Artificial intelligence has cracked some of the most complex chemical reactions - carbocation rearrangements - and predicted their products. This is thanks to the HopCat algorithm, an integral part of the AllChemy software created and developed by Professor Bartosz Grzybowski's group.
Not just spruces, but a diverse, mixed forest, including sycamore trees, beeches and rowan trees - this is how the forest landscape of the Tatra Mountains is changing, having been destroyed in recent years by hurricane mountain winds and spruce bark beetle outbreak. Professor Jerzy Szwagrzyk from the University of Agriculture in Kraków investigates this process.
Nearly 90 percent of mussels and aquatic snails and 3.3 million fish have died in the lower Oder. Across the entire affected stretch of the river, the estimated fish mortality was 1,650 tons, a 60 percent decline from pre-disaster levels. Researchers presented the summary of the effects of last year's Oder environmental disaster in the journal Science of the Total Environment.
Pliosaurs - a group of plesiosaurs - reached great sizes much earlier than previously thought, according to research by an international team of scientists including a researcher from the Polish Academy of Sciences. The discovery sheds new light on the course of the evolution of the huge marine predators.
The insectivorous sundew helps scientists destroy the 'armour' that protects bacteria from antibiotics. Even the most resistant bacteria on catheters or dressing materials have a much lower chance of growing and lose their antibiotic-resistant coating when treated with an extract from selected plants.
