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'.
Scientists are investigating whether gravity storage can be used to collect energy from renewable sources. Researchers working on the project will build a pilot small-scale energy storage facility to demonstrate and verify the viability of the proposed technology.
Local history enthusiasts have discovered four Roman-era brooches, a ring and fragments of decorations in the Borki forest district in Masuria. They handed over the finds to the monument protection services.
Fuel and cellulose can be obtained from the giant miscanthus biomass; such cellulose can be used in building materials. Polish, German and British scientists examined the impact of growing this plant on soil quality, biomass production volume and the uptake of pollutants in soils contaminated with heavy metals.
Antibiotics are considered one of the greatest achievements of 20th century medicine. Their introduction reduced mortality due to bacterial infections and contributed to the extension of life expectancy. However, the consequence of their mass use in humans and animals is the emergence and spread of strains resistant to these drugs. According to estimates, in 2019, 4.95 million people around the world died due to antibiotic resistance, including nearly a million children.
A team of researchers from Poland and Norway has developed a questionnaire to detect and measure the level of emotions related to climate change, the Nencki Institute of the Polish Academy of Sciences reports.
Electrical brain signals in patients with multiple sclerosis, a disease mainly associated with the slowing-down of information processing and a lack of motor coordination, show traces of multifractality, scientists from four Polish research institutions have found.
