40,000-Year-Old Stone Age Symbols May Be a Precursor to Written Language

Geometric marks carved into Paleolithic tools and figurines were not random decoration. A new computational analysis shows that Ice Age humans used these repeated sequences of dots, lines, and notches to encode information. Published in Proceedings of the National Academy of Sciences, researchers examined more than 3,000 signs found on…

Stepwise differentiation from precursor intermediates and distinct Th1 checkpoints promote CD4 Th1 cell differentiation during chronic viral infection

Proceedings of the National Academy of Sciences, Volume 123, Issue 5, February 2026. SignificanceTh1 CD4+cells are essential for viral control during chronic infection, but their differentiation becomes progressively restricted. Here, we identify a Th1 precursor intermediate subset, describe the stepwise differentiation of Th1 cells ...Read More
