Dr. Łukasz Witanowski from the Institute of Fluid-Flow Machinery of the Polish Academy of Sciences in Gdańsk proposes to use waste heat to produce cooling. The scientist is working on a system that will, for example, enable heating networks to generate cooling for air conditioning systems in the summer.
Scientists are now able to monitor individual neurons in a living human brain.
Students at the Warsaw University of Technology are working on the third nanosatellite PW-Sat3, whose task will be to test the proprietary drive that enables efficient deorbitation and manoeuvres in orbit. The launch is planned for autumn 2025. The work was delayed due to the pandemic and lack of stable financing.
Due to its physicochemical composition, 'Polish smog' is particularly dangerous for the circulatory system, increasing the risk of heart attack and stroke, says cardiologist Dr. Łukasz Kuźma. In his opinion, it is our 'new, infamous regional product'.
The lack of antibodies against the nucleocapsid protein of the SARS-CoV-2 virus doubled the risk of the so-called long COVID, an inter-university team of Polish scientists found. This discovery, which requires further confirmation, could potentially open new avenues for the prevention and treatment of this disorder.
Some animals have a well-developed self-awareness, but it is difficult for us to measure it using a simple mirror test. However, during research on horses, some of them behaved in a way that suggested that they recognised themselves in a mirror, says Dr. Tomasz Smoleń from the Department of Cognitive Science at the Jagiellonian University.
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.
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.
The properties of nanomaterials depend on how these structures vibrate, among other things. Scientists, including a Polish researcher, investigated the vibrations occurring in various types of carbon nanotubes.
When the molecules of a certain compound - tetracene - are arranged in the shape of a nano-snowflake, singlet fission occurs - a process that obtains as many as two electrons from one photon, Polish and Taiwanese scientists have shown. They hope that their research will help improve the efficiency of solar panels.
