A heart attack will leave a permanent scar on a human heart, yet other animals, including zebrafish, can clear cardiac scar tissue and regrow damaged muscle as adults. Biologists sheds new light on ...

Researchers from the Hubrecht Institute and their collaborators at other institutions have used a protein from zebrafish dubbed Hmga1 which plays a key role in heart regeneration, to reactivate heart ...

An uninjured (left) and injured adult zebrafish heart with neural crest cells labeled magenta. Note the neural crest cells activated around the edge of the injury in preparation for regenerating the ...

Artistic representation of heart regeneration: Hmga1 in green symbolically flows from the border zone of a zebrafish heart (top right) to the injured border zone of a mouse heart (left). Red ...

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, ...

The zebrafish has emerged as a robust vertebrate model for studying cardiac electrophysiology and pharmacology, owing to its genetic tractability, optical transparency during early stages, and ...

A cross-department collaboration headed by researchers at Harvard Medical School and Harvard University has witnessed the moment at which cells in the zebrafish embryo heart start beating in unison ...

The 2025 NCAA Outdoor Track and Field Championship came to a close on Saturday with Georgia securing the women’s national title. Sixteen... Alex Akerberg places a specimen gently onto the operating ...

The human heart beats 60-100 times a minute, without you needing to pay any attention to it. Heart function is controlled by the brain’s autonomic nervous system (the parasympathetic and sympathetic ...

While this may look like a fiery sun rising out of a sea of blue jellybeans, it’s actually a section of a zebrafish heart and its surrounding tissues. While this may look like a fiery sun rising out ...
