How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals ...

An easy method for efficiently identifying proteins that interact with bioactive molecules has been developed by chemical biologists at RIKEN. This innovation, published in ChemBioChem, could help to ...

Proteins are the infinitely varied chemicals that make cells work, and science has a pretty good idea how they are made. But a critical aspect underlying the machinery of protein manufacture has long ...

The nucleolus is where ribosomal RNA (rRNA) is transcribed, processed, and assembled into the building blocks of ribosomes, the molecular machines that make proteins. Researchers discovered that rRNA ...

Volume 17, Issue 6, on June 16, 2025, titled “rDNA copy number variation and methylation from birth to sexual maturity.” ...

When ribosomes go rogue Unusual variations in the cellular protein factory can skew development, help cancer spread, and more. But ribosome variety may also play biological roles, scientists say.

One of the oldest known molecules, the ribosome, creates proteins based on a copy of the genetic code found in the genome, known as mRNA. Scientists have believed that the ribosome performed the ...

On Wednesday Florida’s state surgeon general Joseph Ladapo called for stopping the use of messenger RNA–based COVID vaccines, citing—without convincing evidence—concerns about DNA ...
