The ultra-long-period Cepheid
23-04-2024…Milky Way. The newly discovered classical Cepheid in the Galaxy, named OGLE-GD-CEP-1884, can be categorised as the first ultra-long-period Cepheid in the Milky Way. The period of 78.14 days is nearly ten days longer than that of the previous record-holding Cepheid, S Vulpeculae. This star is present in the ASAS-SN and Gaia DR3 catalogs of variable stars, yet it has been classified as a long-period variable. Based on more than ten years of the phot…

On the habits of mammals during the pandemic
19-03-2024…ipation of Kinga Stępniak and Dr Tom A. Diserens (received his doctoral title in 2023) from the University of Warsaw analysed material collected through trap-cameras. They recorded 163 mammal species living in twenty-one countries. The researchers compared data on the animals’ habits before the pandemic and during the lockdowns to see what impact changes in human activity had on animal behaviour. The authors found that mammal activity in more de…

Mediaeval fabrics from Dongola
24-01-2024…ng research in Africa often face lack of written sources since the tradition of oral transmission of information prevailed there. The daily life of the inhabitants of Old Dongola – including local textile production and dyeing – can be learned by studying the material culture of the community,” Dr Magdalena Woźniak of the Polish Centre for Mediterranean Archaeology (CAŚ) at the University of Warsaw, says. An interdisciplinary team from the Unive…

Prehistoric finds by UW biologists
05-12-2023…We have discovered, among others, the remains of the crocodile-like Mastodonsaurus, the fish-eating yet unnamed armoured reptile and the aquatic predator Jaxtasuchus,” Dr Mateusz Tałanda says. Among the most interesting specimens are numerous bones of Tanystropheus, a reptile that reached six metres in length. Due to the recent discoveries, Miedary has become the world’s richest source of remains of this species. What is also surprising is the…

Chimpanzee ground versus tree nests decay
31-07-2023…d using the tree species Omusetera (Maerua sp.), had not disappeared after one year. In a subset of 15 ground and 19 tree nests, terrestrial nests reached a more decayed age category more rapidly than arboreal nests. This difference may be related to the plant species used in nest construction. In areas in which chimpanzees nest frequently on the ground, an update is proposed to the formula commonly used to estimate chimpanzee densities: the nes…
