Scientists have looked at hundreds of research papers to understand how we measure biological aging. This review looked at the different ways researchers track how our bodies age at a cellular level. By looking at many studies at once, they could see what markers are most common.
Most of the research focused on markers that do not involve DNA methylation. These markers help scientists see how cells change over time. The review showed that the types of markers people choose to study have changed as technology has improved.
In addition to markers, the review looked at new ways to measure aging. These new metrics help scientists better understand the processes that make us older. By identifying where research is consistent and where it is still confusing, scientists can better plan future studies.
This broad look at the data helps the scientific community see the big picture. It highlights the different tools available to study aging and points toward areas where more research is needed to improve our understanding of how the human body ages.
