Cell Membranes Are Way More Complicated Than You Think Nazzy Pakpour
Cell membranes are structures of contradictions. These oily films are hundreds of times thinner than a strand of spider silk, yet strong enough to protect the delicate contents of life: the cell’s watery cytoplasm, genetic material, organelles, and all the molecules it needs to survive. How does the membrane work, and where does that strength come from? Nazzy Pakpour investigates.
How Does the Rorschach Inkblot Test Work Damion Searls
