Research identifies earlier origin of neural crest cells

Neural crest cells—embryonic cells in vertebrates that travel throughout the body and generate many cell types—have been thought to originate in the ectoderm, the outermost of the three germ layers formed in the earliest ...

Embryo's early development revealed in a dish

During embryonic development, the entire nervous system, the skin and the sensory organs emerge from a single sheet of cells known as the ectoderm. While there have been extensive studies of how this sheet forms all these ...

Study answers longstanding cell-development riddle

During the lifetime of a body—whether human, fish or any other type of vertebrate—cells die, making room for fresh new cells to carry on vital processes. The dead cells must be cleared away, though, and debris removal ...

Chewing versus sex in the duck-billed dinosaurs

The duck-billed hadrosaurs walked the Earth over 90-million years ago and were one of the most successful groups of dinosaurs. But why were these 2-3 tonne giants so successful? A new study, published in Paleobiology, shows ...

How to make fish shine

Scientists from the University of Bath have helped to figure out why shoals of fish flash silver as they twist through the water by studying how the shiny silver cells are created in zebrafish.
