A team of researchers led by Dr. Magdalena Winiarska from the Institute of Experimental and Clinical Medicine of the Polish Academy of Sciences has shown that ammonia accumulating in solid tumours suppresses the body’s immune response, aiding cancer growth and reducing the effectiveness of immunotherapy.
Palaeontologists from the University of Warsaw and the Polish Geological Institute – National Research Institute have described the first known Jurassic-era representative of the pycnodont fish group from Poland — a distant evolutionary relative of today’s parrotfish. The fossil dates back approximately 148 million years to the age of dinosaurs.
Poland is not threatened with desertification in the coming decades, but we to have the problem of drought. Droughts are more frequent, cover larger areas of the country and are more intense. Heavy rains do not solve the problem; they bring the risk of flooding, they do not end droughts, emphasises ecohydrologist Sebastian Szklarek, PhD.
The Solar Orbiter probe was the first instrument in history to conduct observations of the poles of our daytime star. This will help us better understand the Sun’s magnetic field, its activity cycles, and space weather. Experts from the Space Research Centre of the Polish Academy of Sciences (CBK PAN) participated in the construction of the probe.
Depending on the type of physical, strength or endurance exercise, our intestines will be inhabited by slightly different health-promoting bacteria, researchers have found. Understanding the mechanisms of response to training is a step towards personalised dietary and training strategies based on the microbiome profile.
Polish researchers have developed Vclust, a computer program that allows to compare millions of virus sequences in a matter of hours, and organize them according to the degree of similarity. Analysing huge genetic data sets with traditional methods would take years.
The longer the workers of a given species of ants live, the greater their tendency to rescue companions in need, Polish scientists have proven. Their results may be important for understanding social behaviours, especially those described as altruistic.
A project devoted to studying the causes of the mass extinction of freshwater mussels and their ability to adapt to climate change, taking into account, among other things, the impact of water temperature, pathogens and microbiome, is one of 11 projects from Poland to receive funding from the Swiss National Science Foundation.
Astrophotographer Marcin Rosadziński received the title of the 2025 Milky Way photographer of the year. His photograph of the Milky Way above a rocky peak in Madeira was rated the highest among over 6,000 photos submitted from all over the world.
In countries where social inequalities are the greatest, teenagers believe the most that they will achieve more than their parents. This is contrary to the so-called Great Gatsby curve known from economics, shows research in Science with the participation of a Polish researcher.
