In a stunning breakthrough, scientists have discovered what they refer to as a “third state” between life and death—a liminal phase that challenges our fundamental understanding of biology and opens up possibilities for transformative applications in medicine, technology, and even the concept of life itself. This “third state,” observed in new types of organisms called biobots, redefines cellular behavior and raises fascinating questions about the boundaries of life, death, and the potential to manipulate both.
Biologists Dr. Peter Noble and Dr. Alex Pozhitkov, co-authors of a new review on the subject, explained in The Conversation that this state lies somewhere between traditional biological definitions of life and death. While life and death have conventionally been seen as distinct and irreversible states, this third category introduces a new realm for cells that neither follow programmed life cycles nor succumb to death in typical ways. Their findings have the potential to redefine biology, shift perspectives in healthcare, and expand the frontiers of technology.
Understanding the Third State
The “third state” is not merely a result of cellular survival; rather, it’s characterized by behaviors and functions that challenge standard definitions of life and death. Traditional examples of development, like caterpillars becoming butterflies or tadpoles maturing into frogs, represent predictable transformations. However, the cells in this third state exhibit behaviors that are not predetermined or fixed, pointing to a unique flexibility in their cellular potential.
One example includes the creation of biobots, or biologically engineered living robots, which function in ways that are neither entirely living nor dead. Unlike cancerous tumors, organoids, or the famous HeLa cells that continuously divide in petri dishes, these biobots appear to activate novel cellular functions without evolving into more complex organisms. This uniqueness sets them apart from other lab-grown cells and introduces an entirely new dynamic in cellular biology.

Implications for Science and Medicine
The discovery of the third state has massive implications for scientific research and medical applications:
- Revolutionizing Regenerative Medicine: Understanding the third state could be groundbreaking for regenerative medicine and organ transplantation. By learning to control or induce this third state in human cells, scientists may be able to engineer cells that can regenerate or repair damaged tissue in ways previously thought impossible.
- Possibilities in Cancer Research: The third state offers new insight into the behavior of cells that survive in non-traditional ways. If scientists can replicate this state in cancerous cells, it might lead to treatments that encourage tumors to enter a third state where they can be controlled or manipulated without aggressive measures like chemotherapy.
- Ethics and the Concept of Life: The third state challenges ethical considerations around life, death, and the use of living cells in research. It forces a reconsideration of what constitutes a living organism and what ethical guidelines should be followed in research on cells that do not clearly fit into conventional categories.
Dr. Noble explains, “This third state is an entirely new territory for biological science. The more we study it, the more we recognize it could redefine treatments for degenerative diseases and expand the boundaries of life itself.”
Transforming the Future of Technology and Biobots
The emergence of the third state has also triggered interest in technology, particularly in robotics and artificial intelligence. Biobots—small, living robots made of cellular material—are already showing potential in various applications, from targeted drug delivery to environmental monitoring. By functioning within this third state, biobots could be designed to accomplish tasks that traditional robots cannot, taking advantage of the flexibility and adaptability of biological materials.
- Enhanced Biobots for Medical Use: The third state could lead to biobots that better adapt to their environments and perform complex tasks within the human body. These biobots could deliver drugs precisely to cancerous cells, repair damaged tissues, or even fight infections at a microscopic level. This could herald a new era of precision medicine.
- Applications in Environmental Technology: Biobots engineered in this third state might also be deployed in environmental monitoring, detecting pollutants or harmful substances in real time. Their biological foundation allows them to interact with their environment in ways traditional machines cannot, offering a new tool for environmental preservation.
- Redefining AI and Robotics: This third state has broader implications for the fields of artificial intelligence and robotics. Researchers are exploring how biobots with the ability to survive in this non-traditional cellular state can improve adaptability in AI systems, offering a future where “living” robots could perform essential services, manage hazardous conditions, or explore inaccessible places.
As AI and biobot technology converge, researchers are excited by the possibility of creating systems that can learn and adapt in ways closer to biological organisms. For more on the growing field of biobots, visit MIT Technology Review.
Life, Death, and the New Definition of Existence
The discovery of the third state opens up profound philosophical questions about what it means to be alive. Traditionally, biological life is defined by birth, growth, reproduction, and death; anything outside this process has been seen as inanimate or non-living. Yet, the third state brings new dimensions to these definitions, suggesting that life could exist in forms that don’t necessarily conform to known life cycles.
The flexibility of cells in the third state suggests that life and death may not be fixed endpoints, but parts of a spectrum that cells can move across. Some researchers propose that this state could point toward longer life spans, regenerative capabilities, and even the potential to reverse cellular damage in humans.
“Understanding this third state could be as transformative as the discovery of DNA,” Dr. Pozhitkov notes. “It’s reshaping the way we think about life itself and has the potential to redefine the boundaries of science and medicine.”
The Future of the Third State in Science, Medicine, and Technology
As research on the third state progresses, it’s likely to yield groundbreaking applications that reshape human health, environmental sustainability, and the integration of biology with technology. Scientists are optimistic that understanding this state will enable us to develop better treatments, create adaptive biobots, and rethink our ethical approach to life sciences.
This discovery is just the beginning, but it’s a promising step that could lead to one of the most profound shifts in modern science. The future holds exciting potential as we learn more about what the third state can unlock for humanity.
