Discouraged zebrafish help reveal how ketamine works in the brain. The decades-old anaesthetic ketamine could be a game changer for treating severe depression, but there are still many questions about […]
Zebrafish testing identifies a gene potentially at the root of domestication. Researchers at Queen Mary University of London have shown that zebrafish can provide genetic baz1b clues to the evolution of social […]
Zebrafish personaility pairing improves the fitness of the species. Scientists have challenged the theory of “love at first sight” after discovering that they can boost the reproductive success of zebrafish […]
Seeing the future: Zebrafish regenerates fully functional photoreceptor cells and restores its vision. Blinding diseases lead to permanent vision loss by damaging photoreceptor cells, which humans cannot naturally regenerate. While […]
How many fish constitute a school? Physicists are also interested in fish — above all when they are researching the formation of structures. A research team from Heinrich-Heine University Duesseldorf […]
Sleep-wake rhythm: Fish change our understanding of sleep regulation. Contrary to common belief, not all vertebrates regulate their sleep-wake rhythm in the same way. University of Basel researchers have discovered […]
Fish display distinct individual behaviours when swimming to find food. Fish from the same species can evolve their sense of smell and display individual foraging ‘personalities’ to successfully find food […]
Why fish look down when they swim. Quirky behaviour helps fish estimate swimming direction and speed, simulations show. Just as you might look down at the pavement as you walk, […]
