Researchers Achieve Interdimensional Superconductivity
Although electrons usually move in three dimensions, scientists can force electrons to move in two dimensions (2D) by creating ultra-thin materials. In this new work, however, researchers found that by adding superconductivity to 3D electrons in a bulk material, the superconducting electrons form 2D superconducting "puddles." These puddles of electrons may be a way for some superconductors to reorganize themselves before undergoing an abrupt phase transition into an insulating state.

Scientists use ORNL's Summit supercomputer to learn how cicada wings kill bacteria
Over the past decade, teams of engineers, chemists and biologists have analyzed the physical and chemical properties of cicada wings, hoping to unlock the secret of their ability to kill microbes on contact.

Droplet Levitation Is a New Way To Explore Airborne Viruses and Microorganisms
In Applied Physics Letters, researchers report achieving self-sustaining and long-term levitation of millimeter-sized droplets of several different liquids without any external forces. To get the droplets to levitate, they use solutocapillary convection, which occurs when a surface tension gradient is formed by nonuniform distribution of vapor molecules from the droplet at the pool surface.
Three UAH researchers operating Gamma-ray Burst Monitor discover brightest gamma-ray burst ever detected
The University of Alabama in Huntsville (UAH) has announced that three researchers associated with the UAH Center for Space Plasma and Aeronomic Research (CSPAR) have discovered a gamma-ray burst (GRB) approximately 2.4 billion light-years away in the constellation Sagitta that ranks as the brightest ever observed. Believed to have been triggered by collapse of a massive star, it is accompanied by a supernova explosion, giving birth to a black hole.

Halide Perovskite Material Exhibits Liquid-Like Atomic Vibrations
Halide perovskites have applications in solar energy, radiation detection, and potentially in thermal harvesting. Cesium lead bromide is among the simplest of lead halide perovskite materials (LHPs). New research examined structural instabilities and large atomic fluctuations that may affect LHPs' optical and thermal properties. It found that the atomic vibrations (phonons) of bromine octahedrons have large amplitudes but cannot oscillate for long amounts of time. Instead, the vibrations are strongly damped.

Una jarra cosmica desbordando material estelar
Una serie de nubes simetricas y ondulantes de polvo y gas marcan la agonica muerte de una antigua estrella gigante roja, tal como lo muestra esta imagen obtenida en Chile por el telescopio Gemini Sur, parte del Observatorio Internacional Gemini, operado por AURA y NOIRLab de NSF. La estructura resultante, que se dice se parece a una jarra inglesa de estilo antiguo, es una nebulosa de reflexion bipolar que rara vez es posible de apreciar. La evidencia sugiere que este objeto se formo por las interacciones entre la estrella gigante roja moribunda y una estrella companera destrozada hace mucho.
Rare, Double-Lobe Nebula Resembles Overflowing Cosmic 'Jug'
A billowing pair of nearly symmetrical loops of dust and gas mark the death throes of an ancient red-giant star, as captured by Gemini South, one half of the International Gemini Observatory, operated by NSF's NOIRLab. The resulting structure, said to resemble an old style of English jug, is a rarely seen bipolar reflection nebula. Evidence suggests that this object formed by the interactions between the dying red giant and a now-shredded companion star.
