Proper embryonic development of the fruit fly Drosophila melanogaster is governed by patterns of protein activity bequeathed to the fertilized egg by its mother. While the embryo is still a single ...

Optic flow is a large-field visual motion pattern that appears in human sight during movement and is a strong cue to perceive and control a person’s locomotor action 1,2,3,4,5. For instance, when a ...

Scientists have long observed that embryos of different species within a phylum look quite distinct at early and late developmental stages but resemble one another more during mid-embryogenesis, a ...

Patterns that guide the development of feathers and other features can be set by mechanical forces in the embryo, not just by gradients of chemicals. One of the longest-standing questions in biology ...

Despite often being portrayed as creatures that have remained virtually unchanged for millions of years, a new Harvard study shows crocodiles have repeatedly altered their developmental patterns, ...

In developmental cell biology, the phrase “pattern formation” is used in reference to the propagation of complex organizations of cell fates in time and space. Pattern formation is mainly controlled ...

Princeton researchers discover that multiple early developmental programs in the fly are governed by different thresholds of Ras/Erk signaling Proper embryonic development of the fruit fly Drosophila ...
