Tight junctions (blue dots) between cells are connected areas of the plasma membrane that stitch cells together. Adherens junctions (red dots) join the actin filaments of neighboring cells together.

Both cell junctions and cytoskeletal networks help stabilize tissue architecture. For instance, the cells that make up human epithelial tissue attach to one another through several types of ...

Once the bottom layer has gained extra electrons, it becomes negatively charged at the junction; at the same time, the top layer has gained a positive charge there. Now the cell is ready for the sun.

In biology textbooks, the endoplasmic reticulum is often portrayed as a distinct, compact organelle near the nucleus, and is commonly known to be responsible for protein trafficking and secretion. In ...

Cancer that starts here is called gastro oesophageal junction (GOJ) cancer. It might also be called oesophago gastric junctional cancer. Cancer is when abnormal cells start to divide and grow in an ...

Scientists led by Saudi Arabia’s King Abdullah University of Science and Technology (KAUST) have fabricated a perovskite-perovskite-silicon triple-junction solar cell with a new passivation ...
