- Open Source Species- Charting The Ever-Changing Genome
The genetic makeup of any species is more like customized open source code than something that is fixed and can be easily documented. The parts of our 'code' that have withstood the test of time and the parts have undergone rapid evolutionary cha ...

- One Species, Many Genomes
Faster growth, darker leaves, a different way of branching- wild varieties of the plant Arabidopsis thaliana are often substantially different from the laboratory strain of this small mustard plant, a favorite of many plant biologists. Which detailed diffe ...

- Hydra Gene Appears From Nowhere
Scientists thought that most new genes were formed from existing genes, but Cornell researchers have discovered a gene in some fruit flies that appears to be unrelated to other genes in any known genome. The new gene, called hydra, exists in only a small n ...

- Study Links NOS-3 Gene To Brain Aneurism Formation
University of Cincinnati (UC) neurovascular researchers have identified a gene that—when suppressed or completely absent—may predispose a person to brain aneurysms. Todd Abruzzo, MD, and his colleagues demonstrated that “knocking out” a gene known as endot ...

- Ancient Microbes Revived From Antarctic Ice May Be Spreading Their Genes
After being encased in Antarctic ice for 8 million years, ancient microbes thawed by a team of researchers revved up their metabolic engines again and began making proteins and replicating. These are the oldest organisms ever brought back to life after a d ...
