Electrical Synapses Contribute to Sleep‐Dependent Declarative Memory Retention

open access: yesEuropean Journal of Neuroscience, Volume 63, Issue 2, January 2026.
Blocking electrical synapses (gap junctions) in healthy humans by mefloquine impaired the sleep‐dependent retention of verbal declarative memory and improved sensorimotor memory consolidation irrespective of sleep. Mefloquine also disrupted the coupling of sleep spindles to EEG slow oscillations in humans but did not affect hippocampal sharp‐wave ...

The Nature, Structure, and Perception of Illumination

open access: yesPhilosophy and Phenomenological Research, Volume 112, Issue 1, Page 175-192, January 2026.
ABSTRACT Illumination is a defining characteristic of natural environments, yet its nature and spatial structure remain poorly understood. I argue first that illumination is not simply light: it is an emergent, ecologically significant kind. Illumination has features not possessed by light, and contains self‐organizing structures that persist through ...

Scissors congruence K$K$‐theory for equivariant manifolds

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract We introduce a scissors congruence K$K$‐theory spectrum that lifts the equivariant scissors congruence groups for compact G$G$‐manifolds with boundary, and we show that on π0$\pi _0$, this is the source of a spectrum‐level lift of the Burnside ring‐valued equivariant Euler characteristic of a compact G$G$‐manifold.

Plank theorems and their applications: A survey

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract Plank problems concern the covering of convex bodies by planks in Euclidean space and are related to famous open problems in convex geometry. In this survey, we introduce plank problems and present surprising applications of plank theorems in various areas of mathematics.
