Forensic identification, conceptual image
Hand print DNA assay

La Villette Gas Power Station, artwork
La Villette Gas Power Station, Paris, France. Artwork showing condenser tubes on the exterior of the building. The tubes condense exhaust steam from the turbines into water, which can be re-used

Cape reef worm tubes
Cape reef worm (Gunnarea capensis) tubes. These encrusted tubes, found on sheltered rocks in tidal areas, are formed by this polychaete worm from bits of grit and sand

Bronchus and bronchioles, artwork
Bronchus and bronchioles. Artwork of the anatomical structure of the bronchi and their bronchioles, the main aspects of the respiratory system

Polythene crop tunnels in Gazipasa Turkey

Solar powered torch on white background

Aristolochia sempervirens
Evergreen Dutchmans pipe (Aristolochia sempervirens). Two flowers are at upper centre and a fruit is at centre. Photographed on the Mani peninsula, Greece

Bioreactor. Small-scale bioreactor used for studying bacteria. Bioreactors are devices that maintain a specific environment to allow organisms or their derivative substances to undergo chemical

Electrolysis of water. Close-up of the top of a Hoffman Voltameter used to decompose molecules of water. A power supply (not seen)

Blood centrifuge. A centrifuge is a machine that spins its contents around a central axis at very high speeds. The force created by the spinning separates groups of particles according to their

Strychnine drug molecule
Strychnine. Molecular model of strychnine, an alkaloid drug that is used medicinally in low doses but which is also used as a poison for rats and other vermin

Fructose molecule
Fructose, molecular model. This is the sweetest of the sugars. It is found in fruits and honey. Atoms are represented as rods and are colour-coded: carbon (green), hydrogen (white) and oxygen (red)

Quinine malaria drug molecule
Quinine malaria drug, molecular model. Quinine is obtained from the bark of the cinchona tree (Cinchona sp.), which is native to South America. It has been used to treat malaria for over 300 years

Dyers greenweed stem, light micrograph
Dyers greenweed stem. Polarised light micrograph of a transverse section through the stem of a dyers greenweed (Genista tinctoria) plant

Elder tree stem, light micrograph
Elder tree stem. Light micrograph of a transverse section through the very young woody stem of an elder (Sambuca nigra) tree

Air compressor tubes. These tubes (yellow) are part of an air compressor, a machine used to compress air, usually to produce cylinders of pressurized gas or to provide pressure for a pneumatic

Mosquito pupa, SEM
Mosquito pupa, coloured scanning electron micrograph (SEM). This is a pupa from a Culex mosquito. The pupa is less dense than water and floats at the surface

Histidine amino acid
Histidine. Computer model of a molecule of the amino acid histidine (C6. H9. N3.O2). Atoms (solid tubes) are colour-coded: carbon (green), oxygen (red), hydrogen (grey) and nitrogen (blue)

Chlordane pesticide molecule
Chlordane pesticide, molecular model. Chlordane was used as an agricultural pesticide and an ant killer between 1948 and 1988, when it was banned due to its health effects

Capped nanotube, molecular model
Capped carbon nanotube, molecular model. It is called capped because the ends of the tubes have been rounded off to form an enclosed structure

Nanotube drug delivery, artwork
Nanotube drug delivery. Computer artwork showing antioxidant molecules BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) moving along the inside of a nanotube

Synthetic peptide fibre, molecular model
Synthetic peptide fibre. Molecular model of a synthetic collagen-like peptide fibre, showing three different ways of representing the structure. Peptides are small molecules formed from amino acids
