Ocean currents off the Americas

Ocean currents off the Americas. Satellite-based graphic showing ocean currents (swirling coloured lines) on an Earth globe centred on the Americas. The colours indicate ocean temperatures, ranging from the warm tropics (red) to cooler water (green) in more temperate latitudes. Ocean currents seen here include the warmer Equatorial Counter in the Pacific (centre left), and the Gulf Stream in the Atlantic (upper right). The dusk terminator (day-night line) is at lower right, marking the places from where the Sun is seen setting in the west as the Earth rotates on its axis

EDTA crystals, light micrograph

EDTA crystals. Polarised light micrograph of a section through ethylenediaminetetraacetic acid (EDTA) crystals. EDTA is used primarily for its effectiveness at binding metal ions (chelating). After being bound by EDTA, metal ions remain in solution but exhibit distinctly diminished reactivity. In industry it has a variety of uses, including for dissolving limescale and preventing metal ion impurities from modifying the colours of dyed products. In medicine EDTA is used to treat heavy metal poisoning through chelation therapy, where it is used to bind metal ions in the body. Magnification: x100, when printed 10 centimetres wide
