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.

In battle to shape immunity, environment often beats genes
The environment, especially microbes, shapes immune system reactions more than genes do.
- Animals
Squids edit genetic directions extensively
In squids, RNA editing means that DNA often does not get the final say in which proteins are created.

Bowhead whales may unlock the secrets to a long, healthy life
Analyzing the genome of the bowhead whale may help scientists understand how the animals live for more than 200 years.

The art of DNA folding
Cells must compress genetic material into a nucleus that measures only about 5 micrometers across. To accomplish the feat, cells make loops in the DNA.

The year in genomes
From the tiny Antarctic midge to the towering loblolly pine, scientists this year cracked open a variety of genetic instruction manuals to learn about some of Earth’s most diverse inhabitants.

Year in review: Genes linked to tameness
A look at the genes of domesticated animals offers possible insights into why taming has altered animals’ appearances.
