Marine ecologist: Creating seal reserves in Polish waters makes no sense

Seals do not constitute a permanent population off the Polish coast, they only 'pay visits' to rest on the shallows and take advantage of easy access to food, says marine ecologist, Professor Jan Marcin Węsławski. That is why, in his opinion, proposals to create seal reserves in Polish waters make no sense.

    'Polish hat' for any language model was created as part of PLLuM

    PLLuM language models were trained on Polish texts, tuned on Polish instructions and raised on the preferences of Polish users. Thanks to this, in addition to ready-made models, a 'Polish hat' has been created, which can be added to any language model, says AI expert Jan Kocoń, PhD.

    And yet it moves! DNA spins thanks to joint work of cellular motors

    Does DNA in the nucleus of a cell hang motionless, while RNA molecules that transcribe genes spin around it? It turns out that it is the other way around! It is DNA that is in motion. This is the only way to prevent tangles in the nucleus of a cell, scientists from a Polish-British team argue.

    NASK: In PLLuM language models we focus on safety and needs of Polish users

    We have made every effort to ensure that the Polish PLLuM language models are safe, adapted to the Polish language and 'trained' on legally obtained data, says Szymon Łukasik, PhD, from NASK, a centre involved in the work on the AI ​​models published in February.

    Polish researchers observe eye cells seeing something

    Photosensitive cells in the eye - cones and rods - change their sizes for a moment when light flashes on them. Polish researchers have just explained why. This tiny, fast pulsation of retinal cells can be seen live thanks to the Polish method of eye imaging.

    Why do trypanosomes need caps? Polish researchers explain how to use it to fight these parasites

    Scientists, including researchers from Poland, have explained the formation and functioning of an important structure, the so-called cap, which is part of the mRNA of trypanosomes. Their research may help create new strategies to fight these dangerous parasites of humans and cattle.

    Research confirms cannibalistic practices of prehistoric inhabitants of Maszycka Cave

    The latest analysis of over 60 bones from Maszycka Cave (Lesser Poland) shows that people living there 18 thousand years ago practiced cannibalism. This is indicated by traces on the preserved bones, including attempts to extract bone marrow, archaeologist Dariusz Bobak told PAP.

    Polish researchers develop prototype quantum computer infrastructure based on calcium ions

    The first prototype of a quantum computer infrastructure in Poland, based on calcium ions, is being developed at the Warsaw University of Technology. This project will help Poland to keep up with the development of quantum technologies, believes the representative of the MIKOK project, Zbigniew Wawrzyniak, PhD, from the Warsaw University of Technology.
