Superstable lipid vacuoles endow cartilage with its shape and biomechanics | Science Conventionally, the size, shape, and biomechanics of cartilages are determined by their voluminous extracellular matrix. By contrast, we found that multiple murine cartilages consist of lipid-filled cells called lipochondrocytes. Despite resembling ... Sexually dimorphic dopaminergic circuits determine sex preference | Science Sociosexual preference is critical for reproduction and survival. However, neural mechanisms encoding social decisions on sex preference remain unclear. In this study, we show that both male and female mice exhibit female preference but shift to male ... Decoding the molecular interplay of CD20 and therapeutic antibodies with fast volumetric nanoscopy | Science Elucidating the interaction between membrane proteins and antibodies requires whole-cell imaging at high spatiotemporal resolution. Lattice light-sheet (LLS) microscopy offers fast volumetric imaging but suffers from limited spatial resolution. DNA-based ... Local genetic adaptation to habitat in wild chimpanzees | Science How populations adapt to their environment is a fundamental question in biology. Yet, we know surprisingly little about this process, especially for endangered species, such as nonhuman great apes. Chimpanzees, our closest living relatives, are ...

In the context of the climate crisis, scientists worldwide are exploring ... Building materials could store more than 16 billion tonnes of CO2 annually | Science Achieving net-zero greenhouse gas emissions likely entails not only lowering emissions but also deploying carbon dioxide (CO2) removal technologies. We explored the annual potential to store CO2 in building materials. We found that fully replacing ... Tropical forest clearance impacts biodiversity and function, whereas logging changes structure | Science The impacts of degradation and deforestation on tropical forests are poorly understood, particularly at landscape scales. We present an extensive ecosystem analysis of the impacts of logging and conversion of tropical forest to oil palm from a large-... Dietary breadth in kangaroos facilitated resilience to Quaternary climatic variations | Science Identifying what drove the late Pleistocene megafaunal extinctions on the continents remains one of the most contested topics in historical science. This is especially so in Australia, which lost 90% of its large species by 40,000 years ago, more than ... Photonic axion insulator | Science Axions, hypothetical elementary particles that remain undetectable in nature, can arise as quasiparticles in three-dimensional crystals known as axion insulators. Previous implementations of axion insulators have largely been limited to two-dimensional ... Parallel gene expansions drive rapid dietary adaptation in herbivorous woodrats | Science How mammalian herbivores evolve to feed on chemically defended plants remains poorly understood. In this study, we investigated the adaptation of two species of woodrats (Neotoma lepida and N. bryanti) to creosote bush (Larrea tridentata), a toxic shrub ...
