The Estonian Genome Project is a national super-science project: gene samples from over 52,000 people were collected, which comprises about 5% of the population of Estonia. Now, 17 years after the project began, the Estonian Genome Center will offer personal feedback to people who donated their blood and information.

Through the Hardships
It was in 2001 when scientists from a small post-Soviet country came up with the ambitious plan to collect, record, and thoroughly decode the genetic information of Estonians. They hoped that the project would lead to scientific discoveries and help to create more precise medications. In 2007 the state became the project’s main financer and the Estonian Genome Center was united with the University of Tartu. Sample collecting began again, celebrities were hired to raise awareness about the project, and the topic of donating genetic information even appeared in the popular Estonian TV show “Õnne 13”.
The Estonian Genome Center got a new building with the monetary support from the European Union, new, state-of-the-art technology, and also lured back some of the scientists who had left Estonia. By the end of 2010, all the samples had been collected. What distinguishes this biobank from other biobanks in the world is that in Estonia the data collected did not involve only those who were ill, but it also offered a cross-sectional genetic view of the society.
Since early childhood, I have been travelling a lot. I have met people from different countries, cultures and backgrounds. It has shaped me a lot and made me dream about studying abroad. Eventually, my dream came true here, in Estonia.
Iryna as an International Student Ambassador
I arrived in Tartu in August 2014, when I started the Bachelor of Business Administration programme at the University of Tartu. I decided to study here for several reasons. Firstly, the University of Tartu is the best university in the Baltic Region, with a long and colourful history. Secondly, the programme is fully English-taught. Finally, Estonia is not really far from Belarus – my homeland.
For a while now, the team of Tartu Student Days has been organizing something amazing, something you have been waiting for many months now. A week-long (student) festival that fills our beloved Tartu with the most exciting events of the year.

But well.. what are those so-called “student days” anyway, huh? Student Days festival is aimed at the younger generation, to the ones who spend their days indoors studying or working. We, the volunteers (and also students!) want to make your time as a fellow student in Tartu as memorable as possible. The festival organizers spend their days generating new exciting and super cool events you might want to take part of to relax and have a break from the ordinary student life.
Since there are more than 150 different events during the festival, we have made you an example guide for an ultimate festival experience. Here are some of the most exciting events.
Physicists at the University of Tartu are working on an artificial nose based on graphene. In just a couple of years, all of us might have sensors in our cellphones, helping us to evaluate air pollution levels and choose routes with clearer air.
Just imagine the following situation: you are drinking your first coffee of the morning, and your coffee cup informs you that it would be wiser to work at home today. Or, if your presence at your workplace is really needed, then commute using a much longer path. The path is simultaneously projected on your kitchen wall. The warning was issued because of a prediction about bad air outside in the next few hours, and the fact that during the last month you were exposed to an unusually large amount of polluted air. Such a personal air pollution dosage could be determined if our portable smart devices included sensors for polluting gases and small particles in the air.

Raivo Jaaniso, the leader of the sensor technologies work group at the Institute of Physics at the University of Tartu, says that as a part of the major European Union project Graphene Flagship, he and his colleagues have set an aim to develop a graphene-based sensor chip of that nature. Their first goal is building a “nose” that could observe the quality of air. According to Jaaniso, a senior researcher of material sciences and applied physics, the really thin layer of graphene is like white paper that the scientist can write on: “Graphene is a carbon-based material with basically the thickness of one atom. One could imagine graphene by visualising a honeycomb with carbon atoms at each corner of the hexagons. Everybody has probably made some graphene by drawing lines with a pencil – it is what stays on the paper from a graphite core”.
