Abstract： The marine area is a strategic area of China. To build China into a strong maritime country, we should enhance the capacity for exploiting marine resources, develop the maritime economy, protect the marine ecological environment, and resolutely safeguard national maritime rights and interests. Promoting marine science and technology to achieve high-level scientific and technological self-reliance is an inevitable requirement for accelerating the construction of maritime country. The marine scientific observation and exploration is the basic means of understanding the ocean, and is also an important basis for the marine resources development, environmental protection and rights and interests protection. This paper reviews the important progresses of global and national ocean observation and exploration program and network, with a view to highlight the practice of ocean scientific observation and exploration technology system construction in Chinese Academy of Sciences, and puts forward thoughts and suggestions on next steps. To build up China’s strength in ocean scientific observation and exploration technology system, we should further strengthen the top-level design to drive the “twin engines” of national strategic needs and frontier trends in science and technology, redouble efforts on developing scientific and technological breakthroughs to make continued efforts to solve the most urgent key problems, and innovate improve institutions and mechanisms to make full use of China’s strategic science and technology capabilities in the marine field, so as to provide strong scientific and technological support for the construction of China as a maritime power.

Abstract： Tuberculosis (TB), a chronic communicable disease caused by the pathogen Mycobacterium tuberculosis, has harassed the human being for long-term and remains to be one of the major public health problems facing the world as well as the leading cause of death from a single infectious agent. We are falling short of TB control targets set by the World Health Organization (WHO) and United Nations (UN). To achieve the ambitious targets of global TB prevention and control, there is an urgent need for immediate action as well as science and technology breakthroughs (e.g., a new vaccine and drug) to rapidly reduce TB incidence worldwide. This study summarizes the current progress on global and China’s TB prevention and control, and analyzes the contribution of science and technology in TB prevention and control. Based on the above analysis, we propose the following thought and advice on strengthening TB prevention and control through science and technology: Strengthening the basic research of TB, developing new TB vaccines and drugs, developing new diagnostic techniques for TB, and perfecting the system to support and strengthen the safeguard measures. The purpose of this study is to promote the policy layout and practice innovation of scientific prevention and control of TB in China, thus speeding up the realization of goals set by the WHO End TB Strategy.

Abstract： As an important means to achieve the goal of carbon neutralization, hydrogen energy has attracted global attention. As the United States has more than 30 years of practical experience in hydrogen energy R&D and application, this study conducts a detailed investigation on the hydrogen energy development plan and strategy formulated by the U.S. government, analyzes the U.S. hydrogen energy strategy and development objectives, direction and achievements since 1990, and focuses on the latest U.S. hydrogen energy development strategy in 2020 and the hydrogen energy breakthrough plan in 2021. It is concluded that the current US government has moved from initially establishing hydrogen energy technology reserves and promoting the application of hydrogen fuel cells in the transportation industry to accelerating the R&D and commercialization of the low-cost whole chain of hydrogen energy, especially green hydrogen technology under the goal of carbon neutralization, with diversified goals such as realizing the goal of carbon neutralization, establishing and developing hydrogen economy, and occupying a leading position in the global hydrogen energy technology and market. At the same time, the United States has relatively mature R&D and demonstration experience in electrolytic water technology. In the future, it will develop in the direction of megawatt scale and clean hydrogen production from renewable energy such as solar energy and nuclear energy. Based on such analysis, it is suggested that China should strengthen top-level design of hydrogen energy development, tackle key problems and breaking through core technologies of hydrogen energy, establish the development model of the

Abstract： Soybean is one of the most economically important leguminous seed crops that provide the majority of plant proteins, and more than a quarter of the world’s food and animal feed. At present, the soybean breeding technology in China mainly relys on conventional breeding, and the levels of both fundamental study and production lag behind those of the United States. Supported by “Innovative System of Designer Breeding by Molecular Modules”, one of the strategic priority research programs of Chinese Academy of Sciences, Chinese soybean scientists have dissected several important molecular modules controlling yield and seed quality, revealed the coupling mechanisms of diverse molecular modules, bred a series of designer soybean varieties for field tests or regional trials, which together to establish the first-generation molecular module-based designer breeding systems in soybean. In the future, we should continue to strengthen germplasm resources evaluation and exploitation system, promote autonomy public database building, improve the data sharing mechanism, vigorously develop breakthrough technologies for high and stable yield soybean and for soybean replacement feed crops, speed up the molecular design breeding and artificial intelligence breeding systems, cultivate breakthrough soybean varieties, develop green and efficient cultivation techniques. With these studies, it is expected to enhance the soybeans production capacity and relieve soybean demand gap in China.
