The Dark Matter of the Genome
|
| Topic: Origin & Evolution of Life |
11/30/11 |
| Summary: By studying a virulent fungus, scientists have answered the question of why a single gene could come in different lengths in different individuals. It all comes down to 'spliceosomal introns.' The study could have wider implications in understanding how genes evolve. |

Bacteria are Linked Across the Planet
|
| Topic: Origin & Evolution of Life |
11/02/11 |
| Summary: Scientists have found evidence of a massive network of recent gene exchange in bacteria from around the world. The study illustrates the rapid speed with which genes can proliferate in bacteria, bypassing the time it would take for mutation to occur. |
