How ultracold, superdense atoms become invisible
An atom's electrons are arranged in energy shells. Like concertgoers in an arena, each electron occupies a single chair and cannot drop to a lower tier if all its chairs are occupied. This fundamental property of atomic physics is known as the Pauli.....»»
Astronomers discover new link between dark matter and clumpiness of the universe
In a study published today in the Journal of Cosmology and Astroparticle Physics, researchers at the University of Toronto reveal a theoretical breakthrough that may explain both the nature of invisible dark matter and the large-scale structure of th.....»»
Single-atom vacancies in atomically thin insulators created in ultra-high vacuum
Single photons have applications in quantum computation, information networks, and sensors, and these can be emitted by defects in the atomically thin insulator hexagonal boron nitride (hBN). Missing nitrogen atoms have been suggested to be the atomi.....»»
Unveiling the invisible: A breakthrough in spectroscopy to allow discoveries in materials physics
Scientists from the University of Ottawa and the Max Planck Institute for the Science of Light are proposing a breakthrough approach that will facilitate discoveries in materials science by combining terahertz (THz) spectroscopy and real-time monitor.....»»
Why Sony wants to sell you invisible technology
Sony and Stellar Works envision a more design-focused future for the smart home. In 2018, Sony proposed a world with invisible technology. The Hidden Senses exhibition, which was held during Milan Design Week that year, included a candle holder that.....»»
Billion-year-old grease hints at long history of complex cells
Our ancestors once thrived on cholesterols that are now just reaction intermediates. Enlarge / All steroids past and present share the complex ringed structure but differ in terms of the atoms attached to those rings. (credit: KA.....»»
Research sheds light on new model of cosmological dark matter
Newcastle University researchers used insights gained from the study of ultracold atomic Bose Einstein condensates to analyze the behavior of fuzzy dark matter, a new model for cosmological dark matter that has recently drawn the attention of cosmolo.....»»
Precision nuclear physics in Indium-115 beta decay spectrum using cryogenic detectors
Certain isotopes such as Indium-115 (In-115) are extremely long lived, taking over 100 trillion years for half of the Indium atoms to decay away. These isotopes allow scientists to probe the precise internal processes that govern other extremely long.....»»
Flat fullerene fragments attractive to electrons, shows study
Researchers at Kyoto University in Japan have gained new insights into the unique chemical properties of spherical molecules composed entirely of carbon atoms, called fullerenes. They did it by making flat fragments of the molecules, which surprising.....»»
Symmetry breaking by ultrashort light pulses opens new quantum pathways for coherent phonons
Atoms in a crystal form a regular lattice, in which they can move over small distances from their equilibrium positions. Such phonon excitations are represented by quantum states. A superposition of phonon states defines a so-called phonon wavepacket.....»»
Study proposes achromatic metalens with varifocal performance
Metalenses, comprising one of the most prominent applications of metasurfaces, demonstrate promising abilities to replace traditional lenses. By manipulating the phase distribution of metalenses composed of appropriately arranged meta-atoms, the wave.....»»
Beneficial "bioaeorosols" are in the air we breathe—and they"re fast disappearing
With air pollution and airborne contaminants emerging as leading causes of illness and death, ecologists are calling for closer examination of the 'invisible friends' which live in the 15,000 liters of air we breathe every day......»»
Forget Fully-Electric Planes; Hydrogen Tech Is Closer Than You Think
Hydrogen is the most abundant element, accounting for 9 out of 10 atoms in the entire universe, making it a good potential fuel source. Hydrogen is the most abundant.....»»
Uncovering universal physics in the dynamics of a quantum system
New experiments using one-dimensional gases of ultra-cold atoms reveal a universality in how quantum systems composed of many particles change over time following a large influx of energy that throws the system out of equilibrium. A team of physicist.....»»
The "invisible" cellulose coatings that mitigate surface transmission of pathogens
Research has shown that a thin cellulose film can inactivate the SARS-CoV-2 virus within minutes, inhibit the growth of bacteria including E. coli, and mitigate contact transfer of pathogens......»»

Privoro collaborates with Samsung to protect customers from spyware attacks
Privoro announced a new partnership with Samsung to provide a security capability for mobile devices. The new capability provides a critical shield against the invisible threat posed by modern cyberweapons via high-assurance control over the radios,.....»»
Chemists find that metal atoms play key role in fine organic synthesis
A small team of chemists at the Russian Academy of Sciences, has found that metal atoms, not nanoparticles, play the key role in catalysts used in fine organic synthesis. In the study, reported in the Journal of the American Chemical Society, the gro.....»»
Advancing neutron diffraction for accurate structural measurement of light elements at megabar pressures
For decades, scientists sought a way to apply the outstanding analytical capabilities of neutrons to materials under pressures approaching those surrounding the Earth's core. These extreme pressures can rearrange a material's atoms, potentially resul.....»»
Scientists find link between photosynthesis and "fifth state of matter"
Inside a lab, scientists marvel at a strange state that forms when they cool down atoms to nearly absolute zero. Outside their window, trees gather sunlight and turn them into new leaves. The two seem unrelated—but a new study from the University o.....»»
Differing device personalities come together for future quantum computing networks
We're building the tools to trap ions and watch them glow (or not). The art-deco-esque device shown above is a combined trap for ions (charged atoms) and detector for individual photons (particles of light). When you hold an ion in place and hit it w.....»»
