Using a tiny thermometer, researchers record fluctuations of more than 7 Kelvin in sea slug neurons when a heat-generating mitochondrial process is switched on.

Organelles isolated from two types of neurons and a nonneuronal astrocyte in the mouse cerebellum showed varying levels of proteins, hinting at functional differences.

A study finds variations in the levels of proteins for some important processes among organelles from different brain cells.

Cardiomyocytes made from iPSCs aboard the International Space Station had upregulated mitochondrial functioning.

From regulating each other’s gene expression to encoding different parts of the same proteins, the two genome types in every eukaryotic cell are far from independent.

Interactions between mitochondrial and nuclear genomes have further-reaching effects on physiological function, adaptation, and speciation than previously appreciated.

New evidence points to a waste-clearing problem in patients’ cells, rather than the accumulation of protein tangles, as the root cause of the neurodegenerative disease.

Damage to the lysosome, the organelle that removes excess proteins, lipids, and other materials, might be at the root of the disease.

Scientists uncover a potential reason why redder house finches have better health.
