Highlights from the Biology of Genomes meeting
Highlights from the genome biology meeting held May 7-11 in Cold Spring Harbor, N.Y., include an enormous tree's enormous genome, genes for strong-swimming sperm, and back-to-Africa migration some 3,000 years ago.

Contest brings out the biohackers
Mix one part enthusiasm, two parts engineering and three parts biology — and you’ve got a recipe for do-it-yourself genetic engineering. Every November, college kids from Michigan to Munich descend on MIT, eager to show off their biohacking skills. In the International Genetically Engineered Machine (iGEM) competition, teams battle one another to build the coolest synthetically altered organisms. If you want to create a microbe that will sniff out and destroy contaminants in mining waste ponds, or a cell that will produce drugs right in your body, iGEM is for you.

Convenience shoulders tomato taste aside
Decades of breeding for uniform color in unripe fruit may accidentally have reduced flavor.
