摘要：The lamprey occupies a pivotal position for elucidating vertebrate brain evolution. Using spatial transcriptomics and single-nucleus RNA sequencing, we generated a three-dimensional molecular atlas of the lamprey brain, identifying 209 distinct cell clusters across 14 regions. Cross-species comparisons revealed broad conservation of regional spatial architecture, defining an ancestral organizational blueprint. Within this conserved framework, however, marked lineage-specific divergence emerged...

摘要：Conflict zones are inherently hazardous and inaccessible for researchers, which results in a knowledge gap about the immediate effects of armed conflicts on the environment, particularly wildlife. We used camera-trap detections to investigate the impact of armed conflict on wildlife activity patterns before, during, and after the Russian occupation of the Chornobyl Exclusion Zone (Ukraine) in 2022 and compared it to the same period in 2021. Mammal species responded to armed conflict through im...

摘要：Membrane technologies offer an energy-efficient alternative to conventional distillation for hydrocarbon fractionation, but they suffer from a trade-off between fast liquid transport and high molecular selectivity. We report a scalable approach to fabricate polymer membranes with stable interconnected pathways by locking in their intrinsic microporosity. This locking strategy reduces polymer swelling and preserves the subnanometer pore structure in hydrocarbon liquids, resulting in 10-fold hig...

摘要：Many plants explosively launch seeds, but these natural catapults often display inefficient, unpredictable energy transfer in seed ejection. Violets (Viola spp.) address this problem by ejecting seeds successively with consistent propulsive force from a single pod, a strategy that requires sophisticated energy release. In this work, we show that Viola achieves this feat with a simple and compact structure that generates adaptive force augmentation through sequential pinching. Our biological an...

摘要：Modern amphibians are characterized by an aquatic larval stage that ends abruptly with a period of widespread tissue remodeling (metamorphosis) upon transition to terrestrial adulthood. A transient larval stage ending in gradual metamorphosis is often assumed for the earliest digited tetrapods, but direct evidence of this larval stage is lacking. Exceptionally preserved stem tetrapod hatchlings show that a transient larval stage was absent in tetrapods both before and after the fin-to-limb tra...

摘要：The main belt asteroid (52246) Donaldjohanson (DJ) is a likely member of the Erigone asteroid family. This implies that DJ is a fragment of a larger parent body that was destroyed in a collision about 155 million years ago. We report observations taken during a flyby of DJ by the Lucy spacecraft. We found that DJ is composed of two heavily cratered lobes, connected by a smoother neck, with overall dimensions 8.8 kilometers (km) by 4.4 km by 3.1 km. The crater density is consistent with the Eri...
