On Nov. 1, NASA’s Lucy spacecraft flew by not just its first asteroid, but its first two. The first images returned by Lucy reveal that the small main belt asteroid Dinkinesh is actually a binary pair. “Dinkinesh really did live up to its name; this is marvelous,” said Hal Levison, referring to the meaning of Dinkinesh in the Amharic language, “marvelous.” Levison is principal investigator for Lucy from the Boulder, Colorado, branch of the San-Antonio-based Southwest Research Institute. “When Lucy was originally…
Researchers demonstrate solution for long-term challenge. In a paper published recently in Advanced Science, researchers from the Paul Drude Institute in Berlin, Germany, and the Xiamen University, Xiamen, China, demonstrated that ferrimagnetic NiCo2O4 (NCO) constitutes a solution for the long-term challenge of finding materials with a robust out-of-plane magnetization. Furthermore, it is shown that the electrical and magnetic characteristics of NCO can be tailored in wide ranges. The research team also resolved the origin of an unusual fundamental magnetotransport phenomenon….
An innovative algorithm successfully addresses the challenge of microscopy resolution through pixel reassignment. Obtaining high-resolution images in the world of microscopy has long been a challenge. Deconvolution, a method to enhance image clarity, often amplifies noise between the sample and the image. Researchers at Boston University recently developed a novel deblurring algorithm that avoids these issues, improving the resolution of images with photon intensity conservation and local linearity. As reported in the Gold Open Access journal Advanced Photonics, the innovative deblurring…
The University of the Basque Country’s Planetary Sciences Group is leading the discovery made by an international team and based on the analysis of observations obtained by the James Webb Space Telescope. High-speed jet streams are a common feature in the atmospheres of many planets. On the Earth, jet streams form at various latitudes and meander around the planet, changing latitude and reaching speeds approaching 400 km/h at an altitude of over 10 km above the surface. On the giant…
WVU research explores 3D printing in microgravity. Research from West Virginia University students and faculty into how 3D printing works in a weightless environment aims to support long-term exploration and habitation on spaceships, the moon or Mars. Extended missions in outer space require the manufacture of crucial materials and equipment onsite, rather than transporting those items from Earth. Members of the Microgravity Research Team said they believe 3D printing is the way to make that happen. The team’s recent experiments focused on how a…
Exquisite, never-before-seen details help unravel the supernova remnant’s puzzling history. 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. Using Webb’s…
How they can prevent life in other solar systems. Giant gas planets can be agents of chaos, ensuring nothing lives on their Earth-like neighbors around other stars. New studies show, in some planetary systems, the giants tend to kick smaller planets out of orbit and wreak havoc on their climates. Jupiter, by far the biggest planet in our solar system, plays an important protective role. Its enormous gravitational field deflects comets and asteroids that might otherwise hit Earth, helping create…
… that affect satellite communications. A study from an international team led by researchers from Nagoya University in Japan and the University of New Hampshire in the United States has revealed the importance of the Earth’s upper atmosphere in determining how large geomagnetic storms develop. Their findings reveal the previously underestimated importance of the Earth’s atmosphere. Understanding the factors that cause geomagnetic storms is important because they can have a direct impact on the Earth’s magnetic field such as causing…
Columbia chemists discover ballistic flow in a quantum material. The finding could help overcome shortcomings in semiconductors. Semiconductors—most notably, silicon—underpin the computers, cellphones, and other electronic devices that power our daily lives, including the device on which you are reading this article. As ubiquitous as semiconductors have become, they come with limitations. The atomic structure of any material vibrates, which creates quantum particles called phonons. Phonons in turn cause the particles—either electrons or electron-hole pairs called excitons—that carry energy and…
Aalto University researchers will probe the secrets of dark matter using a quantum detector of unprecedented sensitivity. In the pitch dark of the cosmos lurks an invisible kind of matter. Its presence is seen in the rippling ebb and flow of galaxies, but it’s never been directly observed. What secrets lie beneath the surface, brewing in the deep? Physicists have long theorized about the composition of dark matter, which is thought to be five times more abundant than regular matter….
Quantum physicists at Delft University of Technology have shown that it’s possible to control and manipulate spin waves on a chip using superconductors for the first time. These tiny waves in magnets may offer an alternative to electronics in the future, interesting for energy-efficient information technology or connecting pieces in a quantum computer, for example. The breakthrough, published in Science, primarily gives physicists new insight into the interaction between magnets and superconductors. Energy-efficient substitute “Spin waves are waves in a…
In physics, quasiparticles are used to describe complex processes in solids. In ultracold quantum gases, these quasiparticles can be reproduced and studied. Now, for the first time, Austrian scientists led by Rudolf Grimm have been able to observe in experiments how Fermi polarons – a special type of quasiparticle – can interact with each other. Their findings have been published in Nature Physics. An electron moving through a solid generates a polarization in its environment due to its electric charge….
Using a network of radio telescopes on Earth and in space, astronomers have captured the most detailed view ever of a jet of plasma from a supermassive black hole. The jet travels at nearly the speed of light and shows complex, twisted patterns near its source. These patterns challenge the standard theory that has been used for 40 years to explain how these jets form and change over time. A major contribution to the observations was made possible by the…
New Quantum Effect Demonstrated for the First Time. For the first time, experimental physicists from the Würzburg-Dresden Cluster of Excellence ct.qmat have demonstrated a new quantum effect aptly named the “spinaron.” In a meticulously controlled environment and using an advanced set of instruments, they managed to prove the unusual state a cobalt atom assumes on a copper surface. This revelation challenges the long-held Kondo effect – a theoretical concept developed in the 1960s, and which has been considered the standard…
Astrophysicists scan the Galaxy for signs of life. Astrophysicists from Trinity College Dublin are scanning the Universe for “technosignatures” emanating from distant planets that would provide support for the existence of intelligent, alien life. Using the Irish LOFAR telescope and its counterpart in Onsala, Sweden, the team – led by Professor Evan Keane, Associate Professor of Radio Astronomy in Trinity’s School of Physics, and Head of the Irish LOFAR Telescope – plans to monitor millions of star systems. Scientists have been…
Team of researchers headed by physicists Prof. Wolfram Pernice and Prof. Martin Salinga and computer specialist Prof. Benjamin Risse, all from the University of Münster, has developed a so-called event-based architecture, using photonic processors. In a similar way to the brain, this makes possible the continuous adaptation of the connections within the neural network. Modern computer models – for example for complex, potent AI applications – push traditional digital computer processes to their limits. New types of computing architecture, which…
