Researchers create a never-before-seen molecule and prove its exotic nature with quantum computing - Phys.org

Every day, our site receives millions of automated requests consuming terabytes of bandwidth — most of them from content scrapers that provide no value to real users. To keep the site fast and reliable, we sometimes show a quick security check. Over the past few years, the nature of web traffic has changed dramatically. The majority of traffic hitting many websites today is no longer human — it is automated. Unfortunately, these are not helpful bots (like search engine crawlers), but large-scale content scrapers that copy data and consume resources without providing value to our users. Today’s bots are designed to look like real people. Modern scrapers: Because of this, traditional bot detection techniques (like basic rate limits or simple bot filters) can’t reliably distinguish between humans and automation. Even though you never see these bots, they have a real impact: Without protection, the cost of running the service would increase dramatically — and directly impact our ability to keep it running and responsive for real users. We use Turnstile (by Cloudflare) selectively, not for everyone. This allows most visitors to browse normally without interruption while still protecting the platform. So if you do see it, it’s because the system just wants to quickly confirm you’re human. We understand that any extra step can feel inconvenient. However, without this protection our operational costs would skyrocket, which would directly affect the stability and availability of the site. This is not something we added lightly — it’s a measure we were forced to adopt to keep the service sustainable. If you are using a modern, up-to-date browser, the check: Turnstile is not used for tracking or profiling you. It simply verifies that: It does not collect personal data or allow us to identify you. These protections help ensure that real people — not automated scrapers — get fast, reliable access to the site. We truly appreciate your patience and support as we work to keep the service sustainable and available to everyone. If you have any questions or encounter problems, please use our contact page.
