Nitrogen fertilizers are essential for crop production, but much of the nitrogen applied to agricultural soils is lost before plants can use it. These losses not only waste valuable nutrients but also contribute to environmental pollution and greenhouse gas emissions. Scientists have now discovered that adding manganese to biochar can help soil retain more nitrogen by strengthening a natural microbial process.
Agricultural residues, wood waste, and other discarded plant materials could become valuable resources for cleaner energy and environmental technologies. Yet producing consistently high-performing carbon materials from these renewable resources remains a major challenge. Scientists now highlight a critical reason: the properties of the original biomass can determine how well the final carbon material performs.
Chinese households spent an average of RMB 8,139 per child on regular full-time education, according to a nationwide study based on 2019 survey data. The findings reveal substantial differences in education spending between rural and urban families and across income groups, particularly when it comes to tutoring and other out-of-school learning. Public investment, meanwhile, has helped narrow funding gaps in compulsory education.
Do high-achieving students focus so much on academic success that they become less concerned about others and society? A study of 2,633 junior high school students in Shanghai challenges this assumption. The findings show that top-performing students scored significantly higher than their peers across all seven dimensions of moral responsibility, with particularly strong differences in responsibility for the future, collective responsibility, and social responsibility.
