Researchers from the University of Copenhagen have discovered an important phenomenon beneath the Arctic sea ice that was previously thought impossible. This phenomenon could have implications for the food chain and the carbon budget in the cold north.

A research team at the University of Cologne and University Hospital Cologne identifies a circuit in the brain that counteracts anxiety and helps to restore balanced behaviour. The result could contribute to developing treatment options for anorexia nervosa, one of the deadliest mental illnesses / publication in “Nature Neuroscience”

Dr Maria Santacà is a behavioral biologist who specializes in the study of animal cognition and perception. Her research at the Department of Behavioral & Cognitive Biology of the University of Vienna explores how visual illusions can reveal the evolutionary roots of perception, asking whether similarities and differences across species reflect shared ancestry and neural complexity, or unique adaptations to ecological and social environments. In a newly published Frontiers in Psychology article, she uses a trick of vision where identical circles appear larger or smaller, depending on the context, to investigate differences in perception. She studied this two very different species: guppies and ring doves. In the following guest editorial, she describes how not only how fish and birds perceive their worlds, but also how ecological pressures shape the evolution of perception.

Artificial intelligence (AI) technology is revolutionizing antimicrobial drug development. In response to increasingly severe antimicrobial resistance challenges, AI can efficiently predict pathogen evolutionary trends, identify potential drug targets, and accelerate compound design and optimization, thereby significantly shortening the development timeline for antimicrobial agents. This correspondence focuses on the applications of AI in phenotype-driven target identification and validation, rational molecular design, and lead compound optimization for antimicrobial drug development, while highlighting current limitations and providing perspectives on future directions.
