Controlling magnetic chirality could help memory pack in more data

Magnetic storage devices, like a computer’s hard disk drive, utilize magnets to represent binary data. However, as these devices are downsized, stray magnetic fields generated by individual magnetic components can interact with neighboring elements to cause operational malfunctions, limiting how much data we can densely pack into memory devices.

Optical writing of antiferromagnets points toward new storage devices and energy efficient information systems

A German-Japanese research team involving the University of Augsburg has made a significant breakthrough in the use of antiferromagnets. For the first time, the team has succeeded in writing magnetic information using only ultrashort laser pulses—without the need for electric currents or magnetic fields.

Astronomers may have caught an early galaxy in the process of dying

Astronomers have spotted many “red and dead” galaxies in the early universe. These are massive systems that stopped forming stars surprisingly early in cosmic history. Now, they may have found evidence of one in the act of becoming dead: a massive galaxy being stripped of its star-forming gas just 1.4 billion years after the Big […]

Plug-and-play single-photon source can work at room temperature

The Korea Research Institute of Standards and Science (KRISS) has developed a room-temperature single-photon source built into a compact 19-inch rack-mounted device that operates without cryogenic cooling. Designed as a plug-and-play system that works as soon as it is powered on, the device moves quantum light source technology beyond the laboratory and closer to practical, […]

Hot Jupiter winds reveal exoplanet magnetic fields for first time

Planets beyond our solar system can have magnetic fields similar to those closer to home, astronomers said Tuesday after observing extreme winds on scorching worlds known as “hot Jupiters.”

Ultrafast scanning tunneling microscopy reaches the quantum mechanical space-time limit for the first time

Werner Heisenberg’s famous uncertainty principle describes one of the most intriguing features of quantum physics: certain pairs of physical quantities describing a particle, such as position and momentum, cannot simultaneously be determined with arbitrary precision—not because of imprecise measuring instruments, but because nature forbids it. Between position and time, however, there is no Heisenberg uncertainty […]

Long-lived radio outburst from black hole exhibits properties of the early universe

Short-lived sources of radio radiation in the sky, known as radio transients, can originate in the vicinity of supermassive black holes in the centers of galaxies. They are the result of processes that take place under extreme physical conditions. While most radio transients associated with galactic centers last only days or weeks, the galaxy SDSS […]

JWST discovers a new barred spiral galaxy

An international team of astronomers reports the discovery of a new massive barred spiral galaxy. The newfound galaxy, designated M1149-BSG-z5, was identified using the James Webb Space Telescope (JWST). The finding was detailed in a paper published June 23 on the preprint server arXiv.
