Developing nanomedicines with enhanced activity to scavenge reactive oxygen species (ROS) has emerged as a promising strategy for addressing ROS-associated diseases, such as drug-induced liver injury. However, designing nanozymes that not only remove ROS but also accelerate the repair of damaged liver cells remains challenging. Here, a two-pronged black phosphorus/Ceria nanozyme with mitochondria-targeting ability (TBP@CeO) is designed.

Cadmium (Cd) pollution is a growing concern worldwide, because it threatens human health through the food chain. Woody plants, such as the pioneer species black locust (Robinia pseudoacacia L.), are widely used in phytoremediation of Cd-contaminated soils, but strongly differ in Cd tolerance.

The success of introduced species often relies on flexible traits, including immune system traits. While theories predict non-natives will have weak defences due to decreased parasite pressure, effective parasite surveillance remains crucial, as infection risk is rarely zero and the evolutionary novelty of infection is elevated in non-native areas. This study examines the relationship between parasite surveillance and cytokine responsiveness in native and non-native house sparrows, hypothesizing that non-natives maintain high pathogen surveillance while avoiding costly inflammation.

Introduction: Vitex L. is a large genus of tropical and subtropical trees used in medicine of many nations. Some species are used in gynecology due to flavonoids, iridoids, and diterpenes.

The signals that mediate mate choice can be complex, comprising multiple components, and understanding how complex signals evolve under sexual selection has been the focus of much study. However, open questions still remain about the role of the female's sensory and perceptual processes in shaping the evolution of complex signals. Male green swordtails have an elongated caudal fin that comprises colour, length and a black melanic margin; females prefer males with larger bodies, longer swords and complete black sword margins.
