This Mushroom Survives in Chernobyl… and Could Protect Us on Mars 🍄
4/10TL;DR
From ultrafast fungi and radiation-tolerant black molds to mistletoe-based adhesive, nature is offering models for new materials, shielding and industrial processes that engineers still struggle to match.
KEY POINTS
A dung fungus outpaces supercars by orders of magnitude
Among the most violent launches in biology are the spores of coprophilous fungi that grow on herbivore dung. In a 2008 study, researchers filmed species including Ascobolus immersus at up to 250,000 frames per second and found spore ejections reaching about 180,000 g. That is enough to take a particle from 0 to 100 km/h in roughly 16 millionths of a second, far beyond the acceleration claimed for any road car.
The mechanism is a microscopic water cannon
The spores are fired by what researchers liken to an osmosis water gun. Water builds up in a sac-like cell until it ruptures, expelling spores in a jet at 2 to 25 meters per second, or up to 90 km/h, with ranges reaching 2.5 meters. The pressure involved is only about 4 bar, but the extreme brevity of the release creates the enormous acceleration.
Even that is not the fastest movement in nature
The absolute acceleration record belongs not to a fungus but to the hydra, a small freshwater relative of jellyfish and coral. A 2006 study found that its harpoon-like stinging organelle fires in about 700 nanoseconds and reaches roughly 5.4 million g. The feat relies on both elastic energy stored in a collagen-like structure and internal osmotic pressure of about 150 bar.
Black fungi thrive in radioactive zones
Inside the shelter covering Chernobyl reactor 4, researchers identified 37 fungal species in 1997, many of them black and rich in melanin. One of the most notable was Cladosporium sphaerospermum. In heavily contaminated areas, such dark fungi tend to dominate, suggesting an unusual advantage in high-radiation environments.
Radiation appears to stimulate growth
Follow-up work showed some melanin-rich fungi growing toward radioactive sources, a behavior known as radiotropism. In 2007, experiments at the Albert Einstein College of Medicine exposed fungi to radiation levels around 500 times natural background, and melanin-containing strains grew faster while non-melanized strains did not. Researchers remain cautious about calling this true radiosynthesis, but the growth effect is well documented.
Melanin may also help shield radiation
In one mouse experiment, animals fed the melanin-rich mushroom known as Judas’s Ear showed an 80 percent survival rate 45 days after exposure to a lethal 9-gray dose of radiation, while mice given porcini or placebo did not survive. The result does not prove a ready-made human treatment, but it strengthens interest in melanin as a radioprotective material.
Space agencies are watching closely
A 2018 experiment on the International Space Station placed a thin layer of Cladosporium sphaerospermum over a sensor and measured about 2 percent less radiation beneath less than 2 millimeters of fungal growth. The fungus also grew about 1.2 times faster in orbit than on Earth. Researchers estimated that a 21-centimeter fungal layer, or about 9 centimeters of a mix of Martian regolith and fungal melanin, could significantly reduce surface radiation on Mars, though those figures remain theoretical.
Synthetic melanin is already being engineered
In 2021, a team at Northwestern University developed a synthetic melanin inspired by radiation-tolerant fungi. The material is porous, allows air and water through, and can trap certain nerve agents in a way comparable to charcoal. Potential uses include uniforms, gas masks and future radiation-resistant coatings.
Mistletoe berries have inspired a powerful recyclable glue
Researchers at the University of Munich reported in 2026 a biodegradable adhesive based on mistletoe viscin, combined with tannic acid and malic acid. The plant’s seeds naturally use viscin to remain attached to tree bark after passing through birds, and the lab-made version adheres to wood, steel, aluminum, glass and even Teflon. In some tests it exceeded 100 kilograms per square centimeter, rivaling chemical superglues.
The adhesive also works in extreme cold and can be reused
The mistletoe-based glue reportedly remains effective at minus 150 degrees Celsius, a temperature at which many adhesives become brittle. When heated to about 90 degrees Celsius, it softens, can be peeled away and then reattached several times. That combination of strength, biodegradability and thermal reversibility could be valuable for recycling, repair and even space applications.
CONCLUSION
Nature’s designs are still ahead of technology in critical areas including extreme acceleration, radiation resilience and reversible adhesion. The industrial challenge now is turning those biological strategies into scalable materials and devices.
