Miscanthus biomass from contaminated soil crops useful in production of biofuels and biomaterials
Fuel and cellulose can be obtained from the giant miscanthus biomass; such cellulose can be used in building materials. Polish, German and British scientists examined the impact of growing this plant on soil quality, biomass production volume and the uptake of pollutants in soils contaminated with heavy metals.

Global warming and other environmental changes drive antibiotic resistance
Antibiotics are considered one of the greatest achievements of 20th century medicine. Their introduction reduced mortality due to bacterial infections and contributed to the extension of life expectancy. However, the consequence of their mass use in humans and animals is the emergence and spread of strains resistant to these drugs. According to estimates, in 2019, 4.95 million people around the world died due to antibiotic resistance, including nearly a million children.

Polish bats are not afraid of moonlight
Light at night makes bats an easier prey for predators, such as owls. This is such a big threat that in equatorial climates, bats limit their activity during the full moon. Meanwhile, researchers have now shown that bats in Poland are completely unconcerned by the Moon's glow during swarming. Where do these differences come from?

Bacteria that can degrade beta blockers in the environment – wanted!
Beta blockers are a group of drugs used mainly in circulatory diseases. Remains of these substances are not removed in sewage treatment plants and enter the environment, posing a threat to plants and animals. A biologist from the University of Silesia is looking for bacteria that can degrade them.

Flexible knots and links in particles under better control
Researchers from the University of Warsaw and the University of Wrocław have developed a method for constructing flexible molecular knots and links. Flexibility enables the formation of entangled regions in protein or nucleic acid molecules.

Where did wings come from? Early plumage may have been used by dinosaurs to rouse prey
Dinosaurs could have used the feathers on their forelimbs and tails to rouse and chase their prey, suggest Professor Piotr Jabłoński and a team from Korea. To confirm this hypothesis, the researchers built a robot - Robopteryx that scares insects - and examined the neurons of grasshoppers.
