Population surveys and research studies suggest that meaningful social connections are strong predictors of health and longevity. In other words, a sense of belonging to a social group and strong social bonds appear to be linked with better health and a longer lifespan.

Most earlier studies, however, primarily focused on the possible health-related benefits of receiving social support or interacting with others regularly. In contrast, the potential benefits of supporting and helping others remain largely unexplored.

Researchers at Georgetown University, Emory University and the University of Wisconsin–Madison recently carried out a study investigating the possibility that time spent supporting others is associated with brain health...

Over one billion people worldwide are over 60, and the population is projected to more than double by 2050. But as more people live into their 60s, 70s, and 80s, health care systems across the globe may face new challenges as they attempt to manage associated increases in age-related disease.

Metabolic biologist Andreas Stahl and preeminent longevity researcher Irina Conboy argue that the graying of the global population underscores the need to understand aging as a biological process, and how it might be slowed or reversed...

A large new study suggests that higher levels of a common amino acid called tyrosine may be linked to a shorter lifespan in men.

The research, published recently in the journal Aging, examined whether blood levels of two amino acids, phenylalanine and tyrosine, were connected to how long people live.

Amino acids are building blocks of protein. They are found in protein-rich foods such as milk, eggs and meat, and are also sold as dietary supplements.

Researchers from the University of Hong Kong and the University of Georgia analyzed health and genetic data from more than 270,000 people in the U.K. Biobank, a large long-term health study in the U.K.

At first, both amino acids appeared to be tied to a higher risk of death...

A team of researchers has found a way to turn the bacteria living in the digestive tracts of animals into factories that can produce compounds that promote longevity in their hosts—showing a potential new drug development strategy.

Janelia Senior Group Leader Meng Wang and her team study longevity and were interested in seeing how they could transfer their research findings about longevity-promoting compounds into practical applications.

One idea they had was to induce the body’s gut microbiota—a collection of bacteria in th...
