Overview
- A PLOS One survey published Wednesday of 334 U.S.-registered physicians found about 27.9% said revival after cryonic preservation was plausible.
- Neurosurgeons were far more optimistic than other specialties, giving a 72% median chance of success versus a 25.5% median across all respondents.
- A clear majority (70.7%) supported prescribing anticoagulants such as heparin to dying patients to improve preservation quality.
- Around 44% of surveyed doctors said initiating preservation procedures before cardiac arrest should be allowed, a step that raises legal and ethical questions.
- The study cites recent lab advances that preserved human brain architecture in 2024 and recorded neural activity in vitrified mouse tissue in early 2026, but the authors’ ties to cryonics groups and remaining technical barriers mean human revival is not demonstrated.
