“Karelia: History in Stone” exhibition opened by the Institute of Geology KarRC RAS in the National Library of Karelia

The Institute of Geology KarRC RAS presented an exposition on the formation history of the subsoil of modern Karelia. The exhibition opening was timed to the Geologist's Day, celebrated on the first Sunday of April. Visitors will be guided through the genesis of Karelia's minerals, time-traveling billions and hundreds of millions of years back.
The exhibition “Karelia: History in Stone” is a follow-up to the previous exhibition launched by the Institute a year ago: “Seven Stones of Karelia that Everyone Should Know”.

- The previous exhibition received great feedback from both children and adults. We decided to do it again, having changed the theme. The new exhibition is about geological sites and destinations. It is a lead to the history of our region through Karelian destinations but from the perspective of the Earth's global evolution, - said Sergey Svetov, Director of the Institute of Geology KarRC RAS, explaining the concept.

The exhibition includes several display stands devoted to sites located in Karelia and revealing one of the chapters in the geological history of Karelia. Lava rock specimens are exhibited at the stand on the Vario paleovolcano at the Yalgora site, stromatolites found near Sundozero in the Kondopoga District show the booming of algae colonies in the ocean that used to cover the territory of modern Karelia, and stands dedicated to the Lososinka River channel show the traces left by the retreating glacier. Each of these destinations can be visited in person by going on a “weekend tour” or can even be reached by foot. For your convenience, the Institute of Geology has previously produced the “Geological Heritage of Karelia” guidebook.


Visitors in the exhibition

In addition to exploring the exhibition, the visitors could take part in master classes - learn more about minerals by examining them through a microscope, find out how to use a flashlight to locate unusual stones in the Karelian forest, and even see a fossilized body of the ancestor of modern squids. The master classes sparked great interest among the younger generation, while adults learned a lot from the lecture “Karelia: History in Stone” given by Sergey Svetov, Doctor of Geology and Mineralogy.

The master classes and lectures will be held at the National Library until April 27. The events are free to attend, with prior registration required for the master classes.

Karelian biologists ran successful trials of a technique for detecting fish infection with helminths based on traces of their DNA in water

Specialists of the Institute of Biology KarRC RAS were the first in the republic to test the method of environmental DNA analysis (eDNA) to detect a model fish parasite in an area impacted by trout farms. This is especially important in the context of a growing number of fish farms that use the practice of transporting stock (fry) from between water bodies, which creates a risk of new parasites appearing in lakes. Currently, fish have to be captured and examined to detect an infection, and for the output to be accurate the sample should be at least 15 fish. This may be problematic in the wild and costly in cage facilities. The eDNA diagnosis system can detect the presence of parasites directly in water samples.
