Prehistoric shuttle dispersals in a Malthusian economy

open access: yesInternational Journal of Economic Theory, Volume 22, Issue 2, Page 147-160, June 2026.
Abstract Early humans undertook multiple waves of migration out of Africa and back to the continent. We explore prehistoric human migration in a two‐region Malthusian growth model. Whether migration occurs depends on the migration cost, relative population size, relative land supply, and relative hunting‐gathering productivity between regions.

Sleep Deprivation in Mice: Looking Beyond the Slow Wave Rebound

open access: yesJournal of Sleep Research, Volume 35, Issue 3, June 2026.
ABSTRACT Sleep is a fundamental process supporting the dynamic regulation of neural function. Emerging methods have proposed that the aperiodic components of brain signals (such as the spectral slope, spectral intercept, and spectral knee), in addition to entropy‐based measures, offer robust empirical markers of neural states.

Sleep Macrostructure, Cyclic Alternating Pattern and CSF Cytokines in De Novo Relapsing–Remitting Multiple Sclerosis: A Controlled Polysomnographic Study

open access: yesJournal of Sleep Research, Volume 35, Issue 3, June 2026.
ABSTRACT Multiple sclerosis is frequently associated with sleep disorders. This study aimed to evaluate subjective and objective sleep parameters in de novo relapsing–remitting multiple sclerosis patients compared to healthy controls and to explore correlations with cerebrospinal fluid cytokines.
