So University of Utah biologists, led by assistant professor Jamie Gagnon, tackled the problem by comparing two fish species: zebrafish, which can regenerate its heart, and medaka, which cannot.

This rare glimpse into the beating heart of a zebrafish offers a view of how blood flows into and out of its heart. Zebrafish have a heart and a circulatory system similar to that of humans, but with ...

Scientists at the Hubrecht Institute in the Netherlands have achieved a remarkable breakthrough in heart regeneration therapy. By utilizing a protein found in zebrafish, known as Hmga1 ...

A new fully automated in vivo screening system (AISS) has been developed to transform drug evaluation by enabling rapid, ...

Polystyrene nanoparticles are widely used in packaging, but their effects on organisms are unclear. Very little was known ...

The zebrafish is a good research stand-in for its fellow vertebrate, the human, because the two have many parts in common: brain, heart, liver, kidneys. And genome sequencing has shown that 84 ...

Preclinical drug evaluation, especially for cardiotoxicity, is a critical stage in the drug development process.

A new fully automated in vivo screening system (AISS) has been developed to transform drug evaluation by enabling rapid, precise, and non-invasive ...

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 ...
