Kavli Affiliate: Justus M Kebschull and Jean Fan | Authors: Manjari M-G Anant, Eli Clemens Zuercher, Maggie Lowman, Caleb Shi, Dylan Z. Faltine-Gonzalez, Michael L. Piacentino, Jean Fan and Justus M. Kebschull | Summary: The cerebellar nuclei, the output regions of the cerebellum, have evolved via repeated duplication of a conserved cell type set to […]
Kavli Affiliate: Robert B. Darnell | Authors: Madison T Jones, Natalie Noble, Robert B Darnell and Ezgi Hacisuleyman | Summary: Neurons rely on localized protein synthesis to rapidly adapt synaptic function to activity, yet how dendritic translation regulates mitochondrial remodeling during synaptic plasticity remains poorly understood. Here, we show that neuronal activity engages a spatially […]
Kavli Affiliate: Gregory Herczeg | Summary:Hydrogen lines are widely used as tracers of stellar and planetary accretion. In classical T~Tauri stars, hydrogen lines are usually interpreted as arising from magnetospheric accretion columns, whereas in lower-mass counterparts (subsolar-mass objects including brown dwarfs and gas giant planets), the post-accretion-shock region can directly emit a substantial fraction of […]
Kavli Affiliate: Wei Gao| Summary:Reactive vision-language-action (VLA) policies suffer from task-state aliasing in long-horizon manipulation, where identical multimodal inputs call for distinct, context-dependent actions. Given that pretrained VLAs already possess rich control primitives to express diverse behaviors, we hypothesize that the execution bottleneck lies not in policy capacity, but in input ambiguity. In this paper, […]

Kavli Affiliate: Wei Gao| Summary:Reactive vision–language–action (VLA) models struggle with long-horizon manipulation when visually similar observations can correspond to different actions depending on the task stage or interaction history. We refer to this ambiguity as task-state aliasing and introduce TaskAnchor, a lightweight adapter that grounds pretrained VLAs in execution history. TaskAnchor combines history-conditioned visual refinement […]
Kavli Affiliate: Luis Ho | Summary:The cosmic evolution of galactic bars offers key insights into the dynamical history of disk galaxies. However, studies of high-redshift bars are severely hampered by observational effects such as resolution degradation and surface brightness dimming. To quantify these biases and establish a robust methodology of bar detection and measurement for […]
