Genetic 911: Cells' emergency systems revealed Toxic chemicals wreak havoc on cells, damaging DNA and other critical molecules. A new study reveals how a molecular emergency-response system shifts the cell into damage-control mode and helps it survive such attacks by rapidly producing proteins that counteract the harm.

Chromosomes' big picture: Similarities found in genomes across multiple species; Platypus still out. By mapping various genomes onto an X-Y axis, a team of researchers has found that Charles Darwin and a fruit fly -- among other organisms -- have a lot in common genetically. The researchers found that the chromosome sizes within each eukaryotic species are actually similar rather than drastically d

Plant hormone auxin triggers a genetic switch: A mechanism for stabilizing the development of the pl During the development of organisms, a particular event repeatedly occurs: a signal appears temporarily, but the processes it triggers must be maintained -- for example, when the fate of cells in the embryo is established. The plant hormone auxin plays an important role as a signalling molecule duri
