…r knowledge, but remains the only known theoretical explanation of the number of quarks and leptons in the Standard Model. Several years ago, Prof. Krzysztof Meissner from the Faculty of Physics at the University of Warsaw and Prof. Hermann Nicolai from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute, AEI) went beyond N=8 supergravity and modified the original proposal, obtaining correct electric charges of the Standa…

…However, in real materials, atoms influence each other through short-range dipole-dipole interactions, which are typically neglected in calculations. Research by scientists from the University of Warsaw and Emory University in the USA has shown that dipole-dipole interactions, which are usually neglected, can amplify photons.   „Photons act as mediators, coupling each emitter with all the others inside the cavity,” says Dr João Pedro Mendonça, a…

…This discovery opens up new avenues for research into the social structure, beliefs, and regional contacts of the local population in the 1st millennium BCE.        …

…creasing number of pulses, and the receiver requires precise calibration and stabilization,” says Maciej Ogrodnik.   The new solution developed by researchers from the University of Warsaw avoids these problems. It uses all recorded photon detection events, resulting in significantly higher measurement efficiency. Although the method involves a slightly larger measurement error, this does not hinder the practical implementation of QKD – as confirm…

…UW Rector. At the beginning of the year, an emergency telephone number and a safety website were launched. Pursuant to the rector’s order of 30th June, the Office for Security Affairs was established. Sławomir Obliński is the director of the new unit. “The Office for Security Affairs was established to coordinate all activities related to the protection of the UW community in a consistent and professional manner. We are implementing solutions ada…

…naming of an asteroid, registered in the international catalogue under the number 599019 and previously designated 2009 QY36, as Jerzymadej. The event was organised as part of the celebrations of the 200th anniversary of the Astronomical Observatory of the University of Warsaw.   “On behalf of His Magnificence the Rector, I have the honour of presenting you with a letter of congratulations and expressions of appreciation from the entire Rector’s t…

…ntre for Medium-Range Weather Forecasts. The results confirmed the uniqueness of this year’s anomaly – for the first time in at least 85 years, such a marked weakening of the trade winds was recorded in the first months of the year, and thus a disturbance of the entire upwelling system.   Since 2022, Dr Chiliński has been collaborating with the Max Planck Institute for Chemistry, including the research team of s/y Eugen Seibold, as part of which m…

…status as the students of the University of Warsaw.   The first meeting in English is held on 26th September and the second in Polish on 30th September. Both events commence at 11 am on the UW campus at Krakowskie Przedmieście 26/28. The exact room number will be given to registered participants two days before the meetings.   To confirm your participation, please register using the appropriate form for your preferred session: meeting in English m…

…0% of migrants from Eastern Europe. Regional differences: While in the north (Central and Eastern Europe) the genetic shift was almost complete, in the south of the continent (the Balkans), migrants from Eastern Europe intermingled with the local population. This diversity of ancestry is also evident in contemporary populations in this region. Integration, not conquest: Genetic data indicate that migration was not limited to one gender: it appears…

…al Council for Nature Conservation in Warsaw for the 2025–2030 term. The Regional Council for Nature Conservation (PL: Regionalna Rada Ochrony Przyrody, RROP) is an advisory and consultative body to the regional director for environmental protection. The Council includes scientists, representatives of environmental organisations, the provincial council, and the State Forests.   The Council’s tasks include reviewing the work of and advising the reg…
