Scanning tunneling microscopy reveals origins of stable skyrmion lattices
Figure 1: The crystal structure of gadolinium ruthenium silicide, which can host a square lattice of swirling magnetic skyrmions (orange = gadolinium; green = ruthenium; blue = silicon). Modified from Ref. 1 and licensed under CC BY 4.0 © 2021 Y. Yasui et al.
RIKEN physicists have discovered how interactions between electrons can stabilize a repeating arrangement of swirling magnetic patterns known as skyrmions, which could help to further exploit these structures
1.
The spin of an electron causes it to behave like a miniature magnet. In a skyrmion, many of these spins are arranged in a swirling pattern that resembles a tiny tornado. Skyrmions are highly promising as a means of carrying information in a new generation of high-density, low-energy data-storage devices. ....

A new face mask that not only filters air but also prevents facial recognition. Blanc is purportedly a full-face modular mask that filters air through two high-efficiency, reusable, and replaceable HEPA filters that last up
to 14 days. It, uh, also has a one-way visor, adjustable straps, and 100+ magnetic panels and visors. So, in case the futuristic monochrome egg aesthetic just isn t cool enough, you could go Westie styles and snap on a leopard print panel.
Landmark divorce ruling
A Chinese court ordered a man to pay thousands of dollars to his ex-wife as compensation for housework performed during their five-year marriage. Her claim also said he had not participated in raising their child and  barely cared about or participated in any kind of domestic chores .

New Study Shows Peer Pressure Could Help Teens Make Safer Choices
Peer pressure, a powerful influence in the lives of students, has rather negative connotations in society, which includes the influence of peers on juvenile delinquency and the use of alcohol or cigarettes. According to a new study, affiliated with UNIST, observing social peers making safe choices may lead some teens to make healthy decisions than they would otherwise.
Professor Dongil Chung from the Department of Biomedical Engineering at UNIST, in collaboration with neuroscientists from Virginia Tech in the United States, has examined the influential power of safe teenagers among peers in a new neuroeconomics study. Using quantitative model-based analyses, they identified behavioral and neural evidence that observing others’ safe choices increases the subjective value and selection of safe options for substance-naïve relative to substance-exposed adolescents. ....
