Sunlight could be used to power lasers

Sunlight, one of the planet's most abundant sources of renewable energy, could be used to power lasers, according to a study from Heriot-Watt University.

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 ...
