A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. The ability of computers to follow a sequence of operations called a program, make computers very applicable to a wide range of tasks.Sometimes, it is said that computers are artificial brain operating by the human brain. Cells can be referred as smallest computers operating inside a human body. They receive and send information according to their function.(Also Read: Get iPhone at Just Rs 1,000 And Other Latest Smartphones In As Low As Just Rs 84)
But cellular computing is more than just a convenient analogy. In the last few years, Bio-technical scientists have been working to hack the cells’ algorithm program in order to control their functions. It’s more like a role as Bio-software engineer, gradually corrupting a cell’s algorithm programming—its DNA—over years. In a paper published today in Nature Biotechnology, researchers programmed human cells to obey 109 different sets of logical instructions. After more research, this could result in cells capable of responding to specific directions or environmental cues in order to fight disease or manufacture important chemicals. This could bring a drastic change in the field of medicine. We could easily instruct a cell to perform several tasks required for the disease or abnormality in the body.(Also Read:Most awaited phone ever: Motorola G5 Plus review, specs, price, features and more)
How is programming possible for the Human cell?
A cell could be reprogrammed, by the use of simple NOT logic gate. This is one of the simplest logic instructions: Do NOT transmit if you receive a trigger. This study’s authors used this function to create cells that light up on command. Biologist Wilson Wong of Boston University, who led the research, refers to these reprogrammed engineered cells as “genetic circuits.”
Whenever the cell did contain a specific DNA recombinase protein, it would NOT release a blue fluorescent protein that made it light up. But when the cell did not contain the enzyme, its instruction was DO light up. The cell could also follow much more complicated instructions, like lighting up under longer sets of conditions.
