修复地球“创伤”有新招（一周科技观察）

Group 1 - The Southeast University research team has developed a bionic self-generating and energy-storing concrete, which can store approximately one day's electricity for residential use and improve photovoltaic utilization by over 30%, reducing electricity costs by more than 50% [1] - The application of technology in environmental protection is becoming a crucial method to address ecological threats, enabling more efficient pollution monitoring and remediation, promoting energy structure transformation, and facilitating circular economy development [1] - A new engineered bacterial strain has been successfully constructed by a Chinese research team to simultaneously degrade five types of organic pollutants in high-salinity wastewater, demonstrating high degradation efficiency on complex pollutants [1] Group 2 - The issue of plastic pollution has gained significant international attention, with over 300 million tons of plastic waste generated globally each year, of which only 9% is recycled [2] - Researchers from the Chinese Academy of Sciences have developed a floating titanium dioxide material that can decompose waste plastics under light, achieving decomposition efficiency that is dozens to hundreds of times higher than traditional materials, while significantly reducing costs [2] - A team from the University of Manchester has created special light-driven enzymes that work under visible light, potentially offering more environmentally friendly and efficient solutions for drug and important chemical production [2] Group 3 - Researchers at CERN have successfully transformed lead into gold using high-energy physics methods, demonstrating the theoretical feasibility of directional element modification, which may provide new approaches for the safe disposal of nuclear waste [3] - The need for more technological means and broader applications is emphasized in the context of the global ecological crisis, aiming to repair Earth's "injuries" without creating new "scars" [3] - When innovation is driven by the goal of enhancing human well-being and achieving harmony between humans and nature, science and technology can provide more momentum for sustainable development [3]
