Slowly rotating condensate dark stars beyond the mean-field approximation

Abstract We investigate rotational properties and universal relations of slowly rotating Bose–Einstein condensate dark stars in the context of General Relativity, both at the mean-field level and when the leading beyond-mean-field Lee–Huang–Yang correction is retained self-consis...

Beyond bactericidal surfaces: interfacial selectivity as a design principle for implant biomaterials

Within seconds of placement, an adsorbed conditioning film replaces the implant's manufactured substrate and becomes the true interface host cells and microorganisms encounter. Conventional strategies engineered to kill or suppress bacteria therefore act on an interface neither p...

Oleogels and Related Structured-Lipid Systems as Dual-Function Ingredients in Meat Products: Saturated Fat Replacement and Bioactive Delivery

Oleogels, in which liquid oils are structured into semi-solid matrices by oleogelators, have been widely investigated as animal fat replacers in meat products, where they lower saturated fatty acid content while helping preserve texture, structure, and emulsion stability. The rep...

Edible Fungi in Functional Aquafeeds: Prebiotic and Immunostimulatory Effects in Commercially Important Farmed Fish

Aquaculture faces structural constraints linked to input sustainability, animal health, and a persistent reliance on fishmeal and fish oil, alongside the intensive use of antibiotics in high-density production systems. In this context, edible fungi have emerged as promising funct...

The Resilient and the Vulnerable: Root-Associated Fungal Communities in the Regeneration of Nothofagus pumilio Forest Eight Years After Fire

Wildfires are increasing in frequency and severity worldwide, with long-lasting effects on forest vegetation and fungal communities essential for seedling establishment and forest resilience. Nothofagus pumilio, the dominant tree of South American temperate forests, forms key fun...

A large-scale in silico chimera-based strategy for engineering low-immunogenic L-asparaginase from Penicillium cerradense

L-asparaginase (L-ASNase) is an amidohydrolase with high therapeutic value for the treatment of acute lymphoblastic leukemia (ALL). However, its clinical application is limited by immunogenicity, allergenicity, and adverse effects from glutaminase activity. In this study, we engi...
