How the brain helps protect fertility from heat-induced damage
Researchers have discovered that the brain uses RNA-based signaling to protect reproductive cells from heat-induced damage. This study in C. elegans reveals a pathway where neurons actively influence germline resilience to environmental stress.
Why it matters
Understanding how the brain regulates fertility under heat stress could provide insights into the impact of climate change on reproductive health across species.

DOI: 10.1016/j.cub.2026.06.016 As global temperatures continue to rise, scientists are racing to understand why heat so profoundly threatens fertility across the animal kingdom. A new study from the Hebrew University of Jerusalem and collaborators has uncovered a surprising answer: The brain itself may help decide whether reproductive cells can withstand environmental stress.
The research by Dr. Yonatan Tzur of Hebrew University, together with Dr. Chee Kiang Ewe, Dr. Hanna Achache and Professor Oded Rechavi of Tel Aviv University, reveals that nerve cells communicate with reproductive cells using RNA-based signaling, enabling the brain's perception of the environment to influence fertility long before damage occurs.
