研究:一些无花果树可吸收并“石封”大气中二氧化碳

Core Insights - An international study has discovered that certain fig trees can absorb carbon dioxide from the atmosphere and store it as calcium carbonate "stones" in the surrounding soil, providing a natural solution to climate change while improving soil quality and generating economic benefits [1][2] Group 1: Carbon Sequestration Mechanism - Trees convert carbon dioxide into organic carbon through photosynthesis, which forms their trunks, branches, roots, and leaves, making afforestation a potential method for reducing carbon emissions [1] - Some trees utilize carbon dioxide to generate calcium oxalate crystals, which, when partially decayed, transform into calcium carbonate with the help of specific bacteria or fungi, enhancing soil pH and nutrient availability [1] - Inorganic carbon in calcium carbonate has a longer lifespan in soil compared to organic carbon, making it a more effective method for carbon sequestration [1] Group 2: Research Findings - A research team from institutions including the University of Zurich analyzed three species of fig trees in Samburu County, Kenya, identifying areas where calcium carbonate forms and the microbial communities involved in this process [1] - The study found that calcium carbonate forms not only on the surface of the tree trunks but also within the wood structure, likely due to microbial decomposition of surface crystals [1] - Among the three fig tree species studied, one showed the highest efficiency in converting carbon dioxide to calcium carbonate for carbon sequestration, prompting further analysis of its water requirements and fruit yield to assess its agricultural and forestry applicability [2]
新型“活体建筑材料”可从空气中吸收二氧化碳

Core Insights - Researchers have developed a 3D printable "living gel" made from photosynthetic cyanobacteria that efficiently removes carbon dioxide from the air [1][2] - This living material requires only sunlight, carbon dioxide, and nutrient-rich artificial seawater for growth, and it can absorb significantly more carbon dioxide than it stores through organic growth [1][2] Group 1 - The new material can absorb approximately 26 milligrams of carbon dioxide per gram over a period of 400 days, with most of it being stored in mineral form [2] - The incorporation of mineral deposits enhances the mechanical strength of the material, allowing it to harden over time [2] - The hydrogel, which serves as the carrier material, is designed to efficiently transmit light, carbon dioxide, water, and nutrients, facilitating uniform distribution of microorganisms [2] Group 2 - This low-energy, environmentally friendly material can sequester carbon dioxide from the atmosphere and may complement existing chemical carbon sequestration processes [2] - Future research will explore the potential of using this material as a coating for building exteriors, enabling continuous carbon sequestration throughout the building's lifecycle [2]
大国院士丨正因为难,所以必须要干——专访中国科学院院士焦念志

Core Insights - The article discusses the urgent challenge of global warming and highlights the ocean's role as a significant carbon sink, capable of absorbing vast amounts of carbon dioxide [2][3] - A Chinese scientist, Jiao Nianzhi, has proposed an innovative mechanism called the "microbial carbon pump" to enhance the ocean's ability to sequester carbon [2][5] - The "International Marine Negative Emission Science Plan" led by Jiao aims to provide a global solution for carbon management based on Chinese practices [8] Group 1: Ocean's Carbon Absorption Capacity - The ocean absorbs approximately 2 billion tons of carbon dioxide annually, which is equivalent to the emissions from about 800 million gasoline cars [3] - The ocean's carbon storage capacity is about 50 times that of the atmosphere and 20 times that of land [3] Group 2: Microbial Carbon Pump Theory - Jiao Nianzhi's "microbial carbon pump" theory suggests that microscopic marine organisms can be utilized to enhance carbon absorption [5][6] - The process involves organic carbon particles being encapsulated, preventing them from being consumed by bacteria, thus allowing them to settle on the ocean floor for long-term storage [6] Group 3: International Collaboration and Research - The "International Marine Negative Emission Science Plan" has garnered support from 79 institutions across 33 countries, focusing on collaborative research to explore marine carbon sequestration mechanisms [8] - Jiao emphasizes the importance of sharing knowledge and promoting scientific collaboration on a global scale [8]
