Children under a sunlamp, 1960

Phototherapy. Children sitting under a sun lamp. Such lamps have a very bright, broad spectrum output. At the longer wavelength end of the spectrum (red and infrared) this gives a sensation of warmth on the skin while the higher wavelengths (blue and ultraviolet) promote the production of Vitamin D. In many northern European countries such therapies used to be given during winter periods, ostensibly to make the children 'healthy'. Photographed in Russia in 1960

Aesculus hippocastanum flowers blushing Featured 24 Jan 2014 Print

Aesculus hippocastanum flowers blushing

Flowers of the horsechestnut, Aesculus hippocastanum, a native of the Balkans, and an exotic in the UK. Flowers are borne in large panicles in Spring. Initially, each flower is white with a yellow blotch in the centre. As the flower ages, this changes in hue through orange to a bright red. This is thought to be a result of the fertilisation of the flowers at some time after opening. Many flowers change colour as they age, which may be a signal to passing bees that they have already been pollinated and stripped of nectar by previous visitors. In the case of the horsechestnut, the change from yellow to red is appropriately known as blushing". The pictures shows a panicle which began flowering a week previously. In each cluster of flowers, the lowest is the most recently opened, and yellow tinted. Older flowers are orange or red."

Alfred Russel Wallace, British naturalist

Alfred Russel Wallace (1823-1913), British naturalist, in middle age. Wallace organised expeditions to the Amazon and Malaysia and was the first European to see orang-utans in the wild. Wallace collected many specimens and founded the study of the geographical distribution of animals (biogeography). He formulated (independently of Charles Darwin) the theory of natural selection as a mechanism for the origin of species. He and Darwin presented their results in a joint paper in 1858 before the Linnean Society of London. Photographed by Florence Chant, based in Parkstone, Dorset
