Stylus in LP record Featured October Image

Stylus in LP record

Stylus on LP record. Coloured scanning electron micrograph (SEM) of a stylus travelling through the grooves of a stereo vinyl record. The grooves are cut into a flat disc of polyvinyl chloride (PVC). The grooves vary with the intensity of the music: the straighter the groove the quieter the music, the wavier the groove the louder the music. Vibrations are picked up by the stylus and transduced by a moving-coil or moving-magnet cartridge into an electrical signal, which passes through an amplifier to be heard on loudspeakers.

Hazel pollen grains

Hazel pollen grains. Coloured scanning electron micrograph (SEM) of pollen grains from the Hazel tree, Corylus avellana. These microspores are shed from male catkins (hanging pollen-bearing structures) on the Hazel tree, released into the air and carried by wind to pollinate the female flowers. Pollen grain shape, size and surface sculpturing varies greatly between species, and may be used by botanists to identify plants from pollen grains. Large quantities of Hazel pollen occur as a fine yellow mist at springtime in parts of Europe, and may contribute to attacks of hay fever (allergic rhinitis). Magnification: x1, 730 at 5x7cm size
