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.
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 evolution of distant galaxies, and opens up a new field of astronomy, called “extragalactic archaeology.”
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.

A new study reveals all five fundamental nucleobases—the molecular “letters” of life—have been detected in samples from the asteroid Ryugu.
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.

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.
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.
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 could provide a powerful new platform for spintronics, where information is encoded in spin rather than electric charge.
Provided they host thick, hydrogen-dominated atmospheres, moons orbiting free-floating exoplanets could retain much of the heat generated deep within their interiors by tidal forces. Led by David Dahlbüdding at the Max Planck Institute for Extraterrestrial Physics and Giulia Roccetti at the European Space Agency, a new study predicts that hydrogen could act as a potent greenhouse gas—potentially providing habitable conditions for billions of years after their host planets are first ejected from their stellar systems. The work has been published in Monthly Notices of the Royal Astronomical Society.
Trooper Aaron Pelletier was struck and killed while conducting a traffic stop on May 30, 2024; the Tunnels to Towers Foundation paid for the home of his wife and two sons
Michigan State Police troopers and a U.S. Border Patrol agent guided the horse to a nearby barn, which turned out to be on the farm neighboring its home
Physicists have directly visualized the fundamental electronic building blocks of flat-band quantum materials, a class of systems in which electron motion is effectively quenched and strong interactions give rise to emergent phases of matter. In a study published in Nature Physics, Qimiao Si’s group at Rice University, in collaboration with researchers at the Weizmann Institute of Science, identified compact molecular orbitals that act as the key electronic agents governing the exotic behavior of these materials.
