Here we hear selected particle collisions turned into spatialised sound. This process creates sonic signatures of particles – such as the #HiggsBoson and the #Wboson – and of the “missing mass” in the CMS Experiment CERN detector, a key experimental feature of #DarkMatter. The work of artist Chris Henschke, this project suggests a different way to see CMS – a microphone listening to the fundamental particles of the #Universe Henschke works with digital and analogue media, sound and light, and experimental science, and has been developing novel ways of visualising and sonifying data from the CMS experiment since 2014.

What happens if you drop an anti-apple? In a paper published today in nature, the ALPHA collaboration at CERN’s Antimatter Factory shows that, within the precision of their experiment, atoms of antihydrogen – a positron orbiting an antiproton – fall to Earth in the same way as their matter equivalents. This result is a milestone in the study of the properties and behaviour of antimatter. Find out more:

Here we see, for the first time ever, the transport of unbonded protons across the CERN site, a big step towards portable #antimatter. CERN’s Antimatter Factory is the only place in the world where scientists can store and study antiprotons. But scientists at the BASE experiment hope to change this state of matter with an apparatus designed to store and transport antimatter. Last week, a team of BASE scientists and engineers took an important step towards this goal by transporting a cloud of 70 protons in a truck across the CERN site. Find out more about this first-time achievement:

Happy 70th anniversary CERN 🎉 #OnThisDay 70 years ago, twelve European countries came together to establish what has become the world’s largest #ParticlePhysics laboratory, home to the #LHC, and where the #HiggsBoson was discovered 12 years ago. In how many ways can you say #HappyBirthday? In this video, representing our 24 Member States, CERN people share their birthday wishes in their native language. #CERN70

Between the 1960s and the mid-1980s, dozens of women worked #AtCERN as “scanners”. Their job consisted in identifying the trajectories of the particles in the images taken inside the bubble chambers. “Scanning” took place around the clock. The work was done manually, using a pencil and a sheet of paper to note down the coordinates of where the interactions had taken place and a description of the interactions. The shifts only lasted four hours since scanners worked in complete darkness, which put a lot of strain on the eyes.

CERN pays tribute to Peter Higgs Peter Higgs’ scientific legacy will extend far beyond the scope of current discoveries. The Higgs boson is linked to some of the most intriguing and crucial outstanding questions in fundamental physics. This still quite mysterious particle therefore represents a uniquely promising pathway to physics beyond the Standard Model of particle physics.

Here we see one of the ProtoDUNE particle detectors being filled with liquid argon, a process that takes about two months. The liquid argon’s inert properties facilitate precise measurements, enhancing detection capabilities. ProtoDUNE is a prototype of the Deep Underground Neutrino Experiment (DUNE) housed at CERN’s Neutrino Platform. It will use the proton beam from the Super Proton Synchrotron and test and validate the technologies that will be applied to the #DUNEexperiment being built in the United States. Find out more about DUNE and how Fermilab and SanfordLab are involved:

What is the link between a rainbow in a box & the ATLAS detector at CERN? In this CERN-Solvay Education video, we build our own version of a detector for photons our eyes cannot see: photons in the infrared. At CERN, special instruments, called electromagnetic calorimeters (EMCALs), are needed to catch them in our detectors. Here we have a look at the ATLAS Experiment EMCAL.

What is dark matter? 🤔 We asked Erwan Robyn, a postdoctoral student, to tell us what is this mysterious matter that makes up 85% of our #Universe, and how is the Alpha Magnetic Spectrometer (AMS) experiment looking for #DarkMatter. Curious to know more? Are you currently in the Geneva (Switzerland) area? On 31 October at 19.30 CET, CERN organises an immersive evening that will take you on a journey from cosmology and #ParticlePhysics to neurosciences. Join us to celebrate #DarkMatterDay at CERN:

Here we see a sneak peek of a demonstration included in the science shows presented to #CERNScienceGateway visitors. In the video, we see a superconducting train advancing on tracks made of magnets. The train contains a disc made from a special ceramic called YBCO. By pouring liquid nitrogen on the disc, we cool it down to almost -196°C. At this temperature, the YBCO disc enters a superconducting state, changing its properties considerably. This phenomenon is called the flux-pinning effect – the disc gets “stuck” in the tracks’ magnetic field, causing the train to levitate and allowing it to move along the axis of the tracks. Join us at #CERNScienceGateway to learn more about how superconductors are used at CERN:
