Ancient viral 'fossils' reveal evolutionary mechanisms
2017-06-29 06:00:00| LifeSciencesWorld
[NEWS] Studying DNA fragments left by ancient viruses in their host's genome has shown even non-autonomous viruses could prosper by helping each other. By analysing ancient viral footprints in the rice genome, Hokkaido University researchers have discovered different virus species infecting the same plant helped each other by exchanging DNA. Many viruses including “pararetroviruses (PRVs)” have the ability to insert their DNA into their host's genome. I…

Salt's secret success in ancient Chaco Canyon
2016-10-03 12:00:00| LifeSciencesWorld
[NEWS] A team of University of Cincinnati researchers had to go deep to uncover brand new knowledge that they say will “shake up” the archaeological field in the southwestern United States. Various salt compounds found deep in the soil of New Mexico's desert may be the key to understanding how crops were cultivated in ancient Chaco Canyon — despite the backdrop of what seems an otherwise arid and desolate landscape, according to a University of Cincinnati …
