  摘要：Bioelectronic interfaces demonstrate promising applications in health monitoring, medical treatment, and augmented reality. However, conformally wrapping these film devices onto three-dimensional surfaces often leads to stress-induced damage. We propose a drop-printing strategy that enables damage-free film transfer using a droplet. The droplet acts as a lubricating layer between the film and the target surface, facilitating local sliding during shape-adaptive deformation. This mechanism preve...

  摘要：Habitat fragmentation, in which contiguous forests are broken into smaller, isolated patches, threatens biodiversity by disrupting species movement, shrinking populations, and altering ecosystem dynamics. Past assessments suggested declining global fragmentation, but they relied on structure-based metrics that overlook ecological connectivity. We analyzed global forest fragmentation from 2000 to 2020 using complementary metrics that captured patch connectivity, aggregation, and structure. Conn...

  摘要：Malaria parasite fertilization occurs in the midgut of a female Anopheles mosquito. Blocking fertilization within the mosquito can prevent malaria transmission. Plasmodium falciparum Pfs230 and Pfs48/45 proteins are critical for male fertility and transmission of the malaria parasite. They form a core fertilization complex, but it is unknown how they interact. We determined a cryo-electron microscopy structure of the endogenous Pfs230-Pfs48/45 complex showing that Pfs48/45 interacts with Pfs23...
• Fire heat affects the impacts of wildfires on air pollution in the United States AI翻译

  摘要：Conventional wisdom suggests that wildfires in the western United States (WUS) degrade air quality nationwide as a result of aerosol emissions and eastward transport. However, we found that heat produced by wildfires, a commonly neglected effect, can reduce fine particle concentrations (PM2.5) in the eastern United States (EUS) by an amount comparable to the increases in the WUS during the fire season. This phenomenon arises from fire heat-induced convection in the WUS and subsequent downstrea...
• Machine learning-based penetrance of genetic variants AI翻译

  摘要：Accurate variant penetrance estimation is crucial for precision medicine. We constructed machine learning (ML) models for 10 diseases using 1,347,298 participants with electronic health records, then applied them to an independent cohort with linked exome data. Resulting probabilities were used to evaluate ML penetrance of 1648 rare variants in 31 autosomal dominant disease-predisposition genes. ML penetrance was variable across variant classes, but highest for pathogenic and loss-of-function ...
• Vegetation changes the trajectory of river bends AI翻译

  摘要：A primary axiom in geoscience is that the evolution of plants drove global changes in river dynamics. Notably, the apparent sinuosity of rivers, derived from the variance of sediment accretion direction measured in rocks, substantially increased when land plants evolved, around 425 million years ago. This led to the hypothesis that the rise of vegetation triggered river meandering. Recent studies of barren, meandering rivers challenge this notion, but the Paleozoic shift in the geometry of riv...
• Classical-decisive quantum internet by integrated photonics AI翻译

  摘要：Classical and quantum technologies have traditionally been viewed as orthogonal, with classical systems being deterministic and quantum systems inherently probabilistic. This distinction hinders the development of a scalable quantum internet even as the global internet continues expanding. We report a classical-decisive quantum internet architecture in which the integration of quantum information into advanced photonic technologies enables efficient entanglement distribution over a commerciall...

  摘要：Horsepower revolutionized human history through enhanced mobility, transport, and warfare. However, the suite of biological traits that reshaped horses during domestication remains unclear. We scanned an extensive horse genome time series for selection signatures at 266 markers associated with key traits. We detected a signature of positive selection at ZFPM1-known to be a modulator of behavior in mice-occurring similar to 5000 years ago (ya), suggesting that taming was one of the earliest ste...
• Seismic evidence for a highly heterogeneous martian mantle AI翻译

  摘要：A planet's interior is a time capsule, preserving clues to its early history. We report the discovery of kilometer-scale heterogeneities throughout Mars' mantle, detected seismically through pronounced wavefront distortion of energy arriving from deeply probing marsquakes. These heterogeneities, likely remnants of the planet's formation, imply a mantle that has undergone limited mixing driven by sluggish convection. Their size and survival constrain Mars' poorly known mantle rheology, indicati...

  摘要：Eukaryotic cells have evolved sophisticated quality control mechanisms to eliminate aggregation-prone proteins that compromise cellular health. Central to this defense is the ubiquitin-proteasome system, where UBR4 acts as an essential E4 ubiquitin ligase, amplifying degradation marks on defective proteins. Cryo-electron microscopy analysis of UBR4 in complex with its cofactors KCMF1 and CALM1 reveals a massive 1.3-megadalton ring structure, featuring a central substrate-binding arena and flex...
