mitochondria

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.

The mitochondria stolen via these tiny connections give tumor cells a metabolic boost while the T cells are left weakened, according to in vitro experiments.

While exploring suspended animation in mice, scientists discover how an enzyme can protect the brain from dangerously low levels of oxygen.

Vesicles containing fragments of the organelles released from stressed adipocytes protect the heart against oxygen deprivation, a study in mice shows.

Healthy people put through high-intensity interval training, or HIIT, displayed insulin resistance and mitochondrial dysfunction after working out excessively.

An enzyme pulled from toxic bacteria can enter the organelle and perform single-nucleotide DNA swaps.

A complete bird specimen uncovered in northeastern Siberia is radiocarbon dated to be roughly 44,000–49,000 years old.

The findings could represent a novel mechanism for relieving inflammatory pain.

New TALEN-based tools enable the organelle’s genome to be targeted and modified.

A handful of clinical trials are underway to find out whether drugs that target senescent cells can slow the ravages of old age.

Modified gene editing machinery enables targeted disruptions of mitochondrial genes in rice and rapeseed plants.

The accumulation of zombie-like cells seems to accelerate aging and promote aging-related disease. Researchers are trying to figure out how.

The functional, respiring organelles appear to be present in the blood of healthy people, but their function is yet unclear.
