The new findings strengthen the "RNA world" hypothesis that describes how the first life on Earth could have used RNA instead ...
Ribosomal RNA (rRNA) is a type of molecule and a key building block of the ribosome, the cell's protein-making machinery. rRNA accounts for much of the RNA in a cell, and it's crucial for life. It's ...
Ribosomal subunit assembly and biogenesis constitute a fundamental process vital for cellular protein synthesis across all domains of life. This complex, multi-step pathway involves the transcription ...

Israeli scientists say tiny organisms can revamp their own RNA to survive extreme heat
Using a novel method, Weizmann Institute of Science researchers map 16 types of simultaneous changes in dozens of samples; ...
We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...
Make no mistake, RNA is the main character of Nobel Prize-winning scientist Thomas Cech’s new book. The Catalyst is part ode to the oft-overlooked molecule and part detailed history of the scientists ...
How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals danger. When the sun shines on your skin, what does it hit? When it causes a ...
In the microscopic world of bacteria, gene transfer is a powerful mechanism that can alter cellular function, drive antibiotic resistance and even shape entire ecosystems. Now an interdisciplinary ...
