With the inventions of transmission electron microscopy (TEM) in 1931 and scanning electron microscopy (SEM) shortly after in 1937, scientists gained an unprecedented ultrastructural view of the ...

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 /> ...

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.

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 ...

Joachim Frank and colleagues used cryo-electron microscopy to generate this image of the ribosome bound to release factor RF2 in the presence of a stop codon and a P-site tRNA (left). Then the team ...

Ribosomes are miniature factories of life. A detailed understanding of their mechanical mastery lays the foundations for all manner of applications – from manufacturing vaccines to developing new ...

Scanning Electron Microscopy (SEM) has revolutionized the realm of microscopic analysis. By delivering astonishingly detailed images of minuscule entities such as insects, bacteria, or even the ...

Cryo-EM structure of the Giardia ribosome reveals a highly compact, GC-rich rRNA with eukaryotic r-proteins. (A) Structure of the Giardia ribosome with all the r-proteins colored (SSU, shades of blue ...
