    This paper focuses on the latest progress of oil generation, storage, production and engineering transformation of Gulong shale oil in Songliao Basin and holds that the high oil generation and low hydrocarbon expulsion efficiency of Gulong shale provides important material basis for oil production. The micro-nano pore and fracture combination system widely developed in Gulong shale provides the spatial basis for shale oil reservoir. In terms of engineering transformation, engineering technologies such as increasing the proportion of guanidine adhesive fracturing fluid, using silt slug to plug micro-fractures near the well, reducing the number of clusters in the section, increasing the construction displacement, and using stress interference in a positive way are proposed to realize the joint network concept of "controlling near and expanding far" and improve the scale and degree of transformation. By quantifying the process and sequence of energy release through hydraulic elastic flooding, rock and fluid elastic flooding, and dissolved gas flooding, reasonable control of pressure and orderly release of elastic energy can be achieved to control the decline of volume development. Although the revolutionary transformation of continental facies shale oil from "oil generation" to "oil production" still faces major challenges in theoretical mechanism, the engineering technologies and benefit development, continental facies shale oilin a huge scale is one of the important goals to ensure national energy security in the future.

    The discovery of bilayer nickelate superconductor La3Ni2O7 under high pressure has attracted worldwide attention, in which theoretical research plays a vital role. So far, theoretical calculations show that the two eg Ni 3dx2-y2 and 3dz2 orbitals in La3Ni2O7 are crucial to the formation of superconductivity, while the O2 p orbital also appears on the Fermi surface. Multi-orbital models have been proposed based on the above analysis. Various calculations show that La3Ni2O7 has a s± wave pairing symmetry although other pairing symmetries can be obtained. Theoretical calculations shows that the superconducting mechanism is unconventional and closely related to antiferromagnetic fluctuation. The vacancy of apical oxygen has a significant impact on the occurrence of superconductivity. The discovery of trilayer nickelate superconductor La4Ni3O10 under pressure has further enriched the family of nickelate superconductors. And its electronic band structure, multi-orbital model, superconducting pairing symmetry and so on have been investigated and explored theoretically.

    China's food security governance has been evolving in line with the goal of food security. At present, a food production pattern with new type of agricultural operating entities as its core and green production as the means has been gradually formed. Adapting to the changing governance goals through self-innovation, with an increasing number of participating entities and a growing diversity of governance tools, China's grain security governance system can effectively ensure food security. However, to realize the modernization of the food security governance system and capacity, a series of challenges need to be addressed, including the bottleneck of food production due to resource constraints, continuous impact on food security by climate change and international environment, low comparative benefits of food production, the abandonment of cultivated land, persistent non-grain production or non-agricultural use of cultivated land, and lagged application and promotion of agricultural technology. It is necessary to develop smart agriculture to improve resource utilization efficiency, strengthen infrastructure construction to mitigate the impacts of climate change, advance the international cooperation to alleviate pressure on the food system, promote high-standard farmland to improve land productivity, and optimize the agricultural technology promotion system to enhance technological efficiency.

    In the 21st century, the application of hydrogen energy and development of hydrogen energy industry have received extensive attention from the society. From the history of the Earth formation and geophysical data, the Earth's interior is a hydrogen energy reservoir. Data from Continental Science drilling suggest that large earthquakes may generate seismic waves that surround the globe and move fracture zones in the Earth's crust and mantle to release gas from the Earth's interior. After earthquakes, the Earth can release gases such as hydrogen, helium and methane, which will rush up through the mantle fracture zones to the upper crust. If there are rock layers with low permeability in the upper crust covering the upwelling gas, they may become a hydrogen energy reservoir in the deep crystalline rock. In China, there may be such deep hydrogen energy storage in the eastern Qinghai-Tibet Plateau, which deserves further study.

