Puffballs are the fruiting bodies of soil-dwelling fungi. They contain the spores that

will develop into new puffballs. The release of

spores happens very quickly, but high-speed photography

can reveal it in detail

The surface tension of water can support even a metal paperclip. By photographing it using a grill in front of the light source, the deformation of the water caused

by the clip's weight can be seen. This bending of light is similar to the bending of light by strong gravitational

fields, as predicted by Einstein's theories. Surface tension is due to an attraction between the molecules in

water, which cause its surface to act in an elastic manner

The hairs on a tarantula don't just make it look scary; they are valuable weapons as well. When threatened,

the tarantula can flick these hairs off with its legs, firing them at would-be attackers. The spiky, branching hairs are extremely irritating to the eyes, skin and mucous membranes. This deters all but the most determined

assailant, allowing the spider to make its escape

Blue ink diffusing into water takes on the appearance of jubilant figures with raised

arms, as if in prayer

This image of a whole peppercorn with a grain of sea salt offers a close-up glimpse of the

structure of simple everyday products we use on our food.

The orientation of molecules within a liquid crystal can be seen by viewing the crystals using polarised light. Regions that have the

same colour here have the same orientation of their constituent

molecules

These are not orange starfish on a rocky seabed, but tiny star-shaped hairs on the underside of a plant’s

leaf. These projections, called trichomes, have a protective function. They can help to stop

insects from feeding on the leaf and also prevent excessive water loss

The back wall of this eyeball has been severely distorted by a large haemorrhaged region covering

much of the light-sensitive retina. This led to temporary blindness in this eye. The retina has

detached from the back of the eye and the resulting space has half filled with blood. The optic disc, where the optic nerve joins the eyeball, is the yellow area at

upper left.

This tiny shrimp fearlessly enters the mouth of a fish to clean its teeth. Fish value this service as the shrimp removes and eats harmful parasites. The

shrimp lives in the sea anemone in the background. Fish recognize the anemone as a cleaning station, and

when they need a clean they approach it and open their mouths, encouraging the shrimp in. This is

mutualism - a form ofsymbiosis in which both partners benefit

This highly magnified image reveals the dynamic life of cells in culture as they extend growth cones to move around, interact with other cells and investigate their environment. Here three main parts of the cells can be seen: their nuclei (blue) containing the cell's DNA, the

structural protein tubulin (green) which is like an escalator moving things around inside the cell and actin (red), acontractile protein that helps the cells to move

around

These synthesized nanowires, grown on grids, have developed into 3D nanoflowers. Whilst pleasing to look at, the aim of researching synthesised nano-materials is

that tiny wires like this could one day be used in the smallest computers and cell-sized machines. Each wire here is about a fifth of a micron wide, some 400 times

thinner than a human hair .

We’ve all heard a

balloon pop, but it

happens too fast for us

to see in detail. High-

speed photography

shows what is happening

at the time of the pop,

the stretched skin of the

balloon rupturing rapidly

and violently.
