Researchers at Umeå University in Sweden, led by Professor Felipe Cava, have identified a new family of enzymes that creates a unique type of cross-li....

“One of the great mysteries of biology,” says Eric Libby, former SFI Postdoctoral Fellow, now an associate professor at the Integrated Science Lab (IceLab), Umeå University in Sweden, “is eukaryogenesis, or how eukaryotes arose.” Scientists consider this to be a period of major evolutionary transition, critical to our understanding of the history and evolution of life on Earth.

Scientists at Umeå University in Sweden and the Florida Museum of Natural History used paleontological databases to build a multilaye...

Close The dispersion of vegetation is regularly used to categorize climate areas globally, still whether these areas are suitable for other organisms is unknown. Umeå experimenters have verified climate area based on the distribution of vertebrate species in recent research released by eLife.  They discovered that while elevated energy climate regions are alike across the plant and vertebrate groups, there are huge distinctions in cold and temperate climates.   Climate specifies how living organisms across the globe understand which climatic conditions propel key change in the ecosystem i...
