Production of gold through bacteria
Some metals, like iron, are very good for the growth of some bacteria, but others, like gold or silver, have an opposite effect, that is, they can be said to be bactericidal.
It has recently been discovered that the bacterium Cupriavidus metallidurans, known to scientists, produces molecular gold between its cells to protect itself from the gold ion. According to an article published by researchers from the University of McMaster (Ontario, Canada) in the journal Nature Chemical Biology, the bacterium Delftia acidovorans produces molecular gold around it from the gold ion and in a neutral solution. The finding is of great importance in the nanoparticle industry, as the process is only a few seconds. In these seconds it can have a gold sheet that can be used in different industrial processes.
This weekend I've been thinking about the word 'aesthetic' in relation to a phrase said by a friend: “This work is aesthetic.” I have studied the etymology of the word aesthetic, it seems that its meaning was originally perceived through the senses, and it was later associated... [+]
