  • With climate change shrubs and trees expand northwards in the Subarctic

    2017.03.15

    Shrubs expand in the tundra in northern Scandinavia. And it is known that fixation of nitrogen from the air is in the tundra to a high degree performed by cyanobacteria associated with mosses. Also enhanced nitrogen fixation stimulates plant growth. New research shows that as taller shrubs expand into the tundra, nutrients in their leaf litter will either promote or reduce the nitrogen fixation, depending upon which shrub species that will dominate.  »

  • Breakthrough in live coral imaging

    2017.03.06

    Scientists at University of Copenhagen (Denmark), University of Technology Sydney (Australia), and Oregon Health University (USA) have used a well-known biomedical imaging technique called optical coherence tomography (OCT) to obtain fascinating insights to the structural organization and dynamics of reef-building corals. Their results have just been published in the multidisciplinary Journal of the Royal Society Interface. »

  • Scientists show how cells communicate

    2017.01.30

    Primary cilia are antenna-like structures that are present on the surface of most cells in the human body. The cilia are essential mediators of communication between the different cells in the body. If the cilia are defective, this communication is disrupted, and the cells are unable to appropriately regulate several important cellular processes, which ultimately can lead to severe diseases that may affect nearly every organ and tissue in the body, in the developing embryo as well as in the adult. »
