Beauty is in the brain: AI reads brain data, generates personally attractive images

Researchers at the University of Helsinki and University of Copenhagen have succeeded in making an AI understand our subjective notions of what makes faces attractive. The device demonstrated this knowledge by its ability to create new portraits on its own that were tailored to be found personally attractive to individuals. The results can be utilised, for example, in modelling preferences and decision-making as well as potentially identifying unconscious attitudes.

A mechanism by which cells build 'mini-muscles' underneath their nucleus identified

Research groups at the University of Helsinki uncovered how motor protein myosin, which is responsible for contraction of skeletal muscles, functions also in non-muscle cells to build contractile structures at the inner face of the cell membrane. This is the first time when such 'mini-muscles', also known as stress fibers, have been seen to emerge spontaneously through myosin-driven reorganization of the pre-existing actin filament network in cells.

Micro-climate moulds and reshapes northern insect communities, herbivory and predation

Climate and changes in it have direct impacts on species of plant and animals - but climate may also shape more complex biological systems like food webs. Now a research group from the University of Helsinki has investigated how micro-climate shapes each level of the ecosystem, from species' abundances in predator communities to parasitism rates in key herbivores, and ultimately to damage suffered by plants. The results reveal how climate change may drastically reshape northern ecosystems.

Effects of organohalogen pollution are coded in gene expression profiles of Baltic salmon

Researchers of Ehime University and the University of Helsinki measured hepatic organohalogen (OHC) concentrations and gene expression profiles in Atlantic salmon collected from three areas in the Baltic Sea. The results showed that OHCs and gene expression profiles were individually grouped in three areas and the covariation of the two datasets provided by a multivariate method was significantly similar. This suggests that the gene expression profiles in salmon are affected by OHC contamination...

A computer predicts your thoughts, creating images based on them

Researchers at the University of Helsinki have developed a technique in which a computer models visual perception by monitoring human brain signals. In a way, it is as if the computer tries to imagine what a human is thinking about. As a result of this imagining, the computer is able to produce entirely new information, such as fictional images that were never before seen. The technique is based on a novel brain-computer interface.

Heated rivalries for pollinators among arctic plants

Insect pollination is as important to Arctic plants as it is to plants further south. When flowers abound, the plants have to compete for pollinators. Researchers at the University of Helsinki reveal that higher temperatures cause the flowering periods of different plant species to pile up in time. As a consequence, climate change may affect the competitive relationships of plants.
