Investigating gravity waves and infrasound in the ionosphere

Written by

The Earth’s ionosphere provides a crucial barrier between the lower atmosphere and outer space – yet relatively little is known about how the complex dynamics of this layer are influenced by low-frequency atmospheric waves, generated close to Earth’s surface. In his research, Dr Jaroslav Chum at the Institute of Atmospheric Physics in Prague uses advanced observation techniques to investigate the […]

Laser induced damage threshold testing

Written by

Today’s latest laser technologies can be used for a diverse array of applications. Currently, however, their use is being hindered by a lack of knowledge about certain power thresholds, above which lasers can damage valuable materials and components. Through their research, Dr Jan Vanda and colleagues at the HiLASE Centre, part of the Institute of Physics at the Czech Academy […]

Scientists join the dots between lady beetles in Iran

Written by

Lady beetles are toxic to predators and display a colourful warning – the perfect example of aposematism. After tasting a bitter lady beetle, predators learn the colours to avoid in future. As a result, lady beetles of certain colour patterns are less likely to be eaten. Copying successful lady beetles helps to avoid predation. Professor Oldřich Nedvěd from the University […]
