Using NASA’s SPHEREx space telescope, astronomers have observed remnants of the eruption of Nova Persei 1901. As a result, they detected a bipolar molecular hydrogen shell around this nova, which may be a large planetary nebula. The finding was detailed in a paper published March 13 on the arXiv pre-print server. Go to Source […] The performance of quantum computers could cap out after around 1,000 qubits, according to a new analysis published in the Proceedings of the National Academy of Sciences. Through new calculations, Tim Palmer at the University of Oxford has reconsidered the mathematical foundations underlying the quantum principles behind the technology, concluding that restrictions on the information-carrying […] A fire truck responding to a separate incident was struck by a passenger jet as it landed; the pilot and copilot were killed, and two Port Authority Police officers were treated for broken bones Go to Source A research team has discovered a new way to control tiny magnetic properties inside materials using electric current, which could possibly pave the way for new types of computing technologies. The work is based on spintronics, a field that uses not only the electric charge of electrons but also their “spin,” a quantum property that […] Quantum computers, computing systems that process information using quantum mechanical effects, could outperform classical computers on some computational tasks. These computers rely on qubits, the basic units of quantum information, which can exist in multiple states (0, 1 or both simultaneously), due to quantum effects known as superposition and entanglement. Go to Source […] A team of astronomers led by the Center for Astrophysics | Harvard and Smithsonian have for the first time used galactic archaeology, the study of detailed chemical fingerprints in deep space, to trace the history of a galaxy outside the Milky Way. The study, published in Nature Astronomy, demonstrates a new way to reconstruct the […] Russia has launched a rocket from Site 31 of the Baikonur Cosmodrome for the first time since it was damaged during a liftoff last November, video from Russia’s Roscosmos space agency showed Sunday. Go to Source Class B; August 2022; Maine, Piscataquis County Go to Source A new study reveals all five fundamental nucleobases—the molecular “letters” of life—have been detected in samples from the asteroid Ryugu. Go to Source Many current wireless communication, imaging and sensing technologies rely on components that convert oscillating electric and magnetic fields (i.e., electromagnetic waves) into electrical signals. Some of the most used components are so-called p-n diodes, semiconducting devices that combine two types of materials with distinct electrical properties. Go to Source Police officers supporting the bill argued that technically, police officers are not allowed to bring weapons on school property even while picking up their own children Go to Source Class B; March 2026; Ohio, Ashland County Go to Source Sixty years after Neil Armstrong barely survived an emergency in orbit around Earth on Gemini 8, never-before-seen photos of his heroic return have been donated to the Ohio museum that bears his name. Go to Source Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a nearby spiral galaxy known as NGC 628. Results of the observational campaign, published March 10 on the arXiv pre-print server, shed more light on the population of emerging young star clusters in this galaxy. Go to Source […] Researchers have proposed that a newly identified class of magnetic materials could extend the zero-resistance currents of superconductors to electron spins. Publishing their calculations in Physical Review X, Kyle Monkman and colleagues at the University of British Columbia propose how “altermagnets” could enable persistent spin currents to flow without dissipation. If confirmed experimentally, the effect […] |
