Release date: 2015-11-10 According to foreign media reports, a computer programmer in the sci-fi movie "Machine Ji" loves robots. This episode is incredible. It is considered that the future robots will be advanced and cannot replace real human couples. Currently, the latest study shows that humans can potentially have feelings with robots, even if robots have no emotions for humans. Previous expert research analysis warned that human beings can form unhealthy relationships with robots and even fall in love. The researchers asked the testers to see the painful conditions of the human and bionic robot hands (such as the hand being cut), and then studied and analyzed the tester's emotional response, and finally reached the conclusion of the study. They analyzed the tester's brain electrical signals and found that the testers produced similar real-time sympathy for humans and robots. The study was completed by researchers at Toyohashi University of Technology and Kyoto University in Japan, and for the first time provided neurophysiological evidence that humans have emotional relationships with robots. The results of the study show that we can generate feelings with bionic robots, which is similar to the feelings between humans. At the same time, scientists emphasize that we cannot fully understand robots because their bodies and consciousness are different from humans. Research author and colleague Michiteru Kitazaki said: "I believe that the future society will be a harmonious relationship between humans and robots, provided that both humans and robots abide by social moral principles. Producing 'true feelings' to robots may promote altruistic behavior, robots can help us or Interactions with humans." At present, experts have begun to worry about human feelings about robots. In October this year, a senior robotic ethicist warned that "sex robots" would seriously damage the relationship between human lovers. Dr. Kathleen Richardson, a robotic ethicist at De Montfort University in the United Kingdom, said in an interview that bionic robot technology is "unnecessary and unpopular." Sex robots have become the focus of the robot industry, and designers have studied the role of sex robots and played roles. At the same time, Kathleen believes that the emergence of sex robots will not be conducive to the relationship between men and women, adults and children, men and men, women and women. The future "sex robot" created by the artist César Vonc Experts warn that the intimacy between humans and robots will become commonplace. But Dr. Helen Driscoll, a sex psychologist, points out that when humans recognize robots as their close partners, our material relationships will become more primitive and simple in the near future. At present, online inflatable dolls can be customized on the Internet. The rapid development of such technologies will make these products more realistic and close to real human partners. The emergence of future sex robots will seriously affect the feelings of real couples. When a real couple sees a sexual encounter with a robot, it will have an aversion to rejection. When people spend a lot of time in virtual reality and online networks, they will bring more mental health problems. Lack of contact with humans is harmful because human beings are social animals, and isolation from life can create mental health problems. Recent studies have shown that young Japanese residents have begun to reject real life and intimacy with couples, and half of adult Japanese say they no longer have sex with their loved ones.

It provides a way to make more copies of a portion of DNA.
We need to have PCR ingredients that include DNA portion, Buffer solution, Primer+DNA (tap polymerase), and Nucleotides during the preparation step.
In the step of PCR sequence, there are three steps in this section.
Step 1 Denaturation
The addition of heat is needed to separate the two strands of the DNA molecule.
Step 2 Annealing
Temperature, is going to be cool in this step, should allow the primers to bind to the specific segments.
Step 3 DNA Synthesis
To make more copies of the DNA.
Those three steps above keep repeating to make enough copies of the DNA fragments. It is the principle of how PCR machine works.
