A new approach to amplifying DNA; A small paradigm shift within molecular photocopying
Analyzing DNA is useful for a number of vital applications. This includes diagnosis and monitoring of diseases, identification of criminals, and studying the function of a targeted segment of DNA. However, methods used for analyses often require more DNA than may be available in a typical sample. ‘Therefor, amplification is necessary, but not always straightforward. The most widely used amplification or photocopying method is the polymerase chain reaction (PCR). A new PCR method could help the amplification process, and thus develop robust assays that previously would not have been possible.

How are river ecosystems affected by regulation?
More and more rivers are regulated to serve human needs such as flood protection, transport, irrigation, hydropower generation or drinking water supply. Do altered flow dynamics affect organisms that inhabit the river bottom? And how does river flow interact with other ecosystem stressors like acidification or nutrient enrichment? A recent research project combined a flume experiment with findings from 64 regulated and unregulated river sites in Norway and Germany to find the answers.

Microplastics in agricultural soils: A reason to worry?
Microplastics are increasingly seen as an environmental problem of global proportions. While the focus to date has been on microplastics in the ocean and their effects on marine life, microplastics in soils have largely been overlooked. Researchers are concerned about the lack of knowledge regarding potential consequences of microplastics in agricultural landscapes from application of sewage sludge.
