The exhibition “Karelia. History in Stone” at the National Library of the Republic of Karelia will present a variety of exhibits: solidified lava, fragments of the ancient sea bed, hematite ore specimens, etc. Through these exhibits visitors will be able to connect to the history of the Earth and learn what Karelia looked like billions of years ago: how many volcanoes there were around the present-day Petrozavodsk, what lake was formed by meteorite impact, where the traces of an ancient sea beach in the Klyuchevaya district come from, and a lot more.
During April, visitors will be offered lectures and master classes: to examine minerals under a microscope, to learn how stones differ from each other, and to trace their path from a body of rock to a piece of interior design.

Scholarly geologists to give a series of lectures and master classes within the “Karelia. History in Stone” exhibition
The exhibition “Karelia. History in Stone” prepared by the Institute of Geology KarRC RAS is set to open at the National Library of the Republic of Karelia on April 6. It will introduce visitors to natural features found around Petrozavodsk: traces of volcanic eruptions, marine sediments and evidence of the origin of early life forms. During the month, scientists will be giving lectures and master classes at the library.

Scientists exploring for fungal strains capable of controlling ixodid tick numbers
Karelian scientists have conducted an experiment where taiga ticks (Ixodes persulcatus) were infected with various strains of entomopathogenic fungi – parasites that affect many groups of arthropods. The strain collected from Bolshoy Solovetsky Island in the White Sea proved to be the most effective: tick mortality in this treatment was 45% on the seventh day and rose to 95% on the eleventh day. The results can be used to develop biologics for controlling the numbers of the main vector of dangerous diseases.
