It’s a big obstacle for long-distance internet and communications providers, yet a team of researchers think they’ve just solved this puzzle — and it could have massive implications for how you <a href="https://www.techradar.com/best/best-file-syncing-solution">send data</a> to and from your devices. </p><p>Researchers from Wits University in South Africa and the University of Bordeaux in France <a href="https://www.wits.ac.za/news/latest-news/research-news/2026/--2026-08/wits-researchers-use-lights-topology-to-beat-atmospheric-distortion.html" target="_blank">conducted an experiment</a> that involved shooting a beam of light through the air. The light was encoded with optical data, and when they recovered it at the destination site, they found it had arrived with over 98% fidelity, only dropping to 86% fidelity in “the most severe conditions tested.”</p><p>How did they do it? According to a paper the team published in the journal <a href="https://www.science.org/doi/10.1126/sciadv.aee2671" target="_blank">Science Advances</a>, the data was encoded into magnetic structures within light called skyrmions. These acted as a form of protective shielding that enabled the data to travel with the light, all without being altered by the surrounding environment. </p><p>It worked because the data was encoded into the light’s topological profile. Professor Andrew Forbes, Head of the Structured Light Lab in the Wits School of Physics, likened it to the comparison between a donut and a coffee mug: they both contain a round hole, and this factor remains constant if you reshape one into the other. In the same way, the light could be warped by heat and noise without garbling the data it was carrying.</p><h2 id="massive-potential">Massive potential</h2><figure class="van-image-figure inline-layout" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:4019px;"><p class="vanilla-image-block" style="padding-top:56.41%;"><img id="pfcXnmrQ8x9XonbevmnkY9" name="shutterstock_1723754989" alt="A concept image of a cargo spaceship in orbit of planet Earth on an expedition to resupply the ISS." src="https://cdn.mos.cms.futurecdn.net/pfcXnmrQ8x9XonbevmnkY9.jpg" mos="" align="middle" fullscreen="" width="4019" height="2267" attribution="" endorsement="" class="inline"></p></div></div><figcaption itemprop="caption description" class=" inline-layout"><span class="caption-text">The technology could be used to help improve satellite communications. </span><span class="credit" itemprop="copyrightHolder">(Image credit: Shutterstock)</span></figcaption></figure><p>This test wasn’t limited to short distances — the beam of light involved was transmitted over hundreds of meters, with plenty of heat, noise and wind present at the time. That means it therefore has a degree of applicability to real-world conditions. </p><p>Open air data transmissions have previously had to include constant real-time monitoring and correction of distortion, but if this latest research becomes usable on a wider basis, that might not be necessary for much longer. This technique could drastically reduce both the difficulty and cost involved in this kind of communication and has particular utility for <a href="https://www.techradar.com/pro/president-trump-wants-the-us-to-carry-out-more-than-1-000-space-launches-a-year-by-2030-and-speed-up-sending-robots-and-humans-to-mars">space missions</a>, where infrastructure like <a href="https://www.techradar.com/computing/memory/a-cure-for-the-memory-crisis-john-carmack-envisions-fiber-cables-replacing-ram-for-ai-usage-which-would-mean-a-better-future-for-us-all">fiber-optic cabling</a> is clearly not feasible. </p><p>High-speed <a href="https://www.techradar.com/pro/amazon-wants-to-launch-over-5-000-satellites-to-build-new-mobile-networks">satellite communications</a> and <a href="https://www.techradar.com/pro/the-worlds-first-diamond-powered-portable-quantum-computer-works-at-room-temperature-and-can-even-be-plugged-into-a-regular-wall-outlet">quantum computing</a> could also benefit from this technical advancement.
