"The oldest ever DNA has been found preserved in ice in Siberia.

The record-breaking samples are from plants which lived there 400,000 years ago."

"The approach gives archaeologists a new window into the past, creating a vivid picture of plant and animal diversity at the time."

"For instance, the plant DNA from Siberia suggests that tundra was once an area rich in plants that would have been able to support large herds of mammoths and other big animals. But about 11,000 years ago, the once plentiful grasses began to disappear, perhaps helping to cause the extinction of some of the large plant eaters that once roamed parts of Siberia and Alaska.

Linking the soil DNA with specific times in the past may "have major implications for many fields," including the study of ancient peoples, the authors said in the study."

Bioinformatics will be at the core of biology in the 21st century. In fields ranging from structural biology to genomics to biomedical imaging, ready access to data and analytical tools are fundamentally changing the way investigators in the life sciences conduct research and approach problems. Complex, computationally intensive biological problems are now being addressed and promise to significantly advance our understanding of biology and medicine. No biological discipline will be unaffected by these technological breakthroughs.
