Polish scientists have discovered a new mechanism that cancer cells use to deceive the immune system. Cancer cells can send "malware" to the lymph nodes in order to block lymphocytes. Work on therapies using this knowledge is already in progress.
Polish and Lithuanian scientists studied 10,000 years old remains of a sunken forest in the area of Juodkrante near Klaipėda (Lithuania). When the trees, today sunken, formed a dense forest, the Ice Age was ending, and the Baltic Sea was forming as a result of the retreating ice sheet.
After the retreat of the glacier in Europe, the European bison`s diet changed. These animals moved to the forests from the more convenient open areas. The reason was not only a change in vegetation, but also human pressure. The aurochs did not adapt so well to these changes, researchers from Białowieża show.
A fractal is an object, a fragment of which looks similar to the whole when enlarged. Fractal structures have already been discovered in proteins, mountain ridges, signal from the stock exchange, sunspots and even Jackson Pollock`s paintings. Prof. Paweł Oświęcimka talks about what physicists are looking for in fractals.
Wines were produced in Poland a thousand years ago. The current climate is also conducive to wine production, which is why Polish scientists devote a lot of research to viticulture to make it more environmentally friendly and profitable, says Dr. Mariusz Maciejczak from the Warsaw University of Life Sciences (WULS-SGGW).
Extremely cooled atoms in the Bose-Einstein condensate behave like a cheerleading team. Now, for the first time in history, it has been possible to observe what happens when other atoms - like lost rugby players - bump into such a harmonious team. This is a historic achievement.
