Shifting from giant accelerators 26 km (16 miles) across to brain surgery theaters, a particle detector first developed by physicists at CERN is being used by scientists in Germany to treat brain tumors with greater precision and safety.Destroying head and neck tumors is relatively simple. You dose them with the right chemicals or blast them with powerful enough radiation, and job done. The problem is figuring out how to kill the cancer cells without killing the patient.One effective way of treating such tumors is by…

How to implement PSOPhoto by James Wainscoat on UnsplashBefore talking about swarms and particles, let’s briefly discuss optimization itself. Basically, optimization is the process of finding the minima or maxima of some function. For instance, when you need to get to your office ASAP and think about which way is the fastest, you’re optimizing your route (in this case it’s a function). In math, there are literally hundreds of ways of optimization, and among them a sub-group called nature-inspired exists.Nature-inspired…

Using off-the-shelf industrial parts, a team of researchers from the public and private sectors has created a prototype of a small particle accelerator that could have a big impact bringing the technology forward for commercial applications.If you're familiar with particle accelerators, you know that they're big. And expensive. And they take a long time to build. At the core of CERN's Large Hadron Collider, for example, is a 27-kilometer-long (17 miles) magnet-studded ring. That facility took about 10 years to bring…

A team led by former Twitter engineers is rethinking how AI can be used to help people process news and information. Particle.news, which entered into private beta over the weekend, is a new startup offering a personalized, “multi-perspective” news reading experience that not only leverages AI to summarize the news, but also aims to do so in a way that fairly compensates authors and publishers — or so is the claim. While Particle hasn’t yet shared its business model, it arrives at a time when there’s a growing…

Not everyone is fully on board. Some theorists worry that the approach will only yield more false alarms from the collider—more tentative blips in the data like “two-sigma bumps,” so named for their low level of statistical certainty. These are generally flukes that eventually disappear with more data and analysis. Koren is concerned that this will be even more the case with such an open-ended technique: “It seems they want to have a machine that finds more two-sigma bumps at the LHC.”  Nachman told me that he received a…

You’re probably excited for DUNE—no, not that one. I’m talking about the Deep Underground Neutrino Experiment (DUNE), a mile below Lead, South Dakota, where three massive caverns have been excavated for the world’s latest search for the enigmatic particles.Alex Winter on Innovative Horror Movies About 100 trillion neutrinos pass through your body every second, according to the IceCube Neutrino Observatory. They are the lightest particles that have mass, and as far as we know are fundamental—they are not made up of any…

While stormwater runoff pollutants in general aren't great for aquatic animals, chemicals from tire particles are particularly harmful to salmon. A recent study now shows that permeable pavements could keep most of those toxins from ever reaching the fish.Ordinarily, when rainwater runs along city streets, it carries pollutants from those streets down the storm drains and out into the local waterways. One proposed method of addressing that problem involves replacing existing road surfaces – or building new ones – with…

By U.S. Department of Energy January 13, 2024Scientists from the BEST experiment have detected a shortfall in germanium 71 production from neutrino interactions, suggesting the possible existence of the sterile neutrino. This anomaly, consistent with previous findings, challenges existing theories and may indicate new physics or unresolved experimental errors. Credit: SciTechDaily.comThe Baksan Experiment on Sterile Transitions (BEST) finds evidence of the sterile neutrino, a hypothetical particle that interacts only via…

Illustration of two types of long-lived particles decaying into a pair of muons, showing how the signals of the muons can be traced back to the long-lived particle decay point using data from the tracker and muon detectors. Credit: CMS/CERN This search for exotic long-lived particles looks at the possibility of “dark photon” production, which would occur when a Higgs boson decays into muons displaced in the detector.The CMS experiment has presented its first search for new physics using data from Run 3 of the Large Hadron…
