Multi-Messenger Astronomy, Cosmic Rays, and Space Weather Impacts are interconnected fields of study in astrophysics and space science that aim to understand the universe through multiple channels of observation and analysis.
Multi-Messenger Astronomy involves studying celestial phenomena using various signals, including electromagnetic radiation, cosmic rays, neutrinos, and gravitational waves. By analyzing data from these messengers, scientists can gain a comprehensive understanding of cosmic events like supernovae, black hole mergers, and neutron star collisions.
Cosmic Rays are high-energy particles, primarily protons and atomic nuclei, that travel through space at nearly the speed of light. They originate from sources such as supernova remnants and active galactic nuclei, providing insights into particle acceleration processes and magnetic fields in the universe. Studying cosmic rays helps understand the composition and dynamics of galaxies and beyond.
Space Weather refers to dynamic conditions in space influenced by the Sun's activity, generating events like solar flares and coronal mass ejections. These events can disrupt Earth's magnetosphere and ionosphere, impacting satellite communications, GPS navigation, power grids, and endangering astronauts and spacecraft. Understanding and predicting space weather are crucial for safeguarding technological infrastructure and space missions. Bringing together these three areas—multi-messenger astronomy, cosmic rays, and space weather impacts—provides a holistic perspective on the interconnectedness of astrophysical processes and their effects on our solar system and beyond. Research in this field involves observations from ground-based and space-based telescopes, particle detectors, and space weather monitoring instruments, as well as theoretical modelling and data analysis techniques. Collaboration among astronomers, astrophysicists, space physicists, and engineers is essential for advancing our understanding of the universe and mitigating the impacts of space weather on society. It would bring together researchers and experts from various disciplines to discuss recent advancements, challenges, and opportunities in understanding cosmic phenomena and their effects on space weather.

Over the past 30 years, scientific research has transformed the perception of tropical forest ecosystem restoration from the wishful thinking of a few ecologists into a practicable reality. During the 1980–1990s, a lack of technical knowledge about the ecology and propagation of the myriad of tree species that comprise tropical forests posed a major technical obstacle to restoration. However, research, by several groups around the world over the past 3 decades, has advanced practical techniques of performing various restoration tasks: site assessment, tree-species selection, seed collection, genetic conservation, direct seeding and tree propagation, planting, maintenance and monitoring of both carbon storage and biodiversity recovery. Such research has resulted in a spectrum of effective restoration strategies, tailored to address various degradation scenarios, from simple protective measures and assisted natural regeneration (ANR), on moderately degraded sites, to the framework-species method and maximum diversity techniques, where natural regeneration is lacking, and nurse-tree plantations, on the most severely degraded sites. The design, size and placement of restoration plots have also received considerable attention, with concepts such as wildlife corridors, buffer zones and “applied nucleation” becoming mainstream. The morning session will review progress in restoration science over the past 30 years and identify remaining knowledge gaps. Stephen Elliott will review advances in the achieved by CMU’s Forest Restoration Research Unit, whilst guest speaker, Nigel Tucker, restoration ecologist, from James Cook University, will present his personal view of 40 years of restoration research from tropical north Queensland.
In the afternoon, we will explore how recent advances in technologies might be used to improve the scientific basis of global initiatives that employ forest restoration as a nature-based contribution to climate-change mitigation. Guest speaker Kate Hardwick from the Royal Botanic Gardens, Kew will review the need for more seed banks to upscale restoration, whilst Maxime Réjou-Méchain, from the French National Research Institute for Sustainable Development, will discuss how high-resolution remote sensing can contribute to restoration monitoring. The symposium will conclude with audience participation, to prioritize future research needs and thus assist prospective graduate students with research-topic selection. A poster session may also be included. A post-symposium social event, to celebrate the 30th anniversary of Chiang Mai University’s Forest Restoration Research Unit, is planned.

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. 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.

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.
