Tiny Fish Reactivate Ancient Genes to Survive Prolonged Droughts
Researchers have discovered that the African turquoise killifish can survive months-long droughts by entering a state of suspended animation called diapause, utilizing ancient genes from over 473 million years ago. This adaptation involves genomic remodeling and increased production of very-long-chain fatty acids, which protect the embryos' developing organs. This finding could lead to new strategies for tissue preservation and combating age-related diseases.
