Step geometry–guided growth of rhombohedral graphene
菱方(ABC)堆垛石墨烯已成为探索关联与拓扑物理的平台。然而,其大规模纯相合成一直受到本征热力学亚稳态和动力学不稳定性的阻碍。在本工作中,我们提出了一种台阶几何导向的外延策略,以确定性控制层间滑移,从而实现纯相菱方石墨烯的合成。利用该方法,我们获得了面积达 160 微米×80 微米、厚度从约 15 层到约 [原文截断] 的纯相(相纯度 >99%)菱方石墨烯。
Rhombohedral (ABC)–stacked graphene has emerged as a platform for exploring correlated and topological physics. However, its large-scale, pure-phase synthesis has been hindered by intrinsic thermodynamic metastability and kinetic instability. In this work, we introduce a step geometry–guided epitaxial strategy to deterministically control interlayer slip, enabling the synthesis of pure-phase rhombohedral graphene. Using this approach, we obtained pure (phase purity > 99%) rhombohedral graphene with an area reaching 160 micrometers by 80 micrometers and thickness ranging from ~15 layers to ~

The global biogeography of passerine songs
尽管鸟鸣是理解声音交流进化的经典模型,但其全球范围内的多样性长期以来使统一框架的建立充满挑战。通过分析全球 3000 多种雀形目物种鸣声的声学结构,我们表明该声学空间可以围绕八种基本音素单元加以组织。这些音素单元的差异性使用,既受到物种生物学特征(社会组织、形态和交配系统)的驱动,也受到声音传播物理规律的影响。在热带雨林中,环境过滤 [原文截断]
Although bird songs are classic models for understanding the evolution of vocal communication, their global diversity has long made the development of a unifying framework challenging. By analyzing the acoustic architecture of songs from more than 3000 passerine species worldwide, we show that this acoustic space can be structured around eight elemental motifs. The differential use of these motifs is driven by a combination of species’ biological traits (social organization, morphology, and mating system) and the physics of sound propagation. In tropical rainforests, environmental filtering fo

University science in the US needs a coherent plan
特朗普政府持续削弱美国的科研建制,对国家更广泛的利益与福祉造成了广泛损害。上周,美国大学联合会报告称,在占全美博士学位授予量一半的主要研究型大学中,研究生入学人数较一年前下降了 15%。这不足为奇——考虑到近期移民政策对国际学生的劝退效应,以及在联邦资金前景难料的背景下各高校面临的财务不确定性。
The Trump administration continues to degrade America’s scientific establishment, causing widespread harm to the country’s broader interests and well-being. Last week, the Association of American Universities reported that graduate student enrollment in major research universities, which award half of all doctorate degrees in the United States, is down 15% compared to a year ago. And no wonder, considering the effect of recent immigration policies that deter international students and the financial uncertainties that universities are facing given the unpredictable nature of federal funding.

A global molecular code for birth order and neuronal identity in Drosophila
功能性神经环路的组装依赖于具有精确分子身份与连接性的多样化神经元的产生。要揭示整个神经系统中神经元特化与布线的一般规律,需要对其多样性进行系统且高分辨率的刻画,近年来单细胞转录组学与连接组学的进展使这一目标成为可能。然而,将神经元的分子身份与环路结构联系起来仍是一项关键挑战。本研究构建了黑腹果蝇的高分辨率发育转录组图谱
Abstract The assembly of functional neural circuits relies on the generation of diverse neural types with precise molecular identity and connectivity. Unlocking general principles of neuronal specification and wiring across the nervous system requires a systematic and high-resolution characterization of its diversity, recently enabled by advances in single-cell transcriptomics and connectomics. However, linking the molecular identity of neurons to circuit architecture remains a key challenge. Here we present a high-resolution developmental transcriptional atlas for the Drosophila melanogaster

Study explores the hedging capability of cryptocurrencies in turbulent markets
近年来可持续金融的快速发展激发了人们对绿色投资的兴趣,涉及绿色债券、环境、社会与治理(ESG)基金以及节能型加密货币等多个领域。尽管这些资产常被归入绿色金融的大范畴,但它们在市场承压时期的相互作用,至今仍未得到充分研究。
The rapid growth of sustainable finance in recent years has fueled interest in green investment, ranging from green bonds and environmental, social and governance (ESG) funds to energy-efficient cryptocurrencies. While these assets are often grouped under the broader umbrella of green finance, their interaction during periods of market stress remains largely unexplored.
Can a robot tutor give too much help? Why timing matters
学习者站在一间房间里,房中有一个瓶子、一个杯子和一本书。任务是逐步弄清每个物体应放在房间的哪个位置——桌子下面？还是椅子上？一台人形机器人给出指示,但使用的是学习者并不懂的斯瓦希里语。为了解开这个谜题,学习者必须逐步弄清机器人所说的话。
A learner stands in a room with a bottle, a cup and a book. The task is to figure out, step by step, where each object belongs in the room. Under the table? Or perhaps on the chair? A humanoid robot gives the instructions—but in Swahili, a language the learner does not know. To solve the puzzle, the learner must gradually decipher what the robot is saying.
Scientists turn modern biobanks into a new window on human evolution

