lifespan

Researchers say there may be similar, human genes whose effects on lifespan vary by sex.

Fasting, eating only at certain times of day, and restricting overall calorie intake can collectively contribute to lifespan extensions in animals. Could the same hold true in humans?

Two studies show negligible rates of aging in some types of turtles and other cold-blooded creatures, but that doesn’t mean they’re immortal.

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.

Worms, flies, and yeast live longer if the fidelity of their protein-making machinery is improved, a study shows.

This evolutionarily ancient fish species has a lifespan that’s around five times longer than previously thought, and a gestation time of more than five years.

Genes related to the immune system stay active throughout the tree’s life.

Suppressing the natural age-related increase in neuronal excitation lengthens the lives of worms, and there are indications that the same may be true for mice and humans.

The science isn’t there yet, nor are the known interventions that ought to be combined with delivering such predictions.

Researchers develop an app that can estimate the biological age of a rodent from its mug shot—and could give a boost to the science of human aging in the process.

A demographer’s model suggests the “mortality plateau” in the extreme elderly could be explained by clerical errors. Not everyone agrees.

Some of the longevity that appears to run in families can instead be attributed to people choosing life partners with similar characteristics.

The researchers say that their results are evidence we haven’t yet reached a limit to human lifespan.

Species with larger pancreatic cells tend to have shorter lives, according to a study.  

Findings from a randomized, controlled trial finds that reducing food intake decreases metabolism and reduces oxidative damage to tissues and cells.

Crowdsourced data from Geni.com, which includes the actor Kevin Bacon, answers questions about marriage, migration, and more.

From extending lifespan to bolstering the immune system, the drug’s effects are only just beginning to be understood.

Maintaining dynamic connections among the body’s mitochondria is required for the health and life-extending benefits of low-calorie diets for nematodes.

High-fat, low-carbohydrate diets are shown to increase lifespan and preserve memory in two independent mouse experiments.
