Bumblebee Queens Survive Floods by Breathing Water and Slowing Metabolism

New research shows Bombus impatiens queen bees can survive extended submersion during diapause by extracting oxygen from water (likely via a gill-like structure), using anaerobic metabolism and profound metabolic depression to dramatically cut energy needs; in lab tests, CO2 production dropped from about 15.4 to 2.4 µL h-1 g-1 after eight days underwater, illustrating a remarkable flood-tolerance strategy that could help colonies weather crises and hints at resilience in other terrestrial insects; the study is published in Proceedings of the Royal Society B.

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.
