Identical evolution of isolated organisms

(University of Erlangen-Nuremberg) Palaeontologists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and the University of Calgary in Canada have provided new proof of parallel evolution: conodonts, early vertebrates from the Permian period, adapted to new habitats in almost identical ways despite living in different geographical regions. The researchers were able to prove that this was the case using fossil teeth found in different geographical locations.

There are microplastics near the top of Mount Everest too

Researchers analyzing snow and stream samples have found evidence of microplastic pollution on Mount Everest. While the highest concentrations of microplastics were around Base Camp where hikers and trekkers spend the most time, the team also found microplastics as high up as 8,440 meters above sea level, just below the summit.

Alternative gene control mechanism based on organization of DNA within nucleus

Researchers have identified how the architecture of the cell nucleus can change gene activity in plants. This discovery reveals fundamental knowledge about genome regulation and points towards future methods for potentially manipulating the expression of many genes simultaneously.

Elephant genetics guide conservation

A large-scale study of African elephant genetics in Tanzania reveals the history of elephant populations, how they interact, and what areas may be critical to conserve in order to preserve genetic diversity of the species.

First map of bee species around the globe

There are over 20,000 species of bee, but accurate data about how these species are spread across the globe are sparse. However, researchers have now created a map of bee diversity by combining the most complete global checklist of known bee species with the almost 6 million additional public records of where individual species have appeared around the world.
