Circadian rhythms are an evolutionarily adaptive trait most animals possess. The circadian clock allows animals to ...

In humans and other animals, signals from a central circadian clock in the brain generate the seasonal and daily rhythms of life. They help the body to prepare for expected changes in the ...

The portrayal of uncaring scientists without any thought for the animals being used in their research is far from the truth.

Horvath’s pan-tissue clock was miraculously accurate at predicting chronological age. It also seemed to reflect important underlying differences between chronological and biological age.

Researchers have developed a new “body clock" tool that measures biological age and may help forecast a person’s risk of disability or death. A longevity expert explains how it works.

Leaders around the world could reduce the biological threats facing humanity, and thereby move the hands of the Doomsday Clock away from midnight, by: Increasing surveillance of disease in humans, ...

Previous research in animals has offered several potential techniques for turning back the biological clock in specific tissues, including exercise and calorie restriction.

The appellation “wonder drug” might even be an understatement, reckons Harvard Health’s Robert Shmerling, MD. But why? Metformin is a first-line treatment for type 2 diabetes; its potential ...

Discover why biological age could matter more than chronological age for your health. Learn how new tests measure aging and what it means for your future.

Biological aging can’t be measured easily by a traditional clock because different organisms and cells change over time at different rates. New computational “clocks” can deduce ages by looking at ...

In humans and other animals, signals from a central circadian clock in the brain generate the seasonal and daily rhythms of life. They help the body to prepare for expected changes in the ...
