The winning photos

1^st prize

Blue Seeding By Peter Morris This is a transgenic plant showing the expression pattern of a specific gene. The plant gene has been fused to a marker gene that produces an enzyme which will cleave a substrate to yield a blue dye.

		Made to measure stencil: HWU shines through By Aongus McCarthy Viewing transparent moulded plastic items between crossed polarisers can reveal colourful stress patterns because of the induced birefringence. The symmetry of the H-W-U letters in this plastic stencil meant that they looked the same, and were in the “right” order, when the stencil was turned over! The letters were made to appear bright between crossed polarisers by using pieces of sellotape which cause the plane of polarisation to be rotated.

		Clamp down on stress Aongus McCarthy Certain transparent materials reveal colourful contour patterns when they are placed under mechanical stress and viewed between crossed polarisers. The patterns are visible because of the induced birefringence which is proportional to the applied stress. This is known as mechanical birefringence or photo elasticity, and was first described by the Scottish physicist Sir David Brewster in the early 19th century.

Waves and Chaos in Oscillatory Systems Jonathan Sherratt and Matthew Smith Many natural populations undergo multi-year cycles, and field studies have shown hat these can be organized into periodic travelling waves. Mathematical studies have shown that large-scale landscape obstacles represent a natural mechanism for wave generation. This figure shows a numerical simulation of this process of wave generation for a caricature model of an oscillatory ecological system. In the left hand panel the obstacle is the small central circle, and it generates a stable wave pattern. But in the right hand panel the obstacle is larger, and this causes the generation of a wave that is of lower amplitude and is unstable. It is visible close to the obstacle but then breaks down into spatiotemporal chaos. In oscillatory systems, invasion generates a spatiotemporal transition through periodic cycles, leading ultimately to spatiotemporal chaos.
