Telomere Length Inheritance: Why It Matters for Health
Telomeres: what they are and why they shorten Telomeres are protective caps at the ends of chromosomes, made of repetitive DNA and specialized proteins. Each time a cell divides, these caps shorten a little. When telomeres become critically short, cells stop dividing in a state called cellular senescence. This process is linked to chronic inflammation…

Telomere Length Inheritance and the Parent-of-Origin Effect
Telomeres: The Small Shields at Chromosome Ends Telomeres are the protective caps at chromosome ends, composed of repetitive DNA sequences and protective proteins. Each time a cell divides, these caps shorten, and once they become critically short, the cell halts division in a state called cellular senescence. This natural limit is linked to chronic inflammation…

Mitomeiosis: Scientists Grow Human Eggs From Skin Cells in Groundbreaking First
What is mitomeiosis and why it matters? A team of US researchers has reported a proof‑of‑concept technique that could, in the long term, help infertile people have biologically related children. The approach, named mitomeiosis, blends two fundamental cell‑division processes to coax skin cells into behaving like reproductive cells — eggs — capable of being fertilised…
