A team of researchers led by the University of Warwick has developed the first unified framework for detecting “spacetime fluctuations”—tiny, random distortions in the fabric of spacetime that appear in many attempts to unite quantum physics and gravity.
Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of Vienna answers this question with a resounding yes. In the journal Nature, physicists from the University of Vienna and the University of Duisburg-Essen show that even massive nanoparticles consisting of thousands of sodium atoms follow the rules of quantum mechanics. The experiment is currently one of the best tests of quantum mechanics on a macroscopic scale.
Baby pictures are some of a family’s most cherished artifacts. The same thing can be said of the Hubble Space Telescope and the infant stars it immortalizes in its scientific portraits. But while we know how babies are conceived and how they form in great detail, the same can’t be said for star formation.
To land on the right foot on the Red Planet, European engineers have been dropping a skeleton of the four-legged ExoMars descent module at various speeds and heights on simulated Martian surfaces.
Astronomers from the National Research Institute of Astronomy and Geophysics (NRIAG) in Cairo, Egypt, have investigated a young open cluster known as Czernik 38. As a result, they found a new open cluster, which turns out to be a companion to Czernik 38. The discovery was detailed in a paper published Jan. 14 on the arXiv pre-print server.
How can scientists estimate the pH level of Enceladus’ subsurface ocean without landing on its surface? This is what a study recently posted to the arXiv preprint server hopes to address as a team of scientists from Japan investigated new methods for sampling the plumes of Enceladus and have provided more accurate measurements of its pH levels. This study has the potential to help scientists better understand the subsurface ocean conditions on Enceladus and whether it’s suitable for life as we know it.
Buzz Aldrin, the second man and only one of 12 to ever walk on the moon, turns 96 today. He’s just one of four living moonwalkers and the oldest remaining astronaut still making trips around the sun.
In a new study, an international group of researchers has found that chiral phonons can create orbital current without needing magnetic elements—in part because chiral phonons have their own magnetic moments. Additionally, this effect can be achieved in common crystal materials. The work has potential for the development of less expensive, energy-efficient orbitronic devices for use in a wide array of electronics.
A research group has achieved a new plasma confinement regime using small 3D magnetic perturbations that simultaneously suppress edge instabilities and enhance core plasma confinement in the Experimental Advanced Superconducting Tokamak (EAST). The research results are published in PRX Energy.
All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the solar wind, high-energy particle transport, and galaxy formation. Small-scale magnetic fields are generally turbulent and chaotic, yet large-scale fields are organized, a phenomenon that plasma astrophysicists have tried explaining for decades, unsuccessfully.
Quantum technologies, systems that process, transfer or store information leveraging quantum mechanical effects, could tackle some real-world problems faster and more effectively than their classical counterparts. In recent years, some engineers have been focusing their efforts on the development of quantum communication systems, which could eventually enable the creation of a “quantum internet” (i.e., an equivalent of the internet in which information is shared via quantum physical effects).
In a recent study, researchers from China have developed a chip-scale LiDAR system that mimics the human eye’s foveation by dynamically concentrating high-resolution sensing on regions of interest (ROIs) while maintaining broad awareness across the full field of view.
Even very slight environmental noise, such as microscopic vibrations or magnetic field fluctuations a hundred times smaller than Earth’s magnetic field, can be catastrophic for quantum computing experiments with trapped ions.
Holyoke Councilor Israel Rivera told officers, “You know who the (expletive) I am? I’m not a regular (racial slur),” and later, “I’m the one that makes your (expletive) budget (racial slur).”
The funding request of $25.9 million includes resources for two 72-person training academies and would support the addition of 100 new troopers
