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 alive and functioning. When cells experience stress—such as lack of nutrients ...

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.

A recent study by Fred Hutch biochemist Christopher Lapointe, PhD, and his colleagues, uses innovative lab techniques to ...

Many proteins have a complex architecture that enables biological functions. Molecules can bind to specific sites on a ...

Many proteins have a complex architecture that enables biological functions. Molecules can bind to specific sites on a protein and alter its function. A team at HZB has now investigated the Nsp1 ...

The origin of the nucleus remains hotly debated among scientists, but new imaging and genomic data are shedding light on this billion-year-old mystery.

Duckweed is the fastest-growing flowering plant, but new knowledge of duckweed genetics discovered by Adelaide University ...

Polyamines—natural molecules found in every living cell—have become stars in the longevity world for their ability to boost cellular cleanup and support healthy aging. But there’s a dark twist: high ...

Researchers discovered a protein that acts as a molecular switch driving cocaine addiction by altering gene activity in a ...

Can anti-ageing supplements fuel cancer? A new study examines how polyamines like spermidine affect protein synthesis in cancer cells and what it means for supplement users.
