Third state" of existence between life and death confirmed by scientists

 


In science fiction movies like Frankenstein and Re-Animator, human bodies are revived, existing in a strange state between life and death. While this may seem like pure fantasy, a recent study suggests that a “third state” of existence might actually be present in modern biology.


The study, published in the journal Physiology, was led by Professor Peter Noble from the University of Washington in Seattle and Alex Pozhitkov from the City of Hope National Medical Center in Duarte, California.

“Life and death are traditionally viewed as opposites,” the researchers wrote in an article for The Conversation.

“But the emergence of new multicellular life-forms from the cells of a dead organism introduces a ‘third state’ that lies beyond the traditional boundaries of life and death.”

Cells come alive after death

In this third state, certain cells — when given nutrients, oxygen, bioelectricity, or biochemical signals — have the capacity to transform into new multicellular organisms, exhibiting new functions even after death. The researchers reviewed recent studies showing the incredible capability of cells to reorganize and take on new forms after the death of the organism. 

Skin cells become xenobots 

In 2021, U.S. scientists found that skin cells from dead frogs could adapt to a lab environment and spontaneously form multicellular organisms — actual living machines called “xenobots.” 

While most machines are constructed from materials like steel and plastic, which can degrade or break over time and have harmful side effects, living systems made from self-renewing and biocompatible materials would avoid those negative consequences.

These xenobots displayed behaviors far beyond their original biological purpose, using hair-like structures called cilia to move through their surroundings.

They also proved adept at material collection, information recording, self-healing, and limited replication.

Lung cells become anthrobots 

Similarly, other researchers discovered that human lung cells could self-organize into tiny multicellular organisms known as “anthrobots.” 

Anthrobots range in size from the width of a human hair to the tip of a sharpened pencil. Remarkably, these multicellular robots are designed to self-assemble and have demonstrated a pronounced healing effect on other cells.

These anthrobots could not only move independently but also repair themselves and heal damaged nerve cells nearby.

They have shown capabilities surpassing those of the xenobots, addressing critical questions about cellular assembly and cooperation in the body, and the potential for cells to be reassembled into different structures for varied functions.

Pausing” Cell Death Could Be the Key to Longevity

  Necrosis drives aging and disease by triggering damaging inflammation. Interrupting it may offer new treatments for chronic conditions and improve health in space travel. Necrosis, a form of uncontrolled cell death, may hold one of the most promising keys to altering the course of human aging, disease, and even space travel, according to a new study by researchers at UCL, the drug discovery company LinkGevity, and the  European Space Agency  (ESA). Challenging conventional thinking, the paper draws on evidence from cancer biology, regenerative medicine, kidney disease, and space health to argue that necrosis is not just a final stage of cell death, but a major driver of aging—and a potential target for intervention. Dr. Keith Siew, an author of the study from UCL Centre for Kidney & Bladder Health, said: “Nobody really likes talking about death, even cell death, which is perhaps why the physiology of death is so poorly understood. And in a way, necrosis is death. If...

Record-Shattering Molecule Stores Data at “Dark Side of the Moon” Temperatures

Image
  Researchers from The University of Manchester and The  Australian National University  (ANU) have developed a novel molecule capable of storing data at extremely low temperatures, comparable to the frigid conditions on the moon’s dark side at night. Their results, published in  Nature , point toward the potential for future data storage devices no larger than a postage stamp, yet capable of holding up to 100 times more information than today’s leading technologies. “The new single-molecule magnet developed by the research team can retain its magnetic memory up to 100 Kelvin, which is about minus 173 degrees  Celsius , or as cold as an evening on the moon,” co-lead author Professor Nicholas Chilton, from the ANU Research School of Chemistry, said. “This is a significant advancement from the previous record of 80 Kelvin, which is around minus 193 degrees Celsius. If perfected, these molecules could pack large amounts of information into tiny spaces. “Pink Floyd’...

Does cellular senescence hold secrets for healthier aging

Image
  Disease, injury, and other stress factors harm cells throughout our bodies. Ideally, the damaged cells are cleared by our immune systems through a process called apoptosis. But as we age, our bodies are no longer as effective at removing dysfunctional cells, and this can contribute to a weakened immune system and other less efficient biological processes. An increasing number of researchers are exploring whether learning to harness a cellular state known as senescence — during which damaged cells resist removal by apoptosis, linger, and harm neighboring normal cells — might hold the key to revitalizing aging tissues and increasing healthy, active years of life. Senescent cells are unique in that they eventually stop multiplying but don’t die off when they should. They instead remain and continue to release chemicals that can trigger inflammation. Like the one moldy piece of fruit that corrupts the entire bowl, a relatively small number of senescent cells can persist and spread in...
