“Only the beginning of massive global digitalisation”

“What we are seeing is only the beginning of massive global digitalisation, but it is happening rapidly”, says Stefan Larsson, sociology of law researcher and director of the Lund University Internet Institute. “I believe we are going to see extensive development of methods in the social sciences and humanities that...

Balancing act in the air

All animals need some form of warning system that prevents them from colliding with objects in their surroundings. The warning system helps them to continually regulate their speed and determine their distance from objects. The Vision Group at the Department of Biology in Lund studies how insects control their progress...

The Elephant hawk moth, Deilephila elpenor. These moths not only have good night vision, they can also distinguish the colours of flowers by the light of the stars.

Razor-sharp eyesight in the night-time jungle

Some insects have exellent nocturnal vision, despite having the same type of compound eyes as insects that are active during the day. Nocturnal bees in the rainforests of Panama can percieve light intensities that are 100 million times weaker than daylight! HOW DO FLYING INSECTS IMPROVE THEIR EYESIGHT AT NIGHT?...

The tropical bee, Megalopta genialis, can perceive light intensities that are 100 million times weaker than daylight. This nocturnal bee is one of the insects that provided inspiration for a night vision video camera. Scanning electron microscope image by Rita Wallén.

Car’s video camera helps you see like an insect

The way that nocurnal insects intensify incoming light could be used to improve how cameras function in low light. Eric Warrent had the idea of applying his insect vision algorithm to a video camera. The algorithm senses how light it is and how much the camera is moving. Just as...

Big data and Big Brother – perhaps not only in China?

Who controls data that users create on social media? In China, the State keeps tabs on most things. In the US it is the private corporations – or is it the NSA? In Sweden and the EU, discussions are ongoing on how to regulate online data and protect users’ privacy....

Security important for storing health data

Security has been regarded as very important in EpiHealth, a research collaboration between Lund and Uppsala universities. The project’s register currently contains data about 18 000 people between the ages of 45 and 75 in Sweden. The aim is to study connections between genes, lifestyle and environmental factors and the most...

Beetle’s inspirational defence mechanism

Brachinus crepitans is a centimetre-long beetle that deters predators, such as ants and frogs, by turning its back to the attacker and loudly squirting it with a mist of irritating liquid. A few years ago, a research group at the University of Leeds had the idea of developing the beetle’s...

Nanowires could make cars more energy-efficient

Fuel consumption in cars could be reduced thanks to nanowires and a thermoelectric effect. This is what emerges from the basic research conducted by Sofia Fahlvik Svensson, a doctoral student at the Division for Solid State Physics in Lund University’s Faculty of Engineering. This autumn, she will be publicly defending...

Nano-forests to reveal secret of cells

Vertical nanowires could be used for detailed studies of what happens on the surface of cells. The findings are important for pharmaceuticals research, among other applications. A group of researchers from Lund University in Sweden have managed to make artificial cell membranes form across a large number of vertical nanowires,...
