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.

'Hot' graphene reveals migration of carbon atoms
’Hot’ graphene reveals migration of carbon atoms
The migration of carbon atoms on the surface of the nanomaterial graphene was recently measured for the first time. Although the atoms move too swiftly to be directly observed with an electron microscope, their effect on the stability of the material can now be determined indirectly while the material is heated on a microscopic hot plate.

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.

Quantum network nodes with warm atoms
Quantum network nodes with warm atoms
Communication networks need nodes at which information is processed or rerouted. Physicists at the University of Basel have now developed a network node for quantum communication networks that can store single photons in a vapor cell and pass them on later. In quantum communication networks, information is transmitted by single particles of light (photons).

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.

Track-and-trace method predicts best possible resolution in microscopy
TU Delft scientists provide insight into the limitations of super-resolution microscopy and offer a new calculation method to determine maximum resolution. The major precision improvements previously made by fellow-researchers is nuanced by their publication. The technology is important for studying processes in the living cell, discovering the origin of diseases and developing new medicines.

Boosting light power revolutionizes communications and autopilot
Boosting light power revolutionizes communications and autopilot
Scientists have built a compact waveguide amplifier by successfully incorporating rare-earth ions into integrated photonic circuits. The device produces record output power compared to commercial fiber amplifiers, a first in the development of integrated photonics over the last decades. Erbium-doped fiber amplifiers (EDFAs) are devices that can provide gain to the optical signal power in optical fibers, often used in long-distance communication fiber optic cables and fiber-based lasers.

How wet chopsticks hitting hot oil advance our understanding of physics
How wet chopsticks hitting hot oil advance our understanding of physics
Researchers find the physics of frying food far more complex than anticipated By Cooks throughout Asia put moist bamboo chopsticks into oil in a frying pan, watching the bubbles that form and listening to the sizzling sound they make as they burst to gauge the perfect cooking temperature. An international team of researchers used the technique as inspiration to learn about the complex physics behind wet chopsticks hitting hot oil.

Nanoparticles control light like road signs direct traffic
Physicists at The Australian National University (ANU) have developed tiny translucent slides capable of producing two very different images  depending on the direction in which light travels through them. As light passes through the slide, an image of Australia can be seen, but when you flip the slide and look again, an image of the Sydney Opera House is visible.

Mechanotransduction: nuclear mechanics to understand health and diseases
Mechanotransduction: nuclear mechanics to understand health and diseases
The application of mechanic forces to the cell nucleus affects the transport of proteins through the nuclear membrane, an action that controls cellular processes and could play a key role in several diseases such as cancer. These findings draw a new scenario for understanding how the mechanic forces drive the progression of the cancer and open the doors to the design of potential innovative techniques —both diagnostic and therapeutical.

Astronomers may have detected a 'dark' free-floating black hole
Astronomers may have detected a ’dark’ free-floating black hole
If, as astronomers believe, the death of large stars leave behind black holes, there should be hundreds of millions of them scattered throughout the Milky Way galaxy. The problem is, isolated black holes are invisible. Now, a team led by University of California, Berkeley, astronomers has for the first time discovered what may be a free-floating black hole by observing the brightening of a more distant star as its light was distorted by the object's strong gravitational field - so-called gravitational microlensing.

Eternal matter waves
Eternal matter waves
Amsterdam physicists build an atom laser that can stay on forever Imagining our everyday life without lasers is difficult. We use lasers in printers, CD players, pointers, measuring devices, and so on. What makes lasers so special is that they use coherent waves of light: all the light inside a laser vibrates completely in sync.
