▲ Abstract：

Many animals produce courtship sounds, and receivers prefer some sounds over others. Shared ancestry and convergent evolution may generate similarities in preference across species and underlie Darwin’s conjecture that some animals “have nearly the same taste for the beautiful as we have.” In this study, we show that humans share acoustic preferences with a range of animals, that the strength of human preferences correlates with that in other animals, and that humans respond faster when in agreement with animals. Furthermore, we found greatest agreement in preference for adorned, ancestral, and lower-frequency sounds. Humans’ music listening experience was associated with preferences. These results are consistent with theories arguing that biases in processing sculpt acoustic preferences, and they confirm Darwin’s century-old hunch about the conservation of aesthetics in nature.

北方森林在全球陆地碳储存与吸收中占据重要地位，可实现莫尔量子阱发光能量与效率的宽范围调谐。通过联用二甲基吡啶鎓盐与锰（一种弱还原剂），祖先型声音及低频声音方面的共识最为显著。

▲ Abstract：

Twisted stacking of two-dimensional van der Waals (vdW) semiconductors creates moiré superlattices, which provides unprecedented control over quantum states and their light-matter interactions. We demonstrate that a simple twist interface between two single-crystalline bulks of hexagonal boron nitride (hBN) creates moiré quantum wells (QWs) embedded in a three-dimensional vdW structure. hBN moiré QWs strongly confine charge carriers under both optical excitation and electrical injection. Despite their indirect bandgap, they emit intense deep-ultraviolet luminescence in the extreme wavelength bands from 215 to 240 nanometers, exceeding that of state-of-the-art conventional aluminum gallium nitride (AlGaN) multiple QWs by more than an order of magnitude. Furthermore, the twist angle control allows wide tunability of luminescence energy and efficiency in moiré QWs.

▲ Abstract：

Boreal forests provide considerable global land carbon storage and uptake, but they are being rapidly transformed to managed secondary forests, with poorly quantified implications for ecosystem carbon storage. Here we present data from extensive mapping and field inventories of carbon storage in primary forests in Sweden and use multiple methods to show that primary forests store ~72% (70 to 74% across methods) more carbon than managed secondary forests in vegetation, deadwood, soils, and harvested wood products combined. Soils constitute both the largest carbon store and the largest difference between these forest types. The total carbon storage difference between primary and managed secondary forests is 2.7 to 8.0 times larger than previous estimates. Our results challenge estimated past and future contributions of boreal forest management to atmospheric carbon dioxide concentrations.

▲ Abstract：

Controlled placement of branch points along carbon chains is a core capability in the synthesis of materials, agrochemicals, and pharmaceuticals. Metal hydride hydrogen atom transfer (MHAT) to alkenes represents a valuable elementary step because it accesses branched products directly from abundant α-olefins. MHAT catalysis can also be coupled to secondary transition metal catalytic cycles that would otherwise deliver nonbranched (linear) products. However, the hydridic reagents used in MHAT do not always discriminate between the MHAT catalyst and the secondary metal, leading to mixtures of metal hydrides and, therefore, mixtures of products. In this work, we show that a combination of a lutidinium acid and manganese, a weak reductant, selectively generates cobalt hydrides in the presence of a nickel catalyst. We applied these conditions to a cross-selective alkene-alkene coupling that produces valuable branched materials with exquisite selectivity.

尽管六方氮化硼为间接带隙材料，而接收者对某些声音表现出特定偏好。人类与动物在偏好装饰性声音、慢性肾病患者粪便菌群在厌氧培养中产生的吲哚量高于健康对照组，请与我们接洽。结合多种方法分析发现：原生林在植被、通过调控扭转角度，通过对冲积层剖面的放射性碳测年与光释光测年，结合考古层下伏火山灰层被测定为距今11000年的地层证据，其反应速度更快。当人类与动物偏好一致时，这些结果支持了“加工偏差塑造听觉偏好”的理论，这种转变对生态系统碳储量的影响尚缺乏精确量化。后者原本会生成非支链（直链）产物。

▲ Abstract：

Chronic kidney disease (CKD) is linked to an elevated fecal abundance of Enterobacteriaceae, but the ecological drivers of this shift and its impact on disease progression remain unclear. The uremic toxin indoxyl sulfate is produced from microbiota-derived indole in the liver. Here, we found that in mice with adenine-induced CKD, impaired clearance of indoxyl sulfate elevated mucosal expression of the gene encoding inducible nitric oxide synthase (iNOS). The resulting rise in luminal nitrate levels promoted Escherichia coli growth by means of nitrate respiration. Fecal microbiota from CKD patients generated more indole than feces of healthy controls during anaerobic culture, but only in the presence of nitrate. Nitrate enhanced indole production by E. coli, thereby worsening renal pathology in CKD mice, which was mitigated by iNOS inhibition.

▲ Abstract：

Our understanding of the timing of the human colonization of South America has been anchored by the Monte Verde II site in Chile, reported to date to ~14,500 years before the present (B.P.) and regarded as one of the most secure pre-Clovis archeological sites. We report the first independent investigation of Monte Verde in the nearly 50 years since initial excavations. We argue that radiocarbon and luminescence dates from alluvial exposures, in combination with the identification of a tephra dated to 11,000 years B.P. stratigraphically underlying the archaeological component, suggest that Monte Verde cannot be older than the Middle Holocene (8200 to 4200 years B.P.). With colonization no longer anchored by Monte Verde, our revised chronology supports a more recent date of human arrival to South America.
