Coloured transmission electron micrograph (TEM) of chloroplasts from the yellow portion of a yellow/green variegated Coleus blumei plant. Chloroplasts are the sites of photosynthesis, the process that synthesises carbohydrates from carbon dioxide and water using sunlight. The structure of a variegated chloroplast is slightly different from that of a normal green chloroplast. The granal stacks, formed from parallel thylakoids (membranes, bright lines), that contain the chlorophyll pigments are less ordered in the variegated chloroplast. The pigments themselves are also slightly different. Magnification: x14,300 when printed at 10cm wide.

Quantum theory continues to challenge our conception of reality

IT IS one of those delicious ironies of history that Albert Einstein received the 1921 Nobel prize in physics not for general relativity , the theory of gravity for which he is now justly most famed, but largely for his contribution to a theory that he spent much of his later career trying to disown. …
