Human embryonic stem cell (gold) growing on a layer of supporting cells (fibroblasts). Stem cells are derived from very early embryos and can either be grown to stay in their original state or triggered to form almost any type of human cell. The fibroblasts provide special factors that maintain the stem cells in their original state. The stem cell appears to be grasped by the underlying fibroblast. Stem cell research could lead to cures for many diseases such as Parkinson's disease, Alzheimer's and diabetes, where a patient's cells are damaged or absent.

Myrtus communis L. Myrtaceae Myrtle Distribution: Europe. Dioscorides (Beck, 2005) recommends the fruit for treating haemoptysis (‘spitting blood’) and cystitis, and, if boiled, he said it made a fine wine. In various forms it was used as a hair dye, for sore eyes, anal and uterine prolapse, dandruff and shingles, all sorts of inflammations, scorpion bites and even sweaty armpits. Our plant has white berries, but he regarded those with black berries (they become black later in the season) as being more effective. Lyte (1576) adds that the juice of the berries kept the hair black and stopped it falling out, and prevented intoxication. He notes that it only flowered in hot summers in England, but it is reliable in flower now, either due to global warming or selection of suitable clones. According to Lyte, it is named after Merlyne, a fair maiden of Athens in ancient Greece, who judged the athletic games. Slain by a disgruntled competitor, the goddess Minerva brought her back as the myrtle tree in perpetual memory. The myrtle tree is also an ancient Jewish symbol for peace and justice. Myrtle wine is still made in Tuscany and now even in China. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
