1004 A simple chemical tweak could supercharge quantum computers

ScienceDaily
ScienceDaily · 02/25/2026 06:43 EDT

Quantum computers need special materials called topological superconductors—but they’ve been notoriously difficult to create. Researchers have now shown they can trigger this exotic state by subtly adjusting the mix of tellurium and selenium in ultra-thin films. That tiny chemical tweak changes how electrons interact, effectively turning a quantum phase “dial” until the ideal state appears. The result is a more practical path toward building stable, next-generation quantum devices.

Как я создал альтернативу трансформерам

В этой статье я хочу остановиться на разборе предложенной мной архитектуры декодера и тех вариантов, с которыми я сравниваю её в исследовании, но сделать это проще и интуитивнее, чем в самой работе. На мой взгляд, существующие объяснения архитектур декодеров часто подаются разрозненно. Каждый подход описывают отдельно, без общей опоры. А ведь всё можно свести к одному фундаменту, и тогда становятся гораздо заметнее как сильные стороны каждого решения, так и их... Read more

Расширяем OpenPLC с CAN bus

Эта статья является продолжением серии для демо-проекта на базе OpenPLC. В предыдущей части были рассмотрены программирование Raspberry Pi Pico W в режиме Modbus RTU/TCP Slave, управление реле через Ladder-диаграмму. Теперь пришло время добавить в схему CAN-шину. Что добавляется в этой части: узел Pico W получает модуль MCP2515 и подключается к CAN-шине. Для этого в OpenPLC Editor написан пользовательский функциональный блок, который работает поверх ардуино-библиотеки и предоставляет доступ к CAN-шине из... Read more

A bizarre, cyclops-like creature from nearly 600 million years ago may hold the key to how your eyes—and even your sleep cycle—evolved. Scientists have discovered that all vertebrates, including humans, trace their vision back to a single light-sensitive “median eye” perched atop a worm-like ancestor’s head. As this ancient animal shifted from a sedentary to a more active lifestyle, it lost and then reinvented its vision, eventually giving rise to... Read more

Scientists have discovered that moringa seeds can help pull microplastics out of water, rivaling standard chemical treatments. The plant-based extract causes plastic particles to clump together, making them easier to filter away. In some conditions, it even outperformed conventional chemicals. This low-cost, natural solution could be a game-changer for cleaner drinking water, especially in smaller communities. Read more

AI-powered personas are becoming so realistic that they can infiltrate online communities and subtly steer public opinion. Unlike traditional bots, they adapt, coordinate, and refine their messaging at a massive scale, creating a false sense of consensus. Early warning signs—like deepfakes and fake news networks—have already appeared in global elections. Researchers warn that the next election could be the true test of this technology’s power.

Researchers found that adding them to lipid nanoparticles can boost mRNA delivery up to 20-fold and push CRISPR editing efficiency close to 90%. The trick isn’t changing the drug—but helping cells take it in more easily. In early tests, the approach dramatically improved survival and treatment outcomes, pointing to a simple but game-changing... Read more

Cancer cells are known for their “glutamine addiction,” but many can escape this weakness by switching to alternative fuels. Researchers found that vitamin B7 acts like a metabolic “license,” enabling this escape route through a key enzyme. Without biotin, cancer cells lose that flexibility and stop growing. Mutations in a cancer-linked gene can make this vulnerability even stronger, offering a promising new target for therapy. Read more

A unique hybrid honeybee thriving in Southern California may hold a powerful clue to saving struggling bee populations. While U.S. beekeepers are losing massive numbers of colonies—largely due to destructive Varroa mites—a locally adapted mix of feral and diverse bee lineages is showing remarkable resilience. These bees aren’t immune, but they carry far fewer mites and are far less likely to require chemical treatments. Even more surprising, their resistance appears... Read more

Scientists at UC Riverside have found a clever new way to outsmart termites—by turning their own instincts against them. Using a natural pine scent called pinene, which smells like food to termites, researchers can lure the pests straight toward a targeted dose of insecticide hidden in wood. The result is dramatically higher kill rates—jumping from about 70% to over 95%—without the need for widespread toxic fumigation. Read more

A major discovery is reshaping how scientists think about catalysts. Researchers have, for the first time, captured oxygen atoms moving through the interior of a catalyst—not just along its surface. This reveals that the bulk material can actively participate in reactions, opening a new frontier in catalyst design. The finding could lead to smarter, more efficient systems by harnessing this hidden internal pathway. Read more
