Four graphs show the patterns of gene expression at 4 time points during early drosophila embryo development. The spatial distributions of gene expression are represented in line plots for each ...

This looks like a “little purple pill” but is actually a fruit fly embryo undergoing a wave of cell division, traveling from one end of the embryo to the other. Look closely and try to guess which ...

In both humans and fruit flies, the heart's tissues arise from two distinct regions of the embryo, which are initially far apart. As development progresses, these cells journey toward each other, ...

These side-by-side time-lapse videos offer a detailed view of how cells move in a growing fruit fly embryo and of how its nervous system develops and organizes. This is a side-by-side time-lapse video ...

Thomas Hunt Morgan has now been studying flies in his "fly laboratory" at Columbia University for two years. Day after day, the trained geneticist feeds thousands of these insects, a mere three ...

Outwardly, fruit flies and humans have little in common. It is all the more astonishing that roughly 60 percent of the fly's genes can also be found in humans in a similar form. Many insights gained ...

Researchers have identified a previously undescribed neurological syndrome that causes intellectual disability in humans. They also confirmed that a similar gene defect has effects on neural ...

As far back as the 19th century it was apparent to some biologists that a simple, repeated pattern underlay the differing body structures of animals. It could be seen in the segmented bodies of ...
