Pando, a massive grove of over 40,000 trees in Utah, is considered the world's largest and possibly oldest living organism, potentially dating back 16,000 to 80,000 years. Originating from a single seed, Pando's age was estimated through genetic sequencing of over 500 samples, revealing a surprisingly uniform genetic makeup despite its vast size. The research, not yet peer-reviewed, highlights Pando's resilience and the challenges it faces from environmental threats. Efforts are underway to protect and rejuvenate this ancient organism.
Researchers from Osaka Metropolitan University have developed an artificial intelligence (AI) model that can estimate a person's biological age by analyzing chest X-rays. The study found that the higher the AI-estimated age compared to the person's actual age, the more likely they were to have chronic diseases such as hypertension, COPD, liver disease, lung disease, and chronic renal failure. The AI model could serve as an indicator for age-related diseases and aid in early detection and intervention, but further research is needed to confirm causality and compare it with other biological age markers.
Scientists at Osaka Metropolitan University have developed an advanced AI model that accurately estimates a patient's chronological age by analyzing chest radiographs. The AI model showed a strong correlation between estimated age and chronological age, paving the way for improved early disease detection and intervention. The study also found that a higher AI-estimated age compared to chronological age was positively correlated with various chronic diseases, such as hypertension and chronic obstructive pulmonary disease. The researchers aim to further develop this research to estimate the severity of chronic diseases, predict life expectancy, and forecast surgical complications.
New research suggests that the Mare Imbrium, the region of the moon where the "man in the moon" is located, is much older than previously believed. By correlating dating results from moon rock samples with the sites they were collected from, researchers have found that large portions of the lunar crust are around 200 million years older than previously thought. This discovery could help scientists understand the early evolution of life on Earth and other planets, such as Mars.
