What to know about How the brain helps protect fertility from heat-induced damage

Researchers from the Hebrew University of Jerusalem and Tel Aviv University have discovered that neurons in C. elegans worms use RNA-based signaling to protect reproductive cells from heat-induced damage. The study suggests that the nervous system integrates environmental cues to prepare the germline for stress, potentially offering insights into how various species adapt to climate change.
