Zebrafish are genetically similar to humans and are good models for human biology and disease. Now, researchers at Children's Hospital Boston have created a zebrafish that is transparent throughout ...

The human heart confounds logic by starting to beat before it is fully formed -- a developmental oddity shared by all vertebrate hearts. New research now reveals a related oddity: The valve needed for ...

A transposon-insertion method can trap and mutate genes while simultaneously revealing their spatiotemporal expression pattern, all in a conditional manner in the live, transparent zebrafish. With ...

progression in living organisms. Click on the image for a larger version. Hot on the heels of see-through frogs, researchers at Children's Hospital Boston have bred see-through zebrafish that put ...

New research in mice and zebrafish has uncovered the genetic signal needed to form and maintain the blood-brain barrier. The discovery could let scientists control the barrier’s permeability, ...

The lab of Leonard Zon, MD, at Boston Children's Hospital has long been interested in making blood stem cells in quantity for therapeutic purposes. Looking for a way to test for their presence in ...

Fast-breeding zebrafish, combined with fluorescent tagging, could be a powerful way to find new cancer drugs. This study tested >3,800 drugs in high-throughput fashion and found that retinoic acid, ...

NOTE: A link to videos of the developing heart is at end of the release. The human heart confounds logic by starting to beat before it is fully formed —a developmental oddity shared by all vertebrate ...
