Controlled Substrate Crossover from Cathode to Anode for Long-Term Autonomous Operation of Microbial Fuel Cells: A Transport-Reaction Modeling Study

Microbial fuel cells (MFCs) have been widely investigated as decentralized bioelectrochemical systems capable of converting organic substrates into electricity. However, their long-term autonomous operation is constrained by substrate depletion in the anode compartment, leading to metabolic starvation of electroactive biofilms and a decline in power output. Conventional MFC design treats…

Flightless beetles evolved distinct snail-hunting shapes on Japan's largest island

Islands are widely recognized as natural laboratories of evolution. The ocean restricts movement among islands, allowing isolated populations to adapt to different environments and, at times, diverge into new species.

Scientists map the microscopic roots of chaos in dusty plasma using supercomputer simulations

Research Matters Staff Writer(s) Jammu 17 Aug 2026 Researchers have achieved a breakthrough in understanding the chaotic world of turbulence by tracking the movement of millions of individual particles in a specialised state of matter known as dusty plasma.

Scientists map microscopic origins of turbulence in dusty plasma using supercomputer simulations.
Understanding dusty plasma turbulence could improve plasma containment in nuclear fusion reactors.
