Déjà vu - the false impression that 'this has happened before' - has many similarities with involuntary autobiographical memories, i.e. a situation when we suddenly remember a scene from our past, says psychologist Dr. Krystian Barzykowski from the Jagiellonian University.
Scientists from the Jagiellonian University have developed a new type of fertilizer for wide use in vascular plant cultivation. The fertilizer combines chemical compounds important for plants with a selected strain of endophytic yeast.
River deltas, leaf veins, lightning... in transport networks, simple laws of physics can surprisingly lead to cooperation between previously competing parts of the system, increasing its efficiency, shows research published in PNAS by Polish scientists.
One of the most important scientific achievements of the year - describing the connections in the entire brain of a fruit fly - was achieved not only thanks to laboratory research, but also thanks to the meticulous work of online game players.
Scientists have captured the high-resolution structures of one of the key proteins of photosynthesis in plants, recording a moment in the catalytic cycle. They found that water is forced out of the protein's active site through channels on its surface in a way that resembles the action of a syringe plunger.
Annihilation (mutual destruction of matter and antimatter) has long been used in PET scanners. Now an interdisciplinary team from Poland has developed a lightweight and cheap new-generation tomography scanner - J-PET, which measures the rate of this annihilation in various tissues. This new biomarker makes it possible to create brain maps with completely new information, e.g. about glioma.
'Inter-species gene exchange' and using genetic solutions developed by other species is a standard among animals, research by scientists from the Jagiellonian University shows.
Researchers from Kraków and foreign partners have studied the adaptive mechanisms of bacteria collected from the International Space Station (ISS). The findings indicate that microorganisms isolated from the interior of the ISS have adapted to life in space.
The wolf population in Europe is recovering. However, more frequent exposure to contact with humans is not enough for wolves to stop fearing us, according to preliminary analyses of research conducted by a team led by Dr. Dries Kuijper from the Mammal Research Institute of the Polish Academy of Sciences in Białowieża.
Three new species of buttercups have been identified near Darłowo in Western Pomerania by Dr. Adam T. Halamski from the Institute of Paleobiology of the Polish Academy of Sciences. The new species: the Amalasuntha buttercup, the Griffin buttercup and the Darłowo buttercup, were named to commemorate, among others, the queen of the Ostrogoths and the Pomeranian Griffin dynasty.
