Twisted graphene reveals a hidden superconductivity switch
Scientists have uncovered a surprising new way to control superconductivity — the mysterious phenomenon where electricity flows with zero energy loss. By pairing twisted layers of graphene with a synthetic diamond material, researchers were able to effectively switch superconductivity on and off by tweaking how electrons interact with their surroundings. Even more intriguing, the material behaved in ways that defied the rules of conventional superconductors, hinting at an entirely new kind of physics.
Superconductors by design: Argonne scientists rewrite the rules of discovery
Scientists at Argonne and Northwestern developed a new method to design and predict entire families of materials with the same chemical formula but different structures, enabling more efficient, targeted materials innovation and research.
Scientists just captured a mysterious quantum “dance” inside superconductors
In a breakthrough experiment, scientists directly imaged how particles pair up in a system that mimics superconductors. Instead of behaving independently, the pairs moved in a synchronized, dance-like pattern—something never predicted before. This suggests a major gap in the classic theory of superconductivity.
CERN Science Gateway celebrates its 1000th science show
CERN Science Gateway has reached another milestone: the delivery of its 1000th science show! Since opening its doors in October 2023, Science Gateway has welcomed nearly 900 000 visitors of all ages to explore the fundamental questions of the Universe. Among its most popular activities are the science shows – dynamic, interactive demonstrations led by CERN guides and tailored to a broad audience of different age levels, including school groups, families and the general public. Designed to make complex scientific concepts accessible and entertaining, these live shows combine spectacular experiments, multimedia elements and audience participation. From the physics of particle collisions to the properties of superconductivity, electromagnetism and cryogenics, the science shows translate the research carried out at CERN into engaging visual experiences. Visitors might see superconductors levitate, follow particles through different detector layers or discover the beauty in phase transitions. Each demonstration is carefully crafted to spark curiosity while maintaining scientific accuracy. Members of the CERN community are of course warmly invited to visit CERN Science Gateway with their family or friends and attend one of the science shows. To register, please visit this page, and don’t forget to check the programme for the coming days. Become a CERN guide and run your own super-cool science show (and more)! To become a CERN guide, you can join the introduction course held every 3–4 weeks, which will give you an overview of what being a CERN guide entails. From there, further courses are available depending on what type of guide you would like to be. Because, of course, CERN guides are needed everywhere at CERN. If you imagine yourself as a more ‘traditional’ guide, you should know that there are currently more than ten exciting visit points in CERN’s visits portfolio, such as the Antimatter Factory, the ALICE experiment (surface), the Alpha Magnetic Spectrometer (AMS) control room, the ATLAS experiment (surface), the CERN Control Centre (CCC), the Data Centre, the LHCb experiment (surface), the Synchrocyclotron (SC), the SM18 test facility and the newly inaugurated Linac2 visit point. Indeed, CERN’s Visits Service and Visual Impact and Exhibitions Section recently collaborated on redesigning the Linac2 visit tour, which has just reopened to the public after several months of renovation work. The new tour offers visitors and guides alike an enriched, more immersive experience, designed to highlight the history and scientific significance of this major facility. So, fancy becoming one of the insiders? Join the introduction course, check the guides website or contact guides.manager@cern.ch. And remember, becoming a guide can benefit you, too.
A hidden magnetic order could unlock superconductivity
Physicists have discovered that hidden magnetic order plays a key role in the pseudogap, a puzzling state of matter that appears just before certain materials become superconductors. Using an ultra-cold quantum simulator, the team found that even when magnetism seems disrupted, subtle and universal magnetic patterns persist beneath the surface. These patterns closely track the temperature at which the pseudogap forms, suggesting magnetism may help set the stage for superconductivity.

Superconductors, an opportunity for science and society
Superconductive technologies have long been central to particle physics, but they have also repeatedly moved beyond the laboratory, most notably with the emergence of magnetic resonance imaging scanners (MRI), demonstrating how breakthroughs in fundamental research can benefit society. Today, as global energy, climate and healthcare pressures grow, the conversation is shifting from “What can science give to society?” to “How can science and industry jointly develop technologies that benefit society while advancing research?” The event “Catalysing Impact – Superconductivity for Global Challenges” held at CERN in December was aimed precisely at answering this question. The workshop brought together leading researchers, industry representatives, investors and policymakers to explore how collaboration on superconducting technologies can advance particle physics while addressing some of the world’s most pressing societal challenges. The event sought to bridge fundamental research with real-world deployment and to accelerate collaborative pathways. Across keynotes, panels and round tables, participants examined both the current technological landscape and the opportunities ahead. Introducing the discussions, Frédérick Bordry, Chief Technology Officer of the Gauss Fusion company and former CERN Director for Accelerator and Technology, noted that “Superconductivity has become the silent engine of discovery science.” While the research community needs more capable and more resilient superconductors for the next generation of experiments, they also have significant potential for societal applications. Beyond their role in collider magnets, high-temperature superconductors (HTS) now promise lossless power transmission, compact fusion magnets, efficient renewable systems and new capabilities in healthcare, transport, computing and quantum technologies - all aligned with SDG-17’s emphasis on partnership-driven innovation. Participants also stressed that major hurdles remain. Global competition is accelerating, and Europe must act quickly to secure technological and economic leadership. Doing so will require coordinated investment and supportive policies, including stronger risk capital investment and mechanisms to bridge the gap between laboratory innovation and industrial deployment. The summit set in motion several concrete follow-up priorities, including aligning R&D roadmaps with societal goals and the UN Sustainable Development Goals; making it easier for public–private consortia to build demonstrators that serve both industry and research needs; and advancing investment pathways that better connect research institutions, governments and the private sector.
