Fungal Resistance to Nuclear Radiation
😆 I was shown a study on the increased growth of fungi resistant to nuclear radiation,
and then asked to respond to it — as evolutionists have cited it as evidence of evolution,
due to the increased growth rate of fungi on the one hand,
and resistance to nuclear radiation on the other.
Anyway, I opened the study,
and as usual, the response to them was from the same study.
🧪 The Study Says:
Exposure of melanin to ionizing radiation, and possibly other forms of electromagnetic radiation,
changes its electronic properties.
- Melanized fungal cells manifested increased growth relative to non-melanized cells
after exposure to ionizing radiation,
raising intriguing questions about a potential role for melanin in energy capture and utilization.

Pigmented fungal cells showed increased growth compared to non-pigmented cells after exposure to ionizing radiation, raising interesting questions about the possible role of melanin in energy capture and utilization.”
🔬 Chemical composition and paramagnetic properties of melanin influence its interaction with ionizing radiation.
Ionizing irradiation changed the electron spin resonance (ESR) signal of melanin.
This demonstrates that melanin is the pigment that confers radiation resistance,
and that melanin plays a role in interacting with radiation.
The high-energy electrons generated by Compton scattering are ultimately responsible for the radiobiologic effects caused by gamma radiation —
either by direct interaction with DNA,
or through radiolysis of water in the cells,
a process that results in the formation of reactive short-lived free radicals capable of damaging DNA.
🪫 Stable free radicals in melanin may interact with these high-energy electrons
and prevent them from entering a cell,
thus enabling melanin to function as a radioprotector .
The Compton electrons may then undergo secondary interactions with melanin molecules,
with their energy gradually lowered by melanin.

🧠 This means:
The mutations in the gene sequence are not related to the occurrence of mutations in the original gene ,
but rather that the changes occurred due to physical properties,
which led to an increase in the reaction rate.
But is it possible to increase energy through interaction with radiation?
From the same study also:
📌 Exposure to ionizing radiation and other forms of electromagnetic radiation increases electron transfer properties of melanin.
🧪 For those who don’t know what electron transfer is — let’s briefly explain:
It’s a basic biological process that occurs to increase energy.
What does this prove?
The same study (Pasha) proves this:
Irradiation of melanin for 20 minutes increased the velocity of the NADH/ferricyanide coupled reaction 3-fold in comparison to that measured for non-irradiated melanin, while 40 min irradiation had an even larger effect, causing a 4-fold increase in velocity.
Irradiation of dead cells caused a significant increase in the XTT reduction, thus confirming our hypothesis that radiation enhances electron-transfer properties of melanin. Given that melanization is associated with reduced pore size, which could reduce passive nutrient uptake and that melanin is synthesized from highly reactive cytotoxic intermediates of the oxidation of L-Dopa, it is possible that melanization requires a higher metabolism for cell survival. In short, when the reaction rate in a biological process increases, it is intuitive that the rate of growth will increase, due to increased metabolic rates. It’s like a fan, rotating using a motor. At the same time, if the air needed for its movement is available, its rotation speed will increase to a rate greater than normal. Study:

BackgroundMelanin pigments are ubiquitous in nature. Melanized microorganisms are often the dominating species in certain extreme environments, such as soils contaminated with radionuclides, suggesting that the presence of melanin is beneficial in their life cycle.
