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.

Trace amounts of manganese is essential to human health. Now, a team of scientists from the University of Delaware, Scripps Institution of Oceanography, the University of Hawaii, and Oregon Health and Science University has found that a dissolved form of manganese, Mn(III), is important in waterways such as the Black Sea and Chesapeake Bay. It can keep toxic hydrogen sulfide (sulphide) zones in check.… Read more…
