Technology benefits mankind. Watt invented the steam engine.
It is not difficult to suppress cancer.
At the recent academic conference on environment and cancer of Shanghai Science and Technology Forum in 2000, Shen, president of Shanghai Anti-cancer Association, and other famous experts at home and abroad pointed out that cancer can be suppressed as long as we start with improving the environment and changing unhealthy lifestyles.
Experts pointed out that although the cause of tumor is still unclear, scholars at home and abroad believe that 80-90% of the cause is related to environmental factors and is the result of the joint action of many factors. Among them, 35%-40% of cancers are related to unscientific and unreasonable diet, such as food pollution, and the lack, excess or imbalance of certain nutrients are related to the occurrence of tumors. In addition, 30% of cancers are caused by smoking.
Ceramics can be burned by microwave.
Japanese scientific research institutions have developed a new technology of microwave firing ceramics, which can shorten the firing time and thus reduce energy consumption.
According to the information provided by Gifu Ceramic Research Institute, which participated in the development of this technology, the characteristic of the new technology is that the ceramic body absorbs the microwave with the frequency of 2.45 MHz, and then it is fired into ceramic products by the heat emitted by itself. The special furnace using this method has been successfully developed, and the furnace wall is of double-layer structure, consisting of wave-absorbing ceramics and thermal insulation materials.

1. Cloning Technology and Genetic Breeding
In agriculture, people have cultivated a large number of high-quality and high-yield varieties with drought resistance, lodging resistance and pest resistance by using "cloning" technology, which has greatly increased grain output. In this regard, China has entered the forefront of the world's most advanced.
2. Cloning technology and protection of endangered species
Cloning technology is the gospel of protecting species, especially rare and endangered species, and has great application prospects. From a biological point of view, this is also one of the most valuable places of cloning technology.
3. Cloning technology and medicine
At present, doctors can transplant almost all human organs and tissues. But as far as science and technology are concerned, rejection in organ transplantation is still the most troublesome thing. The reason of rejection is tissue incompatibility, which leads to poor compatibility. If the organs of "clones" are provided to "primitive people" for organ transplantation, there is no need to worry about rejection at all, because the genes and tissues of the two are compatible. The question is, is it legal to use "human cloning"? Is it economical?
Cloning technology can also be used to multiply valuable genes. For example, in medicine, it is through "cloning" technology that people produce insulin for treating diabetes, growth hormone for dwarfism patients to grow taller again, drynaria for resisting various viral infections, and so on.
