Variable-load unmanned aerial vehicles (UAVs) are key tools in smart agriculture, particularly playing a vital role in the prevention and control of crop pests and diseases. Equipped with pesticide spraying equipment, these quadrotor UAVs offer advantages such as high operating speed, low risk of chemical drift, and improved crop coverage, making them widely used in agricultural plant protection.
Researchers at Tampere University have demonstrated that light can be used to precisely reshape soft materials without mechanical contact. They have developed light‑responsive hydrogel thin films that enable programmable surfaces with high sensitivity, rapid response, precise spatial control and reversibility. The technology opens new possibilities for tunable devices in photonics, sensing and biomedicine.
Asteroids and comets are scientifically valuable targets for understanding the early Solar System and promising objects for future in situ resource utilization. However, operating robots on these small bodies remains extremely challenging because of microgravity, irregular terrain, uncertain surface properties, and very low escape velocities. A review article published in SmartBot by researchers from China University of Mining and Technology, Soochow University, and the University of Oxford provides a comprehensive overview of three core technologies for small-body sampling robots: sampling, mobility, and anchoring. The review further highlights that the success of future missions depends not only on improving each individual module, but also on understanding and optimizing their dynamic coupling as an integrated robotic system.
Enzymes are essential in industries such as food production and pharmaceuticals, but natural enzymes often need improvements for commercial applications. Researchers in Japan have developed an in vitro selection platform, SMART, which could produce custom enzyme much more quickly and cost-effectively than conventional methods.
A new UNU-INWEH report warns that the global rush for critical minerals needed for EVs, renewable energy, and AI is driving severe but often hidden water, health, and environmental harms in vulnerable communities, especially in Africa and South America. The report calls for binding global standards, stronger accountability, and fairer benefit-sharing to prevent the clean energy transition from repeating the injustices of the fossil fuel era.
A research team led by Dr. Nam Ki-Hun at the Battery Materials and Process Research Center of the Korea Electrotechnology Research Institute (KERI) has successfully developed a nano-tin (Sn) interlayer control technology to address interfacial instability between the lithium metal anode and solid electrolyte, a critical hurdle to the commercialization of all-solid-state batteries, often hailed as the next generation of batteries. The research was featured as a front cover article in Advanced Energy Materials (IF=26.0), a globally renowned journal in the field of energy and materials science ranked within the top 2.7% worldwide and has attracted widespread international recognition.
