’Tug of war’ between cells - When crucial connections are missing
Research team led by University of Göttingen investigates the importance of "tight junctions" for cell movement The ability of cells to move together in harmony is crucial for numerous biological processes in our body, for example wound healing, or the healthy development of an organism. This movement is made possible by the connections between individual cells.

Can we cope without rare-earth elements?
Researchers look for materials for the future A mobile phone is full of raw materials: its electronic components contain valuable precious metals, such as gold, silver and platinum, rare metals, like cobalt, gallium or indium, and rare-earth elements, such as neodymium. Often, the old devices end up in the bin - and, with them, their precious cargo.

How the Sun's magnetic forces arrange gas particles
How the Sun’s magnetic forces arrange gas particles
Research team including Göttingen University observes charged particles 70 percent faster than uncharged Solar prominences hover above the visible solar disk like giant clouds, held there by a supporting framework of magnetic forces, originating from layers deep within the Sun. The magnetic lines of force are moved by ever-present gas currents - and when the supporting framework moves, so does the prominence cloud.

Novel quantum effect discovered in naturally occurring graphene
Novel quantum effect discovered in naturally occurring graphene
International research team led by University of Göttingen finds atomically-thin carbon generates its own magnetic field Usually, the electrical resistance of a material depends very much on its physical dimensions and fundamental properties. Under special circumstances, however, this resistance can adopt a fixed value that is independent of the basic material properties and "quantised" (meaning that it changes in discrete steps rather than continuously).

Creating order by mechanical deformation in dense active matter
Creating order by mechanical deformation in dense active matter
Researchers at Göttingen University use computer simulation to investigate models of living systems Living or biological systems cannot be easily understood using the standard laws of physics, such as thermodynamics, as scientists would for gases, liquids or solids. Living systems are active, demonstrating fascinating properties such as adapting to their environment or repairing themselves.

Bacterial toxin blinds algae
Bacterial toxin blinds algae
Jena research team discovers natural product from soil bacteria that kills algae Life University of Jena researchers have discovered a bacterial toxin that destroys the colour pigments in the eyespot of the single-cell green alga Chlamydomonas reinhardtii. Together with another toxic substance, the bacteria of the species Pseudomonas protegens not only disorientate and immobilise the green algae, but condemn them to a certain death.

Qubits Under Pressure
Qubits Under Pressure
A new type of atomic sensor made of boron nitride is presented by researchers in "Nature Communications". The sensor is based on a qubit in the crystal lattice and is superior to comparable sensors. 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.
