Studies have shown that caloric restriction can drastically increase the lifespan of a range of animals. On the path to determining whether humans could benefit from the same lifestyle, a 10-year study on lemurs has now found that animals on the diet lived almost 50 percent longer than usual.

C. elegans is a pretty unassuming worm, but its simplicity makes it a great model to study biological processes. Researchers at the University of Michigan have now uncovered how the worm’s brain and gut communicate with each other to coordinate aging throughout the body.

Rather than focusing on a longer lifespan, it’s a better to improve our “healthspan,” the time we can enjoy good health. A new study from Brown University has linked the protein Sirt4 with an extended healthy lifespan in fruit flies, and the find may carry across to humans.

The human body obviously has biological limits, with a review of 120 years of historical records now suggesting they may have already been reached in terms of life expectancy, height and sporting performance – and if we aren't careful they could start going backwards.

A study looking at genetic correlations among people with long-living parents has more than tripled the number of genetic variants associated with a longer lifespan and unexpectedly revealed potential gender-specific genetic pathways to a longer life.

A new study has found that many genes identified as potentially responsible for intelligence, could overlap with a range of conditions from increased lifespan to some autoimmune disorders.

New research may have finally cracked the puzzle of how eating less can help you live longer. A team at Temple University has found that epigenetic changes that occur with age can be slowed through a calorie-restricted diet.

Are carbs the new fat? For much of the 20th century, doctors suggested we avoid high-fat foods, but two new companion studies are suggesting a ketogenic diet – high fat, low protein, and low carbohydrates – could enhance memory, improve physical strength and extend lifespan.

A team at the University of Adelaide has been working to create an AI system that can predict a person’s lifespan just by studying images of their organs, and its early results show its predictions are just as good as a human doctor.

Two concurrent long-term studies came to conflicting conclusions about the health benefits of caloric restriction, but by comparing their results and accounting for other variables, scientists have now determined that caloric restriction does help monkeys stay healthier and live longer.
