Quantum skyrmions outlast entanglement, hinting at more resilient networks

Quantum networks could one day connect quantum computers into more powerful systems and enable new forms of secure communication. But a fundamental obstacle stands in the way: Quantum information is extraordinarily fragile, and the entanglement between particles of light on which such networks would depend is easily disrupted.

NASA’s Voyager 1 conserves power, resolves brief communications pause

NASA’s Voyager team is celebrating two recent developments with the Voyager 1 spacecraft: In September, they successfully completed a months-long effort to stretch the spacecraft’s diminishing power supply. Then, on Oct. 20, an unexpected loss of communication with the spacecraft resolved itself after 48 hours, before the team sent commands to the spacecraft to troubleshoot the issue.

JWST reveals a distant galaxy that may let most of its ionizing radiation escape

Astronomers using the James Webb Space Telescope (JWST) have found evidence that a distant, exceptionally blue galaxy may allow most of its ionizing radiation to escape into space. Known as EBG-1, the gravitationally lensed galaxy is seen at a redshift of 9.244, about 530 million years after the Big Bang. The paper was posted to the arXiv preprint server on Oct. 16.

NASA’s TRACERS first results offer peek into violent magnetic process

NASA’s TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission has gathered its first clues to how space weather affects Earth’s magnetic field. In a new paper published in the Journal of Geophysical Research: Space Physics, researchers break down how these interactions work after analyzing initial observations from the first year of the mission.

Extraterrestrial detection inspired by firefly communications could distinguish alien signals from pulsars

When we think of extraterrestrial intelligence that might be out there among the stars, we tend to think of creatures not too unlike us, though maybe with gray skin, probably bald and with big black eyes. We focus on the familiar, humanoids. But there are many intelligent species on Earth that are nonhumanoid: dolphins, crows, pigs and—with swarm if not individual intelligence—ants and bees. The film “Arrival” conceived of hexapod beings more capable than humans and with a more sophisticated communication system.

Confirming altermagnetism: A geometric twist offers experimental proof

For decades, physicists recognized only two types of magnetism that occur in materials without external influence: ferromagnetism and antiferromagnetism. In findings published in Science, a team led by the U.S. Department of Energy’s SLAC National Accelerator Laboratory has delivered conclusive experimental proof of a third magnetic phase called altermagnetism.

Small molecular twists may strengthen nature’s magnetic compass

A collaborative research team led by Yasuhiro Kobori at Kobe University, together with researchers from Toho University, Saitama University, Nagoya Institute of Technology and the University of Freiburg, has identified a potential molecular mechanism that could enhance magnetic compass responses in cryptochrome, a blue-light-sensitive protein implicated in magnetoreception.

New X-ray method isolates faint signals from water at material surfaces

A research team from Toyohashi University of Technology, the Institute for Molecular Science and the Institute of Science Tokyo, led by Yu Kinjo and professor Ryugo Tero of Toyohashi University of Technology, has developed a new method to investigate the state of water near material surfaces using X-rays. By combining X-ray absorption spectroscopy with data analysis, the researchers separated the weak signals of interfacial water from those of the much larger amount of surrounding water.

NASA’s new UV space telescope will launch in 2031

Most of us could spend our entire lives looking at the night sky and see very few changes. The moon becomes more or less illuminated, the planets drift placidly through the sky, satellites and the ISS intrude for a few moments at a time, and the bright, momentary streak of a meteor punctuates the occasional evening of stargazing.

Rare 4.1-billion-year-old Martian meteorite reveals clues to planet’s ancient past

Scientists at the University of New Mexico have played a key role in identifying a rare, 4.1-billion-year-old Martian meteorite that provides new evidence that the red planet may have once had a wetter, Earth-like environment.
