Two cis-regulatory SNPs upstream of ABCG2 synergistically cause the blue eggshell phenotype in the duck.

PLoS Genetics, 2020
Avian eggshell color is an interesting genetic trait. Here, we report that the blue eggshell color of the domestic duck is caused by two cis-regulatory G to A transitions upstream of ABCG2, which encodes an efflux transporter.

Microemulsion‐Based Drilling Fluids Incorporating Seashell Residue Powder: A Sustainable Approach to Fluid Loss Control

Journal of Surfactants and Detergents, EarlyView.
Two microemulsion‐based drilling fluids incorporating SSRP were formulated using pine oil, the nonionic surfactant Alkonat L100W, and a glycerol/water solution. The results provide valuable insights into how surfactant‐assisted microemulsion systems can be engineered to enhance the performance and eco‐efficiency of drilling fluids.

How I Do It: Two Novel, Low‐Cost Phonomicrosurgery Models With Open‐Source, 3D‐Printed Laryngoscopes

The Laryngoscope, EarlyView.
Two new vocal fold microflap models using products found in any grocery store have been developed along with publicly available 3D‐printable parts for simulating multiple laryngoscopes commonly used during laryngeal phonomicrosurgery. This represents a low cost, easily reproducible model for basic laryngeal phonomicrosurgery training.

From the brink of extinction to regulation: northern Europe's white‐tailed eagles now face density dependence and climate constraints after rapid population growth

Oikos, EarlyView.
Population growth reflects the combined influence of regulation and density‐independent factors operating through demographic processes. Under exceptional circumstances (e.g. populations recovering from near‐extinction), growth may initially be weakly regulated but typically slows as negative density dependence (NDD) sets in.

The first description of dinosaurian eggshell from the Maastrichtian Lance Formation, Wyoming, North America [PDF]

Acta Palaeontologica Polonica
Although numerous fossils have been excavated and described from the Upper Cretaceous (Maastrichtian) Lance Formation, eggs and eggshell remains are rare and have yet to be described in detail.

Improvement of water absorption behavior and mechanical properties of woven jute fiber‐reinforced epoxy composites with waste eggshell filler

Polymer International, EarlyView.
This study investigates the influence of waste eggshell powder on the water absorption and mechanical properties of jute fiber‐reinforced epoxy composites. Optimal eggshell filler content (2 wt%) significantly enhances composite performance by reducing water absorption and improving mechanical properties.

Investigation of the Mechanical, Thermal, and Morphological Properties of ABS Composite Reinforced With Bentonite and DEHPA‐Modified Bentonite

Journal of Polymer Science, Volume 63, Issue 6, Page 1505-1517, 15 March 2025.
Mechanical and thermal properties of ABS/Bentonite/DEHPA composites. ABSTRACT This study investigates the mechanical, thermal, and surface characteristics of acrylonitrile–butadiene–styrene (ABS) composites reinforced with bentonite and bis(2‐ethylhexyl) phosphate (DEHPA)‐modified bentonite.

Hydropower Operations Reduce Alluvial Nesting Habitat and Alter Riverine Turtle Population Demographics

River Research and Applications, EarlyView.
ABSTRACT Hydropower management has altered discharge regimes of large rivers worldwide, reducing sediment mobilization and early‐seral conditions essential for many riverine species. Spiny softshell turtles (Apalone spinifera) rely on alluvial habitats for nesting and may serve as sentinel species to assess the effects of regulated flow regimes and ...
