Achievements in the development of modern biological sciences 20

What scientific achievements have Chinese biologists made in the past two years?

China's achievements in biology in recent years mainly include the following four aspects:

Clause. First, the original innovation ability of biotechnology has been rapidly improved. The level of academic ** is rapidly improving.

During the "Tenth Five-Year Plan" period, Chinese scientists in the field of biology published more than 30 articles in top international academic journals such as Nature, Science and Cell. In particular, Chinese scientists broke the embarrassing silence of not publishing in the journal Cell for more than 20 years, and published five articles in a row in 2005 alone.

Clause. Second, the development of agriculture is strongly supported by biotechnology. In the past five years, China has bred a total of 60 approved super hybrid rice combinations, of which 7 new combinations have reached 800 kg per mu. A total of more than 1.5 billion mu of super hybrid rice has been promoted, and the cumulative increase in rice yield is 7.5 million tons based on the calculation of an increase of 50 kg of rice per mu.

Clause. Third, the situation of insufficient innovation in the pharmaceutical industry has initially changed. Driven by the National 863 Program, the level of China's biopharmaceutical industry has been greatly improved in recent years

45 innovative drugs with independent intellectual property rights have been approved for marketing, 41 new drug certificates are being declared, 109 drugs have been approved to enter clinical trials, and 206 innovative drug candidates are about to complete laboratory research.

Clause. Fourth, China's biochips appeared in the international market. According to the Ministry of Science and Technology, in recent years, China has established five biochip R&D and industrialization bases in Beijing, Shanghai, Shaanxi, Tianjin, and Nanjing, and initially formed a biochip R&D pattern with the five bases as the core.

After five years of vigorous cultivation, an emerging industry with high technological content and added value of products, the biochip industry, has begun to take shape in China, and some products have begun to enter the international market.

Biology, abbreviated as biology, is one of the six basic disciplines of natural sciences. Taxonomy is the branch of biology that studies the methods and principles of taxonomy. In the 20th century, especially since the 40s, biology has absorbed the achievements of mathematics, physics and chemistry, and gradually developed into a precise, quantitative, and in-depth molecular science.

The basic unit of life is the cell, which is a material system composed of proteins, nucleic acids, lipids, and other biological macromolecules. Life has many properties that inanimate matter does not have.

Taxonomy is the branch of biology that studies the methods and principles of taxonomy. Taxonomy is the naming and hierarchical division of various groups of organisms according to taxonomic principles and methods. After the Swedish biologist Linnaeus named the organisms, later biologists classified them by domains, kingdoms, phyla, classes, orders, families, genera, and species.

The development of biology has always been a constant research for many of our scientists, and there have been many major breakthroughs in the development of biology in the past decade. Next, I will introduce it to you. <>

In recent years, there is also a very interesting question that has been answered, that is, how the protein is folded, in fact, this problem may be confusing for many people who do not understand biology, but this is a problem that took many years to develop, it can be said that it took a lot of energy and physical strength of R & D personnel, many scientists even think that this may be a problem that cannot be solved in a lifetime, but we have successfully solved this problem through artificial intelligence programs. It can be said that artificial intelligence itself was also invented by us humans, so we have successfully solved this problem through our own wisdom and using machines. <>

And the biggest breakthrough development in biology recently, I think is to develop a vaccine at a very fast speed, in fact, this is also an invention related to the life safety of all mankind, because in the past, in fact, our fastest vaccine research and development record was also four years, but in 2020, a very serious outbreak of the new crown epidemic, we worked hard for 11 months, and we developed a new crown vaccine, which can be said to be very powerful! And this speed is also very fast, far exceeding the previous record, to be able to develop a vaccine in such a fast time, not only a biological breakthrough, but also to be able to make progress and development together for all mankind, and continue to be sustainable, which has made a great promotion, after all, this new crown vaccine is of great significance to all mankind. And the invention of this new crown vaccine is equivalent to a timely rain, which makes many people very excited.

Biology is actually constantly improving, and it is also constantly benefiting mankind, allowing us to enjoy the development of biology, and also allowing us biologists to go further.

Compared with the development of physics and biology, the development of chemistry as an independent first-level discipline seems to rely heavily on the intersection of physics and biology. Two relatively new fields: the development of computational chemistry is now heavily dependent on the improvement of computer computing speed, and biochemistry is booming, but the speed of industrialization is not obvious.

Moreover, organic chemistry is the largest application, and the research and development speed of chemical drugs in the pharmaceutical industry has slowed down, and there is a tendency to be overtaken by biological drugs. So ask about the development of chemistry in recent years (ten years), and possible breakthroughs in the future.

