Developmental differences in cortical bone structure in chimpanzee and human femora reflect early locomotor independence in humans

The Anatomical Record, EarlyView.
Abstract The cortical bone structure of long bone diaphyses changes throughout growth via skeletal modeling and has important implications for bone strength and structural integrity. Ontogenetic trends in diaphyseal structure have been identified in both chimpanzees and humans but it is not yet clear how these trends compare given notable differences ...

Breeding bird response to season of burn in an upland hardwood forest

Forest Ecology and Management, 2019
Abstract Upland hardwood forest managers are increasingly burning during the growing-season in hopes of improving wildlife habitat and attaining or accelerating other restoration goals, highlighting the need for research addressing how season of burning affects wildlife, including breeding birds.

Postnatal craniomandibular growth in Harbor seals (Phoca vitulina vitulina)

The Anatomical Record, EarlyView.
Postnatal ontogeny in Harbor seals (Phoca vitulina vitulina). Cranium and mandible grow rapidly until 5 years of age, followed by a deceleration and finally a stagnation. Abstract As secondarily aquatic carnivores, seals display several phenotypic differences compared to their terrestrial relatives.

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

MicroRNA‐Seq Analysis Reveals a Critical Role for miR‐222 in Bovine Intramuscular Adipogenesis via the DDIT4/mTORC1 Axis

Animal Research and One Health, EarlyView.
Schematic diagram illustrating how miR‐222 promotes bovine intramuscular adipogenesis by targeting DDIT4 to activate the mTORC1 signaling pathway. ABSTRACT Intramuscular fat (IMF) is a key determinant of beef quality, particularly with respect to tenderness, flavor, and juiciness.

Comparative Analysis of Salmonella typhimurium‐Induced Transcriptomic Changes in the Spleen of Beijing‐You Chickens and Guang Ming Broilers

Animal Research and One Health, EarlyView.
This study analyzed the spleen transcriptomes of different chicken breeds, identified key differentially expressed genes (EGR1, FOS, and DUSP1) that regulate resistance to Salmonella infection, and elucidated the underlying regulatory mechanisms, thereby providing new targets for disease‐resistant breeding in poultry.

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

Astronomische Nachrichten, EarlyView.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.
