Researchers have built a DNA barcode library for the vascular plant flora of Canada based entirely on herbarium collections. DNA barcode libraries are important to facilitate plant identification for a variety of studies including analysis and regulation of supplements, food, and environmental or ancient DNA. The scale of the study surpasses previous library-building efforts, providing barcodes for 98 percent of Canada's vascular plant species (5,076 of 5,190).https://www.sciencedaily.com/releases/2018/02/180213183617.htm
Researchers have made significant efficiency improvements to the technology used to generate solar fuels. This involves the direct conversion of energy from sunlight into a usable fuel (in this case, hydrogen). Using only earth-abundant materials, they developed the most efficient conversion method to date. The trick was to decouple the site where sunlight is captured from the site where the conversion reaction takes place.https://www.sciencedaily.com/releases/2018/01/180115121641.htm
