Eastern Imperial Eagle in the Moyinqum Sands, Kazakhstan
Raptors Conservation, 2023 The Imperial Eagle (Aquila heliaca) is a rare breeding species of Kazakhstan. Previously, it was assumed that one of the large nesting groups of this species, and the most southeastern one in the range, is concentrated in the Moyinqum Sands and adjacent semi-desert areas in the south of Kazakhstan.

Steppe Eagle Population Structure Genetic Study: is There Hope for the Endangered Species?
Пернатые хищники и их охрана, 2023 For centuries, Steppe Eagle (Aquila nipalensis) had been the most numerous Palearctic Aquila species, but nowadays it has been decreasing in numbers progressively, so in 2015 the IUCN changed the species status to “endangered”.

Molecular Oncology, EarlyView.Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Autonomous Navigation of Pollen‐Inspired Magnetic Microrobots for Biomedical Applications
Advanced Robotics Research, EarlyView.A sunflower pollen‐inspired magnetic microrobot enables controlled rolling navigation in vessel‐like environments. Its open geometry reduces hydrodynamic drag, while vision‐based closed‐loop control, shortest‐path planning, and reinforcement learning support target‐reaching and maze navigation with microrobot‐scale accuracy, highlighting a route toward

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Regulation of Growth in Red Kites and Imperial Eagles
, 1997 We analyzed variability in growth of Red Kite (Milvus milvus) chicks using biometrical measures and urea and alkaline phosphatase blood levels. We used variables estimating relative mass and tarsus length growth rates during the 5-7 days before every blood extraction (short-term growth) and deviations of size (mass and tarsus length) from population ...
