Dahlia flower pollen, SEM

Dahlia flower pollen. Coloured scanning electron micrograph (SEM) of a pollen grain (orange) from a Dahlia cultorum flower. A pollen grain contains a male sex cell from a flowering plant. Millions of pollen grains are produced by a flower. Some of these pollen grains are transported from a flower's anthers to the female reproductive parts of a plant, in a process called pollination. This allows the female and male sex cells to combine in the formation of a seed. Dahlias are popular garden flowers

Light bulb from a car headlamp Featured 12 Jul 2005 Image

Light bulb from a car headlamp

Light bulb from a car headlamp. This is a tungsten-iodide bulb, designed to be more reliable and work at higher temperatures than normal light bulbs. In an ordinary light bulb tungsten in the heated filament gradually evaporates, blackening the bulb and causing the filament to thin until it snaps. In a tungsten-iodide bulb the atmosphere is iodine. This combines with evaporated tungsten atoms to form tungsten-iodide, a gas. When this gas is warmed by the filament this molecule decomposes into tungsten and iodine again, redepositing tungsten on the filament
