Cells lining the blood vessel walls
The structure of the endothelium, the thin layer of cells that line our arteries and veins, is visible here. The endothelium is like a gatekeeper, controlling the movement of materials into and out of the bloodstream. Endothelial cells are held tightly together by specialized proteins that function like strong ropes (red) and others that act like cement (blue).

Researchers at UCLA have developed this organic solar cell, which promises a cheaper and more effective way to harness the sun’s power. The new cells could serve as a power-generating layer on windows and smartphones without obstructing a person’s ability to see through the surface.

Heartbeats under magnetic resonance imaging.
We seldom consider the force with which our hearts beat through every moment of our lives. Most of us will only ever feel the dampened strength of these muscles at the arteries of the wrist or neck, perhaps through a stethoscope or in moments of excitement, exertion and fear. Take a moment to consider it now, if you will.
