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.

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.

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.

Why cuckoo calls sometimes sound differently and what it means
Cuckoos can change the structure of their voice and song due to various factors. New experiments show that the modified version of the cuckoo call draws less attention from other cuckoos than the classic 'cuckoo'. This may mean that males with impaired song are at a disadvantage when competing for females and territory.

Polish researchers observe eye cells seeing something
Photosensitive cells in the eye - cones and rods - change their sizes for a moment when light flashes on them. Polish researchers have just explained why. This tiny, fast pulsation of retinal cells can be seen live thanks to the Polish method of eye imaging.

Why do trypanosomes need caps? Polish researchers explain how to use it to fight these parasites
Scientists, including researchers from Poland, have explained the formation and functioning of an important structure, the so-called cap, which is part of the mRNA of trypanosomes. Their research may help create new strategies to fight these dangerous parasites of humans and cattle.

Experts: Cats belong at home, otherwise they threaten wild species, including protected ones
Cats are domestic animals and should not live in the wild or be let out of the house freely, experts say. They warn that in Poland, over 0.6 billion mammals and almost 150 million birds fall prey to feral and outdoor cats every year; many of them are protected species.
