Sustainable chemistry based on wood

Some hikers carry a small solar power generator with them, a foil attached to their backpack that converts sunlight into electricity. This allows them to charge their devices while on the move. Flexible, thin and lightweight ...

Wild honeybees still exist in Europe

Until recently, experts considered it unlikely that the honeybee had survived as a wild animal in Europe. In a current study, biologists Benjamin Rutschmann and Patrick Kohl from Julius-Maximilians-Universität Würzburg ...

Triangular honeycombs: Physicists design novel quantum material

Smartphones, notebooks and other electronic devices of our everyday life strongly benefit from the ever-increasing miniaturization of semiconductor devices. This development comes however at a price: confining electrons enhances ...

Qubit in a crystal lattice of boron nitride is a suitable sensor

An artificially created spin defect (qubit) in a crystal lattice of boron nitride is suitable as a sensor enabling the measurement of different changes in its local environment. The qubit is a boron vacancy located in a two-dimensional ...

An atlas of the bumblebee brain

The buff-tailed bumblebee Bombus terrestris is one of the most common bumblebee species in Europe. It is not only active in nature as a pollinator—humans also use it in greenhouses and foil tunnels to get good harvests ...
