Defects in quartz crystal structure reveal the origin of dust
Defects in quartz crystal structure reveal the origin of dust
Global warming and a progressively drier climate in many parts of the world are causing more dust storms. To predict how these storms are caused, researchers are looking into the past to understand where the dust came from, for how long, and over what distances it was transported. An international research team led by Dr. Aditi K. Dave and Professor Kathryn Fitzsimmons from the Department of Geosciences at the University of Tübingen, along with colleagues from Romania, Brazil, Kazakhstan and Tajikistan, have now developed a new method of doing this.

Long-sought tetra-neutron discovered
Long-sought tetra-neutron discovered
After 60 years of unsuccessful searches, an international research team has discovered a neutral nucleus for the first time - the tetra-neutron. The collaboration succeeded in creating an isolated four-neutron system with low relative kinetic energy in a volume equivalent to an atomic nucleus. The building blocks of atomic nuclei are the nucleons, which come in two types, the neutral neutrons and the positively charged protons - the two so-called isospin states of the nucleon.

Microscopy technique enables 3D super-resolution nanometre-scale imaging
Research team led by Göttingen University combine two techniques to achieve isotropic super -resolution imaging Over the last two decades, microscopy has seen unprecedented advances in speed and resolution. However, cellular structures are essentially three-dimensional, and conventional super-resolution techniques often lack the necessary resolution in all three directions to capture details at a nanometer scale.

A nose for damaged plants and fake perfumes
Researchers develop a highly sensitive novel technique capable of detecting chiral molecules within complex gas mixtures The chiral signature of a fragrance can reveal whether a perfume is genuine or fake. Similarly, the chiral signature of the emissions of a plant can provide information on whether the plant is healthy or sick.

Using quantum technology to ensure low-noise microphones
Use of quantum light leads to a significant improvement in signal-to-noise ratio [Picture: PI 3 / Florian Kaiser] Whether it's an online conference or a hearing aid, a high noise level in the microphones used, or significant background noise will disrupt any conversation, and better microphones are urgently needed.

New insights into binding configuration and mobility of molecules on nanoparticle surfaces
Freiburg physicists investigate binding between molecules and nanoparticles with high resolution How molecules bind to a surface is of central importance in chemical reactions, making the possibility of studying binding configurations in isolated nanosystems of great interest. A Freiburg research team led by Dr. Lukas Bruder and Frank Stienkemeier has now succeeded in studying the binding configurations and mobility of organic molecules on ultracold noble gas particles.

Quantum one-way street in topological insulator nanowires
Very thin wires made of a topological insulator could enable highly stable qubits, the building blocks of future quantum computers. Scientists see a new result in topological insulator devices as an important step towards realising the technology's potential / publication in 'Nature Nanotechnology' An international group of scientists have demonstrated that wires more than 100 times thinner than a human hair can act like a quantum one-way street for electrons when made of a peculiar material known as a topological insulator.

An image of the Milky Way’s black hole
Observation with the Event Horizon Telescope improves our understanding of the processes at the galactic centre It sits deep in the heart of the Milky Way, is 27,000 light years from Earth, and resembles a doughnut. This is how the black hole at the centre of our galaxy appears in the image obtained by researchers using the Event Horizon Telescope (EHT).

Physicists study optically induced quantum dynamics in single-photon emitters
For tomorrow's quantum technologies: hexagonal boron nitride under the magnifying glass / findings published in -Optica- Quantum technologies are a seminal field of research, especially in relation to their application in communication and computing. In particular, the so-called single-photon emitters - materials that emit single light quanta in quick sequence - are an important building block for such applications.

Atomic terahertz vibrations generate soliton molecules
Atomic terahertz vibrations generate soliton molecules
Stable packets of light waves - called optical solitons - are emitted in ultrashort-pulse lasers as a chain of light flashes. These solitons often combine into pairs with very short temporal separation. Introducing atomic vibrations in the terahertz range, researchers at the Universities of Bayreuth and Wroclaw have now solved the puzzle of how these temporal links are formed.

Their microdrones are significantly smaller than red blood cells. A hand-held laser pointer produces no noticeable recoil forces when it is "fired" - even though it emits a directed stream of light particles.

MAGIC telescopes observe stellar explosion
MAGIC telescopes observe stellar explosion
The MAGIC telescopes have observed the nova RS Ophiuchi shining brightly in gamma rays at extremely high energy. The Gamma rays emanate from protons that are accelerated to very high energies in the shock front following the explosion. This suggests that novae are also a source of the ubiquitous cosmic radiation in the universe which consists mainly of protons rich in energy, which race through space at almost the speed of light.
