Water and fire are thought of as extreme opposites. So what does water have in common with the great fireballs known as stars? Data from the Herschel Space Observatory indicate that young stars are where water molecules are formed.

The epistolary novel genre evolved from the art of letter writing, as well as from the 18th-century fashion of witty salon conversations centered around games, intrigue, understatement, quips and emotional manipulation. Does the Polish literature and history of the period reflect these conventions?

Active landslides are a significant problem in today’s world, especially in highly urbanized mountain regions. We are now able to monitor changes to the existing landform using increasingly sensitive technologies. Our joint team of scientists from Poland and China is working on implementing state-of-the-art technologies for monitoring landform deformation, which will be used to assess future threats.

Back in the 1960s, as a 21-year-old, he managed the first gigantic computer in Poland. Now the young people he gives win prizes in prestigious programming contests. We talk with Prof. Jan Madey about the history and future of computer science.

Despite a significant drop in mortality rates, cardiovascular diseases remain the number-one cause of death in Poland. Funding for novel procedures, such as transcatheter aortic valve implantation (TAVI), is nevertheless insufficient, compared to the scale of the problem in Poland and average implantation rates in Europe. That is one of the factors motivating the European Society of Cardiology’s and European Association for Percutaneous Cardiovascular Interventions “Valve for Life” Initiative.

Mammoths, wooly rhinos, and forest elephants died out long ago, but the massive bones they left behind enable us to imagine how impressive these prehistoric animals truly were.

Learning from textbooks? Certainly not for players of “geocaching” – i.e. several million people across the world who absorb geology-related knowledge by looking for places and objects according to clues left by others.


A whole zoo lives on our skin. In symbiosis, as long as our immune system is not overcome by a sudden crisis. naukaonline.pan.pl interviews the team of scientists who created a new detector of fungal infections – Prof. Włodzimierz Kutner, Dr. Maciej Cieplak, Marcin Dąbrowski, MSc. Eng., Dr. Krzysztof Noworyta, and Agnieszka Wojnarowicz, MSc. (PAS Institute of Physical Chemistry)


Prof. Leszek Kaczmarek (Nencki Institute of Experimental Biology of the PAS) and Prof. Andrzej Dziembowski (PAS Institute of Biochemistry and Biophysics) are among 9 research leaders to have won the first competition in TEAM program run by the Foundation for Polish Science, offering support to teams engaging in ground-breaking research.


Blazars are active galaxies centered around supermassive black holes. They generate strong electromagnetic radiation in a very wide spectrum – from visible light to radio, infrared, ultraviolet, X-ray, and gamma radiation. All those kinds of radiation are studied by Dr. Alicja Wierzcholska (PAS Institute of Nuclear Physics), winner of START competition organized by the Foundation for Polish Science.


New evidence has been found that reducing ambient temperature may contribute to body weight reduction. Staying in chilly environment alters intestinal bacterial flora in a way which might help fighting overweight. This is the conclusion of experiments on mice carried out by PAS Institute of Animal Reproduction and Food Research together with a Swedish research partner.
