Flaws emerge in modeling human genetic diseases in animals

My lab, based at the University of Southern California Keck School of Medicine, uses zebrafish to model human birth defects affecting the face. When I tell people this, they are often skeptical that fish biology has any relevance ...

How mutant zebrafish helped unlock the secret to their stripes

Zebrafish are one of the most well studied animals on the planet. But how they came by their beautiful black and gold stripes is more of a mystery. Our new research used mathematical modeling—and detailed observations of ...

How the zebrafish got its stripes

Animal patterns—the stripes, spots and rosettes seen in the wild—are a source of endless fascination, and now researchers at the University Bath have developed a robust mathematical model to explain how one important ...

Study connects specific genes with defective social behavior

Animals rely on group behavior to survive, whether it's fish swimming together to avoid predators or humans sharing knowledge with each other. But despite the importance of such social interactions, scientists do not have ...

Special cells contribute to regenerate the heart in zebrafish

It is already known that zebrafish can flexibly regenerate their hearts after injury. An international research group led by Prof. Nadia Mercader of the University of Bern now shows that certain heart muscle cells play a ...
