Foraminifera are single-celled organisms with internal calcerous shells, known as tests. The image above shows a shell with a planispiral chamber arrangement — during growth, chambers are added sequentially to form a coil in a flat spiral. Foraminiferan tests are quite diverse. The image shown here came from a study on the nature of the material in the calcerous test and how the foraminifera de...

Electric fields are pervasively present in the environment and occur both as a result of man-made activities and through natural occurrence. We have analysed the behaviour of cockroaches to static electric fields and determined the physiological mechanisms that underlie their behavioural responses. The behaviour of animals in response to electric fields was tested using a Y-choice chamber with ...

The AIDA (Aerosol Interactions and Dynamics in the Atmosphere) aerosol and cloud chamber of Forschungszentrum Karlsruhe can be used to test the ice forming ability of aerosols. The AIDA chamber is extensively instrumented including pressure, temperature and humidity sensors, and optical particle counters. Expansion cooling using mechanical pumps leads to ice supersaturation conditions and possi...
