Human living cells as the core
Computers are electronic devices that people often use in their daily lives. They are found in almost every family. But have you seen a biocomputer that is only cell-sized and capable of handling large amounts of information like an electronic computer? Recently, scientists have created biological computers consisting of only 9 human living cells. Don’t underestimate these 9 cells, they are the core of this bio-computer.
Some scientists have developed a simple biological computer transformed from two kidney cells. Because the cell type is the same, it can only react to the presence or absence of a certain substance. The type and concentration of the substance in the human body can only be “heart”. There is not enough energy.”
This bio-computer consisting of 9 cells is different. Although it is about the size of a simple bio-computer transformed into a kidney cell, its performance is much better than its power, such as its powerful information processing capabilities.
The nine cells of this bio-computer are different human living cells. It brings together the ability of these nine cells to respond to substances, so it can handle many kinds of substances, and can also feel small changes in these substances. Sensitive. Every cell can receive information, process information and output information, and can also transfer information to each other, which reminds people of the information processing process of the computer.
“stealing” digital computer
In a digital computer, the encoded information is input to the computer through an input device, such as a keyboard, and the information flows in the circuit. When the host arrives at the host, the host processes the information, and the processed information passes through the circuit to the output device such as the display. At this point, we will see the output of words, numbers, etc. on the display.
The biological computer has no circuit, and there is no input device such as a keyboard. The special protein and the like in the human body can be directly input into the biological computer. They send information such as their own type and concentration directly to the “host” cells, which process the cells and release the corresponding pheromones. The pheromones are passed directly to the next cell, and then the other cells are processed again. and many more.
An example of the presence or absence of iodine content in the human body and the presence or absence of thyroid hormone. Iodine is an important raw material for the synthesis of thyroid hormone. In general, iodine is high and thyroid hormone is synthesized much more.
When the concentration of iodine is high, cells that process iodine release a “high concentration of iodine” pheromone, which is then passed to cells that process thyroid hormone. If the cell receives a “high concentration of iodine” pheromone and receives information that the concentration of thyroid hormone has not changed, the cell will release a pheromone after processing the two inputs. This pheromone informs the human body: “You The body has a problem!” If you receive a high iodine content, and receive information that the thyroid hormone is also increasing, this cell will also release a pheromone, but this pheromone will be “silent” and will not remind us.
Although there are many differences between biological computers and digital computers, both follow the input-processing-output program, except that the biological computer inputs the biological material, the processor is the cell, and the output is the pheromone. In addition, such a computer can only be implanted in the human body and cannot be used alone outside the human body.
