passed you by ...
