As the nation reckons with the assassination of conservative activist Charlie Kirk, there has been a notable trend from mainstream pundits and press outlets. They have tended to downplay or outright ignore the ugly things that he said and instead to stress the polite ways he said them. It's an

Rich Americans are spending at a higher rate this year
— everyone else is basically slowing their roll.
New data makes clear that while the good times continue for higher-income earners
— strong wage growth, less debt
— lower-income Americans are under increasing financial stress.

Lower-income Americans are under increasing financial stress.

The invariance of group occupation across the cosmic web
Recent efforts to identify secondary variations in the Halo Occupation Distribution (HOD) have primarily focused on simulations examining the role of large-scale cosmic environments such as superclusters, filaments, and underdense regions or voids. If present, these variations could yield valuable insights into galaxy formation mechanisms, halo assembly processes, and the influence of external factors on cosmic structure. We aim to test whether secondary trends in the HOD driven by the large-sc…

Gödel-type universes in unimodular gravity
In this paper, the Gödel-type universes are examined within the framework of unimodular gravity. Since the existence of Gödel solutions is intrinsically related to the presence of a cosmological constant in general relativity, one can naturally wonder how the acausal structure of the Gödel solutions behaves in different cosmological scenarios. One of the simplest, but important, frameworks within this context is the unimodular gravity, in which the cosmological constant emerges as an integra…

Hippocampal Plasticity and Navigational Skills in Blindness

Navigation is a fundamental cognitive ability that relies on the hippocampus, a brain region that is known for its role in spatial representation and memory. In individuals with congenital blindness, the absence of visual input leads to significant neuroplastic adaptations that support alternative navigation strategies. This review examines the structural and functional modifications of the hippocampus in individuals who are blind and explores the broader neural mechanisms underlying…

Why does your graph neural network fail on some graphs? Insights from exact generalisation error
Graph Neural Networks (GNNs) are widely used in learning on graph-structured data, yet a principled understanding of why they succeed or fail remains elusive. While prior works have examined architectural limitations such as over-smoothing and over-squashing, these do not explain what enables GNNs to extract meaningful representations or why performance varies drastically between similar architectures. These questions are related to the role of generalisation: the ability of a model to make acc…

A Tale of Two Mobile Generations: 5G-Advanced and 6G in 3GPP Release 20
As the telecommunications industry stands at the crossroads between the fifth generation (5G) and sixth generation (6G) of mobile communications, the 3rd generation partnership project (3GPP) Release 20 emerges as a pivotal point of transition. By striking a balance between enhancing 5G-Advanced capabilities and setting the stage for 6G, Release 20 provides the crucial foundation upon which future mobile communication standards and deployments will be built. This article examines these dual obj…

Structural Characterizations of Marginal Policy Effects
This paper investigates the structural interpretation of the marginal policy effect (MPE) within nonseparable models. We demonstrate that, for a smooth functional of the outcome distribution, the MPE equals its functional derivative evaluated at the outcome-conditioned weighted average structural derivative. This equivalence is definitional rather than identification-based. Building on this theoretical result, we propose an alternative identification strategy for the MPE that complements existi…

Causal structure and topology change in (2+1)-dimensional simplicial gravity
We develop a systematic method for analyzing the causal structure at vertices in (2+1)-dimensional Lorentzian simplicial gravity. By examining the intersection patterns of lightcones emanating from a vertex with its simplicial neighbourhood, we identify 13 distinct causal types of Lorentzian tetrahedra-excluding configurations with null faces. This forms the basis for a topological classification of the local causal structure in terms of the number of connected spacelike and timelike regions on…
