Samuel Hahnemann, German physician

Samuel Hahnemann (1755-1843), German physician and founder of homeopathy. His theory was that an illness may be cured by administering minute doses of a drug which causes the same symptoms. The symptoms, he reasoned, were an effect of the body's fight against disease. During experiments on himself and his friends he found that the smaller the administered dose, the greater its effectiveness. In 1811, he published his results in Homeopathic Materia Medica. He used his methods with some success during a typhus epidemic in France in 1812. Although his results were criticised, homeopathy spread rapidly in the ensuing decades

False colour scanning EM, head of bulldog ant

False-colour scanning electron micrograph of the head of a bulldog ant. This is probably a Black bulldog ant, Myrmecia forficata, found in coastal Australia and Tasmania. Bulldog ants can be up to two centimetres long, and their powerful jaws (shown here in red) produce a very painful and unpleasant bite. They live in fairly small colonies of a few hundred in underground nests. The adults feed on the sweet juices of plants, but they hunt aggressively for insects and spiders to feed to their larvae in the nest. Magnification: x12 at 6x6cm size
