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 themselves into a variety of tissues and organs, such ...

Researchers propose that placozoans, one of the simplest kinds of animals, may contain the blueprint for the neurons of more complex creatures. By Sam Jones For hundreds of millions of years, pancake-shaped animals about the size of a sharp pencil tip have ...

A virtual cell modeling system, powered by AI, will lead to breakthroughs in our understanding of diseases, argue the cofounders of the Chan Zuckerberg Initiative. As the smallest living units, cells are key to understanding disease—and yet so much about ...

Cancer is a disease that causes abnormal cells to reproduce and spread to other parts of the body, which can result in tumors or damage to the immune system that may become fatal. Healthy cells follow a cycle of growing, dividing, and dying. Cancer cells ...

Scientists at DKFZ and Heidelberg University Hospital discovered that brain grid cells, once thought to act as a fixed GPS, actually switch between different local reference points depending on the situation.

Georgia Tech and Vanderbilt researchers have built the first lung-on-a-chip with a working immune system, a breakthrough with the potential to reshape how we study disease, move beyond animal testing,
