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 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists ...

Neurons have a "hibernation mode." Scientists discover how brain cells use RNA tentacles to lock their protein factories together to survive when energy is low.

Researchers are embarking on the RNA equivalent of the Human Genome Project, including sequencing all the chemical ...

New research shows that lipid nanoparticles used in mRNA vaccines may deliver RNA more effectively when their structure is disorganised.

Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...

Inside every cell, thousands of molecular signals collide, overlap, and compensate, obscuring the true drivers of gene ...

Researchers at the MRC Laboratory of Molecular Biology in Cambridge have discovered a ribozyme that is shockingly small, yet ...

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

The tiny fatty capsules that delivered COVID-19 mRNA vaccines into billions of arms may work better when they're a little ...
