Departments

core facilities department of biosciences

Welcome to the Faculty of Biological and Environmental Sciences!

Biocenter

The Faculty of Biological and Environmental Sciences with its neighbouring units forms the largest and most prominent scientific and educational unit for life sciences in Finland.

The significance of biological and environmental knowledge for the entire society is increasing. Applications of biosciences play significant role in health care and medical sciences. They also are extremely important in answering to environmental questions such as conservation of biodiversity and sustainable use of natural resources.

Actin dynamics change in dendritic spines as the spines develop (11.12. 2014)

In his doctoral dissertation, Mikko Koskinen developed a new approach to use fluorescence anisotropy to measure the level of actin bundling in dedritic spines. He also evaluated methods used to measure F-actin turnover in dendritic spines and the analysis of the data. He found out that the dynamics of F-actin change during the maturation of dendritic spines. The stable pool of F-actin increases in size and the turnover of the dynamic pool increases.

Formica ants

Formica ant larvae readily engage in egg cannibalism (22.10 2014)

Formica ant larvae are far from powerless. Eva Schultner's thesis identifies larvae as individuals with selfish interests. The larvae have the power to act in social conflict. Egg cannibalism may allow larvae to have influence on their own caste fate or size and for example affect overall colony fitness.

Micronuclei are used as a biomarker of human genotoxic effect. The recognition of the contents of the micronuclei is of utmost importance. The direct analysis of micronuclei in uncultured peripheral T lymphocytes, combined with centromeric FISH, may provide a new possibility for the assessment of chromosome breakage and numerical chromosome alterations occurring in vivo, says Ghita Falck in her doctoral dissertation.

Maria Jussila's doctoral dissertation shows that there is potential in the human tooth tissue to create new teeth. The inhibition mechanism for this is, however, not yet known. Tooth stem cells could in the future be used for example treating hereditary tooth diseases.

sequence

Sequence databases are growing fast – new methods needed for operating (18.8 2014)

More and more sequences are submitted to public databases, so faster and computationally lighter methods are needed for sequence retrieval. Patrik Koskinen presents in his doctoral thesis a computationally more efficient tool a hundred times faster than the most commonly used BLAST. He also introduces new methods for the calculation of information content value so that it is possible to separate informative and uninformative annotations.
