“Moiré structures can be formed as a result of interference, i.e. the overlapping of two layers of systems with a specific arrangement of points, lines or more complex systems - e.g. atoms in a crystal - rotated by a certain angle,” Professor Maciej Molas, from the UW’s Faculty of Physics says. The recent findings on moiré structures were published in the Science paper co-authored by Prof. Molas.
Renovation of the oldest mosque in Sudan
The Polish Centre of Mediterranean Archaeology (PCMA) UW is launching a new cultural heritage protection project “Baraka: Revitalization of the Oldest Preserved Mosque at Old Dongola” funded by the International alliance for the protection of heritage in conflict areas (ALIPH). The Old Dongola mosque is the oldest preserved mosque in the Republic of Sudan.
Archaeological research in Soba
Fieldwork in Soba, the former capital of the Kingdom of Alwa – today, a suburb of Khartoum – was paused for a mid-season break in mid-December. It was carried out by a team of specialists led by Dr Mariusz Drzewiecki from the Polish Centre of Mediterranean Archaeology, University of Warsaw. The excavations revealed the remains of a medieval garden. It is the first this kind of a discovery in Soba.
Life of conodonts
Conodonts were the first vertebrates that used to live in oceans nearly 500 milion years ago. Their teeth are the most often studied fossils. The research by UW doctoral candidate helps to reveal the life cycle and position occupied in the earliest foodwebs by these marine animals.
UW Physicists in ”Nature”
Scientists from the Faculty of Physics at the University of Warsaw led by Prof. Michał Tomza, together with the experimental group of Prof. Tobias Schaetz from the University of Freiburg, were the first to observe Feshbach resonances between single ion and ultracold atoms. The results of their work have been published in “Nature”. The article has also been highlighted on the journal’s cover.
4EU+ workshops on Open Science
What is Open Science? What happens with a scientific publication between the time of writing and the formatted paper published in an academic journal? What are the Creative Commons licenses? These aspects of Open Science will be explored during a series of online workshops organised by the universities of the 4EU+ Alliance, including the University of Warsaw. Registration is open now.
IDUB research infrastructure available to UW scientists
In spring 2021, 14 scientific groups obtained funding for the purchase of new research infrastructure from the “Excellence Initiative – Research University’ Programme” (IDUB). The first equipment has already been purchased – eight eye trackers requested by the Faculty of Psychology. They have been tested and are ready to use.
New article in “Nature Physics”
Researchers from the UW Faculty of Physics, University of Cambridge, Queen Mary University of London and University of Sofia have shown that slow cooling of a suspension of oil droplets with surfactant in water may lead to non-spherical shapes of the droplets, which can produce filamentous structures resembling bacterial flagella. The filaments induce motion of the droplets, and the process is ful
Discovery of oldest representation of a water wheel on a Roman mosaic from Apamea
Recent studies conducted by researchers from the Faculty of Archeology at the University of Warsaw contributed to a discovery of particular importance. On the famous figural mosaic, a huge hydraulic wheel was discerned. According to Prof. Marek T. Olszewski, it is currently known as the oldest representation of a noria.
An Earth-sized rogue planet discovered in the Milky Way
Our Galaxy may be teeming with rogue planets, gravitationally unbound to any star. An international team of scientists, led by Polish astronomers from the University of Warsaw, has announced the discovery of the smallest Earth-sized free-floating planet found to date.
The Denouement of the Enigma of the Roman Mosaic from the House of Aion in Paphos
After years of research conducted by Prof. Marek T. Olszewski from the UW Faculty of Archaeology, the iconographic program of the famous mosaic from the reception room of the Roman House of Aion in Paphos (Cyprus) has been resolved. The interpretation of the Polish researcher was accepted by scholars of Roman iconography as adequate and precise.
Counting on fingers – or beyond known oxidation states of chemical elements
Oxidation state usually takes the values from –4 up to +8, and even +9 in one case. Scientists from Centre of New Technologies have done advanced quatum-mechanical calculations and on this ground, they propose several simple molecules, where oxidation state is +9, and even could reach the value of +10.
