A buildup of a structural protein called F-actin inside aging brain cells appears to cripple the cellular waste-clearing machinery that keeps neurons healthy, according to a study in Drosophila fruit ...

The presence of an organelle called the fusome in species as diverse as Drosophila and mammals indicates an ancient, conserved programme of germ cell development.

Innovations in imaging and genetic engineering are coming together to probe the biophysics of cytoplasm inside living animals.

Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls ...

Mitochondria possess their own mRNA translation system, mediated by specialized mitoribosomes. Dysregulation of mitochondrial translation disrupts metabolic homeostasis and is linked to various ...

A study on worms led by researchers from Vanderbilt University School of Medicine in the US has uncovered a previously unknown adaptation to aging that actively remodels one of the largest and most ...
