The status of electronic waste polluting the environment is expected to change. In the near future, humans may use smaller, faster, and more degradable green computers. Shu Jianjun, a professor at Singapore's Nanyang Technological University, is trying to use human DNA to make computers. The team he led found that using human DNA to make computer chips is more environmentally friendly. It could also make computers smaller and calculate faster by 1 trillion times.
Shu Jianjun published his latest research results in Physical Review Letters. He said that the human body is like a super-large computer. When someone touches our arm, this information is quickly transmitted to our brain. Therefore, he believes that human DNA can be used to manufacture computer information. “The human body is like a computer and is counting every moment, faster than the fastest silicon-chip supercomputer. The silicon-chip computer uses binary calculations and generates a lot of heat, which is not conducive to environmental protection.â€
In addition, the DNA is very small. If it is used to make wafers, the wafers can be made smaller and lighter, but the amount of information stored is large. It is reported that one gram of DNA can store an amount of information equivalent to one trillion CDs, which is much larger than existing computer memory chips and other storage media. Another advantage is that DNA is obtained from organisms, so that after being abandoned, G can be disintegrated by nature, while silicon is not easily degraded and pollutes the environment.
Shu Jianjun ordered five tubes of human DNA from the United States to further confirm his research. Not surprisingly, when he used DNA instead of silicon to convey information, its speed became almost as fast as "light speed." Compared to traditional wafers, DNA delivered one trillion times faster.
However, the DNA computer currently only stays at the most basic stage of research. Up till now, it still needs a lot of manpower operation. In addition, the cost is also a problem. The cost of DNA is quite high and it is difficult to commercialize. Despite numerous challenges, Shu Jianjun is still happy to see the prospects of the DNA computer. He said that next, he and his team will try to use human DNA to make a wafer and put it into a computer. (Reporter Yu Wenyan)
