Cells performing calculator jobs
Engineers at MIT in the United States have turned bacterial cells into calculators that allow the calculation of sums, breaks, divisions, square roots or logarithms.
To make the sum, for example, two circuits are prepared, each of which is activated with a specific molecule. In the first circuit, sugar called arabinosa activates the gene that generates the GFP protein. In the second circuit, the AHL molecule also produces the gene that generates the GFP protein. The total GFP will tell us the exact sum of the amounts of arabinous and AHL.
The main applications of these research papers can be therapeutic. For example, it is believed that with this system, cells could be created to detect and attack tumor cells. However, these bioengineering tests have risks, such as the unexpected occurrence of harmful pathogens.
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... [+]
Life surrounds everything, it is limited and fragile. To live good lives, it seems to me that the body knows what to do, while the mind, although it knows (when it is well informed), often sees the body deliberately silence. In this silence the mind opens itself to relations... [+]
The consumerist culture we live in sends every user to an unreasonable enjoyment. As Slavoj Zize says, Enjoy your fetish, it has become the rude mandate of hypermodernity. Current enjoyment is carried out through existing technological devices to occupy the place of fetish. But... [+]
In 2018, I leveraged social media and most communications from devices to try to control where I focus on life. Every day I go on that task, in the light of the moth, because my curiosity is constantly looking for fresh information to help me understand reality. At that time I... [+]
