Neurogenesis and the Epigenetic Landscape: Role of Histone Modifications and Chromatin Remodeling

Brain and Behavior, Volume 16, Issue 2, February 2026.
Histone methylation and acetylation modulate gene expression by inducing chromatin condensation or relaxation, which in turn regulates transcriptional activity and impacts neurogenesis. ABSTRACT Aims The purpose of this review is to examine how epigenetic regulation particularly chromatin modification and histone methylation controls gene expression ...

Influence of reference genes on expression of TYR, MITF and ASIP genes in tissues of Silky Fowl

浙江大学学报. 农业与生命科学版, 2015
Silky Fowl is a precious local breed containing a large amount of melanin. Therefore, it is considered to have high edible and medicinal value. Study on the related gene expression is helpful to reveal the internal regulation mechanism of melanin ...

The Evolving Decline of Landfast Sea Ice in Northern Alaska and Adjacent Waters: Results from an Updated Climatology

Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.
Abstract We present a new 27‐year record of landfast sea ice extent in northern Alaska and adjacent waters, which uses ice chart data to extend a previous analysis based on synthetic aperture radar (SAR) imagery. This new climatology provides updated information on the decline of landfast ice in a region of the Arctic that has seen extensive losses of ...

Pan-Arctic sea ice concentration from SAR and passive microwave [PDF]

The Cryosphere
Arctic sea ice monitoring is a fundamental prerequisite for anticipating and mitigating the impacts of climate change. Satellite-based sea ice observations have been subject to intense attention over the last few decades, with passive microwave (PMW ...

In Situ Observation of a Strong Diurnal Warming Event in the Labrador Sea Undetected by Satellites

Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.
Abstract Diurnal warming (DW) at the ocean surface occurs when there is a combination of solar heating in the absence of vertical mixing typically derived from wind stress. DW has been well described, mostly from satellite data, but also with some in situ observations.

First documented observation of differential dorsoventral coat colouration in wild boar Sus scrofa (Artyodactyla: Suidae) in Italy

Natural History Sciences
Wild boar Sus scrofa usually shows a uniform brown coat, but different colour patterns have been observed with red, brown, black, and white morphs. Nevertheless, coat colour polymorphism is often associated with hybridization with domestic pigs.

Alteration of sheep coat color pattern by disruption of ASIP gene via CRISPR Cas9

Scientific Reports, 2017
Coat color is an important characteristic and economic trait in domestic sheep. Aiming at alteration of Chinese merino sheep coat color by genome manipulation, we disrupted sheep agouti signaling protein gene by CRISPR/Cas9.

Review of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) on Ten years of phytopharmacovigilance in France: Review of the only organisation of its kind in Europe for post‐MA vigilance of plant protection products

Food Risk Assess Europe, Volume 4, Issue 1, January 2026.
Abstract Phytopharmacovigilance consists in identifying signals of adverse effects on human, animal and plant populations and the environment associated with the use of plant protection products, and reporting them to the various bodies responsible for assessing and managing risks.

Single‐cell landscape of sex‐specific drivers of Alzheimer's disease

Alzheimer's &Dementia, Volume 21, Issue 12, December 2025.
Abstract INTRODUCTION We investigated sex‐specific gene expression associations with the neuropathology and cognitive manifestation of Alzheimer's disease (AD) leveraging single‐nucleus transcriptomic datasets including 2.84 million nuclei from the dorsolateral prefrontal cortex (DLPFC).
