Kavli Affiliate: Rudolf Podgornik | Summary:Proteinaceous shells useful for various biomedical applications exhibit a wide range of anomalous structures that are fundamentally different from icosahedral viral capsids described by the Caspar-Klug paradigmatic model. Exploring the Protein Data Bank, we have identified nine different types of anomalous shells structurally close to flat octagonal quasicrystals. As we […]
Kavli Affiliate: Debora Sijacki | Summary:We review the state of the evidence for the existence and observational appearance of supermassive black hole binaries. Such objects are expected from standard hierarchical galaxy evolution to form after two galaxies, each containing a supermassive black hole, have merged, in the centre of the merger remnant. A complex interaction […]
Kavli Affiliate: Anton Akhmerov | Summary:To observe Majorana bound states, and especially to use them as a qubit, requires careful optimization of competing quality metrics. We systematically compare Majorana quality in proximitized semiconductor nanowires and quantum dot chains. Using multi-objective optimization, we analyze the fundamental trade-offs between topological gap and localization length, two key metrics […]
Kavli Affiliate: Jacqueline Hewitt | Summary:Observations of the redshifted 21-cm line during the Epoch of Reionization will open a new window to probe the intergalactic medium during the formation of the first stars, galaxies, and black holes. A particularly promising route to an initial detection is to cross-correlate tomographic 21-cm maps with spectroscopically confirmed Lyman-$α$ […]

Kavli Affiliate: Jin Kang | Authors: Abdullah Ozer, Jin Joo Kang, Yuliang Tang, Kumar Yugandhar, Yu Sun, Michael D DeBerardine, Karim Omar, John Lis and Haiyuan Yu | Summary: RNA Polymerase II (Pol II) transcription is highly regulated at two early steps in the transcription cycle: Pre-Initiation Complex (PIC) assembly with its coupled initiation, and […]
Kavli Affiliate: Sara Seager | Summary:Young accreting planetary-mass objects are thought to draw material from a circumplanetary disk (CPD) composed of gas and dust. While the gas within the disk is expected to disperse within the first million years, strong accretion has nonetheless been detected in older systems, including the 30–45 Myr-old planetary-mass companion Delorme […]

Kavli Affiliate: Morteza Gharib| Summary:Fixed-wing unmanned aerial vehicles (UAVs) offer endurance and efficiency but lack low-speed agility due to highly coupled dynamics. We present an end-to-end sensing-to-control pipeline that combines bio-inspired hardware, physics-informed dynamics learning, and convex control allocation. Measuring airflow on a small airframe is difficult because near-body aerodynamics, propeller slipstream, control-surface actuation, and […]
