AbstractThe consumption of organically produced foods is gaining increasing popularity. Simultaneously, the areas under organic control are expanding. Data obtained from the Sentinel-2 satellite are exceptionally suitable for agricultural monitoring, as the mission provides data every 2–3 days, allowing for the tracking of changes in crops.

The house mouse is the best-studied mammal species after humans, yet our understanding of its evolutionary history remains incomplete. Here, we focused on the colonisation of Europe by two subspecies and formation of a hybrid zone between them. We carried out a large-scale study of ~7000 mice sampled across an area embracing an ~900 km long portion of the zone, supplemented with cytochrome b and D-loop sequencing of ~1200 individuals collected worldwide.

Active galaxy nuclei (AGNs) are a class of objects that help us to understand the evolution of the Universe and test cosmology models. They are the most distant and luminous objects in the observable Universe. AGNs emit over the entire electromagnetic spectrum, and the intensity can exceed thousands of times the power of the host galaxy. This energetic process can be explained as accretion of matter on a supermassive black hole (Peterson 1997; Shields 1999).

AbstractA 4-amino-1,8-naphthalimide containing tetramethylpiperidine in N-position was synthesized. The prepared 1,8-naphthalimide was found to possess bright yellow-green fluorescence in a solid state, which could be switched-off in the presence of acid vapors and then switched-on after exposure on base vapors. The observed fluorescence quenching or enhancement, respectively, was more than 10-fold.
