‘This Is Powerful’: New Tech IDs Key Microbes in Seconds

Christina Szalinski More than half the cells in the human body are not human — they’re microbes. Each microbe makes unique molecules, or metabolites, and studying them is crucial for understanding the microbiome’s role in health and disease. But with so many microbes and metabolites floating around — literally trillions — how can you tell...

Health and zombie cells in aging

Peer-Reviewed Publication MAYO CLINIC With age, cells can experience senescence, a state where they stop growing but continue releasing inflammatory and tissue-degrading molecules. When a person is young, the immune system responds and eliminates senescent cells, often referred to as zombie cells. However, zombie cells linger and contribute to various age-related health problems and diseases....
