After starting science operations in February, Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) studied the monster black hole at the center of galaxy NGC4151.

“XRISM’s Resolve instrument captured a detailed spectrum of the area around the black hole,” said Brian Williams, NASA’s project scientist for the mission at the agency’s Goddard Space Flight Center in Greenbelt, Maryland. “The peaks and dips are like chemical fingerprints that can tell us what elements are present and reveal clues about the fate of matter as it nears the black hole.”

XRISM (pronounced “crism”) is led by JAXA (Japan Aerospace Exploration Agency) in collaboration with NASA, along with contributions from ESA (European Space Agency). It launched Sept. 6, 2023. NASA and JAXA developed Resolve, the mission’s microcalorimeter spectrometer.

Microscopic chinks in material just several atoms thick have the potential to advance a multitude of quantum technologies, new research shows – getting us closer to the widespread use of quantum networks and sensors.

Right now, storing quantum data in the spin properties of electrons, known as spin coherence, requires a very particular and delicate laboratory setup. It’s not something you can do without a carefully controlled environment.

Here, an international team of researchers managed to demonstrate observable spin coherence at room temperature, using the tiny defects in a layered 2D material called Hexagonal Boron Nitride (hBN).

Group theory and first-principles calculations combine to predict which antiferromagnets have potentially useful net surface magnetization.

Antiferromagnetism was discovered in the 1930s by Louis Néel but had long been considered of scientific, not practical, interest. Antiferromagnets (AFM) are internally magnetic, but the magnetic moments of their atoms and molecules are antiparallel to each other, canceling out and resulting in no net magnetization. This cancellation renders bulk antiferromagnets effectively invisible to external magnetic fields, so that their magnetic properties are difficult to harness in applications. Recently, however, a new paradigm has appeared—antiferromagnetism-based spintronics—which seeks to apply antiferromagnets’ unique properties (such as fast spin dynamics, the absence of strong stray fields, and the stability of these materials) to the processing and storage of information [1].

A thin film of a topological magnet displays a large thermoelectric effect that doesn’t require an applied magnetic field—a behavior that could lead to new energy-harvesting devices.

A planet thought to orbit the star 40 Eridani A—host to Mr. Spock’s fictional home planet, Vulcan, in the “Star Trek” universe—is really a kind of astronomical illusion caused by the pulses and jitters of the star itself, a new study shows.

A research team at Stanford’s Wu Tsai Neurosciences Institute has made a major stride in using AI to replicate how the brain organizes sensory information to make sense of the world, opening up new frontiers for virtual neuroscience.

A 3D model developed by West Virginia University neuroscientists shows how implantable stimulators—the kind used to treat chronic pain—can target neurons that control specific muscles to provide rehabilitation for people with neurological disorders such as stroke and spinal cord injuries.

Materials scientists and engineers would like to know precisely how electrons interact and move in new materials and how the devices made with them will behave. Will the electrical current flow easily within the material? Is there a temperature at which the material will become superconducting, enabling current to flow without a power source? How long will the quantum state of an electron spin be preserved in new electronic and quantum devices?
