Scientists have visualized individual mRNA transcripts for the first time, revealing a cyclical transcription process that hits its peak in 30 minutes. The technique also shows that genes are transcribed at a limited rate by the number of polymerase/mRNA units at a gene's stopping point.

Researchers from College of William and Mary and University of Arkansas found that extreme droughts from 1587-1589 and 1606-1612 affected the Tidewater region, decimating corn crops and aggravating relations with Native Americans. The findings suggest that even well-planned colonies would have struggled under these climatic conditions.
