mitochondria

Researchers discover that neurons trade protein aggregates for microglial-derived mitochondria through tunneling nanotubes. 

Altering the rate of respiration in mitochondria changes how fast neurons grow, making mouse neurons grow more like human ones and vice versa, a study finds.

The Duke University cell biologist uses live-cell microscopy to reveal how brain cells rid themselves of damaged mitochondria and what goes wrong in neurodegenerative disease.

The findings answer the longstanding question of where these cells hold the mRNA needed to cope with the transcriptional halt preceding meiosis.

Genetic material pilfered from mitochondria may seal cracks in our genetic code, a study suggests.

Despite recent advances in the study of eukaryogenesis, much remains unresolved about the origin and evolution of the most complex domain of life.

A lot happened in the hundreds of millions years separating the first and last eukaryotic common ancestors, but when and how most features arose remains a mystery.

The discovery of gene variants in cases of hereditary spastic dysplasia could provide a diagnosis to affected families where no genetic cause could be found before.

By combining deep learning and electron microscopy, researchers now have a more detailed understanding of how fear changes the brain.

The cells’ mitochondria skip a key metabolic reaction that takes place in other cells in the body, a study finds.

Head and neck cancer cells lacking the peptide involved in energy production were less likely to metastasize in mice.

The discovery that a group of cell-infecting bacteria lived roughly 2 billion years ago stirs a longstanding controversy around which came first: phagocytosis or mitochondria.

Increasing mitochondrial activity in worms by engineering a light-activated proton pump into the organelle’s membrane extends the animals’ lifespan without evidence of health decline, according to a preprint.

The accidental finding marks the first time a phenomenon called cytoplasmic sterility, known to occur in plants, has been found in animals.

Studies have found that organisms can inherit mitochondria from male parents in rare instances, and both theoretical and experimental work hint that this biparental inheritance is more than just a fluke.

Sea otters are born with a supercharged metabolism that helps them stay warm in chilly waters.

Researchers identified a novel mechanism by which chemically induced stress is “remembered” by the mitochondria of worms more than 50 generations after the original trigger.

Neurons stressed with chemicals produce Wnt, which in turn triggers changes in the germline.
