The Ontogenetic Development of Rapid Eye Movement Sleep in Early Life and Its Regulatory Mechanisms

open access: yesInternational Journal of Developmental Neuroscience, Volume 86, Issue 1, February 2026.
REM sleep was first identified in humans and cats in the late 1950s and exhibits a conserved developmental trajectory across species. This study elucidates key characteristic changes during REM sleep development, thereby providing a foundation for improving the prevention and treatment of various neurodevelopmental disorders.

Suckling of dairy calves by their dams : consequences on performance, feeding behavior and animal welfare

open access: yes, 2022
In most European dairy farms, calves are usually separated from their dams immediately or within few hours after birth. They are housed in individual pens for 1 or 2 weeks, then male calves are generally sold to be fattened in specialized farms and female calves, which are the future replacement heifers, are reared in multiple pens.

Chrysin Exhibits Bone‐Protective Effects Through Osteoclastogenesis Inhibition: In Vitro and In Vivo Evaluation in RAW 264.7 Murine Macrophages and Sprague–Dawley Rats

open access: yesMolecular Nutrition &Food Research, Volume 70, Issue 3, 13 February 2026.
The effects of chrysin, a plant‐derived compound, were investigated on osteoclast formation in cell culture and bone health parameters in Sprague–Dawley rats. Chrysin was shown to disrupt key osteoclast signaling pathways and inhibit osteoclast formation. Furthermore, chrysin moderately improved bone health parameters in the rats.

Targeted Next‐Generation Sequencing of the Leptin‐Melanocortin Pathway in Severe Obesity

open access: yesObesity, Volume 34, Issue 2, Page 499-511, February 2026.
ABSTRACT Objective Pathogenic variants in five established leptin‐melanocortin pathway genes (LEP, LEPR, MC4R, PCSK1, POMC) are associated with severe early‐onset obesity and are targets for emerging treatments. However, these variants are rare in these patients, suggesting the involvement of additional genes interacting with this pathway. Methods Next‐

Have the environmental benefits of insect farming been overstated? A critical review

open access: yesBiological Reviews, Volume 101, Issue 1, Page 163-194, February 2026.
ABSTRACT Insect farming is frequently promoted as a sustainable food solution, yet current evidence challenges many environmental benefits claimed by industry proponents. This review critically examines the scientific foundation for assessing the environmental impacts of insect farming in both human food and animal feed applications.
