SEM of ladybird over a flower
Ladybird in flight. Coloured scanning electron micrograph (SEM) of a seven-spot ladybird beetle Coccinella septempunctata, flying over a flower. The outer wings of the ladybird are strengthened into a hard covering called the elytra (red, black spots) to protect the delicate flight wings (long, white) found beneath. These elytra are raised in flight, while other transparent hind-wings (not seen) propel the insect. Seven black spots are found on the red wing covers of this ladybird. The red and black colours are a warning to predators, because this beetle is able to squirt distasteful fluids. Magnification: x2.9 at 6x7cm size. Magnification: x7.5 at 7x6 inch size.

DNA in all living things, artwork
DNA in all living things. Conceptual artwork representing the universality of DNA (deoxyribonucleic acid) and the genetic code in all living things. The strands of the DNA double helix make up a man's face. The helix contains yeast (a fungus, top), a flowering plant (upper right), a sheep (upper centre), a fruit fly (centre left), a pig (lower right) and a flatworm (bottom). Many of these organisms have been used in genetic research: sheep have been cloned, pigs have been genetically modified so that their organs can be transplanted into humans, fruit flies are used to study the effects of genes and yeasts have been used to produce human DNA for the Human Genome Project.

Common myna Acridotheres tristis
Common myna (or Indian Myna Acridotheres tristis). This bird is native to southern Asia from Afghanistan to Sri Lanka. The Myna has been introduced in many other parts of the world and its distribution range is on the increase to an extent that in 2000 the Species Survival Commission (IUCN) declared it among the Worlds 100 worst invasive species. and one of only three birds in this list. It is a serious threat to the ecosystems where introduced. Photographed in Israel in December
