The secret of “Conan the Bacterium,” a microorganism that can withstand high radiation levels, has been discovered by scientists.
In addition to providing new safeguards against radiation-related hazards on Earth, this finding has the potential to completely transform astronaut safety in deep space.
There is a little marvel with superhuman skills deep within the microscopic universe.
Appropriately known as “Conan the Bacterium,” Deinococcus radiodurans is able to withstand radiation doses 28,000 times greater than those that would kill a human. Researchers have now discovered a potent antioxidant that serves as its secret weapon.
This antioxidant, a unique combination of manganese, phosphate, and a small amino acid molecule, is a protective shield against radiation. According to researchers, the combined components are much more effective than a single ingredient.
According to Proceedings of the National Academy of Sciences, these findings could have immense consequences in protecting astronauts from cosmic radiation in deep space missions.
“Understanding this combination unlocks the potential for powerful radioprotective applications,” said Brian Hoffman, a co-author of the study.
Such applications are not limited to space but may have applications in healthcare, defense, and mitigation of risks from radiation exposure on Earth.
It’s a hardy bacterium that has survived in extreme conditions, outside the International Space Station for three years, and hypothetically survives on Mars for millions of years. Inspired by these defenses, scientists developed a synthetic antioxidant called MDP, which one day might protect astronauts and humans on Earth from radiation.
With research continuing to explore this “secret sauce,” the chance for paradigm-shifting developments increases ensuring humanity and science push further into the final frontier.
