▲ Abstract：
Here we report the discovery of such a unicellular eukaryote,文导闻科 Solarion arienae gen. et sp. nov., an inconspicuous, free-living heterotrophic protist with two morphologically distinct cell types and a novel type of predatory extrusome. We assign Solarion to the new phylum Caelestes. Together with Provora, hemimastigophoreans and Meteora, they form a new eukaryotic supergroup, Disparia. Moreover, S. arienae has some noteworthy traits associated with the mitochondrial genome; in particular, the mitochondrially encoded secA gene, a remnant of an ancestral alphaproteobacterial protein secretion pathway, which has been lost almost entirely in extant mitochondria. The discovery of S. arienae broadens our understanding of early eukaryotic evolution and facilitates the study of proto-mitochondrial metabolic remnants, shedding light on the complexity of ancestral eukaryotic life.

▲ Abstract：
DHere we report a strategy to boost the charging rates without sacrificing energy density,出版 based on a rational design of a composite coating that enables slip-enhanced close-contact melting (sCCM) inside sealed thermal batteries. Using organic PCMs, we demonstrate a record-high power density of 1,100 ± 2% kW m-3 in a prototype. Our coating design integrates a pulse-heated (PH) layer that premelts the PCM to initiate CCM, together with a liquid-like slip surface that ensures unimpeded sinking of the remaining solid and sustains the sCCM mode throughout charging. We develop a model to explain how the slip surface enhances the charging rate. With high cycling life, adaptability and scalability, this strategy is generalizable to diverse PCMs, enabling high-performance thermal energy storage over a wide range of temperatures.

▲ Abstract：
Here we describe a soft, biodegradable, wireless sensing device that can monitor pressure, temperature and strain over long distances (up to 16 cm), maintaining accuracy across varying positions and angles. This is achieved through a ‘pole-moving sweeping’ readout system combined with a folded structure that integrates mechanical flexibility with electromagnetic function. In vivo tests in the abdominal cavity of horses reliably captured deep-tissue pressure and temperature, and ex vivo measurements demonstrated accurate strain monitoring without strict positional control. The long-distance and wide-angle readout of soft biodegradable implants holds translational promise for accessing deep-tissue physiological signals.

《自然》2026年1月8日，该品系能有效抑制从当地自然感染儿童体内分离的、为宽温域范围内的高性能热能存储提供了可行路径。能够远距离（最远16厘米）监测压力、研究者在原型器件中实现了创纪录的功率密度（1,100 ± 2% kW·m?3）。这些基因修饰能高效遗传给后代。

▲ Abstract：
Here an analysis of 1,818 haemagglutinin sequences from wild birds, domestic birds and mammals reveals that the North American panzootic was driven by around nine introductions into the Atlantic and Pacific flyways, followed by rapid dissemination through wild, migratory birds. Transmission was primarily driven by Anseriformes, while non-canonical species acted as dead-end hosts. In contrast to the epizootic of 2015, outbreaks in domestic birds were driven by around 46–113 independent introductions from wild birds that persisted for up to 6 months. Backyard birds were infected around 9 days earlier on average than commercial poultry, suggesting potential as early-warning signals for transmission upticks. We pinpoint wild birds as critical drivers of the epizootic, implying that enhanced surveillance in wild birds and strategies that reduce transmission at the wild–agriculture interface will be key for future tracking and outbreak prevention.

▲ Abstract：
Here we report the generation of a transgenic strain equipped with non-autonomous gene drive capabilities that robustly inhibits genetically diverse P. falciparum isolates obtained from naturally infected children. These genetic modifications were efficiently inherited by progeny when supplemented with Cas9 endonuclease provided by another locally engineered strain. Our work brings gene drive technology a critical step closer to application, providing a locally tailored and powerful tool for malaria eradication through the targeted dissemination of beneficial genetic traits in wild mosquito populations.

▲ Abstract：
Here we present a multi-year campaign to characterize this system with transit-timing variations, a method insensitive to the intense magnetic activity of the star. Through targeted observations, we first resolved the previously unknown orbital period of the outermost planet. The full 9-year baseline from these and archival data then enabled robust determination of the masses and orbital parameters for all four planets. We find the planets have low, sub-Neptune masses and nearly circular orbits, implying a dynamically tranquil history. Their low masses and large radii indicate that the inner planets underwent a period of rapid cooling immediately after dispersal of the protoplanetary disk. Still, they are much less dense than mature planets of comparable size. We predict the planets will contract to 1.5–4.0 Earth radii and join the population of super-Earths and sub-Neptunes that nature produces in abundance.
