This study investigates the under-explored impact of banking deregulation on bank risk-taking. Analyzing China's 2009 deregulation as a natural experiment, we find that deregulated banks significantly increase their risk-taking. Mechanism analysis identifies the bank balance sheet capacity channel: deregulation boosts bank net interest margins, strengthening their financial capacity and thus their risk appetite. While this policy successfully improves long-term credit access for firms in underserved regions, especially smaller ones, it creates a critical trade-off for policymakers between supporting the real economy and safeguarding financial stability.

A new study published in Biochar reports that sulfur-modified wheat straw biochar can dramatically reduce the toxic effects of vanadium contamination in rice, offering a promising and sustainable strategy to protect global food production in polluted regions. Vanadium is a heavy metal increasingly found in agricultural soils due to mining, smelting, fertilizer overuse, and wastewater irrigation. Even moderate exposure can stunt plant growth, damage photosynthesis, and impair the antioxidant defenses that keep crops healthy.

KUALA LUMPUR / GLASGOW — As the world races to meet ambitious climate targets, nature-based strategies are gaining unprecedented traction—and biomass is stepping into the spotlight not just as renewable fuel, but as a powerful carbon sink. On December 17, 2025, leading sustainability expert Prof. Dato’ Dr. Agamutu Pariatamby FASc, Senior Professor at the Jeffrey Sachs Center on Sustainable Development, Sunway University (Malaysia), will unveil groundbreaking insights into how bio-based carbon capture can deliver up to 6.7 gigatonnes of CO₂-equivalent (GtCO₂e) in annual mitigation potential by 2050—according to IPCC (2022) estimates.

Tiny charming immune cells called microglia protect the central nervous system in a multitude of ways: They provide innate immunity, shape neurodevelopment, maintain homeostasis and modulate neurological disorders. That functionality can be lost, however, when microglia acquire mutations. An concept to correct this by replacing the mutated microglia with genetically typical cells — now called microglia intervention strategy for therapy and enhancement by replacement, or MISTER — emerged five years ago and was successfully achieved in mice. This year, researchers successfully used this microglia replacement approach to halt a fatal neurological disease ALSP (adult-onset leukoencephalopathy with axonal spheroids and pigmented glia) in human patients. 

A study has revealed that the expression of the poplar sex-determining gene FERR can significantly enhance drought tolerance in plants. 

Postharvest losses in fruits, particularly apples, are a significant global issue. 

A growing body of scientific evidence reveals that primary producers—including plants and phytoplankton—possess a previously overlooked ability to internally break down and detoxify methylmercury, one of the most potent neurotoxins circulating through global food webs.

Mathematical reasoning is a fundamental aspect of intelligence, encompassing a spectrum from basic arithmetic to intricate problem-solving. Recent investigations into the mathematical abilities of large language models (LLMs) have yielded inconsistent and incomplete assessments. In response, we introduce MathEval, a comprehensive benchmark designed to methodically evaluate the mathematical problem-solving proficiency of LLMs in various contexts, adaptation strategies, and evaluation metrics. MathEval consolidates 22 distinct datasets, encompassing a broad spectrum of mathematical disciplines, languages (including English and Chinese), and problem categories (ranging from arithmetic and competitive mathematics to higher mathematics), with varying degrees of difficulty from elementary to advanced. To address the complexity of mathematical reasoning outputs and adapt to diverse models and prompts, we employ GPT-4 as an automated pipeline for answer extraction and comparison. Additionally, we trained a publicly available DeepSeek-LLM-7B-Base model using GPT-4 results, enabling precise answer validation without requiring GPT-4 access. To mitigate potential test data contamination and truly gauge progress, MathEval incorporates an annually refreshed set of problems from the latest Chinese National College Entrance Examination (Gaokao-2023, Gaokao-2024), thereby benchmarking genuine advancements in mathematical problem solving skills.

Terahertz (THz) communication has emerged as one of the key technologies for sixth-generation (6G) wireless networks. Nevertheless, the transition to higher operational frequencies poses various challenges including high-speed digital-to-analog conversion (DACs) and analog-to-digital conversion (ADCs), heterogeneous integration of optoelectronic devices, resulting in an urgent need for solutions. In this paper, we demonstrate a groundbreaking THz analog differential operator driven by diffractive neural networks (DNN), implementing ultra-fast and high-throughput analog domain differential operations. The designed multilayer all-optical DNN composed of compact dielectric metasurfaces is trained with trigonometric functions to perform analog differential computing of complex input signals by approximating the differentiation of finite decompositions of time-domain function based on the Fourier transform theory, significantly improving integration, throughput, and processing speed. Our design has been experimentally validated to successfully implement single-direction differential operation on one- and two-dimensional signals with superior structural similarity index measure (SSIM) and peak signal-to-noise ratio (PSNR), providing a promising path for the development of integrated and ultrafast THz communication systems.
