Two UCalgary researchers part of University of New South Wales team that created a 'Schrödinger's cat' inside a silicon chip A team led by quantum engineers at the University of New South Wales - that includes two UCalgary researchers - has demonstrated a well-known quantum thought experiment in the real world.

Quantum simulators are a completely new tool for research: quantum physics is studied by other kinds of quantum physics. Research teams from Innsbruck and Vienna are developing a new method that will allow this new technology to be reliably verified. Quantum physics is a very diverse field: it describes particle collisions shortly after the Big Bang as well as electrons in solid materials or atoms far out in space.

The work opens new avenues for understanding and manipulating electrons in materials. MIT physicists and colleagues have for the first time measured the geometry, or shape, of electrons in solids at the quantum level. Scientists have long known how to measure the energies and velocities of electrons in crystalline materials, but until now, those systems' quantum geometry could only be inferred theoretically, or sometimes not at all.

The size and spin of black holes can reveal important information about how and where they formed, according to new research. The study, led by scientists at Cardiff University, tests the idea that many of the black holes observed by astronomers have merged multiple times within densely populated environments containing millions of stars.

Scientists have successfully achieved a quantum collective behavior of macroscopic mechanical oscillators, unlocking new possibilities in quantum technology. Quantum technologies are radically transforming our understanding of the universe. One emerging technology are macroscopic mechanical oscillators, devices that are vital in quartz watches, mobile phones, and lasers used in telecommunications.

Life on Earth could not exist without carbon. But carbon itself could not exist without stars. Nearly all'elements except hydrogen and helium - including carbon, oxygen and iron - only exist because they were forged in stellar furnaces and later flung into the cosmos when their stars died. In an ultimate act of galactic recycling, planets like ours are formed by incorporating these star-built atoms into their makeup, be it the iron in Earth's core, the oxygen in its atmosphere or the carbon in the bodies of Earthlings.

McGill-led research team's findings point to neutron stars as the probable source of fast radio bursts, one of the universe's most perplexing phenomena   An international team of scientists led by McGill researchers has provided the clearest evidence yet that some fast radio bursts (FRBs) - enigmatic, millisecond-long flashes of radio waves from space - originate from neutron stars, the ultra-dense remnants of massive stars that have exploded in a supernova.

The fleeting cosmic firework likely emerged from the turbulent magnetosphere around a far-off neutron star. Fast radio bursts are brief and brilliant explosions of radio waves emitted by extremely compact objects such as neutron stars and possibly black holes. These fleeting fireworks last for just a thousandth of a second and can carry an enormous amount of energy - enough to briefly outshine entire galaxies.

The missing ingredient for cooking up stars has been spotted for the first time by an international team led by astronomers at Imperial College. Much like a pressure cooker has a weight on top of its lid to keep the pressure in and get your festive dessert dense, moist and ready to eat, merging galaxies may need magnetic fields to create the ideal conditions for star formation.

This year, Lawrence Berkeley National Laboratory (Berkeley Lab) led research that pushes the boundaries of science and technology. From advancing our understanding of the universe to innovations in microelectronics, artificial intelligence, quantum science, and biomanufacturing, the lab's teams have achieved remarkable milestones across diverse fields.

New observations with the James Webb Space Telescope no longer rule out the presence of an atmosphere around the Earth-sized rocky planet. However, a geologically active planet also explains the data. Recent measurements with the James Webb Space Telescope (JWST) cast doubt on the current understanding of the exoplanet Trappist-1 b-s nature.

A high-energy gamma-ray flare from the super-massive black hole in the Messier 87 (M87) galaxy was observed in 2018 for the first time in nearly a decade, thanks to an international effort involving McGill researchers. This discovery has yielded important insights into the physics of black hole jets, which are among the most efficient engines for distributing energy from the inside of a galaxy to the expanse of the Universe.

Researchers at the Autonomous University of Madrid (UAM) and CSIC have developed an innovative technique that combines ion implantation and femtosecond lasers to create advanced optical nanocomposites. The work, published in Materials Today Nano , lays the groundwork for a new generation of customizable materials with applications in optics, sensors and photonics.

Key Takeaways Laser-plasma accelerators could someday significantly reduce the size and cost of particle accelerators used in high-energy physics, medicine, materials science, and beyond. BELLA researchers used a petawatt laser to reach a key laser-plasma accelerator milestone: accelerating a high-quality 10-GeV electron beam in 30 centimeters, a significant improvement in both energy and quality compared to previous efforts.

Bonn researchers decipher structure of coagulation factor XIII using cryo-electron microscopy A deficiency in blood plasma coagulation factor XIII leads to a disruption in the cross-linking of fibrin, the "glue" in blood coagulation. The enzyme therefore plays an essential role in blood clotting. Researchers at the University Hospital Bonn (UKB) and the University of Bonn, together with Thermo Fisher Scientific in the Netherlands, deciphered the previously unknown structure of the Factor XIII complex using cryo-electron microscopy (cryo-EM), even at the atomic level.

Space mission "BepiColombo" delivers data from the innermost planet in our solar system for the first time On December 1, 2024, the BepiColombo mission flew past Mercury for the fifth time and has now become the first spacecraft to observe the surface in the mid-infrared using the MERTIS ("Mercury Radiometer and Thermal Infrared Spectrometer") infrared spectrometer.

A Spanish team led from the Autonomous University of Madrid (UAM) has observed the formation of a new quantum state in ultrathin materials by cooling a Mott insulator below 11 Kelvin. This finding, published in Nature Communications , could revolutionize the development of superconductors and next-generation electronic devices, marking a milestone in materials science.

Identifying optimal catalyst materials for specific reactions is crucial to advance energy storage technologies and sustainable chemical processes. To screen catalysts, scientists must understand systems' adsorption energy, something that machine learning (ML) models, particularly graph neural networks (GNNs), have been successful at predicting.
