A team from the University of Geneva (UNIGE) has observed that this species forms multicellular structures that bear striking similarities to animal embryos. These observations suggest that the ...

Surprisingly, many of these multicellular-enabling genes had viral origins. The study, which increased the total number of ...

Each cell of the human body contains two meters of DNA. The whole secret lies in the intricate three-dimensional arrangement that allows DNA strands to be efficiently organized and compacted within ...

Skeletal muscles work in pairs to move the body. When you move your arm, the bicep contracts while the triceps muscle relaxes. The bicep pulls the bones together, bending the arm. The reverse ...

The fossil offers new insight into the transition of single celled organisms to complex, multicellular animals. Modern single-celled holozoa include the most basal living animals and the fossil ...

How does multicellularity evolve? Scientists who study a family of green algae that includes unicellular Chlamydomonas and multicellular Volvox are beginning to find answers to this question.

Cell division allows for growth and replacement of dead cells. Most multicellular organisms are made of different cell types that are specialised to carry out specific functions. Control and ...
