Research is underway on a method of cryopreservation of African penguin sperm. The species is endangered so scientists believe that a sperm bank will help preserve a large gene pool, which will be helpful in the possible reconstruction of the species in the natural environment.
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.
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 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.
Releasing lynx saved from death into the natural environment is a good solution, it supports local populations of these predators, say experts after analysing the fate of 66 lynxes released after rehabilitation. The condition is professional rehabilitation of these wild animals.
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.
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.
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.
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.
Too much light at night not only interferes with astronomical observations and disrupts the behaviour of animals and plants, it can also threaten people, disrupting sleep, promoting obesity, depression and even cancer, said participants of the interdisciplinary seminar 'The Dark Side of Light - light pollution and its impact on our life'.
