A team of scientists from the Wrocław University of Environmental and Life Sciences proposes placing geodetic satellites in a 'butterfly' configuration, including satellites in retrograde orbit, where there are currently no objects orbiting the Earth.
The year 2023 ‘not only made the dreams of Polish space come true, it significantly exceeded them,’ says president of the Polish Space Agency Professor Grzegorz Wrochna.
Many species of hermit crabs have started using plastic covers instead of 'traditional' shells of animal origin. Scientists from Poznań and Warsaw describe this phenomenon in Science of the Total Environment. They emphasise that this is one of the signs of the environmental changes of the Anthropocene: plastic pollution on a massive scale.
A new technology for the synthesis of dimethyl ether has been developed at the Gdańsk University of Technology. It is an attractive, ecological alternative to diesel fuel.
The first species of turtles on Earth over time began to prefer the aquatic environment over the land one. Water helped them protect themselves from increasingly large, predatory dinosaurs. The analysis of the bones of these species, carried out by Polish scientists, helps understand the living environment of the oldest turtles.
Orbital Space, a company operating in the United Arab Emirates, will enable students of the AGH University of Science and Technology in Kraków to develop and test the Lunaris device. It is designed to study the interaction of selected materials and coatings with lunar dust - regolith. The invention is scheduled to fly into space in 2025.
There is a clear relationship between malocclusion and postural stability and balance, show researchers from three universities in Kraków. Therefore, when treating and diagnosing posture defects, one should approach the patient holistically instead of focusing only on the skeletal and muscular system.
Combined aerobic and resistance exercises offer the best results in supporting the therapy of patients with metabolic syndrome, show scientists from the Department of Anatomy at the University of Physical Education in Krakow.
‘Planets form wherever possible and they are very common. Although astronomers already know over 5,000 extrasolar planets, called exoplanets for short - we are still surprised by their diversity and the differences between most planetary systems and our parent system, the Solar System,’ says astronomer Dr. Grzegorz Nowak from the Nicolaus Copernicus University in Toruń.
Diodes that emit light regardless of the direction of current flow through the device - directly from alternating current (AC), and not only from direct current (DC) - have been developed by researchers from the Institute of High Pressure Physics of the Polish Academy of Sciences.
Scientists have re-examined the remains of a prehistoric marine reptile found in the 20th century in the village of Załęcze Wielkie (Łódź province). This distant relative of modern crocodiles was about four metres long and had a visible jaw injury, which it probably suffered in the first years of its life.
