The Korea Railroad Research Institute (KRRI) (President: Sagong Myung) conducted a field demonstration on May 13 (Wed.) at a concrete sleeper storage site near Gimyujeong Station in Chuncheon for railway industry officials and other stakeholders, showcasing the “End-of-Life Concrete Sleeper Recycling System,” which crushes, separates, and sorts waste concrete into recyclable materials such as reinforcing steel and aggregates.

The tea industry is an important part of China’s agricultural economy, but the industrial development challenge of “who will grow tea and how to grow it well” has become increasingly prominent. In the face of realities such as accelerating aging of the rural labor force and insufficient resource endowments of smallholder farmers, promoting the implementation and widespread adoption of agricultural socialized services has become a key path to overcoming the development dilemma of the tea industry.

A research team has identified the odor-active compounds responsible for the soapy and metallic off-flavors when cold-pressed rapeseed oil undergoes alkali refining. 

A new review study in the Journal of Medical Internet Research published by JMIR Publications shows that adapting existing language models is the key to ensuring they can safely and effectively assist with clinical diagnoses, patient triaging, and treatment planning in real-world health care settings.

Biomedical researchers at Texas A&M University’s College of Engineering and the University of São Paulo have developed dissolvable microneedles, each only a few times wider than a human hair, that can deliver therapeutic drugs and redistribute light beneath the skin, offering a practically painless, scar-free alternative to invasive surgery and a new path to treating skin cancer and other light-responsive conditions.

With the accelerated advancement of lunar and Mars exploration programs, long-term human habitation on extraterrestrial bodies faces the severe challenge of extreme diurnal temperature variations. Phase change materials (PCMs), owing to their ability to store or release substantial latent heat during solid–liquid phase transitions while maintaining a nearly constant temperature, have become an ideal solution for space thermal control systems. However, in the microgravity environment of space, the ground-dominant natural convection tends to disappear, and thermocapillary convection may become the prevailing heat transfer mechanism; in low-gravity environments such as those on the Moon and Mars, the coexistence and competition between these two convective regimes remain unclear. Existing studies have predominantly focused on either Earth's gravity or pure microgravity conditions, with a notable scarcity of research on the coupled effects of thermocapillary and natural convection at intermediate gravity levels. The melting dynamics of two typical organic PCMs, succinonitrile and n-octadecane, under low-gravity conditions have not yet been systematically elucidated. Therefore, clarifying the roles of thermocapillary convection under varying gravity levels and container geometries holds significant engineering guidance for the design of efficient space thermal control systems.