Gold-catalyzed chemical reaction advances next-generation anticancer prodrugs
近年来,抗癌前药因有望在提高治疗精准度的同时减少副作用而受到医学界和科学界的高度关注。这类药物经过专门设计,通常处于无活性状态,直到被运送至体内的特定部位或处于特定生理条件时才会被激活,从而释放其治疗作用。
Anticancer prodrugs have attracted significant attention from the medical and scientific communities in recent years because of their potential to improve treatment precision while reducing side effects. These drugs are engineered to remain inactive until they are activated at specific sites or under particular physiological conditions within the body, at which point they release their therapeutic effect.
New methods for removing harmful nitrates from drinking water identified
饮用水中的硝酸盐污染是一项重大健康隐患,在农业社区尤为严重,因为化肥、畜禽粪便和化粪池系统都可能导致硝酸盐渗入地下水。许多农村家庭依赖私用水井,而这些水井往往得不到定期检测,导致部分人无意中饮用了受污染的水。
Nitrate contamination of drinking water poses a major health concern, particularly in agricultural communities where fertilizers, livestock manure and septic systems can leach nitrates into groundwater. Many rural households rely on private water wells, which may not be routinely tested, leading some to consume contaminated water without realizing it.

Now, imagine 10 other people in the cave with you, using different-colored flashlights at the same time. Suddenly, you can no longer tell which light is coming from your gemstone, which light is from another flashlight or which light is coming from a reflection off another unknown object. That is what echolocation with multiple, overlapping frequencies would be like. But now, imagine if every person in the cave were using a flashlight of the same color. The glint from the
Native fine-flavor cacao can match commercial varieties in yield, study finds
在秘鲁北部小农户农场开展的一项研究表明,本土风味可可品种 Blanco de Piura 能够达到与拉丁美洲广泛种植的商业品种相当的产量水平。该研究由国际生物多样性联盟与 CIAT 及哥廷根大学联合 Norandino 农业合作社共同开展,结果显示以卓越风味和香气著称的 Blanco de Piura 每公顷可生产 1200 至 1500 公斤干可可豆。然而,如此高的产量有赖于良好的 tr
A study carried out on smallholder farms in northern Peru shows that Blanco de Piura, a native fine-flavor cacao variety, can achieve productivity levels comparable to those of commercial varieties widely grown across Latin America. The research, led by the Alliance of Bioversity International and CIAT and the University of Göttingen in collaboration with Cooperativa Agraria Norandino, shows that Blanco de Piura—renowned for its exceptional flavor and aroma—can produce an average of 1,200 to 1,500 kilograms of dry beans per hectare. Achieving such high productivity, however, depends on good tr

Hydrogel electrode improves stability of insect-based odor sensors for drones
无人机正越来越多地用于灾害响应、基础设施检查和环境监测。然而,大多数无人机系统主要依赖摄像头和其他视觉传感器,在烟雾、灰尘、黑暗或建筑物倒塌的情况下会失效。嗅觉感知可提供有价值的互补能力,使无人机能够探测到仅凭视觉感知无法识别的气体泄漏和化学排放。然而,一个重大挑战限制了此类生物混合传感器的实际应用:离体的昆虫触角在逐渐干燥的过程中会不断丧失信号质量。
Drones are increasingly being used for disaster response, infrastructure inspection and environmental monitoring. However, most drone systems rely primarily on cameras and other visual sensors, which can become ineffective in smoke, dust, darkness or collapsed structures. Odor sensing could provide a valuable complementary capability by enabling drones to detect gas leaks and chemical emissions that cannot be identified through visual sensing alone. Yet a major challenge has limited the practical use of such biohybrid sensors: Excised insect antennae gradually lose signal quality as they dry o

Review finds lack of evidence as to whether planting around our homes reduces the pollution we breathe
由东伦敦大学(UEL)牵头的一项新综述揭示了空气污染研究中的一个重大盲区。尽管家庭花园覆盖了英国城镇和城市的广袤区域,研究人员却未找到任何直接证据表明这些花园能够降低污染水平或改善居民在家中所呼吸的空气。家庭花园在空气质量中所扮演的角色存在着巨大的认知空白。
A new review led by the University of East London (UEL) has uncovered a major blind spot in air pollution research. Despite domestic gardens covering vast areas of Britain's towns and cities, researchers found no direct evidence showing whether they reduce pollution levels or improve the air people breathe at home. There is a huge gap in understanding the role of domestic gardens in air quality.
