Cancerous tumor tissue under a microscope: T cells grown under low oxygen conditions (green) and regular T cells (purple) show similar distribution patterns vis-à-vis blood vessels (red). Right: The content of granzyme B, a cell-killing enzyme (red), is much higher in T cells grown under low oxygen conditions (top) than in regular T cells (bottom).

Emmanuel Levy - Department of Structural Biology

Yeast cells producing a bacterial symmetric protein complex with eight units. When it is not mutated (left), the complex diffuses freely inside the cell, but a single mutation (right) triggers its assembly into long filaments 

Emmanuel Levy - Department of Structural Biology

Electron microscopy of the filaments reveal Lego-like stacking of protein complexes.

Unripe (top) and ripe (bottom) tomatoes. Regular tomatoes (far left) start out green and turn red when ripe. In contrast, genetically engineered tomatoes assume different shades of red-violet, depending on whether they produce betalains (second from left), pigments called anthocyanins (second from right) or betalains together with anthocyanins (far right)

Asaph Aharoni - Department of Plant and Environmental Sciences

Tobacco flowers in nature are pale pink (far left), but can take on new colors (three images on the right) when genetically engineered to produce betalains
