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 ...

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

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

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

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 ...

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 ...

(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 ...

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 ...

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 ...

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 ...

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 ...
