Mitochondrial function

A team demonstrated that ultrasound waves improved motility in sperm.

Reactive oxygen species cause mutations to DNA bases that can lead to cancer, but the long-blamed mitochondria could have been wrongfully charged.

Following decades of being called “the powerhouse of the cell,” researchers recently proposed a new description that reflects the multifaceted roles of mitochondria.

As scientists realize the multifaceted role of mitochondria, some feel that the “powerhouse of the cell” analogy is out of date.

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.

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

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.

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

The energy-producing organelles also send out parcels with antimicrobial compounds to help destroy pathogen invaders in macrophages.

The parasitic plant manages to go without a component of mitochondria found in all other multicellular life forms.

Mitochondria may sustain temperatures more than 10 °C warmer than human cells, say researchers. 

Mitochondria age differently depending upon whether they’re located in the liver, heart, or kidney, scientists find in flies and mice.
