The formation of gap solitons in a 1D dissipative topological lattice
Topological photonics is a rapidly evolving area of research that focuses on the design of photonic lattices where the behavior of light is inspired from the physics of topological insulators. While most studies in this area presented photonic system.....»»
Astronomers analyze masses, orbital properties and atmospheric features of six exoplanets
A recently discovered solar system with six confirmed exoplanets and a possible seventh is boosting astronomers' knowledge of planet formation and evolution. Relying on a globe-spanning arsenal of observatories and instruments, a team led by research.....»»
Hubble views NGC 3384, a galaxy settling into old age
NGC 3384, visible in this image, has many of the characteristic features of so-called elliptical galaxies. Such galaxies glow diffusely, are rounded in shape, display few visible features, and rarely show signs of recent star formation. Instead, they.....»»
Discovery of high order skyrmions and antiskyrmions
Researchers at the University of Augsburg and the University of Vienna have discovered co-existing magnetic skyrmions and antiskyrmions of arbitrary topological charge at room temperature in magnetic Co/Ni multilayer thin films. Their findings have b.....»»
Webb sees dozens of young quasars in the first billion years of the universe
Within almost every galaxy is a supermassive black hole. Millions, sometimes billions of solar masses are locked within an event horizon of space and time. They can power luminous quasars, drive star formation, and change the evolution of a galaxy. B.....»»
Team expands research of water droplet interfaces that offer the secret ingredient for building life
R. Graham Cooks, the Henry B. Hass Distinguished Professor of Chemistry, and his postdoctoral researcher Lingqi Qiu have experimental evidence that the key step in protein formation can occur in droplets of pure water, and have recently published the.....»»
Hubble observes an askew galaxy coaxing star formation from its partner
Arp 300 consists of two interacting galaxies, UGC 05028 (the smaller face-on spiral galaxy) and UGC 05029 (the larger face-on spiral). Likely due to its gravitational dance with its larger partner, UGC 05028 has an asymmetric, irregular structure, wh.....»»
Research reveals quantum topological potential in material
New research into topological phases of matter may spur advances in innovative quantum devices. As described in a new paper published in the journal Nature Communications, a research team including Los Alamos National Laboratory scientists used a nov.....»»
Mars Express finds evidence of large water deposit at the Medusae Fossae Formation
Windswept piles of dust, or layers of ice? ESA's Mars Express has revisited one of Mars's most mysterious features to clarify its composition. Its findings suggest layers of water ice stretching several kilometers below ground—the most water ever f.....»»
Quantum physicists develop robust and ultra-sensitive topological quantum device
A significant breakthrough has been achieved by quantum physicists from Dresden and Würzburg. They've created a semiconductor device where exceptional robustness and sensitivity are ensured by a quantum phenomenon. This topological skin effect shiel.....»»
Research reveals gas-phase migration route for formation of strong metal-support interaction state
Strong metal-support interaction (SMSI) is one of the most important concepts in heterogeneous catalysis. Triggered by pretreatment or reaction processes, the supported metal nanoparticles may be partially or completely encapsulated by support-derive.....»»
New technique uses optical orbital angular momentum lattice to enhance information storage capacity
In the realm of optical holography, the conventional limitations of polarization, wavelength, and incident angle are giving way to a new era of possibilities. A breakthrough technique known as optical orbital angular momentum (OAM) multiplexing has e.....»»
The surface knows what lies beneath: Physicists show how to detect higher-order topological insulators
Just like a book can't be judged by its cover, a material can't always be judged by its surface. But, for an elusive conjectured class of materials, physicists have now shown that the surface previously thought to be "featureless" holds an unmistakab.....»»
Cosmic dawn observational progress with NenuFAR
The NenuFAR Cosmic Dawn project has taken an important step in the exploration of the Cosmic Dawn, this key period in our universe marked by the formation of the first stars. An upper limit on the amplitude of the neutral hydrogen fluctuations at 21.....»»
Water may have flowed intermittently in Martian valleys for hundreds of millions of years
Using impact craters as a dating tool, Planetary Science Institute Research Scientist Alexander Morgan has determined maximum timescales for the formation of Martian valley networks shaped by running water......»»
New research deciphers biomineralization mechanism
Many organisms can produce minerals or mineralized tissue. A well-known example is nacre, which is used in jewelry because of its iridescent colors. Chemically speaking, its formation begins with a mollusk extracting calcium and carbonate ions from w.....»»
More aerosol particles than thought are forming over Siberia, finds study
Aerosol particles play a key role in cooling the planet. They can either directly affect how much sunlight ends up on the surface of the Earth or indirectly through cloud formation, to which they contribute. New particles form from a variety of gas m.....»»
Using "Kerr solitons" to boost the power of transmission electron microscopes
When light goes through a material, it often behaves in unpredictable ways. This phenomenon is the subject of an entire field of study called "nonlinear optics," which is now integral to technological and scientific advances from laser development an.....»»
Astronomers find direct link that supernovae give rise to black holes or neutron stars
Astronomers have found a direct link between the explosive deaths of massive stars and the formation of the most compact and enigmatic objects in the universe—black holes and neutron stars. With the help of the European Southern Observatory's Very.....»»
Elucidating the process of bile duct formation in the liver
Bile ducts are pathways that carry hepatocyte-produced bile from the liver to the small intestine. In the human fetal liver, bile ducts are formed from bile duct epithelial cells surrounding the portal vein, and hepatocytes form on the outside. Both.....»»
Researchers discover how atmospheric feldspar dust contributes to cloud formation
Feldspar is a ubiquitous mineral and makes up about half of the Earth's crust. In the Earth's atmosphere, feldspars play a surprisingly important role. Fine powder carried by air influences cloud formation. Water molecules adhere better to feldspar d.....»»
