• There Is a New, Third Category of Magnet and it Could Boost Computer Memory
    www.discovermagazine.com
    We tend to think of magnets as binary. Batteries have positive and negative ends. Compasses point north and south. And, until late last year, there were two kinds of magnetism: ferromagnetism and antiferromagnetism.Late in 2024, scientists discovered a third kind: altermagnetism. This class of magnetism which has some characteristics of the other two could greatly increase computer memory storage, and, in doing so, also save on both energy and rare earth materials. It could also boost the quest for superconductivity.A New Kind of MagnetismIt was only a theoretical concept in 2019, after researchers at Johannes Gutenberg University Mainz (JGU) in Germany came across a result that couldnt be explained by the two legacy types of magnetism. Experiments by the JGU group, with contributions from University of Nottingham researcher in England, and others, nailed down the third class as a legitimate form of magnetism in 2024. Subsequently more than 200 materials have been found to possess altermagnetic properties.Although the theory behind how it works and what it can do are somewhere one the continuum of esoteric and complicated (it touches on quantum mechanics and spintronics, among other concepts), the practical applications are so promising and profound that the journal Science named it the top physics find of 2024.The Different Kinds of MagnetismBut before we get too deep into the breakthrough, lets break down how all three forms of magnetism work and what are eachs strong and weak points:Ferromagnetism This is the old school understanding of magnetism that goes back at least as far as the ancient Greeks and that most of us learned about in elementary school. It works by aligning all magnetic movements in one direction. This form is great for holding computer information, but not so stable; a magnet could easily wipe out a hard drive, for instance.Antiferomagnetism As the prefix suggests, this form acts in the opposite way. It uses alternating checkerboard alignments. This uneven distribution of energy direction makes it a bad system for storage but, unlike its opposite, is extremely stable.Altermagnetism In terms of properties and mechanisms, it sits between the other two. Like antiferromagnetism, altermagnetic energy is distributed in a checkerboard pattern but with a twist. Each energy unit is literally twisted, rather than linear. The electrons all spin uniformly in that twisted direction."Altermagnets combine the advantages of ferromagnets and antiferromagnets, explained Hans-Joachim Elmers, JGU physicist and an author of the study, said in a press release.Their neighboring magnetic moments are always antiparallel to each other, as in antiferromagnets, so there is no macroscopic magnetic effect, but, at the same time, they exhibit a spin-polarized current just like ferromagnets, said Elmers. A Happy HybridProving this result was no easy task. It required an international team of scientists to perform, then combine experiments using multiple kinds of imaging techniques. Among them was Alfred Dal Din, a graduate student at the University of Nottingham. He considers himself fortunate to witness a major discovery while working on his Ph.D.To be amongst the first to see the effect and properties of this promising new class of magnetic materials during my Ph.D. has been an immensely rewarding and challenging privilege, Din said in a news release.

  • Newborn stars surround a planet-forming disk 450 million light years away
    www.popsci.com
    The James Webb Space Telescopes (JWST) picture of the month for February 2025 is showing off the power of planet formation. The space telescope recently honed in on protoplanetary disk HH30. It is about 450 million light years away from Earth in the dark cloud LDN 1551 in the Taurus Molecular Cloud.HH30 is considered a Herbig-Haro objectluminous regions that are surrounded by newborn stars, or protostars. These celestial objects form when jets of gas spewing from these newborn stars called stellar winds create shockwaves as they collide with gas and dust at high speeds. Protoplanetary disks like HH30 are where new planets can eventually form.According to the European Space Agency (ESA), HH 30 is of particular interest to astronomers. It is considered a standard model of an edge-on disk. Understanding what is going on in these disks can help astronomers study how dust grains in space drift and settle, eventually building entire planets.In the new image, an international team of astronomers used the JWST to investigate HH30 in greater detail. They combined JWSTs observations with those from the Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA).A close-in image of protoplanetary disc HH 30. Parts of the image are labelled Jet (above and below the disc), Conical Outflow, Possible Spiral, Dark Lane, Disk, and Tail. A scale marker in the bottom-left is labelled 300 au; this is a little wider than the disc itself, but less wide than the conical outflows above and below the disk. CREDIT: ESA/Webb, NASA & CSA, Tazaki et al. ESA/Webb, NASA & CSA, Tazaki etThe long-wavelength data from ALMA traces the location of dust grains that are only a few millimeters. The shorter-wavelength infrared data from JWST shows the distribution of even smaller dust grainsonly one millionth of a meter across or the size of a single bacterium. The large dust grains are concentrated towards the center of the disk and the small grains are more widespread.The observations were taken as part of the Webb GO program #2562. This project aims to understand how dust evolves in edge-on disks like HH30. When combined with radio-wavelength views from ALMA, these observations show that large dust grains must first migrate within the disk and then settle in a thin layer. The formation of a narrowyet denselayer of dust is an important stage during planet formation. This dense region is where dust grains can clump together to create pebbles and then eventually entire planets.[ Related: Enormous black hole napping after eating a ton of gas. ]In addition to the behavior of dust grains, the new images show several distinct structures that are all nested within one another. A high-velocity jet of gas emerges from the narrow central disk. That narrow jet is surrounded by a wider, cone-shaped outflow. A wide nebula that reflects light from the young star encloses this outflow.Together, this shows that HH 30 is a dynamic location and that massive jets and tiny dusts all play a role in building new planets.The post Newborn stars surround a planet-forming disk 450 million light years away appeared first on Popular Science.

  • FromSoftware Claims It Is Not Chasing a Trend with Elden Ring Nightreign
    cgshares.com
    FromSoftwareFromSoftware announced Elden Ring Nightreign, a standalone co-op spinoff with new gameplay elements set in the beloved universe, at The Game Awards 2024, and apparently, some players thought the studio was just trying to snatch a place in the popular multiplayer genre. However, the game director Junya Ishizaki, says it isnt true.The focus was condensing this experience down the RPG elements, the exploration, the character building, and leveling, he told PCGamer. We wanted that to feel like it was all coming together and culminating in a boss fight but in a more concentrated form.FromSoftware thought the game needed new mechanics and elements, a new sense of accomplishment that you wouldnt quite find with Elden Ring or our previous titles.In Nightreign, you will have to outlast 3 day-and-night cycles as one of the 8 characters with unique abilities and Ultimates, making split decisions about combat and exploration across changing maps to become strong enough to take down terrifying bosses at the end of each day, as explained by Pirat_Nation.There will be no armor, but youll get alternative skins, 3 Relic slots, and various weapons. While exploring, youll be faced with randomized events and enemies, and together, all of this makes Nightreign different from the original Elden Ring experience.Weve never really held the stance lets absolutely not do anything that other companies are doing or not follow any trends. So we didnt really see this as chasing a trend, but we saw these as interesting elements that could work well within our multiplayer-focused session-based gameplay.The game should be released for Xbox Series X|S, PlayStation 5, PlayStation 4, Xbox One, and PC in 2025.Meanwhile, you can start thinking of your strategy and join our80 Level Talent platformand ournew Discord server, follow us onInstagram,Twitter,LinkedIn,Telegram,TikTok, andThreads,where we share breakdowns, the latest news, awesome artworks, and more.Source link The post FromSoftware Claims It Is Not Chasing a Trend with Elden Ring Nightreign appeared first on CG SHARES.
