Understanding Cryonics: Tomorrow Bio's Vision for Human Cryopreservation

In the quest for extending human life and defying the finality of death, cryonics has emerged as a fascinating field. This scientific endeavor involves preserving individuals at extremely low temperatures immediately after legal death, with the hope that future medical advancements can restore them to life and health. Leading this ambitious venture is Tomorrow Bio, a Berlin-based startup dedicated to making human cryopreservation a viable reality.

What is Cryonics?

Cryonics is the practice of preserving legally deceased individuals at sub-zero temperatures to halt biological decay. The underlying premise is that future technological and medical breakthroughs may enable the revival and healing of these preserved individuals. The process involves replacing bodily fluids with medical-grade antifreeze solutions to prevent ice crystal formation, which can damage tissues during the freezing process. Once prepared, bodies are stored in liquid nitrogen at temperatures around -196°C (-320°F) for long-term preservation.

Tomorrow Bio's Approach to Human Cryopreservation

Founded by Dr. Emil Kendziorra, Tomorrow Bio aims to advance the science of biostasis and offer high-quality cryopreservation services. The company's mission is to make biostasis accessible to all, ensuring that individuals have the opportunity to benefit from future medical technologies. As of early 2025, Tomorrow Bio has successfully cryopreserved several individuals and has a growing list of clients who have signed up for their services.

The Cryopreservation Process at Tomorrow Bio

The journey of cryopreservation with Tomorrow Bio involves several critical steps:

1. Preparation Before Legal Death: Clients, referred to as "patients," enroll in the program while still alive. This enrollment includes comprehensive medical evaluations and the establishment of legal and financial arrangements to ensure the process proceeds smoothly after legal death.
2. Stabilization After Legal Death: Immediately following the declaration of legal death, a specialized medical team initiates procedures to maintain oxygenation and circulation to preserve the body's viability.
3. Cryoprotectant Perfusion: The patient's blood is gradually replaced with a cryoprotectant solution to prevent ice crystal formation, which can cause cellular damage during the freezing process.
4. Cooling to Storage Temperature: The body is slowly cooled to -196°C (-320°F) and then transferred to a long-term storage facility, where it remains in liquid nitrogen until future revival becomes possible.

Ethical and Scientific Considerations

The concept of reviving the deceased through cryonics raises numerous ethical, philosophical, and scientific questions:

• Scientific Feasibility: Currently, there is no proven method to revive a cryopreserved human. While certain organisms and tissues have been successfully cryopreserved and revived, the complexity of the human body presents significant challenges.
• Ethical Implications: Cryonics prompts debates about the definition of death, the allocation of medical resources, and the potential societal impacts of extending human life indefinitely.
• Legal and Regulatory Aspects: Different countries have varying regulations regarding cryonics. Navigating these legal landscapes is crucial for companies like Tomorrow Bio to operate effectively and ethically.

The Future of Cryonics and Tomorrow Bio's Role

As medical technology continues to evolve, the possibilities surrounding cryonics become increasingly intriguing. Tomorrow Bio is at the forefront of this exploration, investing in research and development to overcome current limitations. The company's commitment to advancing biostasis science includes collaborations with research institutions and participation in scientific discourse to address the challenges inherent in human cryopreservation.

Conclusion

Cryonics represents a bold intersection of science, ethics, and the human desire to transcend mortality. Companies like Tomorrow Bio are pioneering efforts to transform this concept into reality, offering individuals the hope of a second chance at life through human cryopreservation. While significant hurdles remain, the ongoing advancements in medical and cryogenic technologies may one day turn the dream of reviving the deceased into a scientific achievement.
