What should we look for when trying to find life beyond Earth? Should it be the familiar green and blue colors that we see thriving on our small, blue planet, or something else entirely? This is what ...

Purple sulfur bacteria (PSB) convert light energy into chemical energy through photosynthesis. Interestingly, certain species can photosynthesize even in environments with low-calcium levels. Using ...

Researchers have investigated the structure and light energy transfer efficiency of a protein complex crucial to the photosynthesis of purple sulfur bacteria thriving in high-salt, high-alkaline ...
