Bacteriophages have potential to save humanity, says biochemist
Preparations composed of bacteriophages can be called self-producing and self-limiting drugs: they will multiply as long as they find bacteria. Without bacteria, they will disappear, says Professor Alicja Węgrzyn from the University of Gdańsk. In her opinion, bacteriophages have the potential to save humanity.

Scientists probe impact of environmental pollution on colouration of 25 bird species
The impact of a polluted environment on the colour of a birds’ feathers and bodies varies depending on the type of colour. Scientists are trying to determine how serious this impact is, but they still lack some data, for example, on what the importance of the presence of pharmaceuticals in the environment is.

Research into synthetic riboswitches may lead to new antibacterial therapies
Scientists from the University of Warsaw, in collaboration with colleagues from Japan, are conducting research on riboswitches - RNA segments that control the production of proteins in bacteria. In the future, their research may result in new strategies for combating antibiotic resistance in microorganisms.

Wrocław scientists looking to create ‘penguin sperm bank’ to preserve endangered species
Research is underway on a method of cryopreservation of African penguin sperm. The species is endangered so scientists believe that a sperm bank will help preserve a large gene pool, which will be helpful in the possible reconstruction of the species in the natural environment.
