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 /> ...
Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells ...

Structures 3D printed inside living human cells that has one-fifth width of a human hair
Human cells are extremely small and tightly packed – at about 20 micrometers across, roughly one-fifth the width of a human hair, each cell contains a dense mix of proteins, organelles, and molecular ...
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.

Animal and plant cells have different energy-producing structures inside them. For animals, that’s mitochondria, which convert chemical energy from food into a form that our cells can use. Plants and ...
A 3D rendering showing the internal structure of an animal cell, with several round or wavy structures inside a border. It turns out that the redox state of a cell, such as the animal cell shown, is ...
The ability of plants to convert sunlight into food is an enviable superpower. Now, researchers have shown they can get animal cells to do the same thing. Photosynthesis in plants and algae is ...
