  摘要：At present, more than 700 million people live with caloric hunger, and more than two billion suffer from micronutrient deficiencies, known as 'hidden hunger'. From an agricultural viewpoint, three major objectives need to be worked towards simultaneously to achieve zero hunger (the United Nations Sustainable Development Goal 2): (1) enhanced yield; (2) higher vitamin and mineral density to sustain recommended daily intake (multi-biofortification); and (3) enhanced climate-change resilience. Al...

  摘要：Most lower-extremity assistive robots are designed to actively assist gait1, 2, 3, 4, 5, 6-7 without considering long-term neuromuscular adaptations8, 9, 10-11. Here we present a lightweight (0.96 kg) robot that administers isokinetic resistance training to sustain neuromuscular rehabilitation after removal. The device integrates a variable stiffness mechanism with a back-drivable damping motor to make available safe, portable and customizable resistance training to juveniles with spinal muscu...

  摘要：Friction slows down moving objects at both macroscopic and microscopic scales(1). At the electronic level, quantum friction describes direct transfer of momentum between a liquid and the electrons of a solid(2). Owing to its microscopic nature, this phenomenon remains experimentally challenging to capture(3). Here we show that near-infrared fluorescent single-walled carbon nanotubes (SWCNTs) exhibit light-induced quantum friction in water. It is measured by observing an excitation-power-depend...

  摘要：Whale falls are biodiversity oases at seabeds1, 2, 3, 4, 5-6, yet their record from the oceans has remained sparse and fragmentary6,7. Here we report the discovery of a vast whale necropolis in the Diamantina Zone (4,616- to 7,001-m depth), extending about 1,200 km along the sea floor of the southeastern Indian Ocean. This area has a deep and extensive accumulation comprising five modern natural whale-fall communities and 476 fossil cetaceans recorded. We show that carcasses host specialized c...

  摘要：The cycle of scientific discovery is frequently bottlenecked by the slow, manual creation of software to support computational experiments1. To address this, we present Empirical Research Assistance (ERA), an artificial intelligence (AI) system that creates expert-level scientific software whose goal is to maximize a quality metric. The system uses a large language model (LLM) and tree search2 to systematically improve the quality metric and intelligently navigate the large space of possible s...
