The Cultural Evolution of Human Goals

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Humans pursue remarkably diverse goals that vary over time and across cultures. These goals are both drivers and products of cultural evolutionary dynamics, yet most theories of cultural evolution have focused on the influence of culture on how individuals reach their goals, rather than on which goals they pursue.

Molecular Control of Neural Stem Cell Quiescence in the Adult Zebrafish Telencephalon: Established Mechanisms and an Integrative Hypothesis

open access: yesGlia, Volume 74, Issue 12, December 2026.
Adult zebrafish radial glia quiescence is controlled by at least four mechanisms: Notch3, BMP‐Id1, Nr2f1b and Midkine‐a. We propose these act as partially redundant inputs, biased along the antero‐posterior axis that set quiescence depth. ABSTRACT The zebrafish telencephalon is an excellent model for adult neurogenesis under physiological and ...

The Arabidopsis DREB2 genetic pathway is constitutively repressed by basal phosphoinositide-dependent phospholipase C coupled to diacylglycerol kinase in Arabidopsis thaliana

open access: yesFrontiers in Plant Science, 2013
Phosphoinositide-dependent phospholipases C (PI-PLCs) are activated in response to various stimuli. They utilize substrates provided by type III-Phosphatidylinositol-4 kinases (PI4KIII) to produce inositol triphosphate and diacylglycerol (DAG) that is ...

Ewing Sarcoma in Infants and Children Under 2 Years of Age: A French Retrospective Study

open access: yesPediatric Blood &Cancer, Volume 73, Issue 11, November 2026.
ABSTRACT Ewing sarcoma, the second most common primary bone cancer in children, requires intensive treatment that may lead to significant long‐term sequelae, particularly in infants. We retrospectively analyzed data from 1621 French patients treated between 1988 and 2015 within the EW88/93/97 or EE99 trials, focusing on 17 infants diagnosed before 24 ...
