The experimental science known as X-ray crystallography is by far the most effective way to ascertain how atoms are arranged in a crystalline solid in three dimensions. This technique has been employed in the field of structural chemistry and the study of biological macromolecules for more than a century. In biological crystallography, three-dimensional molecular structures including proteins and nucleic acids are ascertained atomic level. This facilitates our comprehension of the fundamental mechanisms of biomolecules, while also assisting in the exploration of new medicine development. A combination of X-ray crystallography and other techniques such as NMR spectroscopy and electron microscopy unveils the secret of life, shedding light on complex biological molecules. These techniques work together to provide a comprehensive understanding of molecular interactions and dynamics. Apart from macromolecular crystallography, the determination of crystal structures of organic, organometallic and coordination compounds, known as small molecule or chemical crystallography, is crucial and extremely valuable for comprehending the relationship between structure and properties, as well as the supramolecular interactions (such as hydrogen bonds, halogen bonds, and π–π stacking) of crystalline solids. Significantly, it also facilitates crystal engineering to enhance structural design and achieve desired functionality. This session will share current research in X-ray crystallography, feature a discussion panel on its applications, and include a comprehensive workshop focused on both small-molecule and protein X-ray crystallography.

Radioecology is a multidisciplinary scientific concerning the presence/concentration of both natural (e.g., 238U, 232Th, 226Ra, 222Rn, 40K, 7Be, 14C, and others) and artificial (e.g., 90Sr, 134Cs, 137Cs, and others) radionuclides in the environment, the complexity of their transfer processes within and between ecosystems, and the effects of ionizing radiation on human and non-human biota. Investigations in radioecology consist of field samplings and experiments, controlled-lab experiments, and laboratory procedures including radiochemistry and radioactivity measurement. Radioecological studies normally focus on three main environments in the biosphere: marine environment, freshwater environment, and land environment. They could provide necessary data for radiation dose estimation and radiological risk assessment on human and the environmental health using predictive models. Interest and studies in the area of radioecology, environmental radioactivity, and utilization of radiotracers to reveal biogeochemical and ecological processes have significantly increased to ascertain and manage radiological risks associated with both routine and accidental releases from the historical nuclear testing, the nuclear accidents/facilities, and non-nuclear facilities. This session welcomes presentations on both basic and advanced research programmes on radioecology, environmental radioactivity, and related disciplines in order to promote and advance the science of environmental radioactivity research, and to enhance the radiological protection of humans and the environment.

In a society increasingly shaped by the rapid development of science and technology—such as artificial intelligence (AI)—and global crises like climate change, food insecurity, and pandemics, the role of science communication has become more vital than ever. Effective science communication enhances public scientific literacy, helping people combat misinformation and myths that can easily spread in the digital era and have serious consequences for individuals, businesses, and society as a whole. Moreover, it fosters a culture of curiosity, critical thinking, and scientific engagement, empowering people to make informed decisions on issues that affect their lives and influence government policy. This symposium aims to bring together international participants from both academic research and professional practice to exchange insights and experiences in science communication, with a focus on advancing global efforts to promote scientific literacy.

Nature-based Solutions (NbS) enhance natural ecosystems to address climate change and biodiversity loss through restoration, protection, and sustainable management. Recognized globally, NbS are integrated into the Nationally Determined Contributions (NDCs) of over 105 countries under the Paris Agreement. In Thailand, a key NDC strategy involves generating carbon credits from the forestry and land-use sectors. However, progress toward Net Zero targets is hindered by a shortage of certified professionals and limited understanding of NbS. To overcome this, a national initiative supported by PMU-B has been launched to build technical capacity and establish demonstration sites for Green, Blue, and Teal Carbon. The project supports the development of an NbS-based research and implementation ecosystem, contributing to Thailand’s climate goals through applied science and skilled workforce development. This symposium aims to share NbS research and build networks to strengthen collaborations, leading Thailand toward effective climate mitigation and enhanced human wellbeing under the NbS framework.
