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.

    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.

    Polish scientists reinterpret petroglyphs of Toro Muerto

    The geometric patterns, lines and zigzags that accompany the images of dancers (danzantes) carved in the rocks of the Peruvian Toro Muerto are not snakes or lightning bolts, but a record of songs - suggest Polish scientists who analyse rock art from 2,000 years ago.

    Shaking nanotubes

    The properties of nanomaterials depend on how these structures vibrate, among other things. Scientists, including a Polish researcher, investigated the vibrations occurring in various types of carbon nanotubes.

    Molecular tailors sew nano-snowflakes for more efficient solar cells

    When the molecules of a certain compound - tetracene - are arranged in the shape of a nano-snowflake, singlet fission occurs - a process that obtains as many as two electrons from one photon, Polish and Taiwanese scientists have shown. They hope that their research will help improve the efficiency of solar panels.

    Warsaw astronomers discover Milky Way's longest-period classical Cepheid

    Astronomers from the Astronomical Observatory at the University of Warsaw have discovered a massive variable star, i.e. a classical Cepheid, with the longest pulsation period in our galaxy. According to researchers, it is not only the brightest, but also probably the youngest known classical Cepheid in the Milky Way. It is 22 million years old.

    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.

    Trematosaur remains from 250 million years ago are Poland’s first

    Trematosaurs, early Triassic amphibians that resembled today's crocodiles, lived also in the areas of today's Poland 250 million years ago, researchers from the Institute of Paleobiology of the Polish Academy of Sciences and the University of Warsaw have shown.

    Record stellar-mass black hole detected in the Milky Way

    Thanks to the Gaia Observatory, the European Southern Observatory's telescope and other ground-based instruments, scientists have tracked down a record-breaking black hole in our galaxy. Polish astronomers from the Astronomical Observatory of the University of Warsaw took part in the research.
