Sulfide-sensing mechanisms in purple bacteria

Recent evidence demonstrates that the origins of photosynthesis can be found in deep sea hydrothermal vents, where microbes evolved to obtain energy from ejected hydrogen sulfide and methane gases. These microbes are capable ...

Researchers build bacteria's photosynthetic engine

Nearly all life on Earth depends on photosynthesis, the conversion of light energy into chemical energy. Oxygen-producing plants and cyanobacteria perfected this process 2.7 billion years ago. But the first photosynthetic ...

Lab-made complexes are 'sun sponges'

In diagrams it looks like a confection of self-curling ribbon with bits of bling hung off the ribbon here and there. In fact it is a carefully designed ring of proteins with attached pigments that self-assembles into a structure ...

Purple bacteria on earth could survive alien light

Purple bacteria contain pigments that allow them to use sunlight as their source of energy, hence their color. Small as they are, these microbes can teach us a lot about life on Earth, because they have been around longer ...

Researchers recreate photosynthesis to power devices

Nature has perfected the art of using the Sun to fuel growth. A team of international researchers looked into what is needed to recreate the process artificially. The results could have various uses, from an alternative to ...

Team provides new insight into photosynthesis

Pigments found in plants and purple bacteria employed to provide protection from sun damage do more than just that. Researchers from the University of Toronto and University of Glasgow have found that they also help to harvest ...
