Published Milky Way-like galaxy found in the early universe



Astronomers have discovered the most distant barred spiral galaxy, similar to the Milky Way, that has been observed to date.
Published Glow in the visible range detected for the first time in the Martian night



Scientists have observed, for the first time in the visible range, a glow on the night side of the planet Mars. These new observations provide a better understanding of the dynamics of the upper atmosphere of the Red Planet and its variations throughout the year.
Published Understanding the dynamic behavior of rubber materials



Rubber-like materials can exhibit both spring-like and flow-like behaviors simultaneously, which contributes to their exceptional damping abilities. To understand the dynamic viscoelasticity of these materials, researchers have recently developed a novel system that can conduct dynamic mechanical analysis and dynamic micro X-ray computed tomography simultaneously. This technology can enhance our understanding of the microstructure of viscoelastic materials and pave the way for the development of better materials.
Published 'Hot' new form of microscopy examines materials using evanescent waves



A team of researchers has built a prototype microscope that does not rely on backscattered radiation, instead uses passive detection of thermally excited evanescent waves. They have examined dielectric materials with passive near-field spectroscopy to develop a detection model to further refine the technique, working to develop a new kind of microscopy for examining nanoscopic material surfaces.
Published Studies of geologic faulting on icy moons aid exploration of extraterrestrial watery worlds



Earth and space scientists document and reveal the mechanisms behind strike-slip faulting on the largest moon of Saturn, Titan, and Jupiter's largest moon, Ganymede.
Published Mystery resolved: Black hole feeding and feedback at the center of an active galaxy



Almost every large galaxy has a supermassive black hole at its center. An international research team has recently observed the Circinus galaxy, which is one of the closest galaxies to the Milky Way, with high enough resolution to gain further insights into the gas flows to and from the black hole at its galactic nucleus.
Published Researchers develop solid-state thermal transistor for better heat management



A team of researchers has unveiled a first-of-its-kind stable and fully solid-state thermal transistor that uses an electric field to control a semiconductor device's heat movement. The group's study details how the device works and its potential applications. With top speed and performance, the transistor could open new frontiers in heat management of computer chips through an atomic-level design and molecular engineering. The advance could also further the understanding of how heat is regulated in the human body.
Published Black holes are messy eaters



New observations down to light-year scale of the gas flows around a supermassive black hole have successfully detected dense gas inflows and shown that only a small portion (about 3 percent) of the gas flowing towards the black hole is eaten by the black hole. The remainder is ejected and recycled back into the host galaxy.
Published Stronger, stretchier, self-healing plastic



An innovative plastic, stronger and stretchier than the current standard type and which can be healed with heat, remembers its shape and partially biodegradable, has been developed. They created it by adding the molecule polyrotaxane to an epoxy resin vitrimer, a type of plastic. Named VPR, the material can hold its form and has strong internal chemical bonds at low temperatures.
Published Underground car parks heat up groundwater



The heat given off by car engines warms up underground car parks in such a way that the heat passes through the ground into the groundwater. In Berlin alone, enough energy is transferred to the groundwater to supply 14,660 households with heat. According to the researchers, this warming could have long-term effects on groundwater quality. In their study, they also propose a solution. Using geothermal energy and heat pumps, the heat could be extracted from the ground and utilized.
Published What a '2D' quantum superfluid feels like to the touch



Researchers have discovered how superfluid helium 3He would feel if you could put your hand into it. The interface between the exotic world of quantum physics and classical physics of the human experience is one of the major open problems in modern physics. Nobody has been able to answer this question during the 100-year history of quantum physics.
Published Exploding stars



When massive stars or other stellar objects explode in the Earth's cosmic neighborhood, ejected debris can also reach our solar system. Traces of such events are found on Earth or the Moon and can be detected using accelerator mass spectrometry, or AMS for short.
Published In a surprising finding, light can make water evaporate without heat



At the interface of water and air, light can, in certain conditions, bring about evaporation without the need for heat, according to a new study.
Published The remains of an ancient planet lie deep within Earth



The remnants of an ancient planet that collided with Earth to form the Moon lie deep within the earth, according to a new model.
Published New twist on optical tweezers



Optical tweezers use laser light to manipulate small particles. A new method has been advanced using Stampede2 supercomputer simulations that makes optical tweezers safer to use for potential biological applications, such as cancer therapy.
Published The Crab Nebula seen in new light by NASA's Webb



NASA's James Webb Space Telescope has gazed at the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. Since the recording of this energetic event in 1054 CE by 11th-century astronomers, the Crab Nebula has continued to draw attention and additional study as scientists seek to understand the conditions, behavior, and after-effects of supernovae through thorough study of the Crab, a relatively nearby example.
Published A sustainable alternative to air conditioning



As the planet gets hotter, the need for cool living environments is becoming more urgent. But air conditioning is a major contributor to global warming since units use potent greenhouse gases and lots of energy. Now, researchers have found in a new study an inexpensive, sustainable alternative to mechanical cooling with refrigerants in hot and arid climates, and a way to mitigate dangerous heat waves during electricity blackouts.
Published To advance space colonization, new research explores 3D printing in microgravity



Research into how 3D printing works in a weightless environment aims to support long-term exploration and habitation on spaceships, the moon or Mars.
Published 3D printed reactor core makes solar fuel production more efficient



Using a new 3D printing technique, researchers have developed special ceramic structures for a solar reactor. Initial experimental testing show that these structures can boost the production yield of solar fuels.
Published Uranus aurora discovery offers clues to habitable icy worlds



Astronomers confirm the existence of an infrared (IR) aurora on Uranus. This could help astronomers identify exoplanets that might support life, a large number of which are icy worlds.
