Hebrew University of Jerusalem Jun 18 2025 Scientists have discovered that neurons exposed to Botox (botulinum toxin A) don't just survive—they fight back. A new study shows that tiny fragments of tRNA, a type of genetic material, help protect nerve cells by blocking a specific kind of cell death called ferroptosis, which is caused by stress and iron buildup in the body. This breakthrough explains why Botox paralyzes muscles without killing the neurons that control them—and could lead to longer-
