Scientists have discovered that DNA damage in melanocyte stem cells can lead to hair graying through senescence, but in the presence of carcinogens, these cells avoid this process and expand, increasing cancer risk. The study links the biological pathways of aging, hair color change, and cancer development, highlighting how stem cell stress responses can diverge into either protective exhaustion or dangerous expansion, with implications for understanding melanoma and aging.

Researchers at King's College London have made significant progress in growing lab-based human teeth using innovative scaffolds and cell interactions, aiming to develop biological replacements that could be more natural and accepted by the body than current implants. While challenges remain, this research paves the way for future dental treatments that could fully regenerate teeth from a patient's own cells within the next decade.

Research suggests that hair graying may be linked to a natural defense mechanism against cancer, with stem cells in hair follicles responding to DNA damage by either differentiating and causing graying or avoiding differentiation to prevent tumor formation, based on a mouse study. However, further research is needed to understand implications for humans.
