Mini Brains Live Years in Lab | Science News
Scientists have cracked the code on keeping lab-grown mini-brains—called organoids—alive for years, revealing surprising insights into brain development and aging. These stem-cell-derived structures now mimic real human brain maturation, even showing DNA changes that hint at biological age. Researchers can now study neurological diseases like Alzheimer’s and Parkinson’s in ways never before possible. But with complexity comes caution: these organoids lack blood vessels and sensory input, and while they’re far from conscious, ethical debates are heating up as they evolve. The future of brain…
