A small protein with many applications

Researchers from the Department of Molecular Biology and Genetics and from the Department of Biomedicine at Aarhus University have collaboratively developed and described a llama-antibody that might have significant impact for future diagnostics and treatment of, e.g., kidney diseases.

Schematic diagram of Arctic-specific conditions that affect microbial degradation of oil spills: A) Sea ice and icebergs hamper wind/wave-induced mixing in the upper water column and cause a thicker oil slick, which, in combination with low temperature, reduces evaporation, dispersion and dissolution. All these effect result in larger oil droplets, which microbes cannot degrade. B) Most oil compounds are not soluble in water. Therefore, the bacteria form a biofilm on the oil droplets in order to be able to consume the oil compounds. A small fraction of the oil compounds is water-soluble and thus consumed by both biofilm and free-living bacteria. C) Oil-mineral and oil-phytoplankton aggregates, which may enhance oil sedimentation ('dirty blizzards'), are formed upon interaction with sediment plumes from glaciers and phytoplankton blooms, respectively. D) Photooxidation by ultraviolet radiation from sunlight can be important, espectially during summer. Ultraviolet light helps degrading oil molecules, but at the same time, the oil toxicity towards marine organisms may increase. E) Deep mixing of the water column and upwelling cause nutrient replenishment. Oceanographical conditions may thus be important to provide fresh nutrients for oil-eating microbes.

Oil-eating microbes are challenged in the Arctic

Bacteria play a major role in cleaning up oil spills and mitigating its environmental impacts. In a review published in ‘Science of the Total Environment’, researchers from Aarhus University, Denmark, examine the major limiting factors for microbial degradation in Arctic environments.

Arms race among microbes

The hot, muddy pools of Iceland are home to a number of simple, single-celled organisms, and new research shows that they also constitute a true biological battlefield and the basis for an arms race of unprecedented magnitude. The new knowledge about the struggle between living organisms in hot pools gives us a much better understanding of how…

eLabBook Activity: Final Workshop on Research Integrity and Data Documentation
The eLabBook activity is a collaborative project in the frame of the National Data Management forum (DM- forum). In this project, research groups from KU, AU and DTU have tested (and implemented) different Electronic Lab Notebook (ELNs) software in order to evaluate how these systems can adapt to their research workflows and facilitate data documentation and sharing of data.

The welfare state: New solutions to old problems?
The welfare state is one of the greatest achievements of Western societies. Yet the welfare state is challenged. The MatchPoints Seminar 2018 brings experts from a variety of different fields together. Reseachers from the Department of Engineering will participate in workshops on welfare technology and social robots.
