Sleep Soundly: New Insights Could Pave the Way for Novel Treatments for Insomnia
Texas A&M biologist Alex Keene and his team used variant-to-gene mapping, a predictive genomics approach, to demonstrate that the gene Pig-Q plays a role in…
Researchers Have Uncovered New Functions of the “Ancient Brain”
A multiregional hindbrain circuit enables animals to regain their pathing after deviating from it. A zebrafish heads toward its target, but strong currents push it…
Scientists Uncover a Gut-Brain Connection for Social Development
To learn to socialize, zebrafish need to trust their gut. Gut microbes encourage specialized cells to prune back extra connections in brain circuits that control…
Scientists Discover That the “Love Hormone” Could Actually Heal Your Heart
Researchers have found that oxytocin, sometimes known as the “love hormone,” may one day help heal damaged hearts after a heart attack. The neurohormone oxytocin is…
What Happens in the Brain When It’s Too Hot?
Zebrafish experiments demonstrate how vulnerable freshwater and marine species may be impacted by climate change. When the climate changes, which organisms survive and which die?…
Scientists Identify a Unique Set of Proteins That Restore Hearing
A study demonstrates how transcription factors support cell regeneration. Researchers at the National Institutes of Health have identified a particular protein network that is necessary…
How a Certain Animal Can Regenerate a Broken Heart
Zebrafish may repair heart tissue after injury, according to research conducted by the MDC team under the direction of Jan Philipp Junker and Daniela Panáková….
“Single Pixel Vision” Discovery in Fish Reveals Clues to How Humans Can Spot Tiny Details
Recently discovered ‘single-pixel vision’ in fish could help researchers understand how humans are able to spot tiny details in their environment — like stars in…
Scientists Reveal Genetic Roadmap to Building an Entire Organism
Whether a worm, a human, or a blue whale, all multicellular life begins as a single-celled egg. From this solitary cell emerges the galaxy of…
Magnetoreception – A Compass In The Dark
A research team headed by scientists of Helmholtz Zentrum München and the Technical University of Munich (TUM) has published a new model in ‘Nature Communications’…
Key Process in Brain Development Identified
By studying miR-107 in zebrafish, Yale researchers have discovered that miR-107 plays a key role in early brain development, and perhaps in the development of…
Zebrafish Larva Eye Distinguishes Between Prey and Predator
A new study from the Max Planck Institute for Medical Research reveals how the eye of a zebrafish larva can already distinguish between prey and…
Scientists Uncover How Beautiful Color Patterns Develop in Zebrafish
Scientists at the Max Planck Institute have discovered how pigment cells arise and interact to form the ‘zebra’ pattern in zebrafish. The zebrafish, a small…
Researchers Identify Molecular Factors that Push the Domino of Life into Motion
In a newly published study, Yale University geneticists report that three factors — Nanog, Pou5f1 (or Oct4) and SoxB1 — are indeed needed to push…
Artificial-Enzyme Editing Rewrites Zebrafish DNA, Could be Useful in the Study of Diseases
Zebrafish (Danio rerio) are a useful model for studying gene behavior and function. Researchers have been able to make custom changes in the zebrafish’s genome,…
