The China National Space Administration plans to launch the asteroid sample-return mission TianWen-2 with the target being the near-Earth asteroid 2016 HO3. The TianWen-2 spacecraft mainly focuses on surface sampling on the near-Earth asteroid 2016 HO3. the whole TianWen-2 spacecraft will be controlled to achieve touchdown and sampling rather than releasing a small lander or ejecting a projectile. Small celestial bodies usually have an extremely low surface gravity and are covered with granular material a centimeter in size or smaller in the form of regolith. The dispersion, friction, and nonlinear dissipation of inelastic collision between particles make a regolith surface behave like a solid or a fluid at the macroscopic level, exhibiting phenomena such as deformation, flow, and ejection. Thus, sampling on a low-gravity regolith-covered surface with unknown physical properties is particularly challenging and risky. In order to successfully implement an in situ exploration, it is of great significance to analyze the influence of regolith soil on the sampling process of the spacecraft on the surface of the asteroid and comprehensively understand and evaluate spacecraft dynamics and control behavior during sampling.

Sustainable city management recognises the importance of not only the busy above-ground urban systems but also the invisible underground infrastructure, utilities, and hidden heritage and their stories. The Hong Kong Polytechnic University (PolyU) is at the fore-front of geospatial and near-surface geophysical technologies, advancing land surveying research that supports cultural preservation and the sustainable development urban environment.

Bud dormancy allows perennial plants to survive winter, but insufficient winter chill under warming climates disrupts this natural cycle and reduces flowering quality. 

γ-ray astronomy has matured significantly over the course of the last decade and a half, leading to the exploration of the high-energy universe with unprecedented sensitivity. The observation of the low-energy γ-ray (0.1 to 30 MeV) sky has been significantly limited since the Imaging Compton Telescope (COMPTEL) instrument aboard the Compton Gamma Ray Observatory (CGRO) satellite was decommissioned in 2000. The exploration of γ-ray photons within this energy band, often referred to as the MeV gap, is crucial to address numerous unresolved mysteries in high-energy and multi-messenger astrophysics. Although several large MeV γ-ray missions have been proposed (e.g., e-ASTROGAM, AMEGO, and COSI), most of these are in the planning phase, with launches not expected until the next decade, at the earliest. Recently, there has been a surge in proposed CubeSat missions as cost-effective and rapidly implementable pathfinder alternatives. An MeV CubeSat dedicated to γ-ray astronomy could serve as a valuable demonstrator for large-scale future MeV payloads.

Researchers led by Prof. XU Zhiheng from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences, revealed the important roles of POSH phase separation and its co-condensates with SHANK2/3 in the synaptic targeting of SHANK2/3 and synaptogenesis.

Leaf vasculature plays a pivotal role in nutrient transport and leaf morphology.

The research team led by Dr. Jang SeGyu at the Functional Composite Materials Research Center of the Korea Institute of Science and Technology (KIST, President Oh Sang-rok) and the research team led by Professor Choi Siyoung at the Department of Bio and Chemical Engineering of the Korea Advanced Institute of Science and Technology (KAIST, President Lee Kwang-hyung) announced the development of a high-density BNNT protective shield. This shield, created by densely-packed BNNTs, is robust, efficiently conducts heat, and effectively blocks cosmic radiation.

A new study reveals that interview-based sighting histories can reliably estimate the relative abundance of Indo-Pacific humpback dolphins in Chinese coastal waters. By transforming local ecological knowledge into quantitative indices, researchers found strong correlations with actual population data. This method offers an affordable and practical alternative for monitoring marine megafauna in regions where traditional surveys are limited by cost and logistics.