    The deployment of semi-submersible production and storage oil platform "Deepsea No.1" signifies a significant leap in China's ability to develop deep-water oil and gas fields and to construct deep-water ocean engineering equipment. However, due to prolonged offshore operations, deep-water oil and gas platforms face environmental challenges such as corrosion from seawater, marine organism attachment, wind and wave flow. As a result, the development of underwater operation and maintenance of deep-water platform structures, including cleaning, inspection, and repair, has become a key factor for ensuring long-term safe operation. Currently, shallow-water platforms mainly rely on divers for operations. With increasing water depths, the use of underwater robots for inspection, maintenance and repair (IMR) has become an inevitable trend. Nevertheless, traditional remotely operated vehicles (ROVs) are expensive and difficult to operate because of their sizes. This paper mainly summarizes novel underwater IMR robots for marine engineering applications developed in the past decade, reviews domestic and international status of underwater maintenance robots, and discuses some typical case studies. Finally, common key technical issues of new robots and the trend for intelligent technology development in underwater maintenance robots are addressed .

    This paper provides an overview of the current development status of hydrogen energy highway transportation, rail transit, shipbuilding, and aviation in China. It analyzes the comprehensive performance of hydrogen fuel cell vehicles in China and points out that the challenges faced by Chinese hydrogen energy vehicles are mainly high costs of vehicles and fuel and insufficient refueling infrastructure. However, as China steps into the middle and late stage of urbanization, heavy-load transportation and special transportation with fixed routes provide opportunities for the development of hydrogen vehicles, and family passenger vehicles will become an important direction. Hydrogen energy rail transit will also play a role in areas where electrification is difficult. Ships and aircraft powered by hydrogen compounds will become the focus of shipbuilding and aviation industries. In the future, hydrogen energy transportation should improve planning, promote technological integration and innovation, develop new hydrogen energy transportation travel modes, build a sound policy system, and adopt carbon market mechanism to achieve a new leap.

    W boson is the elementary bosonic particle mediating the weak force and its mass is originated from electroweak symmetry breaking. Precision measurements of W boson mass provide a self-consistence check of the standard model theory and could hint at new particles or other mysteries of physics yet to be discovered. The Fermilab CDF group published the most precise result on W boson mass and found that this new measurement disagreed with the standard model's expectation by 7 sigma on the statistical significance. This finding would possibly challenge the current understanding of the standard model of particle physics.

    As a crystallization of ancient Chinese science, Traditional Chinese Medicine (TCM) has gradually entered the mainstream international medical system. Chinese and Western medicine have different scientific paradigms. Western medicine is rooted in a simplistic paradigm based on material science, while TCM follows a complex paradigm based on information science. TCM is guided by the principle of "efficacy" and operates under the concepts of "harmony between man and nature" and "harmony between man and virtue". It places the human body's information system at the core and establishes close connections between the doctor and patient, human health and the natural environment, intervention measures, as well as temporal and spatial factors. Through methods such as "syndrome differentiation and treatment", TCM achieves the transformation of information and ultimately aims to maintain health, alleviate ailments, and promote longevity. With the rise of technologies such as big data, cloud computing, and artificial intelligence, TCM, characterized by "information science", will further achieve high-quality development and ultimately realize the modernization of TCM.

    As a non-carbon clean energy, geothermal energy plays an important role in promoting the development goals of carbon peak and carbon neutrality due to its advantages of stable and continuous supply. The utilization of geothermal energy is generally divided into geothermal power generation, geothermal direct utilization and geothermal energy storage. Since 2010, global geothermal direct utilization has grown exponentially, with the installed capacity of geothermal direct utilization and annual heat utilization of about 108 GWt and 283,580 GWh, respectively. China has long ranked first in the world in terms of geothermal direct utilization. The geothermal heat pump system shows an exponential growth of about 16% every year, and the geothermal heat pump system accounts for about 72% and 60% of the installed capacity and heat utilization of the global direct utilization of geothermal heat, respectively. The average annual growth rate of geothermal power generation from 2010 to 2020 is about 4% restricted by high-temperature geothermal resources. Geothermal energy storage is the frontier field of geothermal utilization. Europe and the United States have deployed the "HEATSTORE" and "Geothermal Battery" energy storage projects respectively. The geothermal energy storage project deployed by the Geothermal Team of the Chinese Academy of Sciences has also entered the stage of key technology research and demonstration projects construction. As a huge natural energy storage, geothermal storage is the most suitable basis for storing energy and realizing a stable supply of thermal energy in a multi-energy complementary system. It can save other energy sources across seasons, realize efficient and large-scale energy storage across seasons, and improve energy utilization efficiency. Therefore, it can help achieve the development goals of carbon peak and carbon neutrality.
