Es descobreix una bacteria a Helsinki que pot aprofitar residus radiactius per obtindre la seva propia energia. Redueix a dècades només el temps de vida d'aquests residus

 

In a scientific breakthrough that could redefine nuclear energy, researchers at the University of Helsinki have discovered a species of radiation-resistant bacteria capable of breaking down nuclear waste — reducing its radioactive lifespan from thousands of years to just a few decades.


These extremophile microbes, identified as a modified strain of Deinococcus radiodurans, can survive radiation levels 3,000 times higher than lethal doses for humans. Instead of dying, they use radioactive isotopes like cesium-137 and strontium-90 as an energy source, transforming them into stable, non-radioactive compounds through a process known as bioremediation.

Finland is now conducting field tests at the Onkalo nuclear repository, one of the world’s first permanent nuclear waste storage sites. If successful, this technology could shorten cleanup times from millennia to decades, making nuclear power far cleaner and safer.

This discovery shifts nuclear waste management from passive containment to active biological cleanup, offering a sustainable alternative to deep geological burial and potentially revolutionizing the future of global energy safety.

From the depths of Finland’s uranium mines comes a microscopic ally that might finally solve one of humanity’s most dangerous problems.
