Researchers have now uncovered the 3D structure of the RNA enzyme SAMURI. Their study provides insights into the development of ribozymes and the evolution of catalytically active RNA. Researchers led ...

Lipid nanoparticles (LNPs) are tiny fat bubbles that are used to deliver medicines, genes, and RNA into cells. However, in some cases LNPs can cause harmful inflammation as a result of the process of ...

In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these molecules form before life (and enzymes) existed? Why did some molecules end up ...

To our immune system, naked RNA is a sign of a viral or bacterial invasion and must be attacked. But our own cells also have RNA. To ward off trouble, our cells clothe their RNA in sugars, Vijay ...

For the first time, researchers have successfully extracted and decoded RNA from an extinct animal. The thylacine, also known as the Tasmanian tiger, was a wolflike marsupial that went extinct after ...

Octopuses are curious and clever. They can solve mazes and puzzles, use tools, and are masters of camouflage. These complex abilities are powered by their sophisticated and giant brains. Now, in the ...

Scientists have discovered that neurons exposed to Botox (botulinum toxin A) don't just survive—they fight back. A new study shows that tiny fragments of tRNA, a type of genetic material, help protect ...
