Diving deeper: Obesity and Anxiety, a scientific perspective
It seems that there is a relationship between poor mental health and obesity. But the exact reasoning is far from clear. Animal experiments can shed light on the situation

Breathe easy, a novel approach to monitoring respiratory activity in zebrafish
Researchers from the University of Heidelberg used DanioScope in a novel way to objectively measure breathing in zebrafish embryos and larvae.

Using zebrafish as an early warning system of neurotoxic substances
How can we use a zebrafish (Danio rerio) embryo model to detect possible neurotoxic chemical mixtures that are difficult to detect with normal chemical analyses?

Getting robust results: one zebrafish is not like the other
Zebrafish larvae locomotor behavior often has a high variability, which can have a big impact on your results. Still, it is one of the most used parameters. So how can you make your study more robust?
