WEST LAFAYETTE, Ind. – A delicate balance of electrons flowing through the photosynthetic machinery is essential to a plant’s ability to turn sunlight into energy and its survival. Understanding the ...

Microbial reduction of ferric iron [Fe(III)] is an important biogeochemical process in anoxic aquifers. Depending on groundwater pH, dissimilatory metal-reducing bacteria can also respire alternative ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

A group of researchers in Japan has revealed, for the first time, a mechanism for controlling the potential of an “electron carrier” protein in the redox reaction that all organisms need to obtain ...

Scientists know that a particular protein is responsible for regulating gene expression of photosystems in response to perturbations in photosynthetic electron flow, but how it senses the electrons ...

The hydrogen atoms of [4Fe-4S] type ferredoxin, one of the electron carriers, have been visualized and both experiments and calculations have revealed the mechanisms that control the redox potential.
