The Polish Academy of Sciences asks prominent experts about the problem with bark beetle outbreaks in the Białowieża Primeval Forest. Should the protection of this ancient forest include felling and removing infected trees?
Prof. Anetta Undas from the Jagiellonian University Medical College discusses the sinister force of diseases, the commandments of scientific editing, and the patriotism of scientists.
We discuss waste, fuels, and air quality with Prof. Czesława Rosik-Dulewska from the PAS Institute of Environmental Engineering and the Department of Land Protection at the University of Opole.
We talk to Assoc. Prof. Paweł Gancarczyk from the PAS Institute of Art about how early music was perceived at the time when it was being composed, what modern musicologists regard as new discoveries and how our identities are shaped by sound.
Cartography is the study and practice of making maps. Although originally defined for Earth, the term is also a perfect description of the aims of the VIPERS team, whose members include Polish astronomers.
Extremes in the natural world, such as extreme weather phenomena, are rather unpleasant for people. In turn, the extremes that permeate society have far-reaching consequences. But where should extremes be encouraged?
Dr. Paulina Szafrańska from the PAS Mammal Research Institute in Białowieża explains why weasels range so greatly in size.
According to some studies, the phenomenon of professional burnout has reached epidemic proportions in today’s world. This applies in particular to those whose jobs involve saving lives: firefighters, police officers, and doctors who perform operations as well as members of the so-called social professions, which are based on close relations with people. This also includes therapists.
Not everything which comes from the sky is good for us. But if we’re worried about comets or meteorites crashing into Earth, we should also remember that much of what comes to us from the sky can be the source of momentous discoveries.
The Baltic is a unique brakish sea. Its moderate salinity is the result of the fresh river water input and non-periodic inflows of salty, oxygenated waters from the North Sea. However, the balance continually fluctuates. What impact does that have on the sea?
Ultra-high-energy gamma rays are stopped by the Earth’s atmosphere before they can reach the planet’s surface. However, our atmosphere could also become a tool for detecting photons with energies in the teraelectronvolt range. By using instruments registering Cherenkov radiation, astronomers conduct observations of sources emitting ultra-high-energy photons with ground-based telescopes.
Placoderms are the iconic prehistoric fish from the Devonian. Recent 3D scans have revealed their astonishing anatomical similarities with us humans.
The presence of women in science, methods of supporting them in pursuing careers in science, and the Polish Young Academy’s plans are discussed by Dr. Anna Ajduk of the University of Warsaw, who is chair of the Polish Young Academy, and its three deputy chairs – Assoc. Prof. Nicole Dołowy-Rybińska from the PAS Institute of Slavic Studies, Assoc. Prof. Monika Kędra from the PAS Institute of Oceanology, and Assoc. Prof. Monika Kwoka of the Silesian University of Technology.
When the temperature drops, rivers, lakes and seas become covered with ice, the water vapor in the atmosphere turns into snow crystals, and underground water turns into tiny ice lenses or veins. Glaciers and ice caps are formed in high mountains and in polar regions. All these large and small, visible and invisible forms of solid water on Earth together form what is known as the “cryosphere.”
When we mention mushrooms, our minds generally turn to grilled champignons for breakfast or gnomes lurking under toadstools. But the taxonomical kingdom to which they belong, the fungi, is actually vast and highly diverse: over one hundred thousand species have been described so far, and scientists estimate that the real number could be as much as fifty times greater. Some fungi have even taken a liking to aviation fuel!
We discuss meal colors, food-drying secrets, and changing consumer demands with Dr. Anna Michalska from the PAS Institute of Animal Reproduction and Food Research in Olsztyn.
To find out what affected sea level fluctuations in the past, researchers have to turn to the mountains. In ancient geological epochs, today’s Alps and Tatras were actually once on the ocean floor.
When something is very, very far to the right, it actually becomes closer to the left – especially to the very, very far left.
