The rapid spread of solar power plants onto cropland is having increasingly detrimental impacts. Targeted policy and technological solutions are urgently needed to resolve the tension between renewable energy and food production. The spatial mismatch between energy demand and supply in China exacerbates the situation. Production of solar energy is shifting from the land- and…

New software can accurately detect science papers written by the AI tool ChatGPT.Credit: Frank Rumpenhorst/dpa via Alamy A machine-learning tool can easily spot when chemistry papers are written using the chatbot ChatGPT, according to a study published on 6 November in Cell Reports Physical Science1. The specialized classifier, which outperformed two existing artificial intelligence (AI)…

Abstract Efforts to make food systems more sustainable have emphasized reducing adverse environmental impacts of agriculture. In contrast, chemical and biological processes that could produce food without agriculture have received comparatively little attention or resources. Although there is a possibility that someday a wide array of attractive foods could be produced chemosynthetically, here we show…

I am off to New York for a Court hearing on November 13th, but also attending The Critics Choice Association (CCA) Gala and Awards Ceremony the evening before. I hope my tux fits. The Critics Choice Association (CCA) has announced the nominees for the Eighth Annual Critics Choice Documentary Awards (CCDA). The winners will be revealed at a Gala Event on Sunday,…

Abstract Deep neural networks (DNNs) are phenomenally successful machine learning methods broadly applied to many different disciplines. However, as complex two-party computations, DNN inference using classical cryptographic methods cannot achieve unconditional security, raising concern on security risks of DNNs’ application to sensitive data in many domains. We overcome such a weakness by introducing a quantum-aided…

Share of sentiments and emotions as well as share of conspiracy-related tweets for each technology category. Credit: Finn Müller-Hansen A survey of more than a million social media posts suggests that people feel more positive about nature’s ability to solve climate change than human technology, according to new research published in the journal Global Environmental…

Abstract Acoustic metamaterials are increasingly being considered as a viable technology for sound insulation. Fractal patterns constitute a potentially groundbreaking architecture for acoustic metamaterials. We describe in this work the behaviour of the transmission loss of Hilbert fractal metamaterials used for sound control purposes. The transmission loss of 3D printed metamaterials with Hilbert fractal patterns…

Abstract Industrial ecology (IE) is the process of constructing industrial-ecological systems (IES) with the realization of the mutual benefits for industrial system (IS) and ecological system (ES). Therefore, the IE level depends on the IES development and the relationship between IS and ES. This paper calculated the development index of ES and IS to account…

Abstract China contributed nearly one-fifth of the world maize production over the past few years. Mapping the distributions of maize cropland in China is crucial to ensure global food security. Nonetheless, 10 m maize cropland maps in China are still unavailable, restricting the promotion of sustainable agriculture. In this paper, we collect numerous samples to produce…

Abstract Knowledge tracking is to analyze the mastery of students’ knowledge through the learning track. This is very important for online education, since it can determine a learner’s current knowledge level by analyzing the learning history and then make recommendations for future learning. In the past, the commonly used model for knowledge tracking is the…
