This sealing is achieved through structures called tight junctions. However, how these tight junctions form has long been a mystery. Now, biologists have uncovered that the proteins responsible for these seals form a liquid-like material on the cell surface much like the water that condenses on a cold window.

Seeing the future: Zebrafish regenerates fully functional photoreceptor cells and restores its vision

Blinding diseases lead to permanent vision loss by damaging photoreceptor cells, which humans cannot naturally regenerate.
