Some horses recognise their reflections in mirrors, says expert

Some animals have a well-developed self-awareness, but it is difficult for us to measure it using a simple mirror test. However, during research on horses, some of them behaved in a way that suggested that they recognised themselves in a mirror, says Dr. Tomasz Smoleń from the Department of Cognitive Science at the Jagiellonian University.

    Researchers re-examine ancient crocodylomorph from Załęcze Wielkie

    Scientists have re-examined the remains of a prehistoric marine reptile found in the 20th century in the village of Załęcze Wielkie (Łódź province). This distant relative of modern crocodiles was about four metres long and had a visible jaw injury, which it probably suffered in the first years of its life.

    Canine 'Jack the Ripper' - last Eurasian lycaon from Polish lands

    We know lycaons from Africa, but about half a million years ago these predatory mammals also existed in the lands of today's Poland. Scientists who examined the remains of the last Eurasian lycaon from the Wieluń Upland call it the canine Jack the Ripper. It was able to knock down very large prey and eat its entire body.

    New 245-million-year-old reptile with very long neck discovered

    Trachelosaurus, a newly discovered reptile that lived about 245 million years ago, had a very long neck and a long spine. An international team of palaeontologists demonstrated this by going back to a description from a hundred years ago, when the bones were believed to come from several animals. Today it is known that they were the skeleton of one individual.

    Animal grazing increases plant species diversity and prevents fires

    Animal grazing contributes to increased biodiversity and ecosystem recovery after moderate fires, and reduces the risk of future fires. At the same time, large herbivorous mammals are more likely to feed in areas that have been burned, scientists from Poland and Sweden have shown.

    Bacteriophages have potential to save humanity, says biochemist

    Preparations composed of bacteriophages can be called self-producing and self-limiting drugs: they will multiply as long as they find bacteria. Without bacteria, they will disappear, says Professor Alicja Węgrzyn from the University of Gdańsk. In her opinion, bacteriophages have the potential to save humanity.

Polish researchers investigate causes of long COVID

The lack of antibodies against the nucleocapsid protein of the SARS-CoV-2 virus doubled the risk of the so-called long COVID, an inter-university team of Polish scientists found. This discovery, which requires further confirmation, could potentially open new avenues for the prevention and treatment of this disorder.
