A tiny wood frog holds one of nature's most extraordinary secrets: the ability to survive being almost completely frozen solid. When winter arrives, these North American frogs' hearts stop beating, their breathing ceases entirely, and up to 65% of their body water crystallizes into ice—yet come spring, they simply thaw out and hop away as if nothing happened.

Scientists studying this remarkable feat aren't just marveling at nature's resilience; they're unlocking breakthrough applications for human medicine. The wood frog's cryopreservation strategy is teaching researchers how to preserve human organs for transplant, potentially solving one of modern medicine's most persistent challenges. Understanding the biological mechanisms that protect the frog's cells from freezing damage could transform organ donation and save countless lives. Read the full story →
