A recent study by Ruibao Li and Jennah Dharamshi published in Nature may help us understand the beginnings of animal ...

One of the biggest quests in biology is understanding how every cell in an animal’s body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A ...

Animal cell types are defined by differential access to genomic information—a process orchestrated by the combinatorial activity of transcription factors that bind to cis-regulatory elements (CREs) to ...

Five animal species can rebuild organs, limbs, and tissues that most vertebrates permanently lose after injury. Planarians regrow entire bodies from tiny fragments using adult pluripotent stem cells ...

Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells arrange ...

This fluorescence image shows chloroplasts (magenta colored) successfully incorporated into the hamster cells, with other features of the animal cell also highlighted (nuclei in light blue and ...

Camera-type eyes in vertebrates and cephalopods are striking examples of parallel evolution of a complex structure. While comparisons have focused on these two groups, camera-type eyes with likely ...
