Every multicellular organism, from tiny worms to humans, elephants, and whales, needs a way for their cells to connect with each other to form tissues, organs, and organize their overall body plan.

In fact, why and how multicellular life evolved has long puzzled biologists. The first known instance of multicellularity was about 2.5 billion years ago, when marine cells (cyanobacteria) hooked up ...

For some three billion years, unicellular organisms ruled Earth. Then, around one billion years ago, a new chapter of life began. Early attempts at team living began to stick, paving the way for the ...

Mount Sinai researchers have published the first organ-wide human skin spatial atlas from across the body. It provides an ...

Images of the multicellular development of the ichthyosporean Chromosphaera perkinsii, a close cousin of animals. In red, the membranes and in blue the nuclei with their DNA. The image was obtained ...

In a groundbreaking experiment, researchers have brought a mouse to life with the help of a single-celled organism that existed long before any multicellular animals walked the earth. Genetic research ...

Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single cells and forming multicellular structures. This ability to alternate ...

UC Davis researchers Gant Luxton, Daniel Starr and Xiangyi Ding have used tiny fluorescent particles to study what is going on inside the cells of Caenorhabditis worms. They found that the cells are ...

WOODS HOLE, Mass. -- Humans like to think that being multicellular (and bigger) is a definite advantage, even though 80 percent of life on Earth consists of single-celled organisms – some thriving in ...
