Drop the drop

Porous materials are essential for many chemical processes, such as light harvesting, adsorption, catalysis, energy transfer and even new technologies for electronic materials. Therefore, many efforts have been made to control the porosity of any different manufactured materials.

    Awareness of how to behave in tunnels is low

    Today, tunnels are equipped with the latest security systems. The biggest problem is still people's behaviour, show the analyses conducted by a researcher from AGH University of Science and Technology in Kraków. 'Awareness of how to behave in tunnels is low', Dr. Natalia Schmidt-Polończyk says in an interview with PAP.

    Scientists develop Polish-language language models, possible Polish equivalents of GPT

    Scientists from the Gdańsk University of Technology and OPI have developed Polish language models called Qra. This is the first equivalent of Meta or Mistral AI's open tools on this scale. Qra understands content in Polish better and is better at creating coherent texts, the Gdańsk University of Technology reports.

    Beech trees synchronize on summer solstice

    Many plants, for example beeches, produce seeds irregularly, every few years. The question is how plants across the continent know whether a given year will produce seeds or not. Now researchers - led by a Polish scientist - show that it may depend on the weather around the summer solstice.

    Scientists develop reverse vending machines that will return funds to your account after hearing password

    Tests of a reverse vending machine developed in Poznań in cooperation with Łukasiewicz - Poznań Institute of Technology are scheduled to start in the summer. The machine is supposed to return the money to the account even if the person who recycles the bottle does not have a payment card. All they need to do is say a few words.

    Scientists from Warsaw University of Technology involved in work on new European battery

    Batteries consist of three basic components: two electrodes (cathode and anode) and the electrolyte connecting them. To improve the properties of the entire battery, scientists from around the world, including experts from the Warsaw University of Technology, are working on modifying the materials used to make these components.

    Researchers solve mystery of 'enigmatic' dinosaur Bagaraatan ostromi

    Bagaraatan ostromi was an enigmatic predatory dinosaur from the Late Cretaceous that had a complicated combination of features. New research conducted by palaeontologists, including researchers from the Polish Academy of Sciences, shows that the bones of two dinosaurs were mixed up in the skeleton, including bones from a juvenile tyrannosaurid.

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.
