Adolescence marks not only the period of physical maturation bridging childhood and adulthood, but also a crucial period for remodeling of the human brain. A Penn study reveals new patterns of ...

KANSAS CITY, MO – For a tiny embryo to grow into an entire fruit fly, mouse or human, the correct genes in each cell must turn on and off in precisely the right sequence. This intricate molecular ...

Self-organizing multicellular systems derived from mouse embryonic stem (mES) cells called gastruloids, which previously have been shown to mimic critical events of mammalian gastrulation, have been ...

The nervous system is incredibly complex and begins developing very early on in life, then goes on to be the last one finished. New work has described a pattern of organization among cells that create ...

The scientific perspective behind cell pattern formation involves observing both the commonly seen principles behind similar cell patterns seen in nature and the visible events of self-organization.

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 ...

Fingerprints are among the most distinctive features of human biology, serving as enduring identifiers for individuals and as windows into genetic and developmental processes. The three major ...
