People shine in a visible light that disappears into death, study states

Life glows gently in its calmest moments – so subtle that it is invisible to your eyes, but bright enough so that science can recognize. Recently, researchers from the University of Calgary and the National Research Council of Canada have known this mysterious biological glow, scientifically as Ultraweak photon emission (UPE).

Her groundbreaking experiments not only showed that life releases tiny amounts of light, but also how this glow fades after death and emphasizes its potential as an innovative instrument for understanding health, stress and vitality.

Bright proof of life

Ultraweak photon emission or biophotonal emissions refers to very weak light that is produced by all living organisms – from plants and bacteria to humans. This emission is extremely subtle and comprises only 10 to 1,000 photons per square centimeter every second.

For comparison, a common light bulb releases billions to billions of photons per second. Daniel Oblak, Associate Professor at the University of Calgary, makes it clear: “We metabolize; we give light. This implies nothing other than we produce energy.”

Although the biophotone emissions have fascinated the scientists for decades, its precise origin and its purpose remains somewhat difficult to grasp. Scientists generally believe that this glow results from chemical reactions in cells – especially with molecules that are referred to as reactive oxygen species (ROS). These molecules form naturally in metabolic processes, especially under stress or injury. When Ros interact with proteins or fats in cells, the electrons shift and ensure tiny light outbursts.

Record the subtle glowing of life

In order to clearly examine the biophotonal emission, the researchers used a highly progressive imaging technology. Electron-multifecating load-packed devices (EMCCD) and CCD cameras (charge-coupled devices), which can record individual photons, were used to observe living and dead mice as well as plant leaves under strictly controlled conditions. This approach eliminated disorders from environmental light or heat.

In her study, which was published online in the Journal of Physical Chemistry Letters, four living mice were originally placed in complete darkness. Her weak glow was carefully recorded for an hour. After euthanasia, imaging took another hour and kept the body temperature of the animals constant.

The results were strong: During the life of life, more photons are significantly emitted, mainly out of their skin than after death after death. According to the researcher Vahid Salari, after death, “some organs still emit light, most likely out of the liver”, although this was less than 10 percent of the total emission that was observed in life.

Plants illuminate under stress

Similarly convincing results emerged from studies in which plants were involved. The researchers tested leaves of Thale Cress and dwarf rain shields and are subject to physical injuries and chemical treatments. In comparison to untouched regions, injured areas consistently emitted lighter biophotone signals.

Remarkably, when Benzocain – a common anesthesia – was applied to injured leaves, observed the most intense biophotonal emissions that even exceeded the hydrogen peroxide produced by Ros.

This unexpected finding suggests that benzocaine interacts in unique and but unclear ways with cellular processes. Salari states: “We still don't know the main source. We have some speculations such as a sodium channel or the release of reactive oxygen species.”

Beyond body heat

A common misunderstander who dealt with researchers was whether this luminaire simply represented body heat. Oblak made it clear that body heat, which is known as black -body radiation, mainly spends infrared light – very different from UPE. The photons of this study mainly fell into the visible area and clearly differentiated them from ordinary thermal radiation.

Future potential in medicine and agriculture

Although the biophoton emission research is in the early stages, the results promise an enormous promise. Since UPE correlates with metabolic and oxidative processes, it could serve as a non-invasive instrument to recognize early illnesses, including diseases such as skin cancer. In addition, it can help to evaluate the health of transplant organs before the operation and possibly improve the results for patients.

The agricultural implications are also exciting. Farmers could soon use drones that are equipped with photon detection cameras to monitor the health of the plants. Due to the early detection of stressed plants through their emitted photons, agricultural management could become more precise and effective. Riskin shows: “It is completely plausible that drones fly over fields that measure the health of the plants.”

Research into death and vitality

Despite the scary nature of observing the subtle glow of life after death, the researchers emphasize that these results are not supernatural. Oblak calms down: “There are many metaphysical connotations to glow, but it is not an energy field around us – it's biochemistry.”

Understanding the biophotone emission can redefine how scientists and medical experts measure health and vitality. The authors of the study are optimistic but careful and indicate that there are significant examinations before practical applications are widespread.

“Now that we know there is a signal,” notes Riskin, “we can create technologies to listen to this signal.” The glow of life, once a fringe new gierde, can soon shed light on our understanding of biological health in an unprecedented way.
