Some raw materials are limited and not available and extractable everywhere in the world—as we are becoming acutely aware of right now by the example of fossil fuels and rising energy prices. Renewable raw material sources ...

Honeybees are less likely to sting in larger groups

To sting or not to sting? An alarm pheromone plays a decisive role in bees' willingness to sting—and their group size, as scientists from the University of Konstanz have now shown

A simple recipe for MRI contrasts up to four times higher

Are animal migrations social?

Migratory animals include a wide range of species—from tiny insects to the world's largest marine mammals. To achieve their journeys, migrants must walk, swim, or fly, often traversing complex landscapes that requires many ...

Team uses hot water to form photocatalyst

The production of chemical substances normally requires environmentally harmful solvents. After the research group of Miriam Unterlass, professor of solid state chemistry at the University of Konstanz, produced organic substances ...

Moving furniture in the micro-world

When moving furniture, heavy objects are easier to move if you rotate them while pushing. Many people intuitively do this. An international research team from Konstanz (Germany), Trieste and Milan (Italy) has now investigated ...

How glyphosate affects brood care in bumblebees

Bumblebee colonies exposed to glyphosate are significantly affected in times of resource scarcity. Dr. Anja Weidenmüller, biologist at the Centre for the Advanced Study of Collective Behavior at the University of Konstanz, ...
