The ‘fourth pillar’ of brain communication potentially impacts Alzheimer’s and other diseases. Brain cells are like tiny trees. They have an intricate web of roots that take in signals and a trunk...

Most cells in the body send out little messengers called extracellular vesicles that carry proteins, lipids, and other bioactive molecules to other cells, playing an important role in intercellular communication. But healthy cells are not the only ones that rely on extracellular vesicles. Cancer cells do, too. Small extracellular vesicles that are shed from tumor cells contribute to how cancer spreads to healthy tissue.

How cells utilize electric fields to guide their migration during embryonic development. As an embryo develops, cells constantly communicate to organize into tissues and organs. This process requires...
