Ribosomal RNA (rRNA) is a type of molecule and a key building block of the ribosome, the cell's protein-making machinery. rRNA accounts for much of the RNA in a cell, and it's crucial for life. It's ...

Ribosomal subunit assembly and biogenesis constitute a fundamental process vital for cellular protein synthesis across all domains of life. This complex, multi-step pathway involves the transcription ...

The ribosome is a fundamental cellular machine responsible for protein synthesis. Its complex structure, comprising distinct functional centres such as the peptidyl transferase centre (PTC) and the ...

Researchers at the Johns Hopkins Kimmel Cancer Center and Department of Radiation Oncology and Molecular Radiation Sciences uncovered a new tumor-suppressive response that could lead to novel ...

The chemotherapy drug azacitidine, a frontline treatment for blood cancers such as myelodysplastic syndromes and acute ...

Scientists profiling small non-coding RNAs in postmortem brain tissue from people with schizophrenia and bipolar disorder ...

Proteins that trigger cell senescence occupy much of the literature on aging, but a small RNA moves into the limelight. Further investigation into SNORA13 revealed that it modifies RNA bases in the ...

How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals danger. When the sun shines on your skin, what does it hit? When it causes a ...

Oceans churned with lava. Air filled thick with smoke. Asteroids stormed down incessantly. Life during the Hadean Eon four billion years ago was a struggle, and yet that was when it began. 1,2 With no ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...

In the microscopic world of bacteria, gene transfer is a powerful mechanism that can alter cellular function, drive antibiotic resistance and even shape entire ecosystems. Now an interdisciplinary ...
