A study by researchers from the University of British Columbia’s Blusson Quantum Matter Institute (UBC Blusson QMI) has found a rare form of one-dimensional quantum magnetism in the metallic compound Ti4MnBi2, offering evidence into a phase space that has remained, until now, largely theoretical.
The study, published in Nature Materials, comes at a time of growing global interest in quantum materials that redefine the boundaries between magnetism, conductivity, and quantum coherence.
“We proved the existence of a new class of quantum materials that are both metallic and one-dimensional magnets, with strong coupling between the magnetic moments and their metallic host,” said UBC Blusson QMI Investigator Prof. Meigan Aronson.
In a future of limitless resources, what challenges remain when scarcity fades but human desires endure? Join us as we explore the path to post-scarcity civilizations, where technology solves material needs—but purpose, meaning, and new challenges await.

WASHINGTON (Reuters) –In a potential landmark discovery, scientists using the James Webb Space Telescope have obtained what they call the strongest signs y
Astronomers have discovered a planet that orbits at a 90-degree angle around a rare pair of strange stars—a real-life ‘twist’ on the fictional twin suns of Star Wars hero Luke Skywalker’s home planet of Tatooine.
The exoplanet, named 2M1510 (AB) b, orbits a pair of young brown dwarfs —objects bigger than gas-giant planets but too small to be proper stars. Only the second pair of eclipsing brown dwarfs known—this is the first exoplanet found on a right-angled path to the orbit of its two host stars.
An international team of researchers led by the University of Birmingham made the surprise discovery using the European Southern Observatory’s Very Large Telescope (VLT). The brown dwarfs produce eclipses of one another, as seen from Earth, making them part of an “eclipsing binary.”
A pair of physicists at Universidad Nacional de Mar del Plata, in Argentina, have created a computer simulation of the famed Antikythera Mechanism and in so doing have found that manufacturing inaccuracies may have caused the device to jam so often it would have been very nearly unusable—if it was in the condition it is now. Esteban Szigety and Gustavo Arenas have posted a paper on the arXiv preprint server describing the factors that went into their simulation and what it showed.
In 1901, divers looking for sponges off the coast of the Greek island, Antikythera, discovered a mechanical device among the ruins of a sunken ship. The mysterious device was dated to the late second or early first century BCE, and from that time on there has been much debate in the scientific community regarding its purpose.
Some markings on the device suggest it could be used to track time and astronomical events and even predict some others, such as the arrival of a comet, courtesy of its intricate gears and pointing indicators, by turning its hand crank. Since only one of the devices has ever been found, some have suggested it had an otherworldly origin.
Euclid’s first data release offers a breathtaking glimpse into our universe, revealing over 26 million galaxies and showcasing the telescope’s unprecedented precision in the visible and infrared. Powered by advanced optics and massive data processing infrastructure, the mission is already revolut
Highly magnetic neutron star is wandering our Milky Way galaxy. Astronomers using NASA’s Hubble Space Telescope have tracked a rare and fast-moving magnetar – called SGR 0501+4516 – as it speeds through the Milky Way. Its origin remains unknown, and based on current data, it may be the best evidenc
A QUT-led study analyzing data from NASA’s Perseverance rover has uncovered compelling evidence of multiple mineral-forming events just beneath the Martian surface—findings that bring scientists one step closer to answering the profound question: did life ever exist on Mars?
The QUT research team led by Dr. Michael Jones, from the Central Analytical Research Facility and the School of Chemistry and Physics, includes Associate Professor David Flannery, Associate Professor Christoph Schrank, Brendan Orenstein and Peter Nemere, together with researchers from North America and Europe.
The paper, “In-situ crystallographic mapping constrains sulfate precipitation and timing in Jezero crater, Mars” is published in Science Advances.
