Precipitation to glass: It takes water days to thousands of years to make this 'journey'
From several days to even hundreds and thousands of years - this is how long it takes for water precipitation that fell on the Earth's surface to reach the groundwater level, where over 70 percent of drinking water in Poland comes from, says hydrogeologist Małgorzata Woźnicka, PhD.

Ornithologist: Spring mating of birds is a true spectacle of nature
The mating habits of birds can be spectacular. Some species use singing, others dance and do aerial acrobatics, others still show their strength. There are also females who choose a male based on the appearance of the nesting site he occupies, says ornithologist Grzegorz Neubauer, PhD, a professor at the Museum and Institute of Zoology of the Polish Academy of Sciences.

Microalgae from peatlands are our allies in fight against global warming
There is hope that microalgae inhabiting peatlands will absorb more and more carbon dioxide as the temperature increases. They may not stop climate change, but they will be our allies in the fight against global warming. So far, research has ignored the role of this group of organisms in climate analyses.

Fish and large aquatic invertebrates contribute to degradation of microplastics
The foraging activity of fish and large aquatic invertebrates, such as crayfish, contributes to the mechanical fragmentation of microplastics, reducing their average size and accelerating their degradation, scientists from the University of Warsaw, Warsaw University of Life Sciences, AGH UST, the University of Rzeszów and an Indian university have demonstrated.

Study: With more concrete in city space, fewer chicks survive spring
If half of the green space in a city is covered with concrete, the number of young birds flying out of the nesting boxes in that area will be halved, scientists from the University of Warsaw have shown. The results of their study also provide precise data that can be used by decision-makers.

Marine ecologist: Creating seal reserves in Polish waters makes no sense
Seals do not constitute a permanent population off the Polish coast, they only 'pay visits' to rest on the shallows and take advantage of easy access to food, says marine ecologist, Professor Jan Marcin Węsławski. That is why, in his opinion, proposals to create seal reserves in Polish waters make no sense.

Saving Poland's oldest 'vegetarian piranha', huge aquarium needed
A rescue operation for a 40-year-old 'vegetarian piranha' is underway at the Sea Fishing Museum in Świnoujście. After the huge aquarium cracked, the fish was moved to a pallet tank provided by firefighters. A new permanent home for it will be ready in 2 weeks or so.

Declining genetic diversity threatens species crucial for human survival, scientists warn
A decline in genetic diversity concerns two thirds of species of organisms, warns an international team of scientists, which also includes Polish researchers. This means that in the face of significant climate changes, many common species crucial for human survival may not become extinct.

Study: Wolf population in Europe continues to grow
A large predatory species can coexist with humans, scientists have announced, summarising the condition of the wolf population in Europe. According to their estimates, there are over 21.5 thousand wolves living on our continent, while a decade ago there were about 12 thousand. This is the result of conservation programs.

And yet it moves! DNA spins thanks to joint work of cellular motors
Does DNA in the nucleus of a cell hang motionless, while RNA molecules that transcribe genes spin around it? It turns out that it is the other way around! It is DNA that is in motion. This is the only way to prevent tangles in the nucleus of a cell, scientists from a Polish-British team argue.
