CERNIreland to become an Associate Member State of CERNToday, CERN Director-General Fabiola Gianotti and the Minister for Further and Higher Education, Research, Innovation and Science of Ireland, James Lawless, signed an agreement admitting Ireland as an Associate Member State of CERN. The Associate Membership will enter into force once CERN has been informed that Ireland has completed all the necessary accession and ratification processes. “We are extremely happy to welcome Ireland as an Associate Member State of CERN. Irish scientists have been involved in CERN’s programmes for more than two decades, covering fields as varied as experimental physics, theory, medical applications and computer science. This agreement enables us to enhance our collaboration, opening up a broad range of new and mutually beneficial opportunities in fundamental research, technological developments and innovation, and education and training activities,” said Fabiola Gianotti, CERN Director-General. “I am delighted to have signed this Associate Membership Agreement with CERN. This represents the culmination of significant work by the Government and CERN, building on the excellence of the Irish physics community. As an associate member of one of the world’s most significant research organisations, Ireland will have an opportunity to gain access to excellent research, innovation, collaboration and industry contracts. This long-term international commitment to our scientific community will demonstrate the Irish Government’s continued and expanding support of Ireland’s participation in leading global research collaborations,” said James Lawless, Irish Minister for Further and Higher Education, Research, Innovation and Science. Universities from Ireland are participating in the LHC experiments ATLAS, CMS, and LHCb, as well in experiments at the ISOLDE facility. A number of  theoretical physics groups in Ireland also collaborate with CERN. Furthermore, Ireland has a strong interest in computer science, medical physics and civil engineering, and several of its universities are working with CERN on various projects in these fields. Ireland submitted its formal application to Associate Membership in November 2023. Associate Member State status was granted to Ireland by the CERN Council on 28 March 2025. As an Associate Member State, Ireland will be entitled to appoint representatives to attend meetings of the CERN Council, of the Finance Committee and of the Scientific Policy Committee. Irish nationals will be eligible to apply for limited-duration staff positions and CERN’s graduate programmes. Irish companies will be able to bid for CERN contracts, increasing opportunities for industrial collaboration in advanced technologies.

The Universe is not symmetric Ideas like supersymmetry, grand unification, supergravity, and string theory all add additional symmetries, with intriguing consequences. The big problem? Our Universe isn't symmetric at all. bigthink.com/starts-with-... #physics #space #science #astro

The Universe is not symmetric

Big ThinkThe Universe is not symmetricThe laws of physics obey certain symmetries and defy others. It's theoretically tempting to add new ones, but reality doesn't agree.

Charged Drops Don’t Splash

When a droplet falls on a surface, it spreads itself horizontally into a thin lamella. Sometimes — depending on factors like viscosity, impact speed, and air pressure — that drop splashes, breaking up along its edge into myriad smaller droplets. But a new study finds that a small electrical charge is enough to suppress a drop’s splash, as seen below.

The drop’s electrical charge builds up along the drop’s surface, providing an attraction that acts somewhat like surface tension. As a result, charged drops don’t lift off the surface as much and they spread less overall; both factors inhibit splashing.* The effect could increase our control of droplets in ink jet printing, allowing for higher resolution printing. (Image and research credit: F. Yu et al.; via APS News)

*Note that this only works for non-conductive surfaces. If the surface is electrically conductive, the charge simply dissipates, allowing the splash to occur as normal.

Scientists have found evidence supporting Einstein’s prediction of “gravitational memory,” a permanent spacetime distortion caused by gravitational waves. New research suggests these wrinkles might be detectable using existing technology, revolutionizing our understanding of black hole collisions and Einstein’s general relativity.

Geneva, Switzerland - International physics laboratory CERN reports that a piece of a "groundbreaking experiment" at the Large Hadron Collider went missing yesterday, despite retina scanners at the doors which were installed after a popular novel suggested the idea. Scientists call for the vial containing an exotic substance called "antimatter" to be returned to the laboratory quickly before batteries run out, potentially causing a "cataclysmic event"
