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 ...

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 ...

A solar cell is made of two types of semiconductors ... of positively charged holes (which are vacancies due to the lack of valence electrons). Near the junction of the two layers, the electrons on ...

Developed by scientists in Germany, the triple-junction cell is based on a perovskite top cell with an energy bandgap of 1.84 eV, a perovskite middle cell with bandgap of 1.52 eV, and a silicon ...
