In Pictures: The International Images for Science at the Hancock Newcastle

| 22 August 2013

In the first part of a series of images from the International Images for Science exhibition, we find weevils, wasps and jellyfish...

Bernardo Cesare, Sunflower of Jasper (2010)

This is a rhyolite volcanic rock that contains a large proportion of silicate minerals. As the rock cools, small aggregates of quartz or feldspar develop which act as seeds for these radial inclusions.

Ocean jasper is found only in Madagascar and is highly prized among collectors. Here, a thin section of rock just 30 micrometres thick has been polished and polarised light shone through it.

A second polarising filter reveals these amazing colours. Photographed using a Canon EOS 55D camera on a Zeiss microscope.

There are more than 40,000 species of true weevils in the family Circulionidae, beetle-like creatures typified by a long snout and clubbed antennae.

This is part of a series investigating our often-overlooked housemates, a result of the expansion of our habitat into rural areas.

The image is a composite of light microscopy and scanning electron microscopy.

Dan Sykes, A Blaschka Jellyfish (2013)

The artificial colours used here are based on the density of the glass.

This incredible model was sculpted in glass in the mid-19th Century by Leopold and Rudolf Blaschka.

The techniques used by this father and son team are not fully understood - it is hoped that a study will help reveal some of their secrets.

Daniel Kariko, Cuckoo Wasp Found on Window Screen (2013)

Cuckoo wasps belong in the family Chrysidae, with more than 3,000 known species.

Common names also include jewel wasp, gold wasp or emerald wasp, reflecting their brilliantly coloured, metal-like bodies.

Most species are cleptoparasites – laying their eggs in host nests where their larvae eat the host egg or larvae.

Steve Lowry, Leaf Hairs on Deutzia scabra (2012)

The deutzias are members of the hydrangea family and are commonly cultivated as an ornamental plant.

The leaves have these stellate hairs, each of which is about 0.4mm across. Up to 20 species of Deutzia can be differentiated by the density and size of the hairs and the number of points on the ‘stars’.

In Japan, traditional carpenters use leaves from D. scabra as a final polishing agent for mahogany.
