Researchers confirm using zebrafish that if a certain gene is not excluded when vertebrate embryos are developing, the notochord will not elongate properly, resulting in a shortened form. Can a single ...

Researchers at the National Institutes of Health have published an atlas of zebrafish development, detailing the gene expression programs that are activated within nearly every cell type during the ...

How can we reliably and objectively characterize the speed and various stages of embryonic development? With the help of artificial intelligence! Researchers present an automated method. Animal ...

Over half of our genomes consist of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the "dark side" of the ...

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ...

This paper presents an important advance in genetically encoded voltage imaging of the developing zebrafish spinal cord in vivo, capturing voltage dynamics in neuronal populations, single cells, and ...

Nearly half the embryos studied underwent developmental arrest because of genetic mishaps in early development—a revealing insight that suggests more IVF babies could come to term with changes in the ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...
