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

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 ...

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

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

RNA can act as an intermediary between the genome and the cell; active genes are transcribed into messenger RNA molecules, for example. While RNA can perform a variety of crucial functions, it is also ...

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

(Nanowerk News) Some Covid-19 vaccines safely and effectively used lipid nanoparticles (LNPs) to deliver messenger RNA to cells. A new MIT study shows that different nanoparticles could be used for a ...

RNA sequencing (RNA-seq) is a powerful tool in diagnosing Mendelian disorders, but the optimized sequencing depth for this technology has not yet been determined. In a new study published in the ...

There are many molecules with therapeutic potential, but it can be a challenge to deliver them to the right places at the right times. RNA is one such molecule; the sequences for different proteins ...

In mice and human cell cultures, researchers showed that novel nanoparticles can deliver a potential therapy for inflammation in the brain, a prominent symptom in Alzheimer's disease. In mice and ...
