A blue pigment found to be a high-performance ammonia adsorbent

Akira Takahashi (Researcher) and institutional collaborators have discovered that the blue pigment Prussian blue has a higher adsorption capacity than common ammonia adsorbents, and controlled the structure of Prussian blue ...

Green beer highlights the science behind the brew

Working with Scottish Bioenergy, the team found that by limiting all other wavelengths, the algae – known more commonly as Spirulina – will start to mass-produce the blue pigment when exposed to long wavelength red light.

Viruses cause bacteria to produce pink pigments

Plants use certain colour pigments in order to convert light into energy by way of photosynthesis. They allow plants to gather light energy. This also works in a similar way for microbes, for instance cyanobacteria. The fact ...
