Nikon releases epi-fluorescence attachments for stereo microscopes compatible with a Nikon LED light source
These products allow direct coupling of Nikon’s LED light source to stereo microscopes without the need for fiber optics. Stereo microscopes are suitable for observing large samples. To observe detailed internal structures, a technique called "fluorescent observation" is used, in which features of interest are stained with fluorescent proteins such as GFP or fluorescent dyes to highlight them against a dark background. Epi-fluorescence attachments are needed to pass light...

Mixed forests can reduce the risk of forest damage in a warmer climate
Forests with few tree species pose a considerably higher risk of being damaged, and the introduced lodgepole pine is especially vulnerable. This is the finding of a new study published in Ecosphere by researchers from Umeå University and the Swedish University of Agricultural Science in Uppsala. The results can be useful for preventing forest damage and financial losses related to the forest industry.
