Study links graying hair and melanoma to stress responses in pigment stem cells
Heather Vogel Larawang ginawa ng AI Fact checked
Japanese researchers report that hair graying and melanoma can arise from the same melanocyte stem cells, which take different paths depending on DNA damage and local signals. Published online October 6, 2025 in Nature Cell Biology, the University of Tokyo-led study outlines a protective differentiation program that promotes graying and how carcinogens can subvert it to favor melanoma.
Scientists uncover universal thermal performance curve for all life
Researchers at Trinity College Dublin have discovered a universal thermal performance curve that governs how every living organism responds to temperature changes. This pattern, applicable from bacteria to fish, shows performance peaks at an optimal temperature before sharply declining, highlighting limits to adaptation in a warming world. The findings, published in PNAS, suggest evolution cannot escape this fundamental rule.
Scientists identify new protein role in brain development
A recent study has revealed how a specific protein influences neural connections during early brain growth. Researchers from the University of California found that disrupting this protein leads to impaired synapse formation in animal models. The discovery could pave the way for better understanding neurodevelopmental disorders.
First Nitrogen-Fixing Organelle Confirmed
Scientists have confirmed the existence of the first-ever nitrogen-fixing organelle in a eukaryotic cell, marking a key advancement in understanding cellular evolution and nitrogen cycles.
Flatworm stem cells respond to distant cues, study finds
