🗞️ Driving the news: Scientists at Oregon State University have discovered a new species of electricity-conducting bacteria, named Candidatus Electrothrix yaqonensis
• Found on a brackish beach in Oregon, this bacterium displays unique morphological and genetic features that could pave the way for innovations in bioelectronics, including biodegradable devices and biosensors
🔭 The context: Cable bacteria, first identified in marine and freshwater sediments, form long filamentous structures capable of conducting electricity via internal “biological wires”
• This new species stands out for its unusually thick and spiral-patterned ridges, a novel transparent protective sheath, and genetic mosaicism combining features of saltwater and brackish water genera
• Its discovery provides critical insight into bacterial evolution and adaptation to fluctuating environments
🌍 Why it matters for the planet: The bacterium’s high conductivity and environmental resilience offer promising applications for sustainable technologies, including eco-friendly electronics and bioremediation of heavy metals and pollutants
• Harnessing biological conductivity could reduce reliance on non-biodegradable materials, aligning with circular economy goals and environmental conservation efforts
⏭️ What's next: Researchers plan further studies to understand the bacterium’s sheath formation and conductive fiber self-assembly
• Insights from Candidatus Electrothrix yaqonensis could accelerate the development of bioelectronic devices, potentially impacting environmental monitoring, clean energy technologies, and pollution remediation within the next decade
💬 One quote: "It is as if the structure itself was designed with an engineering intent," noted researchers, highlighting the bacterium’s sophisticated natural architecture
📈 One stat: The bacterium’s electrical resistance measures approximately 370 kilo-ohms — matching or exceeding the conductivity performance of previously known cable bacteria
