How mercury gets into the sea

Mercury released into the atmosphere by industry enters the sea and from there makes its way into the food chain. Now, an analysis by the University of Basel has revealed how the harmful substance enters seawater in the first ...

Highly dynamic sex chromosomes in cichlid fishes

The cichlids of Lake Tanganyika in Africa are highly diverse—including with regard to sex chromosomes. These have changed extremely frequently in the course of the evolution of these fish and, depending on the species, ...

Thinking in 3D improves mathematical skills

Spatial reasoning ability in small children reflects how well they will perform in mathematics later. Researchers from the University of Basel recently came to this conclusion, making the case for better cultivation of spatial ...

Stretching changes the electronic properties of graphene

The electronic properties of graphene can be specifically modified by stretching the material evenly, say researchers at the University of Basel. These results open the door to the development of new types of electronic components.

Unusual prey: Spiders eating snakes

There are spiders that eat snakes. Observations of snake-eating spiders have been reported around the world. Two researchers from Basel and the US consolidated and analyzed over 300 reports of this unusual predation strategy.

Excess nitrogen puts butterflies at risk

Nitrogen from agriculture, vehicle emissions and industry is endangering butterflies in Switzerland. The element is deposited in the soil via the air and has an impact on vegetation—to the detriment of the butterflies, ...

Quantum steering for more precise measurements

Quantum systems consisting of several particles can be used to measure magnetic or electric fields more precisely. A young physicist at the University of Basel has now proposed a new scheme for such measurements that uses ...
