Though we may often think of fossils purely as the bones of ancient organisms that roamed the Earth millions of years ago, in fact, we are actually able to see evidence of this past roaming itself.
Researchers at the College of Veterinary Medicine, Seoul National University, Korea, have created a browsable epigenetic atlas for dogs called EpiC Dog (Epigenome Catalog of the Dog) to assist with future research efforts.
The fine root (diameter ≤2 mm) is the key plant organ for nutrient and water uptake, and is also important for carbon (C) and nutrient cycling. Global warming has complex effects on vegetation dynamics and nutrient cycling ...
