The results of new research challenge the common view that the steppe bison was a strictly grazing animal, feeding mainly in the steppes, say scientists from the Mammal Research Institute PAS, who reconstructed the diet of the last representatives of the legendary megafauna.
Butterflies are associated with fragility, but they can fly several thousand kilometres using air currents, among other things. Their migrations are still poorly known, however, and they cannot be tracked as easily as birds, using rings or GPS transmitters, says botanist and ecologist Dr. Tomasz Suchan.
Type Ic supernovae carry within them a dramatic story of a relationship between a pair of stars. An international team of scientists led by Polish researchers has proven that for this type of cosmic explosion to occur, a not-so-peaceful - by human relationship standards - binary star system is needed.
In recent months, the Polish space sector has recorded spectacular successes, including the successful test of the Bursztyn rocket and the launch of the EagleEye satellite, believes Łukasz Wilczyński, president of the European Space Foundation. He adds that the challenge for Poland now is to determine the main directions of development of this sector.
Biologists from the University of Lodz are investigating whether plants can be used to remove 'forever chemicals' from the soil. These are non-biodegradable chemical compounds known as perfluoroalkyl substances (PFAS) that pose a serious threat to the environment and human health.
Scientists from Poland and Italy have identified the structure of the protein responsible for sensing cold. This protein plays a role in soothing pain, among other things, which is why in the future their findings may contribute to the development of new medical therapies for neuropathic pain and irritable bowel syndrome.
The legless lizard Pseudopus pannonicus, which lived in Poland between 15 and 2 million years ago, could have been over 2 m long.
Scientists from Wrocław University of Science and Technology offer a new perspective of the principles of operation of semiconductor lasers. The results of their important laser physics discovery have just been published in the journal Nature Photonics.
Palaeontologists discovered over 100 bones of terrestrial and marine animals from 240 million years ago each week during excavations at a site in Miedary (Silesia). Researchers are particularly pleased with several dozen well-preserved shark teeth.
EagleEye is a pioneering device - the first Polish satellite with such a large telescope, says Dr. Tomasz Barciński from the Space Research Center at the Polish Academy of Sciences. The largest, most advanced Polish satellite has been launched into orbit.
