A new genetic study carried out at the University of Helsinki and the University of Turku demonstrates that, at the end of the Iron Age, Finland was inhabited by separate and differing populations, all of them influencing the gene pool of modern Finns. The study is so far the most extensive investigation of the ancient DNA of people inhabiting the region of Finland.
Researchers have discovered new changes in blood samples which are associated with Alzheimer’s disease. A new international study examined Finnish twins. The study was conducted on disease-discordant twin pairs: one sibling who suffered from Alzheimer’s disease and one who was cognitively healthy. The researchers utilised the latest genome-wide methods to find out whether the twins’ blood samples had any disease-related differences in chemical marks, so-called epigenetic marks, which are sensitive to changes in environmental and lifestyle factors.
