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
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.

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
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.

3D-printing perovskites on graphene makes next-gen X-ray detectors
By using 3D aerosol jet-printing to put perovskites on graphene, scientists at EPFL have made X-ray detectors with record sensitivity that can greatly improve the efficiency and reduce the cost and health hazard of medical imaging devices. Since Wilhelm Röntgen discovered them in 1895, X-rays have become a staple of medical imaging.

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.

Concept for a new storage medium
Physicists from Switzerland, Germany and Ukraine have proposed an innovative new data storage medium. The technique is based on specific properties of antiferromagnetic materials that had previously resisted experimental examination. Using nanoscale quantum sensors, an international research team has succeeded in exploring certain previously uncharted physical properties of an antiferromagnetic material.

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.

UC San Diego Physicists Uncover Phenomena Tied to New State of Matter
Take a window screen and put it on top of another. Slide the screens back and forth and a dizzying array of geometrical shapes and wavy patterns come into view. Known as the moiré effect, this phenomenon is now helping physicists at the University of California San Diego explain fundamental properties of exotic particles, such as excitons.

Swimming upstream on sound waves
Researchers are among the first scientists to have succeeded in propelling microvehicles against a fluid flow using ultrasound. In future, these tiny vehicles are set to be introduced into the human bloodstream, thereby revolutionising the field of medicine. At some point, microvehicles that are small enough to navigate our blood vessels will enable physicians to take biopsies, insert stents and deliver drugs with precision to sites that are difficult to reach, all from inside the body.

IBM's Quantum computer links two quantum revolutions
Using the IBM Q computer, physicists at EPFL have verified for the first time the tight relationship between quantum entanglement and wave-particle duality, showing that the former controls the latter in a quantum system. "It is possible to do experiments in fundamental physics on the remotely accessible IBM Q quantum computer ," says Marc-André Dupertuis, a physicist at EPFL's School of Basic Sciences.

Researchers Hunt for New Particles in Particle Collider Data
In physicists' ongoing search for new particles, it's always easiest to find them when you have an idea where to look. Theories can serve to narrow and focus those searches to particles with a particular mass or a mass range, or to those with specific parent, child, or sibling particles as they burst forth from the firework-like cascades of particle collisions.
