Direct Numerical Simulations of Oxygen-Flame-Driven Deflagration-to-Detonation Transition in Type Ia Supernovae

Posted by klaurent October 30, 2025Peking

Kavli Affiliate: Lile Wang | First 5 Authors: Xiaoyu Zhang, Xiaoyu Zhang, , , | Summary: We present direct numerical simulations demonstrating deflagration-to-detonation transition (DDT) driven by oxygen flames in Type Ia supernova progenitors. Using the Castro hydrodynamics code coupled with the “aprox13” 13-isotope nuclear network, we simulate combustion in isolated fuel regions where oxygen […]

Trichome entanglement enhances damage tolerance in microstructured biocomposites

Posted by klaurent October 28, 2025Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Israel Kellersztein, Israel Kellersztein, , , | Summary: Achieving damage tolerance in composite materials remains a central challenge in materials science. Conventional strategies often rely on filler incorporation or chemical modification, which can limit energy dissipation and constrain structural stability. Here, we leverage the unique morphology of […]

Towards constraining cosmological parameters with SPT-3G observations of 25% of the sky

Posted by klaurent October 28, 2025Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: A. Vitrier, A. Vitrier, , , | Summary: The South Pole Telescope (SPT), using its third-generation camera, SPT-3G, is conducting observations of the cosmic microwave background (CMB) in temperature and polarization across approximately 10 000 deg$^2$ of the sky at 95, 150, and 220 GHz. This comprehensive […]

Lipid composition and mechanical force underlie multi-modal regulation of Piezo1 gating

Posted by dbos October 25, 2025October 29, 2025Rockefeller, This Week: Neuroscience

Kavli Affiliate: Roderick MacKinnon | Authors: George Vaisey and Roderick MacKinnon | Summary: Piezo1 ion channels are widely expressed cellular mechanosensors. They adopt an intrinsically curved shape when closed and are thought to open when mechanical forces applied to the membrane favor a more flattened conformation. By reconstituting Piezo1 channels into lipid vesicles, a flattened […]

Continuous partitioning of neuronal variability

Posted by dbos October 24, 2025October 29, 2025Hopkins, This Week: Neuroscience

Kavli Affiliate: Adam S. Charles | Authors: Anuththara Rupasinghe, Adam S Charles and Jonathan W Pillow | Summary: Neural variability poses a major challenge to understanding the information content of neural codes. Recent work by Goris et al. (Nat. Neurosci 2014) has provided new insights into variability in the visual pathway by partitioning it into […]

Intertwined Orders, Quantum Criticality and Skyrmions in Tunable Topological Bands

Posted by klaurent October 24, 2025Cornell

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Xuepeng Wang, Xuepeng Wang, , , | Summary: Skyrmions are emergent many-body excitations that lie at the heart of both multi-component quantum Hall-like systems and deconfined quantum criticality. In a companion article (X. Wang et al., arXiv:2507.22971), we studied a microscopic time-reversal symmetric model of tunable interacting […]

Examining the Spin Structure of Altermagnetic Candidate MnTe Grown with Near Ideal Stoichiometry

Posted by klaurent October 24, 2025October 27, 2025Peking, This Week: Astrophysics

Kavli Affiliate: Ke Wang | First 5 Authors: Qihua Zhang, Qihua Zhang, , , | Summary: Altermagnets are a recently-discovered class of materials with magnetic ordering that have a zero net magnetization and a momentum-dependent spin splitting in their band structure, arising from a collinear spin arrangement with alternating polarizations in the crystal lattice. The […]

PhysWorld: From Real Videos to World Models of Deformable Objects via Physics-Aware Demonstration Synthesis

Posted by klaurent October 24, 2025October 27, 2025Berkeley, This Week: Nanoscience

Kavli Affiliate: Xiang Zhang | First 5 Authors: Yu Yang, Yu Yang, , , | Summary: Interactive world models that simulate object dynamics are crucial for robotics, VR, and AR. However, it remains a significant challenge to learn physics-consistent dynamics models from limited real-world video data, especially for deformable objects with spatially-varying physical properties. To […]
