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 ...

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 ...

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.

The discovery of ribosomes dates back to the 1950s, when George Palade first observed dense particles in the cytoplasm of cells using electron microscopy. These particles were later named "ribosomes" ...

Under stress, animal cells pair inactive ribosomes into RNA-linked disomes. A ribosomal RNA “kissing loop” joins them, protecting ribosomes and reducing protein synthesis to conserve energy.<br /> ...

Hyperthermophilic archaea are true survival experts. They thrive in boiling hot springs and deep-sea vents—environments lethal to nearly all other forms of life. Subscribe to our newsletter for the ...
