Human evolution tied to a small fraction of the genome
Natural selection has concentrated on a small portion of the human genome, and mostly not on genes themselves.
- Genetics
Scientists find new way to corral genetically engineered bacteria
Engineering E. coli to depend on human-made molecules may keep genetically modified bacteria from escaping into nature.
