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
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
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
Jena research team discovers natural product from soil bacteria that kills algae 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
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.

Spin-sonics: Acoustic wave gets the electrons spinning: Team of researchers first to demonstrate spin of a nano-sonic wave
A team of German and American researchers from Augsburg, Münster, Edmonton, West Lafayette and Munich have detected the rolling movement of a nano-acoustic wave predicted by the famous physicist and Nobel prize-winner Lord Rayleigh in 1885. In a study published in the journal "Science Advances", the researchers use a nanowire inside which electrons are forced onto circular paths by the spin of the acoustic wave.

Silicon with a Two-Dimensional Structure
Heidelberg chemists succeed in producing synthesis and complete characterisation for the first time Silicon, a semi-metal, bonds in its natural form with four other elements and its three-dimensional structure takes the form of a tetrahedron. For a long time, it seemed impossible to achieve the synthesis and characterisation of a two-dimensional equivalent - geometrically speaking, a square.

Simplified method for calibrating optical tweezers: Broadband measurement of viscoelasticity with reduced measurement time
Measurements of biomechanical properties inside living cells require minimally invasive methods. Optical tweezers are particularly attractive as a tool. It uses the momentum of light to trap and manipulate microor nanoscale particles. A team of researchers led by Cornelia Denz from the University of Münster has now developed a simplified method to perform the necessary calibration of the optical tweezers in the system under investigation.

The virus trap
Hollow nano-objects made of DNA could trap viruses and render them harmless To date, there are no effective antidotes against most virus infections. An interdisciplinary research team at the Technical University of Munich (TUM) has now developed a new approach: they engulf and neutralize viruses with nano-capsules tailored from genetic material using the DNA origami method.

Zeitabhängige Berechnung eines Bose-Einstein-Kondensats
The term Bose-Einstein condensate describes a state of matter in which atoms or elementary particles combine into a single quantum mechanical object during extreme cooling. Science does not yet fully understand exactly how these macroscopic states - beyond the confines of traditional physics - develop from a thermal atomic cloud in just a few milliseconds and when statistical equilibrium is reached, according to Georg Wolschin.

Multitalented filaments in living cells
Göttingen researchers investigate special properties of protein structures   The cells that make up our bodies are constantly exposed to a wide variety of mechanical stresses. For example, the heart and lungs have to withstand lifelong expansion and contraction, our skin has to be as resistant to tearing as possible whilst retaining its elasticity, and immune cells are very squashy so that they can move through the body.

Tailored laser fields reveal properties of transparent crystals
Research team led by the University of Göttingen investigates surface magnetisation The surface of a material often has properties that are very different from the properties within the material. For example, a non-conducting crystal, which actually exhibits no magnetism, can show magnetisation restricted to its surface because of the way the atoms are arranged there.
