New invasive flatworm species discovered in the USA

The invasive flatworm species (Amaga pseudobama) discovered in the USA has already appeared in at least three states, the journal PeerJ reports. A scientist from the University of Szczecin is a member of the team that made the discovery.

    Butterflies can travel thousands of kilometres, but their migrations are still poorly known, says researcher

    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.

    Map shows areas of Warsaw that would be under water during flood

    Łomianki, Wawer and part of Wilanów - in the event of a major flood, these areas of Warsaw would suffer the most, according to an analysis by geomorphologists from the Warsaw University of Life Sciences. 'A much larger area of Warsaw than most experts believe is a flood area. This mainly concerns the right bank of the Vistula', says Dr. Grzegorz Wierzbicki.

    ‘We can make bacteria work for us’, says biochemist

    We can put bacteria to work to produce medicines, proteins and food, says Magdalena Janczewska from the Faculty of Chemical Engineering at the Warsaw University of Technology and co-founder of Science4Beauty, a company dealing with genetic modification of bacteria.

    By giving part of the city back to nature, we are doing its residents a favour, says researcher

    Large city parks with less mowing and leaves left on the ground for the winter, bee houses and more fruit trees in cities - these are some of the measures that support biodiversity in cities. Scientists argue that this also benefits residents.

    Autumn begins with mitoses. Cell division will not succeed without this unusual protein

    Mitosis, the process that leads to the creation of two identical daughter cells from one cell, is the foundation of life, growth and reproduction. It seemed that it was already a well-understood process. Meanwhile, another brick has been added to the knowledge about it.

    Carpathian lynxes and their ranges better understood

    Lynxes living in the Carpathians use vast areas and often move across national borders, scientists from a Czech-Slovak-Polish team have found. They have been studying these animals for a decade using modern telemetry collars.

    AI to help understand how to reprogram cells

    Dr. Andrzej Mizera from the Polish AI research and development centre, IDEAS NCBR, will conduct research on cell reprogramming using AI. An international team of scientists from Poland and Luxembourg will develop advanced computational methods that in the future may contribute to the treatment of Parkinson's disease.

    The warmer it gets, the greater the impact of herbivorous insects on forest ecosystems

    The higher the annual temperature, the greater the impact of herbivorous insects on the circulation of nutrients and carbon in deciduous forests, shows a global study conducted in 40 such natural environments. One of them was the Białowieża Forest.

    Biologists from University of Lodz investigate whether plants can help get rid of 'forever chemicals'

    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.
