IRB Barcelona Using Drosophila melanogaster, researchers at IRB Barcelona discover that during multiple cell migrations a single cell can act as leader, dragging the others with it. The migration of groups of cells in order to form tissues is common during the development of an organism. Discovering how these multiple movements are achieved is not only crucial to understand the basic principles of development but provides new information and insights for further research into processes...

For the first time, Tufts University biologists have reported that bioelectrical signals are necessary for normal head and facial formation in an organism and have captured that process in a time-lapse video that reveals never-before-seen patterns of visible bioelectrical signals outlining where eyes, nose, mouth, and other features will appear in an embryonic tadpole. The Tufts research with accompanying video and photographs will appear July 18 online in advance of publication in the...

Neurobiologists at UC San Diego have discovered new ways by which nerves are guided to grow in highly directed ways to wire the brain during embryonic development. Their finding, detailed in a paper in the February 15 issue of the journal Developmental Cell, provides a critical piece of understanding to the longstanding puzzle of how the human brain wires itself into the complex networks that underlie our behavior. The discovery concerns the movements of a highly sensitive and motile...

More than 80 years have passed since the German scientist Hans Spemann conducted his famous experiment that laid the foundations for the field of embryonic development. After dividing a salamander embryo in half, Spemann noticed that one half "“ specifically, the half that gives rise to the salamander's 'belly' (ventral) starts to wither away. However, the other 'back' (dorsal) half that develops into its head, brain and spinal cord, continues to grow, regenerating the missing belly...

In a story reminiscent of David and Goliath, new research from Rockefeller University shows that sometimes the smallest molecules can be the most powerful. In the July 1 issue of Cell, Ulrike Gaul, Ph.D., and colleagues report that microRNAs serve very important, and very specific, functions during the early development of the fruit fly. First discovered a few years ago, microRNAs are short strings of RNA that are made in large amounts in every cell from plant to humans. Biochemists,...