China's major breakthroughs in biology, including the exploration of the moon and other celestial bodies in the solar system, the establishment of a space station, the development of a very major breakthrough in medical treatment, and the development of a lot of drugs, these are all breakthroughs in biology in our country.

At present, basic science has developed to a very stable period, biochemistry is developing vigorously, but the speed of industrialization is not obvious, the research of chemical and pharmaceutical industry has slowed down, and there is a tendency to be caught up and surpassed by biology.

The mystery of locust swarming: 4-vinylanisole is a swarming pheromone of locusts, the analysis of the three-dimensional structure of the first new coronavirus protein and the discovery of two clinical drug candidates, the mechanism and regulation of organ aging, the construction of animal models of new coronary pneumonia, the key cells and regulatory networks of human brain development, the discovery of brain-spleen neural pathways that regulate antibody immunity by behavior, the mechanism of eating-induced cholesterol synthesis and the discovery of new lipid-lowering drug targets, and the new mechanism of improving the nitrogen use efficiency of green revolution crop varieties, Cloning, mechanism analysis and breeding utilization of gibberella resistance gene FHB7 in wheat, antigen receptor signal transduction mechanism and its application in CAR-T**.

There has been a great breakthrough, and IPS has been developed, and some drugs have also been developed for Alzheimer's disease, and then many vaccines have also been developed, such as the new crown vaccine and HPV vaccine.

With new research, new data, and a lot of technology, a lot of problems solved, and new developments, and a lot of awards.

The achievements include genetic engineering, cloning technology, etc.

Genetic engineering: also known as gene splicing technology and DNA recombination technology, is based on molecular genetics as the theoretical basis, with the modern methods of molecular leugold biology and microbiology as a means, the different genes according to the pre-designed blueprint, in vitro to construct hybrid DNA molecules, and then introduce into living cells to change the original genetic characteristics of organisms, obtain new varieties, and produce new products. Clone:

The process of using biotechnology to produce offspring from asexual reproduction that is identical to the original individual. Scientists call the process of artificial genetic manipulation of animal reproduction cloning, this biotechnology is called cloning technology, and the meaning of Jingpiyan is asexual reproduction. Cloning technology is known as biomagnification technology in modern biology.

Summary. Hello Kiss is happy to answer for you: living things are very closely related to many aspects of human life.

Biology, as a basic science, has traditionally been the foundation of agronomy and medicine, involving cropping, animal husbandry, fishery, medicine, pharmaceuticals, health and so on. With the continuous development of biological theories and methods, its application fields are constantly expanding. Now, the influence of biology has gone beyond the traditional fields mentioned above to extend to food, chemical industry, environmental protection, energy and metallurgical industry, etc.

If biomimicry is taken into account, it also affects electronics and information technology.

Trouble a little faster.

Population, food, environment, and energy issues are global issues that are attracting worldwide attention. Currently, the world's population is growing at a rate of about 20 per year, doubling approximately every 35 years.

The population of the planet is surging at an unprecedented rate. The population problem is as much a social problem as it is an ecological one. People must conduct a thorough and quantitative study of the intricate relationship between human beings and the environment in order to have a clear understanding of the earth and the fate of mankind, so that they can learn to control themselves violently and skillfully, so that the population can be maintained at a reasonable number.

Biology should and can make its own contribution in this regard. Achievements in endocrinology and reproductive biology led to the invention of the oral contraceptive, which has contributed to the worldwide spread of family planning. In the population problem, in addition to the surge in numbers, genetic diseases also pose a serious threat to the quality of the population.

Some data suggest that the proportion of newborns with various genetic disorders is between 3. In some mountainous areas of China, the proportion of mentally imperfect people is 2 3, and in some areas it is more than 10. Uncovering the causes of genetic diseases and finding ways to control and conquer genetic diseases is undoubtedly another important task of biology.

At present, a pedigree analysis is carried out to determine whether the patient has a genetic disease, and useful genetic guidance and advice is provided to the patient; Chromosomal analysis and biochemical analysis of various enzymes are performed on the desquamation cells of the fetus to diagnose whether the future baby has a congenital genetic disorder. These methods can avoid or reduce the birth of babies with genetic diseases, thereby reducing the heavy burden on families and society. The application of genetic engineering to genetic diseases is called genetics, and some progress has been made in experimental animals on the genes transmitted by several posthumous grandchildren.

With the development of genetic engineering technology, genetics will open up broad prospects for the control and control of human genetic diseases.
