903 A tiny twist creates giant magnetic skyrmions in 2D crystals

ScienceDaily
ScienceDaily 3 place · 03/02/2026 03:45 EDT

Twisting atomically thin magnetic layers does more than reshape their electronics—it can create giant, topological magnetic textures. In chromium triiodide, researchers observed skyrmion-like patterns stretching far beyond the expected moiré scale, reaching hundreds of nanometers. Even more surprising, their size doesn’t simply follow the twist pattern but peaks at a specific angle. This twist-controlled magnetism could pave the way for low-power spintronic devices built from geometry alone.

IT-инфраструктура клиники в 2026 году: Зоопарк систем или цельное решение?

Рынок медицинских услуг в России продолжает расти как на дрожжах. По данным аналитиков, в 2025-2026 годах мы наблюдаем устойчивый рост частной медицины на 12-15% ежегодно. Вслед за этим бумом неизбежно следует лавинообразный рост предложений IT-услуг. Кажется, что для каждой, даже самой узкой задачи, существует отдельное SaaS-решение: агрегаторы записи, ORM-системы для сбора отзывов, CRM для колл-центра, ERP для склада, МИС для врачей... Список можно продолжать бесконечно.Добавьте сюда ужесточение контроля. Read more

Как я взвесил черную дыру и отменил Темную материю с помощью Python (Анализ данных LIGO и SPARC)

Привет, Хабр! Меня зовут Павел, я независимый исследователь. Последние пару недель я находился в состоянии непрерывного потока, в результате которого с нуля написал 100-страничную монографию, вывел математический аппарат и написал Python-скрипты, доказывающие одну безумную, на первый взгляд, гипотезу. Весь этот путь от чистого листа до готовой публикации с DOI занял у меня ровно 15 дней.Суть гипотезы — Теории Вибрационно-Энергетического Резонансного Континуума (ТВЭРК) — состоит в том, чтобы отказаться от эй Read more

A new detection method called “Jerk” could dramatically improve how scientists forecast volcanic eruptions. By using a single broadband seismometer, the system can detect extremely subtle ground movements caused by magma pushing underground—often hours before an eruption begins. Tested for more than a decade at the Piton de la Fournaise volcano on La Réunion, the tool successfully predicted 92% of eruptions between 2014 and 2023, sometimes giving up to eight... Read more

A new AI framework called THOR is transforming how scientists calculate the behavior of atoms inside materials. Instead of relying on slow simulations that take weeks of supercomputer time, the system uses tensor network mathematics and machine-learning models to solve the problem directly. The approach can compute key thermodynamic properties hundreds of times faster while preserving accuracy. Researchers say this could accelerate discoveries in materials science, physics, and chemistry. Read more

Scientists at MIT have discovered that a little-known protein called intelectin-2 plays a powerful double role in defending the gut. The protein strengthens the mucus layer that lines the gastrointestinal tract while also trapping and disabling harmful bacteria that try to break through. By binding to sugars on both mucus molecules and bacterial surfaces, intelectin-2 forms a protective barrier and can even destroy microbes, including some that resist antibiotics. Read more

Scientists have discovered that cells can sense far beyond the surfaces they touch. While individual cancer cells can probe about 10 microns ahead by tugging on surrounding collagen fibers, clusters of normal epithelial cells can combine forces to detect layers as far as 100 microns away. This long-range “depth sensing” helps cells decide where to migrate. Understanding how it works could reveal new targets to stop cancer from spreading. Read more

Physicists at UC Santa Barbara have uncovered a new way to manipulate unusual magnetic states by exploiting “frustration” inside a crystal’s atomic structure. The team discovered a rare system where two different kinds of frustration—magnetic and electronic bond frustration—coexist and interact. By coupling these competing effects, researchers may be able to control exotic quantum states, potentially unlocking new ways to manipulate entangled spins for future quantum technologies. Read more

New research shows that sourdough fermentation does more than make bread rise—it transforms wheat fibers in unexpected ways. Scientists found that enzymes already present in wheat, activated by the sourdough’s acidic environment, break down key fibres called arabinoxylans. This process may influence the bread’s texture, digestibility, and flavor. Some microbes even create buttery or subtly sweet notes that give sourdough its distinctive taste. Read more
