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 ...

New 3D reconstructions of a key sensory organ in ctenophores reveal an unexpected structural and functional complexity. The ...

More than 1.5 billion years ago, a momentous thing happened: Two small, primitive cells became one. Perhaps more than any event—barring the origin of life itself—this merger radically changed the ...

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 ...

Researchers have found a new, dynamic protein structure in cells. Every cell contains millions of protein molecules. Some of them have the ability to phase-separate to form non-membrane-bound ...

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 /> ...

Guided by the work of Rosalind Franklin, James Watson and Francis Crick discovered the the twisted-ladder structure of DNA in 1953, a finding that gave rise to the modern field of molecular biology.
