In 1809, when Finland became a part of Russia after being under Swedish rule, Czar Alexander I described the event in very similar terms as President Vladimir Putin used in his speech on 18 March 2014 on the annexation of Crimea to Russia. "Both rulers strove to reassure their audience of their goodwill towards the well-regarded people in the area and appealed to both history and divine right. Alexander cited Napoleon and Putin the United States as the arrogant enemy," asserts Anneli...

Why Do Women And Men Differ In Height?
2014-02-07 12:41:01

University of Helsinki Researchers from the University of Helsinki analyzed thoroughly the commonly occurring genetic variation in chromosome X, one of the two sex-determining chromosomes, in almost 25,000 Northern European individuals with diverse health-related information available. The aim of the study was to find genetic factors that could explain individual differences in several traits, including BMI, height, blood pressure and lipid levels. In addition, the researchers also...

Our View On How Nature Is Structured Changed By DNA Barcodes
2014-01-21 14:11:58

University of Helsinki How you seek is what you find To understand how feeding interactions are structured, researchers from Finland and Canada chose to focus on one of the simplest food webs on Earth: the moths and butterflies of Northeast Greenland, as attacked by their specialist enemies, parasitic wasps and flies developing on their prey (called host), killing it in the process. "What we found in this system was mind-boggling", explains Helena Wirta, the lead author of the study....

Mini-microscope For Low-cost Diagnostics Created From Stripped Mobile Phone Camera
2013-12-06 12:34:40

University of Helsinki Microscopy, being relatively easy to perform at low cost, is the universal diagnostic method for detection of most globally important parasitic infections. Methods developed in well-equipped laboratories are, however, difficult to maintain at the basic levels of the health care system due to lack of adequately trained personnel and resources. Researchers at the Institute for Molecular Medicine Finland, FIMM, University of Helsinki and Karolinska Institutet,...

Smaller Islands Have Shorter Food Chains
2013-11-22 09:07:08

University of Helsinki That smaller islands will typically sustain fewer species than large ones is a widespread pattern in nature. Now a team of researchers shows that smaller area will mean not only fewer species, but also shorter food chains. This implies that plant and animal communities on small islands may work differently from those on large ones. Top predators the first to go Working across a set of 20 islands off the Finnish coast, a group of Finnish scientists found that a...

According to a Finnish study, women with eating disorders are less likely to have children than others in their age group. The discrepancy is the most apparent in anorexia sufferers. In this group, the number of pregnancies was less than half of that of the control group. The likelihood of abortion was more than double for bulimics than for others in the same age group. Meanwhile, the likelihood for miscarriage was more than triple for binge-eating disorder (BED) sufferers. For women who...

The eradication of poverty and advancement of sustainable development are key goals in the European Union, but they suffer from compromises and policy incoherence for development, says the first doctoral dissertation on the topic. Along with its member states, the EU is the biggest trade partner of the developing countries as well as provider of aid, but the internal dynamic of the Union is hampering its efforts to realize development policy goals. Problems are caused by both tensions...

Professor Hannes Lohi's research group at the University of Helsinki and Folkhälsan Research Center has identified a mutation in ITGA10 gene, causing chondrodysplasia in two dog breeds, the Norwegian Elkhound and the Karelian Bear Dog. The research revealed a new chondrodysplasia gene in dogs, and a candidate gene for human chondrodysplasias. The finding has implications on bone biology as well as canine health. A genetic test can now be used to identify mutation carriers in the two affected...

Eukaryotic cells are compartmentalized by membranes, whose shape and dynamics are precisely regulated to maintain their correct functions. Consequently, many cellular processes such as endocytosis, migration and morphogenesis rely on proteins that bind directly to membranes and sculpt them into desired shapes. BAR domain proteins are among the central membrane-sculpting proteins in all eukaryote cells. Studies by Pekka Lappalainen laboratory at Institute of Biotechnology, University of...

Emissions Of Greenhouse Gases From Cow Manure Modified By Beetles
2013-08-22 09:26:00

University of Helsinki Cattle contribute to global warming by burping and farting large amounts of greenhouse gases. Some of the same gases are also emitted from cow pats on pastures. But now researchers from the University of Helsinki have found that beetles living in cow pats may reduce emissions of the key greenhouse gas - methane. Agriculture is one of the biggest sources of the anthropogenic greenhouse gases responsible for global warming. Among these, cattle farming for meat and...
