The decades-old anesthetic ketamine could be a game changer for treating severe depression, but there are still many questions about how the drug works, including exactly how it affects the brain's ...

The ability of some animals to dynamically change color to match the brightness of their surroundings is one of nature's great survival tools, allowing flatfish to blend into sandy seabeds, frogs to ...

The heart’s “mini-brain” is independent and highly localized, according to researchers at the Karolinska Institutet in Stockholm, Sweden. The findings could lead to new research into arrhythmia, ...

Researchers are turning to zebrafish to unlock the secrets of place cells, which play a crucial role in forming mental maps of space, social networks, and abstract relationships. Until now, place ...

While the structure of a zebrafish’s brain is significantly different than the structure of a human brain, they share many basic principles of organization and communication. Researchers study ...

On the left, identified organically bounded C-14 (OBC-14, red dots) in metabolites of zebrafish brain were labeled in the KEGG global pathway map. The blending of C-14 induced significant effects such ...

According to Stanford Medicine, microplastics and their smaller counterparts, nanoplastics, are everywhere - from our food to our water to our clothes and even the air we breathe. While research ...

A novel system that chases larval zebrafish around an arena with predator robots is enabling scientists to understand how these days-old fish quickly learn in the real world. A novel system developed ...

Learn more about nanoplastics and how easily they can get into the bloodstream of zebrafish, resulting in buildup in the brain and reproductive organs. According to Stanford Medicine, microplastics ...
