(********************************************************************************************************************** )research study group was led byProfessor(***************************************************************************************************************************************************************** )(****************************************************************************************************************************************************** )and Assistant Professor Atsuo Iida from NagoyaUniversity They believed that if electrical energy streams in a river, it may impact the cells of neighboring organisms. Cells can include DNA pieces in water, called ecological DNA. To test this, they exposed the young fish in their lab to a DNA service with a marker that shone in the light to see if the zebrafish had actually taken the DNA. Then, they presented an electrical eel and triggered it to bite a feeder to release electrical energy.
Electric Eels: Natural Agents of Genetic Change
According to Iida, electroporation is typically deemed a procedure just discovered in the lab, however he was not encouraged. “I thought electroporation might happen in nature,” he stated. “I realized that electric eels in the Amazon River could well act as a power source, organisms living in the surrounding area could act as recipient cells, and environmental DNA fragments released into the water would become foreign genes, causing genetic recombination in the surrounding organisms because of electric discharge.”

The scientists found that 5% of the larvae had markers revealing gene transfer. “This indicates that the discharge from the electric eel promoted gene transfer to the cells, even though eels have different shapes of pulse and unstable voltage compared to machines usually used in electroporation,” statedIida “Electric eels and other organisms that generate electricity could affect genetic modification in nature.”
Other research studies have actually observed a comparable phenomenon accompanying naturally happening fields, such as lightning, impacting nematodes and soil germs. Iida is really thrilled about the possibilities of electrical field research study in living organisms. He thinks these impacts are beyond what traditional knowledge can comprehend. He stated, “I believe that attempts to discover new biological phenomena based on such “unexpected” and “outside-the-box” concepts will inform the world about the intricacies of living organisms and activate advancements in the future.”
