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. ....

Discovery offers a precise route to treat inflammation associated with neuropathic pain

Discovery offers a precise route to treat inflammation associated with neuropathic pain
One of the hallmarks of chronic pain is inflammation, and scientists at the UNC School of Medicine have discovered that anti-inflammatory cells called MRC1
+ macrophages are dysfunctional in an animal model of neuropathic pain. Returning these cells to their normal state could offer a route to treating debilitating pain caused by nerve damage or a malfunctioning nervous system.
The researchers, who published their work in
Neuron, found that stimulating the expression of an anti-inflammatory protein called CD163 reduced signs of neuroinflammation in the spinal cord of mice with neuropathic pain. ....

Study reveals how cells build 'mini-muscles' underneath their nucleus

Study reveals how cells build mini-muscles underneath their nucleus
Research groups at the University of Helsinki uncovered how motor protein myosin, which is responsible for contraction of skeletal muscles, functions also in non-muscle cells to build contractile structures at the inner face of the cell membrane.
This is the first time when such mini-muscles , also known as stress fibers, have been seen to emerge spontaneously through myosin-driven reorganization of the pre-existing actin filament network in cells. Defects in the assembly of these mini-muscles in cells lead to multiple disorders in humans, and in the most severe cases to cancer progression. ....

New method to enhance images of the SARS-CoV-2 virus

New method to enhance images of the SARS-CoV-2 virus
Researchers report a method of removing noise from high-resolution transmission electron microscopy images using probabilistic generative models.
Electron microscopy (EM) is a technique used to see viruses and their infection processes, allowing us to see how it binds to cells and spreads through the body. Transmission electron microscopy (TEM) can provide high-resolution images at the nanometer scale, but these low-light images generally have an abundance of noise. Images of viruses often appear flat or 2-dimensional.
Several noise reduction algorithms have helped improve image quality, allowing better interpretation of the data. For the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), EM images have also been used to reconstruct 3-dimensional (3D) images of the virus. ....
