Black grouse population in Poland nearly extinct, warns biologist
The black grouse population in Poland is on the verge of extinction, says Michał Adamowicz from the Faculty of Biology at the University of Warsaw. Over a few decades, it decreased from 30,000 to less than 300. The reasons include climate warming, the influx of alien species resulting mainly from human activity, and landscape changes for agricultural areas.

AllChemy HopCat algorithm cracks complex chemical rearrangements
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.

Tatra Mountains are no longer full of spruces - new, diverse forest grows in their place
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 died in the lower Oder
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.

Sundew to disarm antibiotic-resistant bacteria
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.
