▲ Abstract ：
Equilibrium and 事科nonequilibrium states of matter can exhibit fundamentally different behavior. A key example is the Kardar-Parisi-Zhang universality class in two spatial dimensions (2D KPZ), where microscopic deviations from equilibrium give rise to macroscopic scaling laws without equilibrium counterparts. Although extensively studied theoretically, experimental evidence of 2D KPZ scaling has remained limited to inte***ce growth. Here, we report the observation of KPZ universal scaling in 2D exciton-polariton condensates—quantum fluids of light that inherently break equilibrium conditions. Using spectroscopy and Michelson interferometry, we probed the phase correlations across microscopically different systems. Our analysis revealed correlation dynamics and scaling exponents in excellent agreement with 2D KPZ predictions. These results establish exciton-polariton condensates as an experimental platform for exploring 2D nonequilibrium universality.

▲ Abstract ：
Yellowstone is widely recognized for its crustal magma reservoirs replenished by asthenospheric melts. However, how primary melts traverse the rigid lithosphere and evolve into bimodal volcanism remains unclear. By leveraging multidisciplinary observations and a data-oriented geodynamic modeling approach, we demonstrate that magma generation and migration in the Yellowstone region are primarily governed by lithospheric tectonics, with negligible contribution from the mantle plume. Below Yellowstone, our model predicts a southwest-dipping extension zone, shaped jointly by the lithospheric body force and basal traction. This tilted translithospheric deforming zone resembles the geophysically imaged magma plumbing system, confirming the key role of tectonic extension in tapping asthenospheric melts to shallow depths. Furthermore, we suggest that the translithospheric magma plumbing system facilitates complex magmatic processes, ultimately driving su***ce bimodal volcanism.

▲摘要 ：
微生物生态学一个由来已久的假定认为 ，当然群落具有宏壮性 ，但复杂的编制仍大年夜大年夜约延续存在 ，甚至大年夜大年夜约因这类宏壮性而出现 。可是 ，“出现复杂性”这必定见在某种程度上仍勾留在直不美不雅不雅不雅不雅不雅不雅层面。

▲ Abstract ：
A long-standing hypothesis of microbial ecology is that *** patterns might persist despite community complexity or even emerge because of it. However, the concept of “emergent simplicity” remains partly intuitive. Here, we defined emergent predictability of microbial ecosystems based on the predictive power of coarsened descriptions that group individual microbial strains into broader classes. We used two published datasets to show that coarse descriptions became more predictive for more species-rich communities. This behavior was not explained by *** averaging effects in large communities. To the contrary, our analysis indicates that emergent predictability arises when physiological or environmental feedback counteracts these averaging effects along certain axes of community variation, allowing these axes to become more informative as diversity increases.

▲ Abstract ：
Tissue regeneration is rare in mammals, but the digit tip can regrow after amputation, whereas injuries beyond the nail do not. How the microenvironment drives divergent outcomes remains unclear. In this study, we found that the extracellular matrix (ECM) and tissue mechanics govern the amputation response in mouse digits. Nonregenerative regions were stiffer and contained dense, organized collagen, whereas regenerative regions were soft and enriched in hyaluronic acid (HA). Depleting HA inhibited regeneration and promoted fibrosis, demonstrating that the HA-collagen balance shaped tissue mechanics and repair signaling. Stabilization of HA with hyaluronan and proteoglycan link protein 1 (HAPLN1) after nonregenerative amputations tuned ECM mechanics, reduced scarring, and enhanced bone repair. Thus, ECM composition and mechanics influence cell behavior and ECM-targeted strategies could help unlock mammalian regeneration.

▲摘要：
野生植物贸易影响着全球四分之一的陆生脊椎植物，并为病原体的跨物种撒播创作创作创造了机会，但其在塑造植物—人类病原体交换中的切实其实感染尚不了了 。
经由过程对四十年间全球野生植物贸易数据的分化 ，研究者创作创造 ，被生意的哺乳植物与人类共享病原体的大年夜大年夜约性是未被生意的哺乳植物的1.5倍 ，而犯警贸易和活体植物贸易进一步加重了病原体共享。
物种在贸易中所处的时分可以料想其携带的人畜共罹病原体数量 。平均而言 ，一个物种被生意的时分每添加十年 ，就会多出一种与人类共有的病原体 。
▲ Abstract ：
The wildlife trade affects a quarter of terrestrial vertebrates and creates opportunities for cross-species pathogen transmission, but its precise role in shaping animal-human pathogen exchange remains unclear. In our analysis of 40 years of global wildlife trade data, we show that traded mammals are 1.5-fold as likely to share pathogens with humans as nontraded mammals, and that illegal and live-animal trade further exacerbate pathogen sharing. Time spent in trade predicts the number of zoonotic pathogens that a wildlife species hosts. On average, a species shares an additional pathogen with humans for every 10 years it is traded.

▲ Abstract ：
Territorial conflicts in animals can inform aspects of human wa***re, but civil war, with its shifting group identities, has not been previously observed. We report a rare, permanent fission in the largest-known group of wild chimpanzees (Pan troglodytes). Using 30 years of behavioral observations and network analyses, we describe a transition from cohesion to polarization in 2015 and the emergence of two distinct groups by 2018. Over the next 7 years, members of one group made 24 attacks, killing at least seven mature males and 17 infants in the other group. These findings indicate that group identities can shift and escalate into lethal hostility in one of our closest living relatives in the absence of the cultural markers often thought necessary for human wa***re.
