Scientific highlight of yesterday
Members of the ATLAS and CMS collaborations celebrated (with champagne!) that both collaborations have found a significant excess in data at the threshold where top and antitop quarks can be kinematically produced. At the EPS-HEP 2025 Top Quark Session, first CMS presented their excess they had found at the end of last year, followed from a talk by ATLAS confirming this significant excess independently. The probably most likely interpretation of the excess is due to quasi bound state effects beween the top and the antitop quark, so-called pseudoscalar toponium - such binding effects are known for all quark flavors but have never been observed for top quarks before.

Local scientific (fun)-fact
The Haute-Provence Observatory is an astronomical observatory 100 km north of Marseille. It was established in 1937 as a national facility for French astronomers. It is known as the place of the first definitive detection of an exoplanet in 1995: a giant planet in a four-day orbit around the star 51 Pegasi, located 50.6 light-years from Earth. At the time of the discovery Michel Mayor and Didier Queloz celebrated it with a bottle of sparkling white wine and a raspberry tart. They were later awarded with the 2019 Nobel Prize in Physics.
