Computer vision 'sees' our organs age at different rates
We tend to think of age as a linear progression marked by birthdays and milestones dictating when we can vote, drink, rent a car or pass beyond the crest of an arbitrary metaphorical hill. When scientists look at how organs age, however, it doesn't match the idea that we gradually grow older with each tick of the clock.
Scientists at Sanford Burnham Prebys Medical Discovery Institute have discovered that our organs age at different rates, challenging the traditional notion of a linear aging process. By analyzing 25,000 scanned histopathology images of 40 types of human tissue, researchers identified three major aging patterns and mapped underlying molecular changes.
The study, published in Nature Aging, reveals that some tissues exhibit accelerated aging, while others age more slowly or in a biphasic manner. Ovarian tissue, for example, showed accelerated aging between ages 35-40 and 55-60, coinciding with fertility decline and menopause. This research could lead to the development of tissue-specific treatments to promote healthier aging and overall healthspan.
