Dog genome sequenced
Man's best friend may soon offer humans more than loyal companionship. Dogs could help scientists "sniff out" diseases such as cancer that afflict both humans and canines.

Gut reaction: Researchers define the colon's genome
For the first time, scientists have defined the collective genome of the human gut, or colon.

Chromosome rearrangements not as random as believed
A report in the Feb. 17 issue of Science by genetics researchers at The Children's Hospital of Philadelphia and the University of Pennsylvania analyzes genetic predisposition to the translocation t(11;22), a swapping of genetic material between chromosome

Patterns in genome organization may partially explain how microbial cells work
The high degree of organization of prokaryotic genomes is a complete surprise. This finding carried many implications that biologists might not have considered before.
