Nanoscale sound waves vibrate artificial atom
A German-polish research team from Augsburg, Münster, Munich and WrocÅ‚aw successfully mixed nanoscale sound waves and light quanta. In their study published in Optica the scientists use an 'artificial atom' that converts the vibrations of the sound wave to single light quanta - photons - with unprecedented precision.

New insights into the mechanism of nuclear fission
Nuclear physicists at the University of Cologne have contributed to an international research collaboration to show the way the spin of the two fragments, resulting from the splitting of an atomic nucleus, is generated / publication in Nature A series of experiments at the ALTO particle accelerator facility in Orsay, France, has revealed that the fragments resulting from nuclear fission obtain their intrinsic angular momentum (or spin) after fission, not before, as is widely assumed.

Light-twisting 'chiral' nanotechnology could accelerate drug screening
Light-twisting ’chiral’ nanotechnology could accelerate drug screening
In a new drug screening technique that relies on gold nanorods to twist light, a red glow can signal the failure of a medication being designed to treat "amyloid” diseases such as Type II diabetes and pancreatic cancer. The technique was developed by researchers from the University of Michigan, Jilin University in China and the Federal University of São Carlos in Brazil.

For first time, researchers send entangled qubit states through a communication channel
In a breakthrough for quantum computing, University of Chicago researchers have sent entangled qubit states through a communication cable linking one quantum network node to a second node. The researchers, based in the Pritzker School of Molecular Engineering at the University of Chicago, also amplified an entangled state via the same cable first by using the cable to entangle two qubits in each of two nodes, then entangling these qubits further with other qubits in the nodes.

Identification of 'violent' processes that cause wheezing could lead to better diagnosis and treatment for lung disease
Identification of ’violent’ processes that cause wheezing could lead to better diagnosis and treatment for lung disease
A team of engineers has identified the 'violent' physical processes at work inside the lungs which cause wheezing, a condition that affects up to a quarter of the world's population. Since wheezing is associated with so many conditions, it is difficult to be sure of what is wrong with a patient just based on the wheeze Anurag Agarwal The researchers, from the University of Cambridge, used modelling and high-speed video techniques to show what causes wheezing and how to predict it.

Video of ’dancing DNA’ developed by researchers
Videos showing for the first time how small circles of DNA adopt dance-like movements have been developed by a team led by researchers at UCL and the Universities of Leeds, York and Sheffield. The footage is based on some of the highest resolution images of a single molecule of DNA ever captured, with DNA seen to "dance" in microscopy data recorded at the London Centre for Nanotechnology at UCL.  The images show in unprecedented detail how the stresses and strains that are placed on DNA when it is crammed inside cells can change its shape.

UChicago, Argonne scientists zero in on molecules that could fight COVID-19
A unique partnership among biologists, chemists and X-ray scientists at the University of Chicago and Argonne National Laboratory has zeroed in on several molecules that could be used to create drugs to fight COVID-19. Their results, published in  Nature Communications ,  help scientists understand the shape and structure of the virus and how it works-and how it can be blocked.

New Insight into Nonlinear Optical Resonators Unlocks Door to Numerous Potential Applications
Optical resonators, which circulate and confine light (for instance in lasers), are currently used in a variety of applications of all sizes-from pinpoint light sources smaller than the width of a human hair to kilometer-scale sensing devices such as the Laser Interferometer Gravitational-wave Observatory (LIGO) experiment that detects gravitational waves.

Unexpected antimatter asymmetry in the proton
Unexpected antimatter asymmetry in the proton
Symmetry is an important underlying structure of nature, present not only in mathematics and art, but also in living organisms and galaxies. Scientists originally thought protons, the positively charged particle at the center of every atom, displayed symmetry. But a research team that includes University of Michigan physicists has found the proton displays asymmetry in its makeup.

Ingredients for earliest life forms preserved in 3.5 billion-year-old rocks
Researchers including Göttingen University discover biologically-relevant organic molecules in fluid inclusions It is generally accepted that the earliest life forms used small organic molecules as building materials and energy sources. However, the existence of such components in early habitats on Earth had not been proven to date.

New Material is Next Step Toward Stable High-voltage Long-life Solid-state Sodium-ion Batteries
A team of researchers designed and manufactured a new sodium-ion conductor for solid-state sodium-ion batteries that is stable when incorporated into higher-voltage oxide cathodes. This new solid electrolyte could dramatically improve the efficiency and lifespan of this class of batteries. A proof of concept battery built with the new material lasted over 1000 cycles while retaining 89.3% of its capacity-a performance unmatched by other solid-state sodium batteries to date.

Twin atoms: A source for entangled particles
Quantum experiments that could previously only be performed with photons are now also possible with atoms: Beams of entangled atoms have been produced at TU Wien (Vienna). Heads or tails? If we toss two coins into the air, the result of one coin toss has nothing to do with the result of the other. Coins are independent objects.

Magnetic effect without a magnet
Surprise in solid-state physics: The Hall effect, which normally requires magnetic fields, can also be generated in a completely different way - with extreme strength. Electric current is deflected by a magnetic field - in conducting materials this leads to the so-called Hall effect. This effect is often used to measure magnetic fields.

Martian moons have a common ancestor
Phobos and Deimos are the remains of a larger Martian moon that was disrupted between 1 and 2.7 billion years ago, say researchers from the Institute of Geophysics at ETH Zurich and the Physics Institute at the University of Zurich. They reached this conclusion using computer simulations and seismic recordings from the InSight Mars mission.
