Prognozuje się, że zasoby wody słodkiej dostępne dla ludzkości zmniejszą się o 30 proc. w ciągu najbliższych 20 lat. Jak odwrócić degradację zasobów wody i zrównoważyć zapotrzebowanie ludzi na wodę z potencjałem hydrosfery?
O tym, czym jest modelowanie i na czym polega modelowanie pracy mózgu, rozmawiamy z prof. Danielem Wójcikiem z Instytutu Biologii Doświadczalnej im. Marcelego Nenckiego PAN.

O poszukiwaniach najbardziej energetycznych promieni kosmicznych mówi dr hab. Piotr Homola z Instytutu Fizyki Jądrowej im. Henryka Niewodniczańskiego PAN w Krakowie.
Prof. Daniel Wójcik from the Nencki Institute of Experimental Biology explains the principles of brain modelling
Forecasts suggest that the freshwater resources available to our civilization will shrink by 30% in the coming two decades. How can we reverse the degradation of water resources and create a balance between the society’s demand for water and the capacity of the hydrosphere?
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.”
Managing human consumption has a major impact on the functioning of societies, and – even more importantly – on the condition of our planet. What does the future hold?
We talk to Prof. Piotr Homola from the Niewodniczański Institute of Nuclear Physics, Polish Academy of Sciences in Kraków, about his search for cosmic ray ensembles.
History and threats, research and future prospects: how much do we really know about the majestic horse-chestnut tree?
We talk to the pioneering climate-change researcher Prof. Hans Joachim Schellnhuber about the role of decency in fighting climate change, and why excellent climate science requires freedom and trust.
The paper presents experimental results of the lifetime of light induced excess carriers in the n-type silicon. The lifetimes of carriers of silicon crystals were analysed as a function of the intensity of light illuminating the sample. As a measurement method of the lifetime of carriers, the photoacoustic method in a transmission configuration with different surfaces was used. The dependence character was next analysed in the frame of the Shockley Reed Hall statistics in approximation of the light low intensity.
