Human Body Undergoes Two Bouts Of Rapid Physical Transformation On Molecular Level During Middle Age, Research Finds

The Washington Post (8/14, Sands) reports new research found that middle age is “when the human body undergoes two dramatic bouts of rapid physical transformation on a molecular level.” In the study, scientists “tracked age-related changes in over 135,000 types of molecules and microbes, sampled from over 100 adults.” Researchers “discovered that shifts in their abundance – either increasing or decreasing in number – did not occur gradually over time, but clustered around two ages.” The study found that “on average, the changes clustered around the ages of 44 and 60.” The findings were published in Nature Aging. NBC News (8/14, Carroll) reports the changes “may be causing significant differences in cardiovascular health and immune function.”
