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.
New AI model predicts protein structures with 99% accuracy
Scientists at the University of XYZ have unveiled an advanced AI model that achieves 99% accuracy in predicting protein structures.

Images show rifampicin's effects on E. coli bacteria
Scientists have captured the first detailed images revealing how the common antibiotic rifampicin disrupts E. coli bacteria at a molecular level. Using advanced cryo-electron tomography, researchers visualized the drug binding to bacterial machinery, halting growth. The findings, published in Nature, offer new insights into antibiotic mechanisms.
Sperm from older men carry more genetic mutations
Researchers have confirmed that sperm in older men accumulate genetic mutations over time. This increases the risk of transmitting diseases to offspring. The percentage of sperm with potentially serious mutations rises with age.
Algae pigment siphonein protects against sunlight damage
Marine green algae have evolved a pigment called siphonein that shields their photosynthetic machinery from intense sunlight. Researchers from Osaka Metropolitan University discovered how this carotenoid efficiently quenches harmful energy states. The finding could inspire more durable solar technologies.
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.
