Cyborg bacteria convert CO2 into acetic acid
A BBC report on the August 2017 American Chemical Society meeting states ‘Cyborg’ bacteria deliver green fuel source from sunlight. To summarise, some bacteria deal with heavy metals such as cadmium by converting it to cadmium sulphide semiconductor crystals on their surfaces. These bacteria are then able to convert carbon dioxide + water + light into acetic acid with high efficiency.

On the Spectrum of Elementary Silicon
A link to this article is here for historical interest. The paper is by Sir William Crookes and was published in 1914. It concerns efforts to record spectroscopic data of pure elemental silicon.1 One difficulty concerned finding a pure sample.
